Re: Piston Ring Question

Is there another type of non-ferrous ring/seal that is suitable for piston valves using with bronze valve bushings? I can make and fit cast iron if that's the best option, but I would prefer something that wouldn't rust.

Re: Piston Ring Question

If you are using superheated steam into the piston valves
Saturated steam and bronze cylinder and valve cylinder liners.

Re: Piston Ring Question

Turns out it was Hercules Sealing Products, PS1600 series of hydraulic seals.
Thanks. I ordered a couple for my pistons.

Does anyone know if these will work for piston valves?

Re: Argent Lumber 3 spot

I wonder if you could roll and weld a cylinder and form the center section on an English wheel? I've also seen a plannishing hammer used for forming sheet metal between two surfaces. I've never used either but have seen videos.

Re: Argent Lumber 3 spot

Rudd - I agree that the hatched sections on the drawing look to be cast, with the unhatched sheet metal.
This one is 56" diameter or 11.2" at 1/5 scale? Comparing it to the track gauge, the Argent 3 looks to be closer to be around 40 inches?

Re: Argent Lumber 3 spot

If you used resin or sodium silicate sand you could make a disposable core box on a 3D printer. Because you don't need to ram these types of cores the walls could be fairly thin, like a vase. To remove, use a disk grinder.

Re: Argent Lumber 3 spot

I can think of a couple of ways that you could make the stack as a casting. What is it, about 8" diameter?

Re: Could I get tips on dumpster diving for materials for your build?

Side rods from aluminum? Sure. but it's a trade off. Easier to machine and less reciprocating weight, but more likely to be scratched or bent in the inevitable major derailment and is doesn't retain paint as well. I used a piece of aluminum bar for my American and it works fine (except for the funny...

Re: Could I get tips on dumpster diving for materials for your build?

A file and a magnet will help a bit to tell if something is suitable. If you can cut it a piece of steal easily with a file, it's not hardened. If a magnet sticks to a piece of brass looking stuff, it's not brass. If the you take the file to brass looking stuff that the magnet doesn't stick to and t...

Re: USPS is a mess...

GWRdriver, it may be true. I can't speak about bricks, but for groceries there is a system, I think it's called "bypass mail." My understanding is that the groceries, etc., aren't physically processed through the post office. They are delivered on a pallet to the airport and moved as if they were ma...
