Re: Boiler Dry Pipes Question

Morning, I am assuming you are talking about the two hollow stays that run from the back to front, yes you will want to seal them up. drawing air through those will do nothing good. I used something as simple as cork plugs on the back head. 1-19-03_06.JPG since i have moved to a smoke box throttle o...

The company probably went with a lower bidder for the machined parts.
Bean counters at work.

Re: Quieting noisy gears

I have a PM Research #3 (little 1/2" bore horizontal engine) that I've fitted with a centrifugal governor. The governor is like the photo below, it came premade from Microcosm Engine. It works beautifully, but the gears on the governor are ridiculously noisy. I've tried using washers to shim the ge...

Re: Quieting noisy gears

is the finish on the gears sharp? another words. do they need to be broken in? if so, i would be incline to run something like tooth paste in the gear set for a while to break them in, disassembly for a complete cleaning and run it

Re: 12VCompressor for a Brake Car

What's the piston diameter of the air cylinder? With that, the rest can be calculated out. :) Have you played with "jetting" the dump pipe to smoothen up the brake application? well that is different, depending if the car is a show car or intended to be a butt hauler. my show cars run a single .75 ...

Re: 12VCompressor for a Brake Car

Any idea what kind of spring pressures/rates to begin with? Not sure if It will be all that relevant because of my odd 2" scale and wheel sizes being larger, but I don't have a clue where to begin. this will be trail and error. that said, john likes to run 45 psi, so his springs are set where the a...

Re: 12VCompressor for a Brake Car

NP317 and cbrew, I've actually engineered my brakes to be spring loaded "on", and the brake valves are venting versions that dump the air pressure downstream to stop. I've also drawn up a notched linkage that I can have laser cut that will allow me to quickly adjust the amount of leverage the sprin...

Re: 12VCompressor for a Brake Car

NP317, don't the compressors spin full time similar to that of a bus or truck with air brakes? I'm not wanting a "silent" compressor, but when I've used mine to inflate the kids stuff you have to yell over it and I'd like to not have to yell at people riding on my train. Like cbrew, my brakes are s...
