Re: Steam Pump need help identifying

RN - wow, that is an awesome achievement, making a pump from scratch! Id love to see a “build thread” on that, have you posted about it anywhere? Bill C. No build thread on my dummy pump. I started with castings sold by Railroad Warehouse (Nevada), but they are no longer in business. Someone purcha...

Re: Steam Pump need help identifying

Bill:
No, I do not know where to get plans.
I used photos of the real pumps to scale sizes and details.
And I built it to 1/8th scale.
Yes, it's a dummy. Like me, sometimes...

Re: Steam Pump need help identifying

I concur that the castings are probably for a dummy pump, not a working one.
Here's are pics of what can be done with similar castings, without plans or drawings.

Re: Wanted 1/4" brass angle 36" length

Good suggestion, Trainman!
I have used Onlinemetals extensively during the past 25 years.
Of course, living 1 mile from them helped!
Now, living distant, I still find their selection and service to be excellent.
'Just received an order from them last week, 24 hours after I ordered it!

Re: 3/4" Scale J1e

It's your locomotive model, and your artwork. Do as you please! When we restored the #91 Heisler at the Mt. Rainier Scenic RR in 1980, we installed a stainless steel jacket for longevity. We also chose to keep it SS, and not painted. Some people complained, but we just invited them to paint it. Sile...

Re: "Catherine", a USA "Sweet Pea" engine build

Good Progress to see. My manufacturing habits for painting are to disassemble a finished portion (where mechanically natural) and clean and paint those parts. (The frame was first) 2-8-2 frame 002.jpg When reassembled, I move on to the next set of parts to fabricate, fit, and then paint. 2-8-2 Frame...

Re: 3c draw tube stop

A quick Google search reveals that Sherline has 3C Collet stops, along with other suppliers.
Hopefully that is the same thing as a "draw tube stop."

Re: steam locomotive emulator

A thought: The throttle primarily effects the cylinder VALVE CHAMBER pressure. The cylinder pressure is secondarily effected when the valve admits/exhausts steam to/from the cylinder for a portion of the stroke, which also varies the pressure. An interesting project. Are you assuming a "perfect" fir...
