Recently mysterious scratches were appearing at random on some of the timber I had cut on the table saw - a real pain as I could not find any cause. I examined the table top in microscopic detail looking for a burr etc - nothing. Then I found the cause - rust pits etc on the cheapo roller stands. Not really a problem when going straight over but when going over at an angle or slid then the problem surfaced. I was aware of their limitations when I bought the 2 of them at approx $50 for the pair but my budget didn't stretch to the $400+ for the "real" ones.
Solved the problem by wire wheeling the rust off, cladding the rollers in flat fold irrigation pipe [ to bring the 47.5mm roller up in diameter to make for a firmish slide fit for the PVC pipe], I also beefed up the horizontal plate which holds the rollers with 3mm aluminium tread plate.
I figure if I had the problem others might also.

Bob
