i am using a small die grinder now to cut the tear drops but the problem is i cant get the "perfect" when i free hand it. this is for my business not a hobby so i need to find a way to do about 4000 masks times about 8 holes/ mask in a safe, fast, percise way.
after studying this forum, i had a better understanding of routers/ jigs/ fixtures etc. what i am working on is i made a fixture out of fiberglass for the mask to sit on and a fixture that i will put on top. i am treating it as if i would be making an inlay, the only problem i have now is how much bigger do i make the outside of the shape to run the bushing along in order to make the tear drop the correct size?
i would post pics but i have no idea have to do that yet? if anyone can explain how to post pics i would be happy to take some pics to give everyone a better idea of what i am trying to do.
also, i am trimming fiberglass/ kevlar/ carbon, can anyone recommend a router which would be good for my application? how many hp? etc.
