If you loosen the two bearing block mounting bolts, but leave them snug then turn the handwheel through several revoloutions so it can "find it's center" then tighten the bolts back up that slight binding can probably be eliminated.
I still don't get what hand scraping is, or why it's a good sign for a tool to have it? (I can see it as a corrective measure for something that was machined wrong.. but assuming it was machined correctly what does it do?)
