I often make fences on my work surface by clamping down levels and squareslike so:
I only ever use my speed square to overlap another square because that is thick and its accuracy is rough enough that I'm not worried about it bending.
My question is am I risking damaging the accuracy of my squares and levels by clamping down the following:
- Triangule shaped speed squares
- Metal Carpenters squares
- Aluminum I-beam styly levels.
- Combination squares
- Machinist squares
I'm not concened about scratching the surfaces with the clamps, just making them less true.
