Ok, this is just plain stupid, and I am pretty sure I am missing the forest for the trees here.
Cut out a pattern for a circle jig the other day so I could cut out a 20" circle out of plywood. simple jig made of 1/8 paneling I had laying around. I measured out 10" from the edge of the bit, drilled my center hole and started my circle. I made a very shallow pass to see how it was going. Nice clean circle, BUT it was 1/8 of an inch short! So 19 7/8" rather can 20" I re-measure my radius, and is was still 10"
OK, what did I do wrong? What did I forget to compensate for? This was kind of frustrating to have happen, I though I had it cold.
Has anyone done the same as me? I still haven't cut the circle yet, so all is not lost.
Anyone have a SIMPLE cutting jig like this?
Thanks for the advice.
