Using a wedge friction-fit design, I made a different scratch stock which can handle both flat and curved surfaces. This tool is chatter-free because of the full support given to the cutter.

If you prefer to make a traditional scratch stock that requires the use of hardware, here’s an example:

Thanks for looking. I made mine out of an old handsaw blade. You can use an old bandsaw blade or card scraper (,310,41069 (0.8 to 1 mm thick)) or similar steel sheet.

Perhaps I’m missing something obvious, but what’s the purpose of the wedge in the back end of the tool?

Really nice, simple and beautiful tool.
Clever, and clever to add the back end for curves.
Best thoughts,

Simple always seems to work better. Nice design, nice work.

Thanks for all the remarks.

To felkadelic:

The front and the end are both rounded. There’s another cutter at the end to use on curved surfaces. The side cutter handles flat ones.

Nice looking tool, ChuckM. I too was confused about the rear wedge and how the tool could be used on curved surfaces. Thanks for the details. I beleive a shot from each side would have been… wordless! Thanks for sharing.
