| Post subject: | Sanding pad reconstruction |
You have to love urethane foams - the kind that self destruct over time. I've had that happen on a Makita planer I own and the sanding pads for my PC sanders. I ordered some new pads for my sanders, but decided to see if I could "rebuild" the old ones. I didn't want to do the "six million dollar man" thing to them, but if I could put something together relatively easily and cheaply it might be worth the effort. The first thing I did was remove the old foam and glue residue from the fiberglas backer. Then I cut some foam discs out of the floor mats we know and love. I used a large HF hole saw, and a smaller Vermont American hole saw to create the pad. It's not quite 5 inches - but close enough. I cut out the recess in the pad with a pocket knife to allow the reinforcement plate and rivets to recess into the pad. I glued the pad onto the backing with weldwood contact cement. I left one pad as a PSA type, on another one I glued an old mylar micron hookit disc to the face. Hookit is the opposite of hook and loop, so it effectively makes a hook and loop pad. I will glue a hook and loop disc to the last one to make a Hookit pad. 3 out of the 4 rebuilt pads worked O.K., but one made the sander run rough and noisy - maybe a balance thing. I'm happy enough with the results. |

THose floor mats might make GREAT sanding blocks! I'm using flip flops from the dollar store- they are not smooth (have little treads) but they work ok. I use the anti-fatigue mats, I'll have to check out a mat like the one you love.... |
