Re: Des Peres Valley #4 - Baldwin 0-6-0 using Allen Models parts.

One of the issues is that the prints don't show the reversing lever stand..

If the radius of the reversing lever quadrant is known, we can approximate the distance of the pivot point very closely (within 1/32" perhaps) and get pretty darn close.

Re: Do wheels have to be cast iron?

This is a cast iron wheel. This is a cast iron wheel that runs on steel rail, pulling a fair amount of tonnage in MOW service, and on rare occasions when needed in a pinch, a full trainset (50-60 adults). I machined new axles for this locomotive in 2009, and the wheels were fine then. YMMV. I believ...

Re: Low water mark

You mentioned that the atomizer line keeps filling with water when firing. This is likely due to condensate of steam in your atomizer line. I started the practice at the WF&P of cracking our steam-up blower hookup valve (which is at the lowest point of the cab piping) on our #534, to allow condensat...

Need to broach a square hole...

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...

Re: Alcalde & Coalfield High Line

Jack,

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

Re: Oil firing question

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...
