Good morning. Steel boiler with steel tubes.
Okay, my recommendations are strictly for copper boilers. Does not apply in your case.

Re: CliShay/Big Bertha question

I think the important thing, for cylinder drains to be effective, is that the piston does not ever cover the drain hole at either end of the cylinder, otherwise, the water cannot exit the drain cocks. If the drains are mechanical, you leave them open until only steam comes out.

Re: CliShay/Big Bertha question

We also are using the modeltec plans, going to follow advice from here and pour Bronze cylinders, so I can put the boss where needed. I can guess on locating the cocks for the bottom. But on the top...just above the piston at the bottom of the stroke? That simple? Wouldn't happen to have any photos...

Is this a steel or copper boiler?

I have been working on this for about three years. Pouring the coals to her now to have it done by early fall.
How does it stay on the rails when it's upside down?

Re: Kozo"s k 27

The photo looks like Goehner, if it is, that's 4-3/4" gauge track.

Re: Covid Creations

What gauge(s) is that? This will have 3.5" and 4.75". I might add a 4th rail to capture 2.5" gauge but I'm not sure if I want to deal with it. I have a 4-4-2 in 2.5" but I'm not sure if I'll go thru the ordeal of getting it ready to run. ~RM excellent!! (My gauge is 4-3/4") I'll be over soon!

Re: Air Pump D Valves

Bill, what gauge is that loco? How will the material for the port face be attached to the cylinder material?
Looks interesting!

Re: Air Pump D Valves

Hi Bill, that is exactly what I did on my Van Brocklin pump, but the reverse. Brass port face, (cylinder block) with phosphor bronze slide valves. So far, so good!

Re: Air Pump D Valves

Yes, glass filled anything will work just like sandpaper! 4301 Torlon does not absorb moisture and may be worth experimenting with for slide valves. It is impregnated with Teflon and graphite. As Bill has mentioned, it is not clear if any material other than metal for a slide valve will keep sharp c...
