4" backing plate??

[wgasa84]

I picked up some 5" Hybrid Power Finish pads on BOGO and they need a 4" backing plate. I tried my 3" but the pads flex too much on such a small backing plate. Any suggestions for finding a 4" backing plate for a GG6? I have seen a few DA 3 1/2" backing plates, but no DA 4". I might have to do a 4" rotary backing plate with an adapter.

Thanks!

I know there is a 4" rotary backing plate. You can get an adapter. I think that pad was kind of designed for the 3401 and their 4" backing plate.

Most 5" backing plates are just under 5" (4 7/8").

I tried my 5" bp... No dice

Dave is right about the 4" bp for the 3401. You might be better off with 5" pads as they are a standard size.

I might try the rotary BP with an adapter. I have a good number of those pads.

I don't blame you if you have a lot of pads. I just don't trust those adapters.

Red Locktite at the BP/adapter! If it comes loose after that, I'm doing something wrong.

It's not that, it's the 3/16" shaft.

I use this 3.5 BP" with 4" pads. Works fine.
