Engine builders allways leave little on himself on every engine he builds: usually it is blood.

Title: Re: Big Marine Steam Engine
Post by: doubleboost on June 12, 2011, 01:13:03 PM: Time for a crank shaft
I was going to build a disc type (nice and easy) then Rob Wilson recond a built up crank would be easy :) :) :) :) :)
The engine will have a 3.4 inch stroke so the crank will be a nice meaty job

The 2 webs were welded together then machined in to submission
(http://i261.photobucket.com/albums/ii63/john970s0/P6040035-1.jpg)

(http://i261.photobucket.com/albums/ii63/john970s0/P6040041.jpg)

(http://i261.photobucket.com/albums/ii63/john970s0/P6040036.jpg)

A bit of en8 bar wea turned up for the big end 7/8 diamiter with 3/4 shoulders 3 thou interfierence fit in the webs
(http://i261.photobucket.com/albums/ii63/john970s0/P6040051.jpg)

25 mm stainless bar for the mains this was turned between centers (my first attempt at this )_
Turned down to be a nice fit in the webs then a 3 thou press fit

(http://i261.photobucket.com/albums/ii63/john970s0/P6070012.jpg)

(http://i261.photobucket.com/albums/ii63/john970s0/P6070013.jpg)

Rob pressed the job together for me 10 ton was mentioned.

Just to make sure i welded it as well

(http://i261.photobucket.com/albums/ii63/john970s0/P6070017.jpg)

Back between centers for a final clean up

(http://i261.photobucket.com/albums/ii63/john970s0/P6080031.jpg)

(http://i261.photobucket.com/albums/ii63/john970s0/P6080024.jpg)
Welding allowed me to put fillets on the webs

(http://i261.photobucket.com/albums/ii63/john970s0/P6080029.jpg)

To say i am pleased with the finished job would be a understatement

(http://i261.photobucket.com/albums/ii63/john970s0/P6090006-1.jpg)

(http://i261.photobucket.com/albums/ii63/john970s0/P6090003.jpg)

Even took some video of it going around

(http://i261.photobucket.com/albums/ii63/john970s0/th_P6090005.jpg) (http://s261.photobucket.com/albums/ii63/john970s0/?action=view&current=P6090005.mp4)

Deceded to make the piston :dremel: :dremel:
Thought about using O rings :bugeye: :bugeye: :bugeye: hopefully this engine will see steam so proper piston rings it is :) :) :)

Post by: doubleboost on July 20, 2011, 05:45:15 PM: Hi
Got a little bit more done
I needed a lump of bronze flat bar 1 inch thick by 3 inches square for the big end
It is nice to have a furnace
(http://i261.photobucket.com/albums/ii63/john970s0/P7200008.jpg)
Flat bar cast up
(http://i261.photobucket.com/albums/ii63/john970s0/P7190040.jpg)
Machined to size cut in half then bored to fit the crank pin (i turned a dummy pin to dead size and one .001 smaller)
To use as test pieces
(http://i261.photobucket.com/albums/ii63/john970s0/P7200012.jpg)
Very happy with the fit Jjust nipping but still free enough to turn)
(http://i261.photobucket.com/albums/ii63/john970s0/P7200015.jpg)

Title: Re: Big Marine Steam Engine
Post by: lordedmond on July 23, 2011, 04:07:08 AM: How will the CI ring wear in the bronze cylinder ?

I have only used CI rings in CI cylinders , I do use 'O' rings in bronze or soft packing

Nice work BTW I am not criticising just asking as I am knocking up a triple expansion engine that uses a bronze block and bronze rings , I an thinking of using CI as i know it will work

Post by: Mike Cole on July 23, 2011, 03:41:00 PM: Very nice work, I am very inpressed with the crank. is this engine going in a boat when finished?

Mike
Title: Re: Big Marine Steam Engine
Post by: doubleboost on July 23, 2011, 05:07:07 PM: Hi
Stuart
I think the iron rings and piston should work ok
(if anyone has views i would like to hear them)

Mike
It would certainly power a boat but sadly i have no room for one

Rotary tables are a steep learning curve
Pleased with the result though

(http://i261.photobucket.com/albums/ii63/john970s0/P8040367.jpg)

I had a feeling this was inside the other half of this block
The hard bit is getting it out :doh: :doh:

A bit of taper turning and some file work

Drill and tap one end screw cut the other and set to length.
They looked ok but very plane

Post by: madjackghengis on August 09, 2011, 11:22:20 AM: Very nice job going on here, I like to see an engine come together with each part dictating what comes next, and the ability to decide on the fly, how to do each little bit. It makes for a very personal engine, and I have to say, you are going to need a real boiler for that job, when it is finished. :beer: Cheers, Mad Jack

Bottom cylinder cover machined

I had a lesson in marking out as the hole centers for the colums are very critical

Post by: doubleboost on September 16, 2011, 05:24:59 PM: Hi
Got a big bit done it is nearly a runner
Time for a fly wheel
I had a 8 inch disc with a hole in it about the size i wanted but a bit thin
A centre boss was turned up on my boxford
The big bit was possible for me to machine but it would have taken a long time
Rob Wilson kindly offerd to rough it out for me on his referbished cub lathe
(Robs idea of roughing out is different from mine) needless to say it turned out perfect.
(http://i261.photobucket.com/albums/ii63/john970s0/P9160154.jpg)
Time to cut a key way in the crank
(http://i261.photobucket.com/albums/ii63/john970s0/P9150150.jpg)
The proportions are just right
(http://i261.photobucket.com/albums/ii63/john970s0/P9160156.jpg)
Could not resist making it spin around

Well John, I'll second that!! You've got a very nice setup there, the whole build was a piece of work to watch and enjoy, I envy your boiler, getting a steamer up and having a boiler sitting ready to fire up is a treat to all who have been watching, and wishing to hear her run, as well as see her. Air doesn't replace steam, but only gives a hint of what the steam will do. Very fine work on the patterns, the castings, on top of all the fine machine work. I hope to have a furnace at the end of the winter so I can do some casting. It looks to change everything. I know how hard I have to look to find bits and pieces that will fill the hole, and being able to cast exactly the right part has to be the cat's meow. Sure wish I could smell the steam and the burnt oil smell that goes with it. :bow: :jaw: :bugeye: :beer: Cheers, on a very fine job showing how it's done. mad jack

The box and lid are brass plate
The hinge is some brass tube silver solderd on with a stainless welding rod as a pin

Time to finish this engine
After a couple of hours running i took it apart tonight
No wear at all on any of the bearings the cylinder and rings are bedding in nice
Machined a recess in the base plate for the reverse eccentric (time to make it go backwards)

:jaw: :jaw: :jaw: :jaw: :jaw: :jaw: :jaw: :jaw: :jaw: :jaw: :jaw: :jaw: :jaw: :jaw: :jaw: :jaw: :jaw: :jaw: :jaw: :jaw: :jaw: :jaw: :jaw: :jaw: :jaw: :jaw: :jaw: :jaw:

Love the casting work, love the machining work, love the look of the whole thing (hmm, except for that crosshead block, I'd have made it curved to match the other bit - but hey, that's such a tiny nitpick it barely deserves a mention and besides, it's much better machining than I've ever done), and I especially love the sound it makes on steam at low RPMs - exactly like a steam locomotive.

Absolutely fabulous work, John, if I can be 10% as accomplished as you then I will feel like I'm on top of the world.

Blast from the past MOWOG ..

On some of the castings .. long time ago a lad I worked with had a ( Morris ??? BMC ??? ) engine to power his Narrow Boat ... I remember MOWOG on that when we rebuilt it ..

Being a Biker I was amazed at pinch bolts on the little end of the con-rod .. No idea whether that was peculiar to the Marine ...( canal boats marine ? ) engine or not .

Not a BL fan myself .. had a Marina 1.8 Estate for 7 weeks ... absolute camel .. :bang:

I was wondering as well but I would venture a guess and say that it means Dave #4 or D4 seeing as there are so many guys named Dave.

My son has 3 close friends that are called Dave. When ever we talk about them we say Dave, D2 or D3. That is the only way we can keep them straight without having to use last names.
