I love Rex Krueger’s videos, and I was thinking about his planing stop while cleaning up in the shop when i happened upon my collection of ‘dull and/or burnt reciprocating tool blades that I won’t throw away because who knows’ and it occured to me that these are the same shape, and rough size as a screwdown planing stop, while conveniently fitting over a dog, or using the existing holes to screw it down.
