.25 cal regulator

<< < (2/6) > >>

Treb37:
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. 8)

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?

Motorhead:
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.

Treb37:
Yep...I understand the concept it just hadn't occurred to me that they would be different lengths. I looked at Haji's diagram and thought the shim stack was the same as mine but I see now that the ninja reg has one less washer.

Treb37:
Here's what I keep getting. On the initial fill it looks promising but then stops at around 1K output no matter how much pressure I add to the bottle. Then Degas and try again and it will only come up to 750-800psi. Frustrating as *(&^ I want to smash the reg with a sledge hammer.

In another unrelated note the bottle outlet valve is also a POS. It's metal on metal with no seal. I had to cut a disc of electrical tape and slide it onto the stopper to get it to quit leaking.

What's really strange is the regulator appeared to perform well before I took it apart. I was getting 900fps+ with JSB 25.39's so I know the pressure must have been at least 1900. Apparently it did not like being taken apart....

Motorhead:
Look at the seat on the end of spool. If it is heavily dented / damaged there is a big part of the problem.
