Does anyone else get what I call "jagging" when using their ETS 150 sander?
Mine is a 3mm stroke, but I suspect that the stroke has nothing to do with it, and that it has everything to do with the abrasives that are being used.
What I mean by jagging is that the sander pushes and pulls away from the direction in which I'm sanding. It's a bit like trying to pull the sander through a field of rare earth magnets. It causes the sander to miss spots and sometimes can be quite a large deviation - yesterday I had a couple of occurrences sanding a 4½" wide board where the sander suddenly went in an arc that missed 2" of the width of the board. It doesn't happen every now and then - it's quite constant but to constantly varying degrees.
I only notice this with 17 hole discs, and have found that one brand does this more than one other brand, and yet another brand of paper does it far less. When I'm using papers that are covered in micro-holes it's a smooth as silk with no jagging whatsoever (thus indicating that there is clearly nothing wrong with the sander itself). It's also as smooth as silk when I'm using abrasives with no holes at all (like Platin 2).
I find this jagging adds considerable fatigue during a long sanding session due to constantly fighting to keep the sander on track.
