Drawing under/over size templates

[kenneth_b]

Greetings:

Silly question. I have a full size template for the body I'm building, made out of 1/4 hardboard. However, I need to make an undersize version since I'm going to route it using a brass template guide in the base of my router. I went to a lot of trouble to get a body shape I like, how do I draw a new template exactly 1/8" smaller?

I tried using a compass, but it isn't very acurate.

Thanks for any tips.

Use a 1/2" bit with a 3/8" bearing to cut the body shape. dont use it for the pickups or neck pocket or they'll be too small
