Re: Future considerations from EE

I would like the Nathan top mount dual check valves. The N&W used these on a lot of their equipment. Pontiacguy1, You're right! But look, the more modern version of that Nathan double check valve, used by N&W was slightly different. The check valves for the Worthington 6SA feedwater pump (left) had...

Re: Nathan 1918A's are in Production

Hello Anthony,
Good to read your news regarding those superb injectors!
Looking forward to those Nathan 4000s, too 8) . Despite they will looking slightly oversized at my class A of scale 1 in 10, I think about having one.
Carry on!

Hello Jack,
What an achievement first to make that precise master (patern) to get a couple of perfect bronze castings :!:

Re: My N&W class A 1239 (gauge 5", 1 in 10 scale)

Hello friends of the N&W, Still alive I overcame this nasty year with some indoore jobs. The A project not finished yet, I prepared that engine for a first steam up with friends this yearr :D . Thus all the SuperScale globe valves which were leaking after some use were to be improved. I found stems ...

Re: Which steam pump would you build?

Bill: 100 % agree to what you wrote! Pontiacguy1, VGC : There are lots of smaller single piston pumps. At least one I saw on a scale gauge 1 narrow gauge locomotive - may be 1 / 24! Far the best such pumps are made by manufacturer Hans Link :!: . They are proven, very reliable and not expensive. You...

Re: Kunkle safety valves

Hello Bill, Thank you for your good and precise explanation of this subject! :) Regarding the question of boiler steaming capacity, I found this simple rule of thumb (in case it seems to difficult to make a life test): Locomotive boilers of usual construction can produce about their raw (empty) weig...

Re: Nathan D.V.7 Lubricator

Hello Chris, I wonder if you know the solution for my A? The casted housings were just of scale 1 ", but that was what I had. There are just two independent pump elements of 0.1 " dia by 1/8 " stroke :idea: Thus watchmakers accuray isn't necessary :) . The pistons are pressed in and drawn out just b...

Re: Water pressure gauge

Agree,
To smooth the pulsations of the piston pump and not to fatige the gauge, I recommend a choke (or long small dia water pipe) to the gauge :idea:
All the best
