Re: Modified D-valve dimensions from print

I understand your explanation of what is going on, thank you so much. I understand the plate is held in position by the steam chest and it's screws. I was just curious about why steam going into one of the steam ports would not go sideways to the exhaust port, by traveling between the plate and the ...

Re: Modified D-valve dimensions from print

A potential problem with taper pins for alignment, is that, unless the holes for the pins are through holes, it would not be possible to remove the pins. I suppose you could drill and tap them, but, this makes it unnecessarily complicated. If you keep the clearance for the steam chest fasteners tigh...

Re: Modified D-valve dimensions from print

Although steam is pressing on the plate and slide valve, the steam port has steam at chest pressure that is very close to the exhaust port. It would only leak when the steam port is uncovered. Gasket sealer would minimize or eliminate leakage altogether. This would be the area I would be concerned a...

Re: Modified D-valve dimensions from print

Usually the thin port plate is simply sandwiched between the top of the cylinder surface and the valve chest. RN I understand it is "sandwiched". This tells me where it is attached, but, not how. The valve chest cannot be the only thing holding the plate to the cylinder block, that would only hold ...

Re: Modified D-valve dimensions from print

when I made my last two allen engines, I made a valve plate out of eighth inch thick stainless steel. I duplicated the valve dimensions according to the print. made the d valve to print specs. I milled out the ports on the cylinder block a bit in order for them to align up a bit better. sandwiched ...

Re: 3/4" pumps Van brocklin

The valve rods are pretty much blocked visually by the piston rods and cylinder spacers. You can sort of see them, but, they can be seen better if you put them on the side toward you. To me, the "back" of the pump is more interesting visually than the front". Not only can you see the actuating arms ...

Re: 3/4" pumps Van brocklin

Yes, the drawings are available. I believe the link is somewhere in this thread. Perhaps Bill could repost it here. Yes, if an actuating arm loosens, or, needs adjustment, this arrangement can make it a challenge to get to the set screw. This actually has already happened to me one time. I was able ...

Re: 3/4" pumps Van brocklin

I wanted to be able to watch the valve spindles and actuating arms! You also get to see the valve chest. Why hide the fun stuff??

Re: 3/4" pumps Van brocklin

Here's a video of the 3/4" pump I made from Bill's drawings. Steam and water cylinders are made from brass. The pistons and slide valves are made from phosphor bronze. Piston rods and valve rods are stainless steel. The pump is putting water into the boiler at 100 psi. All seals and piston rings are...

Re: WTB: 1" scale steam locomotive

Andrew, Wow, sounds like you are having fun! It has taken me nearly a year to really get the hang of operating my loco. Are you running at the Illinois Live Steamers track? Yes, these little steam locomotive are a blast to run. I now have mine pretty much finished. Just recently, I got my Van Brockl...
