my bet is they use the claw to hold the riser while the band saw cuts it
[QUOTE=jksoft;34859]I’m certainly no expert in these mattters but it almost looks like they are trying to use the shear to bend and twist the riser at the spot they have made partial cuts in order to get to snap off.
I think BigMoose had it right earlier with his cutting out a wedge suggestion.[/QUOTE]
