Beeman R1 (HW80) strange ring noise in shot cycle??

[Bayman]

Could piston rod be clipping hole in cylinder end block, ie not quite straight ?

This would be my guess for the other gentleman's R1. I've experienced the same noise more than once when the spring guide base wasn't large enough to center the guide. The guide would go off center and even a straight centered latch rod would clip the side of the trigger block opening.

Does the gun have a piston sleeve?

No but it has a Vortek PG4 kit in it. That kit as a thin steel outer guide at the trigger end. I have a more conventional ARH kit that I could try again. I tried it shortly a few years ago and I don't remember if it still made the noise. It was removed because the gun didn't make as much power as the Vortek. I'll tear it down and have a second look in there and put it back together with the ARH kit. Hopefully the noise will go away and I'll find the missing power. I'll see if I can get a better measurement of the TP. I thought that synthetic sealed Weihrauchs were 3.2mm.

I'll be back with the results later

If you want a VMach spring done to the old venom 80 spec 28 coils and its OK to post to the states!! Then let me know. Regards Paul

I removed the Vortek kit, inspected the comp tube and piston seal for damage and installed an ARH spring kit with the OE piston liner. Test fired without a scope and the gun sounds normal now. Ten shot string of 5.53 FTTs, 735 fps ES 12 and SD 3. That's 17.58 fpe. That's about what I remember that kit doing last time.

Assuming the noise doesn't return I'd have to think the noise was from the Vortek steel outer guide resonance. I have to do some more testing with a scope on it.

Thanks all for the help

personally I find 17-18 FP the sweet spot for these... accurate and easy to shoot. Much more and accuracy (or maybe the ability to achieve it) seems to suffer.

Hi JB..I'd go 19 ft lbs as the sweet spot. Anything more is a little too much. Slight off thread but on FAC power levels I remember shooting a Webley Venom 97 running at 16.8 ft lbs it was unreal..a mild nudge in the shoulder like a legal limit rifle..it was .22 but really nice at that power level.

I'd invite you over to play with some of my "fac" springers, but the plane ticket will make it a little pricey - I've not shot them myself for a couple of years !

Thanks for the offer. I appreciate it. I'm out of the woods with this thing. I shot it a bunch today. The noise didn't return. It's a much more enjoyable gun now. Besides losing the annoying ping noise, it cocks and shoots smoother. I couldn't check if the accuracy changed as the winds were strong, gusting and from random directions.

As long as the gun is accurate, I'd be ok if this gun stays shooting this way.

Be well all.

Excellent stuff. Glad it's sorted. Enjoy.
