Woodenspoke Posted April 1, 2009 Report Share Posted April 1, 2009 Well today I had to use a template bit and cut out a body. Because this was a recreation of a fender bass I ordered a template. Of course they sent a template that was only smooth on one side which to me is the incorrect material. Oil hardened hardboard is the proper material which is hard and has two flat sides. To make a long story short I found the thickness very hard to deal with. Some of my older bits would not even work as the gap between the bearing and the cutter was almost 1/4". Even a new whiteside pattern bit had a 1/8" gap. Why should you care well this is why. So in order to make these patterns useful I used the 1/4" patterns to make make a 1/2" MDF pattern. I like MDF over plywood, I just think it makes a better cheaper pattern. I do harden the edges with a thin epoxy prior to use but I have done with out. Unless you spend big bucks on plywood the cheaper grades are not always solid in the core and you wind up filling the gaps. Anyway the bottom line is a 1/4" template has issues. You will most likely be unable to get the bearing centered on the pattern and have the gap between the router and bearing not leave a lip. As in the first illustration above. The larger the bearing the harder it will be to get it centered. Quote Link to comment Share on other sites More sharing options...
