Default Aster gas tank regulator valve

This is an old problem with a need for a new solution provider......As some of you may know the Aster gas tank valves were largely a full on and full off type of valve. I asked Norm Saley way back when to produce a more gradual angled gas valve to release the gas in a likewise manner. This valve enabled me to fire my engines a bit more easily than the ¨stand by and watch the hair come off my hand" firing method.


So, I have one of these valves on my Aster Greenbrier Shay but I need a few more for other gas fired Aster engines I reacquired (really need to stop doing that..). So, can some machinist out there please assist me in reproducing some of these? I can send the one I have to make it a bit easier to reproduce.


Yes, I have tried the usual folks. Norm has stopped making much and Jim does not seem to respond to email much either...I suppose in my retirement, I will need to learn how to do this myself....but until them...help, please...


Thank you,
Sam

When I recently had my South Bend in pieces to scrape the cross slide - I successfully slowed the taper on a couple of gas valve trims with a pillar drill and a fine file - then finished with 320 and 1000 emery.

Charles,
Do you have the valves or do you need me to send mine? I know you guys are super busy so I wasnt sure it was a viable option. Please let me know and cost to produce via my email.

Thanks,
Sam

Sam I have been making housings for my fine taper spindles. Can do a threaded or solder in housing. Outlet is usually a soldered pipe that I use. Can have a knob or wire handle. Here is a brake post tand I recently made

Jason--nice work. Thanks for the responses. I know there is perhaps not the demand for this part these days but anyone who has an Aster gas fired engine should look into getting that valve replaced along with the gas inlet value. TRS does supply those.

On my Aster S2/6 changed out the gas valve with a roundhouse gas valve works great.
