If you have been reading posts here you will have heard a lot about this subject. A lot of you maybe thinking about trying a project but they all look to hard. And then there is that trying to figure out what bit and what template guide to use…….. “Now I made the pattern a ¼” larger so I’ll pick out the…… Oh to heck with it let’s see what on TV”.



The following might help with some of those decisions. In attachment 1 you see a cut away sub-base with labels. Those labels are important; they will help you with the table that is attachment 2.



This table is for the set of template guides we can call “oak-park”. (If you have a set that might be called “PC” let me know and I'll post a table I personal use.) The first column has the OD or outside diameter of the template guide. The second column is the maximum bit size for that guide. Looking at the rows under “BITS” for the size of bit. Below that is “C” or the distance between where the template guide meets the template and the router cut.



Let’s try one:



The ½” guide and ¼” bit. Locate the guide size then go across until you are under the ¼” bit. That box contains 1/8”, see attachment 3.



The 1” guide and ¼” bit. This time the box contains 3/8” see attachment 4



One more time, 1” guide and ½” bit. The box says ¼” see attachment 5



(If anyone spot an error in the table please mail me right away so I can fix it.)

Hope this helps,
