I need to fasten a 1/4 MDF template to a piece of walnut in order to route an in-lay. I have routed many templates, but I will not be able to use clamps on this one, it has to sit flush and flat on the routed surface, the router sitting on the template. I was thinking about using double sided tape to hold the template in place, but not sure that's enough.
So, assuming you wanted to do something like this, how would you do it?
