The Home Machinist!

Hi all, I'm working on a electro-pneumatic semaphore signal for a railroad. I've been asked to machine new bushings for the shaft. My issue is the shaft is a 3/4" square shaft. I am trying to determine the best way to broach this opening. The bearing will be 1-3/8" in length, which is a pretty subst...

Beautiful, Jack. Motivation for me to keep going on my projects. Would like to visit your track one day.

Jack,

If you are willing to divulge, how much would you say it costs per Pylon to build?

I do not think that your fuel is viscous enough to require pressurizing the tank. Simply having your tank sitting on top of your water tank on your tender should be sufficient. Gravity feed is your friend. It is also safest. We gravity feed at the WF&P. It does just fine. We do have the occasional i...

I think it is safe to say that once you have seen it happen, or you have done it, it is a lesson learned. Earlier this year - I watched a gentleman who is getting up there in age, try to hostle an engine over to its train. Snuffed the fire right out. He got out of the engine, went to get his oil wic...

Yes - but I wanted to make sure I understand correctly. The notes say to modify 'C' to suit, while maintaining 1/8" Lap. With the amount of core fins that is present, I think I will be over the 0.250" port dimension when I clean up. Also, the notes call for a 3/8" distance between the cavity inside ...

Hello, I'm working on a set of Allen Mogul cylinders. The dilemma I have right now is that the ports have been cored strangely. As it stands now, the port dimensions that I'm coming up with are oversize, not because of the actual core, but there was a core fin remaining, resulting in the edge of the...

I guess it depends how you set up your cylinder. Are you talking about working on the bore surface, or are you talking about the different faces of the cylinder itself? IE Valve Surface, Cylinder Saddle Mating surface, etc...?

Ratchet and Pawls for 12"/15" would be nice. McMaster charges an arm and leg, last I checked.

Hi all, I came across an ad for coal and I will be driving by there on a trip over Labor Day weekend, so I'm considering stopping and picking up a few buckets to try it out.... But wanted to ask the brain trust as to what I should be looking for.... The ad states this, and nothing more regarding cha...

The Wabash, Frisco and Pacific is in Glencoe, Missouri, NE Kansas. 12 locomotives, scheduled weekend service. All volunteer, live steam club operation. Largest collection of operating 12” gauge locomotives in the world, I think.

Er.... Glencoe, MO... Not in NE Kansas.
