Do any of you know of a source for circular saw blades that have a
recessed center (to place the arbor nut below the plane of the blade,
as with most cutting discs on a 4" grinder)?
On a lark I modified a cheap CS to work as a jamb saw, and with a
bushing and a thin nut I can get to within 1/4" of the cut, but I'd
like it to be a true flush cut if possible, and the only way I see
that happening is with a recessed blade.
