So I have a PC 7424 and it has the standard 5" counterweight that I can use with the Adams backing plate and Adams pads?
Well I also ordered this http://www.adamspolishes.com/p-430-adams-focus-4-polishing-pad-kit.aspx
it comes with the 4" backing plate but no 4" counterweight so what do I do? Is it ok to use like that on the PC if I didnt want to use it on a drill?
