Hope all the big truck lovers are doing well out there. Cup of coffee in hand I'm looking for a good solution to something...
I'm putting air horns and rear helper bags on my '30 Chevy 1.5 ton. I picked up an old brass compression gauge unit (200 PSI, dump valve, 27 pitch threads) that I want to use because of both looks and functionality, utilizing the dump valve for releasing air in the rear bags when desired. The challenge is that I want to separate the unit, using the 200 PSI gauge to monitor system pressure (27 pitch threads to either 1/4 or 3/8" compression) and putting the 27 pitch brass body portion with a 1949 50 PSI gauge that has 1/4" pipe threads.
Murphy's Law strikes again that I'd find something cool with an odd duck thread pitch.... On initial tries I can't seem to find conversion pieces to mate the old threads with the more modern ones. I found that 3/8" male compression threads would go just a couple turns into the brass 27 pitch body. Dimension wise, the 1/4" tapered pipe threads will fit mostly down in the brass opening. I've thought about using epoxy- basically rigging it- but would really like legit conversion pieces to blend the old with the new.
Any ideas how I can have my cake and eat it too?
Thanks
