Yeah nice work Benni, you've been ploughing on with this.   :thumbup:

Looking at peoples builds with castings, I'm a bit confused as to how I'd tackle it ... what to mill and clean up and what to leave as cast finish. I guess if you don't clean it up it may look like holes are off-centre etc. Is it possible just to machine the critical dimensions and leave the rest or are the model castings not really good enough for that?

Cheers,

Nick

Thanks for nice komments Ray and NickG
NickG, I think there is two sides of youre question, some builders wants there model be very smoth and nice and other wants to show it's a casting. I am between those ideas. I want a nice and smoth model but at the same time I want to show that this model is an casting. Yes you can build a model and only machine the critical parts and it will work good, but comeing so far, I belive that you want some bling too, right?  :)

Yeah you're right, it's a balance otherwise the model could end up looking a bit average with too many cast surfaces I guess.

Hello Gentlemen!
Thanks for nice comments.

Cylinder block
Now when I have got my new tools, it’s time to move on with the cylinder block.
As you can see on the picture there is much material to remove.

http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Cylinder_block/DSCN0815.jpgBuilding Stuarts Compound Steam Engine


The first thing is too straight up the bottom so I have something to work from…

http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Cylinder_block/DSCN0817.jpgBuilding Stuarts Compound Steam Engine

… and with an end mill it is done radar quickly.

http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Cylinder_block/DSCN0819.jpgBuilding Stuarts Compound Steam Engine

I did the top at the same time and finish off with a fly cutter.

http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Cylinder_block/DSCN0823.jpgBuilding Stuarts Compound Steam Engine


Then both sides…

http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Cylinder_block/DSCN0829.jpgBuilding Stuarts Compound Steam Engine

… and even here I finish off with the fly cutter.

http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Cylinder_block/DSCN0832.jpgBuilding Stuarts Compound Steam Engine

Then some more work with the end mill.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Cylinder_block/DSCN0833.jpgBuilding Stuarts Compound Steam Engine

I took this photo true my magnifying lamp, when I marked up for the columns…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Cylinder_block/DSCN0836.jpgBuilding Stuarts Compound Steam Engine

…and I can see that the column fits very well with my smaller nuts.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Cylinder_block/DSCN0837.jpgBuilding Stuarts Compound Steam Engine

Here I marked up the centerline…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Cylinder_block/DSCN0844.jpgBuilding Stuarts Compound Steam Engine

…and I can use my new tool, the boring head. I began with the HP cylinder.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Cylinder_block/DSCN0846.jpgBuilding Stuarts Compound Steam Engine

Then reaming the cylinder…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Cylinder_block/DSCN0847.jpgBuilding Stuarts Compound Steam Engine

…and honing the cylinder.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Cylinder_block/DSCN0848.jpgBuilding Stuarts Compound Steam Engine

Then it’s time for the LP cylinder.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Cylinder_block/DSCN0850.jpgBuilding Stuarts Compound Steam Engine

Reaming, this time I have to use my lathe…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Cylinder_block/DSCN0851.jpgBuilding Stuarts Compound Steam Engine

After horning the LP cylinder I marked out the hole for the drain cocks, then drilled and threaded.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Cylinder_block/DSCN0852.jpgBuilding Stuarts Compound Steam Engine

I feel radar pleased so far.  :)

http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Cylinder_block/DSCN0854.jpgBuilding Stuarts Compound Steam Engine

Now I have to take care of the steam exhaust …
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Cylinder_block/DSCN0855.jpgBuilding Stuarts Compound Steam Engine

…and with an end mill I finish the steam passage.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Cylinder_block/DSCN0857.jpgBuilding Stuarts Compound Steam Engine

So far so good, but it’s still long way to go.  :coffee:

http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Cylinder_block/DSCN0858.jpgBuilding Stuarts Compound Steam Engine

The cylinder block was radar hard to do, many dimensions that must fit, and everything have to bestraight, but I think that I have manage that…    :med:
I’ll be back.

Nice work Benni, probably the most difficult and expensive part to make. You've done a great job on it ... I haven't tackled anything that complex from stock yet, let alone a casting  :bow:

Top Covers
Hello Gentlemen
Thanks PeterE and NickG for nice feedback.

Now it’s time to take care of the top covers. There are two, one for the HP cylinder and one for the LP cylinder.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Top%20Covers/DSCN0860.jpgBuilding Stuarts Compound Steam Engine
 
After the set up in the lathe, I clean up the bottom side, and the edge that fits in the cylinder.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Top%20Covers/DSCN0862.jpgBuilding Stuarts Compound Steam Engine
 
Then turn around and clean the edge…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Top%20Covers/DSCN0863.jpgBuilding Stuarts Compound Steam Engine
 
…and after a special setup I did the top side of the covers.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Top%20Covers/DSCN0864.jpgBuilding Stuarts Compound Steam Engine
 
Here I have done both HP and LP top cover.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Top%20Covers/DSCN0866.jpgBuilding Stuarts Compound Steam Engine
 
Now I have to find the middle of the centerline between HP and LP cylinder.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Top%20Covers/DSCN0867.jpgBuilding Stuarts Compound Steam Engine
 
When that is done I market out for the hole…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Top%20Covers/DSCN0868.jpgBuilding Stuarts Compound Steam Engine
…and drilled / threaded. Then I marked a line with a center drill because this material has to remove.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Top%20Covers/DSCN0870.jpgBuilding Stuarts Compound Steam Engine
 
Then in the round table I center drilled / drilled and finish off with an end mill.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Top%20Covers/DSCN0872.jpgBuilding Stuarts Compound Steam Engine
 
Then I placed on the cylinder block and drilled the hole.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Top%20Covers/DSCN0873.jpgBuilding Stuarts Compound Steam Engine
 
Then threaded the hole…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Top%20Covers/DSCN0874.jpgBuilding Stuarts Compound Steam Engine
 
…and check so it fits well.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Top%20Covers/DSCN0877.jpgBuilding Stuarts Compound Steam Engine
 
Then I remove some material so the two covers fits together…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Top%20Covers/DSCN0878.jpgBuilding Stuarts Compound Steam Engine
 
…and with some adjustment it will do.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Top%20Covers/DSCN0879.jpgBuilding Stuarts Compound Steam Engine
 
And this is how it looks so far.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Top%20Covers/DSCN0881.jpgBuilding Stuarts Compound Steam Engine
 
One big step for me, a small step for the Compound.  :smart:

I’ll be back.

Nice 1, I thought you'd made a boo boo and put a horrible gouge in it at one point, didn't realise the covers shared a bolt  :doh:

Very nice, looks lovely  :thumbup:

Bottom Covers

Hello Gentlemen.
Thank you NickG and Stilldrillin for very nice comments.


The story goes on, now it’s time for the bottom covers.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Bottom%20Cover/DSCN0889_zpse83875ce.jpgBuilding Stuarts Compound Steam Engine
 
First I set up the casting in my lathe…

http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Bottom%20Cover/DSCN0890_zps05ee081f.jpgBuilding Stuarts Compound Steam Engine

 
…and clean the edge and make sure that the dimension is correct.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Bottom%20Cover/DSCN0891_zps975429d5.jpgBuilding Stuarts Compound Steam Engine
 
I then clean up the bottom and center drilled…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Bottom%20Cover/DSCN0892_zps16c01e2d.jpgBuilding Stuarts Compound Steam Engine
 
 
---and drilled and reamed the hole for the piston rods.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Bottom%20Cover/DSCN0893_zps887388d1.jpgBuilding Stuarts Compound Steam Engine
 
After that I’ll use an end mille so I could get a seat for road glands for the piston rod.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Bottom%20Cover/DSCN0894_zps8e2d71f9.jpgBuilding Stuarts Compound Steam Engine
 
Here is the bottom of the HP and LP bottom cover finish.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Bottom%20Cover/DSCN0895_zps65cd1f7a.jpgBuilding Stuarts Compound Steam Engine
 
No the other side of the bottom cover, some turns on the lathe and its finish.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Bottom%20Cover/DSCN0896_zpsc72dcfae.jpgBuilding Stuarts Compound Steam Engine
 
The finish bottom cover.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Bottom%20Cover/DSCN0897_zps8073cff5.jpgBuilding Stuarts Compound Steam Engine
 
Now I have to find the centerline and the middle between the HP and LP cylinder…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Bottom%20Cover/DSCN0898_zps0184f3ab.jpgBuilding Stuarts Compound Steam Engine
 
…and then drill a hole.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Bottom%20Cover/DSCN0899_zpsf58735d9.jpgBuilding Stuarts Compound Steam Engine
 
Now I have the distance so I can continue on my round table.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Bottom%20Cover/DSCN0900_zps9b6d1d73.jpgBuilding Stuarts Compound Steam Engine
 
After drilling and easy using an end mille both cover is now finish.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Bottom%20Cover/DSCN0901_zpsc1d26534.jpgBuilding Stuarts Compound Steam Engine
 
Then I marked up where to drill on the cylinder block.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Bottom%20Cover/DSCN0902_zpsa9299111.jpgBuilding Stuarts Compound Steam Engine
 
Then threading the hole...
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Bottom%20Cover/DSCN0904_zps7d09460e.jpgBuilding Stuarts Compound Steam Engine
 
...and mount the studs.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Bottom%20Cover/DSCN0906_zps641d07ef.jpgBuilding Stuarts Compound Steam Engine
 
After that I remove some materials so the covers fit together.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Bottom%20Cover/DSCN0907_zpsea2e5988.jpgBuilding Stuarts Compound Steam Engine
 
And then I have to check so I could mount the bottom cover to the cylinder block.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Bottom%20Cover/DSCN0908_zpsf6fee0df.jpgBuilding Stuarts Compound Steam Engine
 
And now the machine has both hats and pants on.  :headbang:
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Bottom%20Cover/DSCN0909_zps7c2c182f.jpgBuilding Stuarts Compound Steam Engine
 
Both the top cover and the bottom cover were a little tricky to maintain, but I took my time and so far I can’t see that I have done some wrong.  I hope that I never got to see that…  :coffee:

I’ll be back.

Nice work Benni, the only one thing I may have possibly done the other way around was to drill and ream the piston rod holes at the same time as you turn the register - only because that way you're not relying on the run out in your lathe to get them concentric - however, doing it my way, you cant do the counterbore for the gland at the same time as the hole, so guess you can't have it both ways anyway.

I reckon it'll be fine, a chuck is usually within a thou or two so you'll probably just give enough clearance on the hole size.

Crosshead_Guides
Hello Gentlemen.
Now it’s time for the crosshead guides.
The crosshead guides serves to connect the bottom covers to the bracket and allow the crosshead to run in a groove for guiding the connecting rod so it runs straight.    :smart:

The crosshead guides is made of steel.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crosshead_Guides/DSCN0918.jpgBuilding Stuarts Compound Steam Engine
 
First I have to part of the steel plate and mark up for the hole…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crosshead_Guides/DSCN0920.jpgBuilding Stuarts Compound Steam Engine
 
…and then drilled to the right size.
 http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crosshead_Guides/DSCN0921.jpgBuilding Stuarts Compound Steam Engine

Then find the centerline and mark it…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crosshead_Guides/DSCN0922.jpgBuilding Stuarts Compound Steam Engine
 
…and mille the track.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crosshead_Guides/DSCN0923.jpgBuilding Stuarts Compound Steam Engine
 
Here I have done both crosshead guides.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crosshead_Guides/DSCN0924.jpgBuilding Stuarts Compound Steam Engine
 
Next job is to mill the underside of the bottom cover so I got the accurate measure. ..
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crosshead_Guides/DSCN0925.jpgBuilding Stuarts Compound Steam Engine
 
...and drill the hole for the crosshead guide.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crosshead_Guides/DSCN0926.jpgBuilding Stuarts Compound Steam Engine
 
Then threading the bottom cover…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crosshead_Guides/DSCN0928.jpgBuilding Stuarts Compound Steam Engine
 
…and drilled the bracket…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crosshead_Guides/DSCN0929.jpgBuilding Stuarts Compound Steam Engine
 
 
…and threading again.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crosshead_Guides/DSCN0930.jpgBuilding Stuarts Compound Steam Engine
 
Then mount the crosshead guides between the bottom cover and the bracket.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crosshead_Guides/DSCN0932.jpgBuilding Stuarts Compound Steam Engine
 
Now it looks like my Compound has got his suspenders…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crosshead_Guides/DSCN0933.jpgBuilding Stuarts Compound Steam Engine
 
These operations took some time but whom is in hurry…  :lol:

I’ll be back

Drain Cocks.
Hello Gentlemen.
Thank you rleete and NickG for nice comments.
You may think I'm a little crazy but I have decided to continue this building blog with the drain cocks.
This drain cock is a tip from my Canadian friend Mr. John Bentley.

The drain cocks are very important equipment for the live steam engine. Its main task is to prevent the water stays in the cylinder, so it must be opened on when you start the machine, and then close it. Similarly when to stop the machine, you have to open to prevent water stay left in the cylinder.
First I start up with a brass bar and a small drawing how the body should be…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Drain%20Cocks/DSCN0882.jpgBuilding Stuarts Compound Steam Engine
…then some turn on the lathe for the threading…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Drain%20Cocks/DSCN0883.jpgBuilding Stuarts Compound Steam Engine
…and then I did the threading.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Drain%20Cocks/DSCN0884.jpgBuilding Stuarts Compound Steam Engine
Then I drilled a hole …
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Drain%20Cocks/DSCN0885.jpgBuilding Stuarts Compound Steam Engine
…and some more turns on the lathe so I got this shape.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Drain%20Cocks/DSCN0886.jpgBuilding Stuarts Compound Steam Engine
Here I test so the threading is correct.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Drain%20Cocks/DSCN0887.jpgBuilding Stuarts Compound Steam Engine
And here I have done all four of them.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Drain%20Cocks/DSCN0888.jpgBuilding Stuarts Compound Steam Engine
In the drill I needed to find the center…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Drain%20Cocks/DSCN0911.jpgBuilding Stuarts Compound Steam Engine
…and then the middle…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Drain%20Cocks/DSCN0912.jpgBuilding Stuarts Compound Steam Engine
…then drill the hole.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Drain%20Cocks/DSCN0913.jpgBuilding Stuarts Compound Steam Engine
Of silver steel I made a tapered reamer so I can have a tapered hole…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Drain%20Cocks/DSCN0914.jpgBuilding Stuarts Compound Steam Engine
 …and finish off with a bottom pin for a fine surfers.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Drain%20Cocks/DSCN0916.jpgBuilding Stuarts Compound Steam Engine
Here are the finish bodies.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Drain%20Cocks/DSCN0917.jpgBuilding Stuarts Compound Steam Engine
And now I have to deal with the plug, first in the lathe and run a few turn for the threading…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Drain%20Cocks/DSCN0933.jpgBuilding Stuarts Compound Steam Engine
…and for tapping...
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Drain%20Cocks/DSCN0934.jpgBuilding Stuarts Compound Steam Engine
…and some more turns on the lathe…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Drain%20Cocks/DSCN0935.jpgBuilding Stuarts Compound Steam Engine
…then threading.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Drain%20Cocks/DSCN0936.jpgBuilding Stuarts Compound Steam Engine
Then I have to check so the plug fits well in the body.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Drain%20Cocks/DSCN0937.jpgBuilding Stuarts Compound Steam Engine
Then I have to bend it with some heat.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Drain%20Cocks/DSCN0938.jpgBuilding Stuarts Compound Steam Engine
Then I have to make some washers, springs and nuts.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Drain%20Cocks/DSCN0940.jpgBuilding Stuarts Compound Steam Engine
Then I mount the drain cock and put it in the drill so I can drill true the plug.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Drain%20Cocks/DSCN0941.jpgBuilding Stuarts Compound Steam Engine
And here all of the drain cocks are mounted on the cylinder block.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Drain%20Cocks/DSCN0942.jpgBuilding Stuarts Compound Steam Engine

This was a very fun equipment to make not so hard to do, but very small.

I’ll be back.

Hello Gentlemen and thanks for nice feedback.  :thumbup:
 
Pistons, pistons road and cylinder glands.

Now it’s time to take care of the heart of the steam engine, the powertrain. It’s about the pistons, the piston road and the cylinder glands.
Pistons:
The pistons are casting in very good quality.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Pistons/Pistons_944.jpgBuilding Stuarts Compound Steam Engine
 
The first thing I did, was setting it up in the lathe and took some turn to flatten the top.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Pistons/Pistons_945.jpgBuilding Stuarts Compound Steam Engine

Then some more turns to make the 45 degree angle
And then I did the edge.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Pistons/Pistons_946.jpgBuilding Stuarts Compound Steam Engine
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Pistons/Pistons_947.jpgBuilding Stuarts Compound Steam Engine
 
Next I drilled and threaded for the pistons road.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Pistons/Pistons_948.jpgBuilding Stuarts Compound Steam Engine

 
And then turn the casting round and turn the edge, bottom and inside of the pistons.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Pistons/Pistons_949.jpgBuilding Stuarts Compound Steam Engine

Then I made a little mandrill so I could mount the piston. Then turn the piston down to the correct dimension and then cut the track for the piston rings.
 
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Pistons/Pistons_950.jpgBuilding Stuarts Compound Steam Engine
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Pistons/Pistons_951.jpgBuilding Stuarts Compound Steam Engine
 
And here I have done the both pistons.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Pistons/Pistons_954.jpgBuilding Stuarts Compound Steam Engine
Piston road
The piston roads are made from silver steel…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Pistons/Pistons_955.jpgBuilding Stuarts Compound Steam Engine
 
…and have to cut off in a proper length and turn down in the both ends for threading.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Pistons/Pistons_956.jpgBuilding Stuarts Compound Steam Engine
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Pistons/Pistons_957.jpgBuilding Stuarts Compound Steam Engine
 
Then I have to cut down a little bit so that threading fits the piston.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Pistons/Pistons_958.jpgBuilding Stuarts Compound Steam Engine
 
This was a very easy job and it also fits the piston well.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Pistons/Pistons_959.jpgBuilding Stuarts Compound Steam Engine
 
Cylinder glands.
The cylinder glands are made of bronze…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Pistons/Pistons_960.jpgBuilding Stuarts Compound Steam Engine
 
…and first I have to use a hacksaw to cut it in two pieces.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Pistons/Pistons_961.jpgBuilding Stuarts Compound Steam Engine
 
Then in the lathe some turns so I have a good surfers and then center drill, drilled and threaded so I can mount it on a mandrill and finish of the bottom side.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Pistons/Pistons_962.jpgBuilding Stuarts Compound Steam Engine   
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Pistons/Pistons_964.jpgBuilding Stuarts Compound Steam Engine
 
Next I have to mark and drill the holes for mounting the glands to the bottom cover.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Pistons/Pistons_965.jpgBuilding Stuarts Compound Steam Engine
 
Then I set up the cylinder, bottom cover and gland on the mill for drilling and threading.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Pistons/Pistons_966.jpgBuilding Stuarts Compound Steam Engine
 
And then testing so the glands fits well.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Pistons/Pistons_967.jpgBuilding Stuarts Compound Steam Engine
 
After a bit of filling and emery cloth, then back to the lathe for drilling and reaming.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Pistons/Pistons_969.jpgBuilding Stuarts Compound Steam Engine
 
And again check so it fits well.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Pistons/Pistons_970.jpgBuilding Stuarts Compound Steam Engine
 
And now another piece is finish on my compound.

She is beginning to look radar pretty, isn’t she?  :D
I’ll be back

Still drilling holes... Sometimes, in the right place!

Still modifying bits of metal... Occasionally, making an improvement!

Crossheads
Hello Gentlemen.
Thanks Stilldrillin for nice comments.
Today I continue with the crosshead, not a major update but a very important part of the engine.
The crosshead is connected between the piston road and Connecting Rods and in a groove in the Crosshead Guides.
The crosshead is a very fine casting made of bronze.

http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crossheads/Crossheads_972.jpgBuilding Stuarts Compound Steam Engine
I began with a setup on my mill, and square the part.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crossheads/Crossheads_973.jpgBuilding Stuarts Compound Steam Engine
 
Here I have done all of the four side of the crosshead.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crossheads/Crossheads_974.jpgBuilding Stuarts Compound Steam Engine
 
Then I move the crosshead to the lathe and make the connecter for the Piston Road.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crossheads/Crossheads_975.jpgBuilding Stuarts Compound Steam Engine
 
After center drill, I have to drill a hole…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crossheads/Crossheads_976.jpgBuilding Stuarts Compound Steam Engine
 
…and threading for the Piston Road.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crossheads/Crossheads_977.jpgBuilding Stuarts Compound Steam Engine
 
So far I’ll get this.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crossheads/Crossheads_978.jpgBuilding Stuarts Compound Steam Engine
 
Then some more turns on the lathe for that part that fits the groove in the Crosshead Guides and  then drilling/treading.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crossheads/Crossheads_979.jpgBuilding Stuarts Compound Steam Engine
 
And now I can check so I know that it fits well.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crossheads/Crossheads_980.jpgBuilding Stuarts Compound Steam Engine
 
Next drilling for the hole to the Connection Road…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crossheads/Crossheads_981.jpgBuilding Stuarts Compound Steam Engine
 
…and then I have to mill the edges straight.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crossheads/Crossheads_982.jpgBuilding Stuarts Compound Steam Engine

And after some filling and polish I’ll get this.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crossheads/Crossheads_983.jpgBuilding Stuarts Compound Steam Engine
 
Mounted on the engine, the backside looks like this…
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crossheads/Crossheads_984.jpgBuilding Stuarts Compound Steam Engine

…and then the other side.
http://i1123.photobucket.com/albums/l558/Benni_Svensson/Stuart%20Compund/Crossheads/Crossheads_985.jpgBuilding Stuarts Compound Steam Engine
 
Even this miner update was little tricky because all dimension has to be correct and the angel must be straight, in other words I have to do some small adjustment but now I am pleased.   :)
 
I’ll be back.
