    I'm getting ready to compound my 290 for the first time and seems the only thing I can't wrap my mind around is how to effectively hit all the smaller areas with say something like a Dewalt DW849 polisher. Seems that most use at least a 7" polisher, but on my 290 all the flat surfaces above the rub rail are broken up into 3 - 6 inch tall sections. I was thinking of maybe trying to find a smaller polisher, maybe a 5". I know it would take longer for below rub rail, but I think it would make the job easier for above. Any advice?

    I have a 3" backing plate and 3" pads for my DA. Some spaces you just cant get into.

    I remember this struggle as well. I never came up with a really good solution except banging around with a standard sized machine.

    So you just get a separate smaller backing plate for something like a 7 inch polisher? Didn't realize that was possible, but sounds like it would work well.
