Hello all,

Can anyone provide advice on using a smaller backing plate on a Rupes 21 - I have heard that a Rupes 15 backing plate can be used on the 21 but it requires a washer modification.

Appreciate any advice......

the rupes 15 backing plate fits on the rupes 21 machine. the washer mod is to increase the clearance of the backing plate from the machine, which gives you more speed and (theoretically) more cutting power.
