Re: A Little Machining Problem

I drilled them radially using the layout from the saddle.
I only had to chase them but there wasn't much material removed,

My Smokebox is split, so it was easier to clamp to the mill table.

Re: Driver Casting Repro

Rub the pattern with graphite.
That made a big difference even with 3D printed patterns.

Re: Railroad Supply History

Sorry to join this party late. After I bought my Mikado castings from Railroad Warehouse, I met Nick Edwards and he related the story behind that locomotive to me. I'll leave to others to tell the story as I'll probably forget important facts. On another note, the 6 wheel passenger trucks, pictured ...

Re: Franklin C-1 booster

I have a preliminary 3D model of a booster in 1.5/1.6" scale I intend to make for my Mikado (some day).

It's been a while since I worked on it, but I could either share it, or make the drawings for the parts.

Re: FRUSTRATED with threading tubing

I had the most trouble making close nipples. Then I found a 'solution' almost by accident. I had to remove one from a fitting and used the split die as a clamp. I put the die in a 3 jaw chuck and the nipple came out easily. OK, its not really a solution, as I didn't want to abuse an expensive die as...

Re: .032 copper tubing

The thinner wall tubing doesn't flare well if that is your connection method.

Re: Smokebox Inspection Cover

Thanks little giant,

I fully admit not have done much on the web site in quite a while. I guess I prefer to work on the locomotive ;)

I drew it in a 3D package from the pictures in the Locomotive Cyclopedia (1922 and 1941), so I hope I got it close enough.

Re: Smokebox Inspection Cover

Thanks guys, it's only taken 6 years.

The cover can be removed, but there is no hole behind it.

Off to the paint shop next.

Smokebox Inspection Cover

My first question to this forum after I joined was a source for a smokebox inspection cover. I couldn't find one and there wasn't any suggestions for one, so I drew one up myself, had it 3D printed, and cast it in bronze. I installed it this Saturday. The chain mount should be a pipe mount, but I di...

Re: Finished - sort of

Great work.

Mine has been running for 3 years (coal).
I'm in the process or providing more clearance in the trucks (they were too tight).

BTW - it's kinda out of date. More work on the loco than the web page.
