A guy I know that cuts and sell smoking woods in a large way was using a miter saw the last time I was there but I tried it at home and had lots of problems. If the wood rocks or moves just a bit it can throw it hard before you know what hit you. I though I broke my hand and fingers once and have never used a miter saw again, a sliding miter may work better.
Now I use my table saw, of course I have to use round limbs about 3 or 4 inches dia or splits about that size. If it is a large log I use my chainsaw, cut sections again about 3 or 4 inches deep and then take those to my table saw and cut that up like a pie into wedges.
