Apologies for the poor lighting. This is my "decommissioned" bench in the corner of the workshop I resign to messy tasks I don't want to contaminate my work - like cutting metal. The lighting works well for tasks, not so much for pictures

I start by slipping the scraper into the kerf in the block of wood. I've found the vise jaws either can't get a good enough grip on something this thin, or cause it to bow a bit. Another advantage here is I only have to loosen the vise a tiny bit to slide the scraper out to do the other side
