A simple coaster jig for 3.95" square coasters for batch runs on the F1
Inside the jig itself, there's a few small “O's that were cut out. You will use these on the screws that came on your L-shaped positioning piece to make your jig thick enough to use the stock screws (Unless you have thicker material and don't need them). Do be careful, because both the ”washers" and the screws tend to sprout legs and run off.
Please remember to always shut the lid for your safety and the safety of others!
