Used to do a lot of bandsawing up north.
On more than one occasion, to save material and use up shorter bits (SHORTer bits) to short to clamp, I would end up tacking some longer lengths of the stock to the back of it, which worked well. Shimming can make all the difference in the world. Bandsawing cylindrical bits was always fun as when the clamp was tightened, the part would rise slightly. I would tap it down and re-tighten and that seemed to do the trick. Shimming makes for nice straight cuts at any angle.
What's fun is when you slide the clamp shut on the piece of 1 1/4" roundbar...and forget to tighten it.
