Some people seem to like the larger pads for lap grinds but I'm finding it hard to fit my 8" hard foam pad from left to right, particularly as I like to sand off the middle of the pad. 5" rubber discs aren't quite the go for me either as I still like to work off the middle of the pad. Which leaves just 2" and 3" rubber pads for pneumatic die grinders?
The 2" or 3" size sounds good to me but a few people have stated you need a compressor with a lot of grunt to be able to work one properly. Are there are other tools about the same size of a pneumatic die grinder that can be run off a wall socket and that will accept 2" or 3" rubber pads? Couldn't find anything I liked from Dremel. Any suggestions?
