OK, I got my router guide bushings and I am ready to make my templates. the router guide sticks out of the router almost a half inch? I got the plastic ones so that I could cut them off more easily if necessary. Question: what material do you make the template with? Half inch plywood seems kind of thick but would be easy to work with once made. Should I use a thinner template and cut off the guide or just go with the 1/2 inch plywood or MDF or whatever?
