Block to cut R-Patches from tubing straight. For 6mm ID and 8/9mm OD tubing. This is a new version, different from the other 2. It's easier to print as it does not have thin tabs.
All you need to complete this set is a 6mm rod. A 6mm drill bit works well. You insert the 6mm rod into the tubing, and hold it on the block and cut straight along the tube (pitctures available as soon as possible)
In this set you have 4 different sizes for different widht barrel windows. You have cuts for 4mm, 5.15mm, 5.4mm and 5.8mm. All you have to do is change the plates accordingly. Use the one that is the closest widht to your barrel window.
Best printed in Polished Plastic as to not leave any powder residue on the patch.
