Scratch-stock


This double bead is done by means of a simple step-and-repeat using the basic single bead cutter.
This is the newest tool I've made for myself, a scratch-stock. It's made from oak, but just about any timber would do the job. I'd probably stick with a hardwood, just for durability.

Basically, it's just a holder for a shaped scraper. The scrapers can be shaped to produce beads, as shown here, or grooves for inlaying, or even complete mouldings. Usually a scratch-stock would be used for relatively small features, as the effort required to create the forms in the wood goes up greatly with the increase in the area of scraper in contact. In this case, the stock will take a maximum width of 35mm, and I doubt I'll ever get close to using that whole width.

I've made the scraper here out of a saw plate. I would have used an old plate, but I don't actually have one that's unusable as a saw and a pair of brand new throwaway saws only cost twelve bucks; they'll supply me with metal for scrapers and what-not for years. The steel is good and hard, but not so hard it can't be shaped with a file as long as you stay away from the edge with the hardened teeth.
