Need to ask for confirmation if I understand this correctly. Any help appreciated.
I plan to use a 3/4" bushing with a 1/2 in cutting size bit. The finished size routed rectangle I need is 1-3/4 x 3/8. The 3/8" size comes off the edge of the wood.
As I understand it, the math is as follows, 3/4" bushing - 1/2" bit = 1/4". So for the 1-3/4 length I need to be 2" long on the jig and the 3/8" size I need to be 1/2" since it is open to the edge on one side so I only need 1/2 of the 1/4" or 1/8"?
Is this correct?
Thanks.
Brian
