So, I did some searching and found several posts discussing sandpaper life. The gist of them was- sandpaper is cheaper than labor- use a lot of it. And I’ve applied this advice already.
I’d like to get a little bit more technique behind this and hope you guys can help. My questions are two:
1) How can I (as a newbie) tell when the paper is ready to be switched out? Surely one does not go until it stops making dust… do they?
2) What can you do to make the paper last longer? I ordered several 10yard rolls of Porter Cable paper off Amazon and am super happy with it compared to the sheets I was getting at Lowes. (mostly from a usability standpoint- sticky back, easy to cut, comes in a big roll…) However, it sure doesn’t seem to last long. I keep remembering or imagining hearing that a little bit of padding under the paper extends the life. Is this so? If so, how much padding?
The project I’ve been working on is a set of blocks- big ol’ alphabet blocks. I cut 4×4x2 pieces out of 2×4s, rounded the edges, engraved letters on the face and sides, and set about making smooth. The week leading up to buying my new sander I would put a strip of the PC paper on a length of plywood and run the blocks back and forth. That worked pretty well- but I could only get a couple of blocks before it really seemed that the performance had one south.
To make the super rounded edges I want I’ve been sticking the paper to sponges and camping pads. It seems like that helps the paper curve very organically around the edges of the block- but it sure seems to die fast this way too.
