Ido remember you telling us about your health condition.

Yes, a vise is a good thing to have. Many things I do I would not be able to do without it.

You could possibly use a C-clamp or one of those clamps folks use to hold wood parts to be glued together. Sold in Lowes. You could use it with the edge of your workbench. Also, I know from experience, sawing off short things without clamping could result in an injury to the hand holding the part even for those who do not have any heath problems. I try to avoid it (my hands shake also, even though the reason is different...no, no, not the one that you folks might think of because I am from Russia).
I do have vise. Actually, vises. (yes I know what it sounds like). Two of them. One was bought 9 years ago, and one is from my childhood, given to me by my grampa when I was...10? I found it in my dad's garage in FL (how did I manage t bring it over from the USSR) and brought it home where it belongs, together with the screwdriver (also from when I was 10).

But I digress...get something to hold things for you. It helps with many things, not just sawing.
