Had some real trouble sanding some cherry today. The 1/4 sheet PC
seemed to be leaving massive swirl marks, so I swtiched to the 1/2
sheet (PC505H) and I'll be damned if I didn't get the same thing.
What I ended up doing was letting the machine get fully up to speed
before putting it on the work surface, and taking it off before
releasing the trigger. I also don't put any pressure on it at all -
just the weight of the tool. Lastly, I became very careful about
where I set the sander when not in use, as maybe it was picking up
pieces of grit from the bench or something.
Is this pretty much SOP for you veterans out there? Any other ideas
as to what may have been causing the swirls?
Lastly, anyone use the Grizzly electric palm sander? $16 a piece
seems awfully *cheap*
