 Routing small holes
Terry firstly I do not see the need for the holes to be produced to suit the degree of accuracy.
Here is my interpretation on how I would go about solving the problem.
First decide on how large the hole is to be inserted. Then decide on what cutter and template guide you are to use.
Simply add the diameter of the hole required to the difference between the guide and cutter and produce a circular cut-out in say a square template with the circle cutting jig.
As an example in Metric
Size of hole required= 39mm
Using a 40mm template guide with a 10mm cutter
Therefore size of hole in template is 39mm + {40mm-10mm} = 69mm
Should you change the size of the chips you will require a new template with a different cut-out.
Terry I hope this has been of some help, unfortunately I will be away for the next 10 days but I am sure my star student Harrysin will be able to assist you with any further questions.
