Porter Cable plunge router off center
Any help on this issue would be GREATLY appreciated. I am using a Porter Cable router that uses the interchangeable fixed/plunge bases... the plunge base is 6931.
When I use the fixed base, everything is fine. But, when I use the plung base, the bit is off center by about .020+. If I use a 5/8 bit with a 3/4 bushing, there should be about .020- gap between the bit and the bushing... but it rubs. I turned the subbase, but it rubs in the same direction, so I know the bit is off center. I called Porter Cable's technical product helpline. The guy told me "the plunge router base isn't made to be on center when using with a bushing." Then he told me he'd send me some special 'adjustable' base to use instead.
Has anyone else had a similar situation or experience and, if so, how did you resolve it? I think this is a load of dog doo, but don't know what to do about it.
