I am repairing a vintage audio turntable (a Thorens TD-124 for those of you who are audio buffs.). In order to do this, I need to be able to route perfect circles from about 1 inch in diameter to about 12 inches in diameter in 3/4 MDF.
I am thinking there must be some sort of precision router jig available for this purpose. If not, what kinds of jigs might I make and how best to make them?
Essentially, I need to route/cut the MDF into a perfect circle ca. 12” in diameter. Then I need to route two depressions in it, both perfectly centered, one about 1.5 inches in diameter around the center and the other about 1/8 width about 6 inches from the center.
