To work properly, a scraper must be flexed a little when pushed or pulled across the wood. But, if you have a lot of scraping to do, flexing the steel will likely result in some dog-tired fingers. Not only that, the steel gets hot after a few minutes of continuous cutting, so your fingers start to sizzle like frankfurters on a backyard grill.
This little jig I made, though, makes scraping a lot easier. Its size may vary a bit depending upon the scraper you use and what feels most comfortable in your hands. I like mine about 2 inches longer than he scraper and about ¾ of an inch narrower. A screw and washer secure the scraper at each end, while T-nut and a thumbscrew serve to flex the scraper.
