I found if I use a small shop vac to pick out the chaff and waste from the cuts I can:
- Tell if I need to do another pass
- Re-position the material for the next cut much easier.
I make a lot of little holes for small screws in my work. If I try to re-position the work for the next cut the chaff from these screws catches in the honeycomb. By vacuuming them out I prevent them from blocking movement and catch those that didn’t quite cut all the way through.
I should note: I have a shop vac with a metal can not a plastic one and I empty the thing out before and after a cut. I don’t want the chaff to ignite inside the vac.
