I use a belt sander on the excess glass limb tips and it can burn the tips if I leave it in one place too long..20years ago when I did construction work I would use a thin plywood blade (8 teeth per inch?) Installed Backwards when cutting vinyl siding, I was told the siding could shatter/break if blade wasnt backwards. I wonder if a good high tooth count carbide blade wouldwork? I am gonna continue to use the belt sander myself
