I have used material that
had bolts and washers in it. The holes are 1-3/4” and I need to plug these holes. Cutting the exsisting holes with a router or drill bit is easy. How can I cut a plug accurately that is 2-1/2” in diameter and 1/2” thick? I can make the hole smaller (maybe 2-3/8” or 2-1/4”), but I want to cut out the defects around where the bolt holes are. The material is oak and there are about 200 holes to plug. I guess I could turn the plugs, but that sounds like a lot of work and not all that accurate.
