I was having trouble cutting circles. They were tapered, looked like corks!!!!!!!!!!!! I followed suggestions from info I found here about slotting the screw holes on the bottom blade mount. Made a couple test cuts, didn't look to good. Then, the planets got lined-up, cutting like a champ...............
Now to keep the planets lined up..............
Thanks to everyone here...........

Have a great day!!!!!!!!!!!!!!!!!!!!!
