This is a new product I have developed to insure proper support for my 9″ dia. shrinking discs.
Shrinking Disk Pad $20.00 * plus shipping
A proper mounting of my 9″ dia. shrinking disc should include a 3″ to 4″ dia. mount flange(standard equipment with most 7 and 9 inch autobody right angle grinders) then the 9″ Backing Pad, then the shrinking disc. The securing nut should be below flush so it won’t rub on the panel when using the disc
