I wanted to up the pressure output and increase the bottle size on my .25 gauntlet so I ordered shims and pressure tester from Hajimoto. I removed the reg from the stock bottle and put it on a 22ci bottle from Ebay. The shim kit came with enough shims to also up the output of my HPA converted Ninja QB78 to 1400psi and that worked perfectly. When I tried shimming the Gauntlet reg I get all kinds of weird pressures none above 1950 and most often under 1K. Has anyone else had this non-Ninja regulator apart? I'm pretty sure I didn't lose any parts or install anything wrong but since it just won't work since I've had it apart I'm beginning to wonder.
Thanks Haji, would you have any ideas on why the same Belleville washer stack in the Ninja regulator produced at least 2400psi? I just tried what you suggested polishing them on a piece of glass then clean and lightly lube. Filled to 500 and degassed, all worked well. Filled to 1000 and it was working so I went to 1500 and the reg only got to 1200. Degassed and tried again filled to 2K and got 900 psi. There doesn't seem to be any rhyme or reason for how this thing works. I have a Ninja 4500 regulator coming and I hope I can adjust the shim stack in that one and make it work.
Look at the seat on the end of spool. If it is heavily dented / damaged there is a big part of the problem.
DOUBTFUL ... Regulators and there correct function while simple in basic operation can be screwed up with simple oversight on the basics of what required getting from HP to controlled LP.** See NO picture of the Spool ends seat
Guys ... The bevel stack just creates a given SPRING RATE. Pending how close or far away the actual seat is from end of spool dictates HOW FAR the given bevel springs must compress to get the seat to seal up. Closer this gap LOWER will be the set point ... Further away HIGHER will be the set point.Thus the WHY FOR a given spool and bevels in differing bodies have a different set point.
Well I guess I'm glad to know I'm not the only one having this issue. I'll keep trying and see what I can get done with what I have. I keep running my 90ci Benjamin bottle out without ever shooting a single round. Running to the next town over to get it filled at Scheels is getting old....I think I need a compressor. I overhauled my hand pump and I've been pumping like mad with that but only up to about 2K. I'm still recovering from a broken elbow from a bicycle wreck on Dec 5. I see you are sold out of regulators, Should I just see if I can get some better quality Belleville washers and experiment with them and if so where should I get them?
Thanks again Haji, I don't suppose you have one of those testers? I have a Pro V2 4500 psi reg on the way and wanted to confirm that I should be able to change shims and rupture discs to make it a 3K reg?
