Hi: I would check with Skil, if theydon't have bushings for it they may offer an adaptor to use PC bushings, which are readilly available. They may offer a new base plate with a 1 3/16ths hole which also would fit PC bushings. You could also check with Oak-Park, to see if the offer a base tofit that router, but then you would have to get bushings from them since they use a larger size than PC.
