Bully disk


Premium User
.110 is getting to be close to the limit. I discard them when they are at .100 thick.
.145" Bully friction discs?

I find they work better the thinner they get, but that requires using thicker floater discs to get the air gap back right.
<.100" and you likely won't get the air gap right with the stick floater and no shims.

Air gap should be .030"- .050." Anything more than .050" will just tear stuff up and not work right.

?Thanks and God bless,
