The Home Machinist!

Tom,
I did do some poking around after posting and found it on mcmaster.com for 9 bucks a quart.
Thanks again.

You know, I was thinking of that, so when i am ready i will give the local store a visit
Thanks again
Chris

i designed the attached pressure feeder to send oil to a sight glass which has a needle valve built in for control. i use this with 2 sight glasses for the cyl. luber on my Chloe but it would also work well for an air pump. the piston would get steam press. from the air pump supply line so it only works when the pump is running.

Rich, have you had any problem with hydraulic lock on pump when the governor shuts the pump down? I have also toying with what to do with the exhaust. I have concerns of routing the exhaust into the smokebox and into the exhaust stand due to amount of water from the steam condensation. Has anyone seen this issue or am I over paranoid. I am leaning towards just placing the exhaust line down and angled out at the pump. Any thoughts?

Most any pharmacy will have it. It's a primary ingredient in many hand lotions.

I would not worry about the condensation. I have my exhaust into the smokebox. Yes it does throw out a bit of water when you first startup but it never locks.
The best bit is the sound of the pump just ticking over when the loco is standing in the station,just keeping the air at the right pressure, really satisfying.
As I have just retubed the K36 I thought I'd share a pic of the refurbished smokebox - you can see the blower feed and the smaller exhaust feed to the manifold from the air pump. The whole setup is a bit crude but seems to work well.

Jeff,
Hydraulic lock? Never. In fact a pump can run on water. Slooowly.
Here's the secret on Westinghouse Pumps. Full size air pump systems and model air pumps too.
Reading the various treatises on Air Brakes there is a warning regarding a drain hole on the
Governor that must be kept clear to atmosphere. That is a leak !! See diagram "c".
Its primary purpose is for draining the air trapped under the air valve "b" to allow the steam
valve "26" to rise. A secondary function is when the air valve rises to shut the pump down
when the Main Res is up to pressure. Now there is a direct leak thru from the res.
This ensures the pump is cycled on to keep it hot. At the same time, if you look closely
at the diagram "f" there is a steam leak drilled thru the steam valve to also cycle the
pump slowly. On the miniature governor the "c" leak is just a scratch on the sealing surface!
For the steam leak, I added an adjustable stop (see the small valve wheel) to crack open
the governor just enough to keep the pump ticking over slowly.
Someday I'll find out what size hole that represents and drill the steam valve then plug
the adjuster.
Keeping the pump hot minimizes condensation and also keeps the water accumulation
blown out.
If the above is clear as mud, I'm doing good.

Imagination is your best tool.

Below are a couple of pictures of the air compressor I completed except for the cylinder drain valves. They just arrived from COLES today. I decided to wait to install them, they are 1/8" copper tubing which with my luck would get damaged multiple times before I finish the engine.
I tested the air pump today. I used a cylinder I had which was ~316 cubic inches for a test reservoir, the locomotive reservoir is ~260 cubic inches. The air compressor pumped the test reservoir up to greater than 80 psi in about 10 minutes. The pump ran great with no issues. In one picture I placed the compressor on the boiler mounts just see what it looked like. As soon as I get the mounts painted the compressor is ready to mount for last time and finish the plumbing. Hope everyone enjoys, Thanks for everyone's advice from the forum. Jeff

Who patterned that pump?

Its the closest to scale I have ever seen.

The castings for the pump are from Richard Ulin of Ulin Locomotive Works. He offers the castings as a non functioning pump, however they can be made to work. There were a few issues that had to delt with to make it work. That was a fun little project.
