anvil adjustment
I never actually measured the anvil setting tool I have but I would say it's about the same thickness as a quarter. the tool from bandit is punched out of flat sheet steel. If you want to get one from bandit call their service dept. ask for chuck (he might know the number off the top of his head.) he's been w/Bandit a very long time. Make sure the edge of your anvil is perfectly square as they get rounded as material is fed through the machine. The best way to visualize is to compare the disc/anvil set-up is to look at a pair of scissors as they are closing. Hope this helps.
