had trouble with my first spinner. would crack rivet no matter what I did or how I operated spinner.
since this was my first go at forming rivets.... couldn't figure out why all my rivets were cracking. tried new side straps and new anvil.... exact same results.... cracks on new rivet, which were too large to run.
drove me nuts... after studying spinner. came to conclusion rear tail stock was too loose. as you turned handle to tighten down rivet against anvil. rivet would wiggle all over the place because threads were too sloppy. this resulted in cracked rivets.
ended up purchasing a GB brand spinner. tailstock threads were very tight. spun like a champ! good rivets each and every time.
