Minnie TE Long term project

[vtsteam]

Just catching up Joe --- you're such an inspiration. You make it all look easy, and it just keeps coming, part after part, little bits of art. I love watching this project. 

[Joe d]

Thanks, Steve.  That's how I've been regarding your lathe project.... time for some updates there, my friend!

Started work on the steering gear, turning the drum for the steering chains.  I have a bolt-on chuck,
so I can run the lathe in reverse to use the ball-end mill "upside down" to make the curve on the right end of the stock
Minnie TE Long term project

Once the other end was done, parted it off and moved to the taig lathe to finish it off, the steady on the big lathe is way too big for this job
Minnie TE Long term project

Moved to the mill to cross-drill for the chain bolts, and milled a flat for the nuts, you can see one of the mounting brackets, straitforward
drilling and filing, with a bronze bushing soldered in, and the worm with it's shaft which will be locked in place by  the eyebolt
Minnie TE Long term project

here it is with the chains rigged
Minnie TE Long term project

and here with the steering shaft installed
Minnie TE Long term project

Sad to say that the worm and wheel which are some of the very few parts I've bought ready made, do not in fact mesh...seems to be a slight difference in pitch.  So, will have to replace them, or learn to cut my own....

Cheers, Joe

Finishing off the steering business, need a steering wheel...

Some faceplate turning:
Minnie TE Long term project

off the faceplate, cut out the bits that don't look like spokes, soldered in a small piece of round stock
to act as the boss for a handle
Minnie TE Long term project

Hacksawed off the greater part of the excess on the outside of the rim, mounted the wheel on a little stub of rod threaded to
fit, into a collet on the taig lathe and a lot of very small cuts to true it up
Minnie TE Long term project

a quick little bit of turning and threading for the handle, and here it is
Minnie TE Long term project

Moved on to the blower valve, turned a bit of bronze to size, threaded the outside for the bonnet, drilled and tapped it for the spindle,
and moved to the mill to cross-drill for the inlet and outlet while still on the parent material
Minnie TE Long term project

Cut it off, and put it in a collet to trim to size and drill it out for the insert with the various passages required
Minnie TE Long term project

Having neglected to take any pictures of the inserted bit, here it is with the insert and the inlet/outlet pipes (simple turnings, threaded
and through drilled) silver soldered in place, and the bonnet nut, the spindle turned from some stainless, and the handwheel & nut
Minnie TE Long term project

Those of you familiar with the "words and music" as written by Mason will recognize that I'm really going back and forth with
regards to the order of construction here, simply a question that I tended to skip ahead when missing the material for various bits.
I've now received what should be the LAST order of material for the project, so am catching up... will now go to the valve & piston rods, a piston, and then we'll be in the happy position of running the first test on air!

Joe

[Joe d]

made up the rod for the valve ... just a question of threading it on each end with a lock nut
Minnie TE Long term project

and installed it
Minnie TE Long term project

and then 2 pieces for the regulator
Minnie TE Long term project

fitted up the crosshead guide bars, simply some flat stock with a threaded bit on one end to fit into the flange on the cylinder head
Minnie TE Long term project

Turned the piston from cast iron, I've grooved it for some piston rings as somehow I neglected to get the correct size
of O ring (can always go back and redo if I don't like how it works with the rings)
Minnie TE Long term project

turned and parted off  some rings
Minnie TE Long term project

The piston rod is just a bit of Stainless threaded on both ends, here's the family shot:
Minnie TE Long term project

and where it belongs:
Minnie TE Long term project

Chasing down a little binding with the crosshead, once I've got that sorted out, have to make up a temporary inlet fitting and fire up the compressor !

cheers, Joe

      We have a RUNNER!

After a fair bit of mucking around with valve settings and leaking gaskets,
it works...

It's all downhill from here... once I stop grinning enough to get back to work.

Cheers, Joe

Joe, the running video comes up as "the video is no longer available the YouTube account associated with this video has been closed"
JD

[Stilldrillin]

Looking forward to watching all those parts, running together in harmony, Joe. 

David.

[Joe d]

JD, David:  The video should be back... For unknown reasons, youtube shut it off,
 for equally unknown reasons, they've turned it back on...

Joe

[Stilldrillin]

That's a fine sight! 

Well done, Joe....... 

David.

[RobWilson]

    Nice one Joe 


Rob

[tom osselton]

Well done!

[Joe d]

   David, Rob, Tom; have one on me!  Thanks guys.

Dug out the casting for the boiler feed pump that has been gently maturing on the workbench
for a couple of years now.

A couple of passes with a fly-cutter to start squaring up the sides
Minnie TE Long term project

once done, flipped it over and did the other side, then cleaned up the face of the flange for the pump ram
Minnie TE Long term project

Cleaned up the top face with an end mill, and drilled several through holes for various water passages. While there, drilled and reamed for the ram
Minnie TE Long term project

You can see where the pattern maker
lost track of the idea that the boss on the bottom of the casting SHOULD be in line with the flanged bit...
Minnie TE Long term project

So, cut off the boss, which at least let me use a flycutter to clean up the bottom face, counter bored the hole
Minnie TE Long term project

Turned, drilled, tapped  a bit of bronze,
Minnie TE Long term project

and silver soldered it in place
Minnie TE Long term project

It's been in the pickle overnight, so will get back at it later today.

Cheers, Joe

[awemawson]

A nice recovery there Joe 

[Joe d]

Thanks, Andrew.

On a completely unrelated note, now that the first winter has nearly passed by, how are
the pigs making out in that palace of a shelter you made them?  Fit for the task, as well
as a good-looking building?

Cheers, Joe

Well Joe, Blossom the Sow had her boyfriend Robert to stay for a couple of months, their nuptials being in the new sty 

He's now gone home and hopefully we'll hear the patter of tiny trotters end of March / early April. I now need to pressure washer / steam clean out the original sty, as it's been unoccupied during that time and without their constant nuzzling has gone rather green. It wont be used until the latest batch of offspring are ready for weaning.

Apparently Robert got his picture on the local news where he lives, as he sired a litter that was born on Christmas Day 

[Joe d]

Well... seems it's been a while.  Few bits of life getting in the way of shop time, but it's getting back to normal now.

Picked up with the water pump;

another bit of not-quite on pattern making left one of the bolt holes for securing the pump to the boiler hanging out in the air
so I counter-bored it,
Minnie TE Long term project

and soft-soldered in a bit of round stock
Minnie TE Long term project

sawed off the excess, and ran the flycutter over it all to even it out.  You can see the result here, where I am drilling the flange for the
gland using the gland to spot the holes
Minnie TE Long term project

then filed down the flange to match the gland, made up some bronze bolts and some simple turning of some stainless
for the ram
Minnie TE Long term project

and here it is in place
Minnie TE Long term project

The pipe unions and the square headed valve cover screws were made up of some bronze, this occasioned some delay as the die I used for the unions broke threading the very first one... the new one works just fine...

Started on the eccentric strap earlier today and buggered it already, so will start over tomorrow.

Cheers, Joe

[Joe d]

Well, second time was the charm...

Set up in the lathe for boring out the centre...(never got this far on the 1st attempt, I'd split the material and then drilled
for the fasteners, and went off all squint with the holes, nothing matched up.  This time I drilled first and then split the
material, cleaned up the mating faces and carried on)
Minnie TE Long term project

hacksawed off most of the waste, then cleaned up in the mill
Minnie TE Long term project

some sawing,  filing, and drilling for the arm and then riveted in place (I had turned the eccentric when I did the ones for the valves)
Minnie TE Long term project

And where it all goes
Minnie TE Long term project

Made up the valve for the tender tank feed to the boiler pump...

first turned various bits from bronze
Minnie TE Long term project

silver soldered the inlet & outlet pipes to the valve body, then into the mill to drill and tap for the valve top, which is internally threaded for
the spindle
Minnie TE Long term project

Then drilled through the inlet and outlet pipes, that I had not yet through drilled when they were soldered into place
Minnie TE Long term project

and then some straightforward turning and threading of a bit of stainless for the spindle, which then had some piano wire soldered on
as an extension so that it will reach over the top edge of the tender.  Once in place, and with the brake handwheel assembly installed,
the end of the extension will be bent over to horizontal to act as a handle
Minnie TE Long term project

Cheers, Joe

[Joe d]

Bent up a little bracket from some brass, tinned the back face, drilled the tender and applied a bit of flux, and secured it with some scale lag bolts that cheerfully acted as self-tapping sheet metal screws.. which were well coated with flux before screwing into place.
Then gently heated until the soft solder flowed.  All that as I neglected to realize I had this bracket to install back when I was making the tender,
where it would have been less worrying that I might bugger the seal in the tender's bottom joint with more soldering...
From the outside at least, all appears well
Minnie TE Long term project

Threaded the end of some steel rod, and then using the collet as a depth stop (which you can't see on the other end of the vise), machined a flat on opposite sides, and drilled through to fit
the extension on the valve spindle
Minnie TE Long term project

Cut the above from it's parent stock, rounded the cut end, drilled the tender side for it, and here we are:
Minnie TE Long term project

Really starting to close in on the end now!

  Looking great Joe   

I am looking forward to seeing the engine complete .


Rob

[krv3000]

hi that's shaping up nice

[Joe d]

Rob, KRV, Thanks lads.

About time you got back to yours, eh Rob?

Joe

[RobWilson]

About time you got back to yours, eh Rob?

Joe

Maybe one day Joe ,I  must admit I more interest in watching  your build  progress

Do you have a name for her ?


Rob

[Joe d]

Hi Rob... Haven't nailed it down yet, but probably will go all traditional and name it GEORGE after my Dad...

Made up the throttle lever and rod, didn't take any piccys, just straight forward turning of one threaded bit to fit the valve rod, and
mill out a clevis for the other end, the lever is flat bar with a turned handle soldered on, and the bracket was a soldered together fabrication
of flat bar as well. In place here, with some temporary fasteners
Minnie TE Long term project

moved on to the blow-down valve, turned and threaded a bit of bronze, parted it off and screwed it into a bit of spare ali in the small lathe (that was drilled and tapped in place so it is concentric with the spindle) turned down the now exposed other end, threaded it, moved the
chuck to the dividing head in the mill to mill the flats to form a hex (all this as I didn't have any hex bronze in the pile)
Minnie TE Long term project

Turned, threaded, and parted off the spindle, also a bit of bronze
Minnie TE Long term project

some straight forward turned and tapped bits as well,
Minnie TE Long term project

soldered together,
Minnie TE Long term project

assembled, and in place:
Minnie TE Long term project

and now it's time for a cuppa and a smoke....

Joe

[Joe d]

Well, squeezed in some shop time,  got to work on the grate and the ash pan

sliced up some stainless, drilled, turned some spacers, cut some rod to assemble it all on
Minnie TE Long term project

Stacked up with the ends of the rods peened over
Minnie TE Long term project

The ash pan was folded in the bench vise, and the corners silver soldered, riveted in supports for the grate, made up the damper and soldered on some hinges filed up out of sheet steel, and soldered heads on some rods as pins
The control rod for the damper is piano wire with a slotted bit of flat stock soldered in
Minnie TE Long term project

And here it is where it lives:
Minnie TE Long term project

I'm not to crazy about the locking handle as drawn, so I will most likely make up something a little more in keeping with the look of the engine


And now have turned to some of the brown stuff: need to make up the blocks for the brake

turned some nice dry hard maple:

Minnie TE Long term project

Set up my handy-dandy toolpost that lets me turn stuff to the extreme edge of the Taig's envelope, and parting off a ring of the maple
Minnie TE Long term project

and here it is
Minnie TE Long term project

this will be cut into small segments and fastened to to the brake band....
