Making router templates, how to achieve near perfect accuracy
Does anyone have any tips for doing this. For example i'd like to make a chopping board with some curved pieces which will all join together.
My first though is to print out the design onto paper, attach to mdf or plywood then cut round on a bandsaw. I can tolerate a small divergance from the design appearance, but of course the pieces need to fit together perfectly, and a bandsaw will remove material as it cuts creating a gap in the template.
I've looked around at finding a bandsaw blade with a very narrow blade, the smallest i can find is .35mm. Perhaps using this with an mdf or ply sheet would mean losing just .35mm material which would be acceptable when it comes to gluing everything up?
I suppose the other option is to use a laser or cnc service but i'd rather avoid doing that if i can.
