Joe's 1" Minne TE

That's a LOT of riveting there Joe, but the results look terrific!!  Looking forward to seeing how the spokes go in once the hub material arrives.

.... I'm starting to hate my drill-press...

Joe

Don't hate it too much, the two of you have done a great job together. Hugh.

[joe d]

Don, Bill, Hugh:  Thanks!

Decided to carry on with the front wheels while in wheel mode. (still waiting for stock for the rear wheel hubs...)

Finished up the spokes, more of the same stuff as for the rear wheels, drilled the rims for spoke locations,
and then set them up in the mill to cut with the slitting saw to simulate separate pieces of stock as the tire tread


then turned the 3 part hubs, only interesting thing there was using a ball nose mill to form a radius on the inner piece


set up the centre portion of the hubs on the rotary table to mill slots for the spokes


Then made up a jig to hold the rim and the hub in position for fitting the spokes


at that point, gave up for the day, time for a cuppa

Cheers, Joe

Got a bit more done on the front wheels

with the spokes in place held by a capscrew at the rim, went to the drill press and sequentially drilled the inner end of the spokes
where they lay on the hub, then clearance drilled and counter sunk each one, and then moved to the  pillar tool to tap the hub for retaining
screws


once that was all done, bashed in the rivets all around, chucked them up in the 4-jaw to take a little skim to ensure the hub inners were true to the axis of rotation, and then
sweated together all the hub bits


back again in the lathe to finish bore the axle hole to size, a bit of clean-up and a coat of primer and here we are


Cheers, Joe

They look the business - nice work!

Simon.

Extremely nice work. Many years ago I bought the book to build the 'Minnie' but never got to it. I'm following your progress with great interest.

Simon, George:  Thanks for looking in!

Keeping on with some front-end stuff, slit an off-cut of the boiler barrel tube to make the smoke box,


re-formed it around a piece of stock the same diameter as the boiler, and soldered in a little strip of copper to fill the gap,
and the put the handy indexing device back on the lathe to mark out rivet locations


that done, rolled a strip for the base of the perch bracket (to fit the smokebox)


bent up another piece of the same material and silver soldered them together


then bored a hole in the bottom piece to fit a brnze bushing, and milled another piece to form the pushpole fitting, and soldered them in place
with a lower temperature solder


turned and threaded both ends of 2 pieces of flat bar and riveted them in to provide studs for securing a coverplate front and back (simple hack-saw and file work for those)


milled the fork that holds the axle,


turned a retaining ring for the fork, with a tapped hole for a set screw,


turned the pin that hold the axle in the fork, and here's a peek under the cover-plate


so only have the axle, a couple of washers, and the hub covers left to do to wrap up the front wheel bits.

This is good, as my friend the mailman finally brought me the stock I've been waiting for to get back to the rear wheels!

Cheers, Joe

Very nice work, Joe. I am learning quite a bit from the wide variety of fabrications. Thanks for documenting it.

[b.lindsey]

You have made some good progress these last few days Joe. Nice pictures and documentation...its looking very nice!!!

Bill

[Don1966]

Amazing work and progress Joe and is that the rollers you made of GHT'S design?

Don

[joe d]

Thanks guys.

Hans:  I can't claim much credit for the fabrications, pretty much following the book as Mason wrote it.

Don: yes those rollers are GHT's design, they were last year's Christmas project (or was it the year before?).... still waiting for a nice day to
strip 'em down for a coat of paint.  One of these years...

I just found this thread and have pulled up a chair.

Excellent write up on one of my favorite engines.

Tom

[joe d]

Thanks Tom.  Must say that the further along I get, the more I like this engine, and I already liked it enough to start it!



chucked a piece of flat bar in the 4-jaw and turned a spigot on each end, this was then drilled and tapped for
a retaining screw.  Moved over to the mill and made some angled cuts


hand filed some decorative chamfers on the edges, some straightforward turning to make the brass hub covers


and here it is all together.


still have some cleanup to do on the axle, some filler to make the fillets where the axle meets the washer on the inside of the wheels,
but pretty much done!

Cheers, Joe

Looking good Joe, you have made fast progress over the last week or so. Don't forget the holes for the holes for the steering chain
