My DA sander started wobbling mid job and I found the real problem was a $4 pad
Was blocking out a door on a 2016 F150 Tuesday and the sander started shaking so bad I thought the bearing was shot. Turned out the backing pad had a chunk missing and a new one for $4 fixed it in 10 minutes. Anybody else keep spare pads in the box or do you just run them till they blow apart?
