Pssst. Use baler belts.
DarkSyd,
sorry about that.
If you place an order, write GONGBELTS in the 'Notes' section on checkout; I'll give you some for free - enough for whatever gongs you order plus some spares.
I stopped selling them because bigger calibers and closer distances stretch the holes, eventually rendering them useless. I'm switching to fire hose, but I haven't completed the testing. So far, fire hose is way stronger and less stretchy than the seat belt fabric used in GongBelts.
Thanks!
Glenn
