Every time I see pictures of resawing wood and people reaching for a push stick and trying to run the last bit of wood through the blade I cringe. One of the best things I have done is to make a sliding fence that runs against the real fence. It has an end block with a replaceable back-stop piece since the blade runs into it a bit as it exits the piece being cut. You never have to reach for a push stick, you never have to rearrange your hands in the middle of a cut, and your fingers are well out of reach of the blade at all times.
I cut a lot of wood from billets from tress I have cut with a chain saw. The other big advantage of this sliding fence is that the fence-side of the wood need not be jointed. One just holds the block against the sliding fence, and since the fence is sliding, not the wood, one cuts a very straight line. Also eliminates the need to re-joint the fence side (and waste wood) between cuts when cutting veneers on the 'inside' of the block. I have cut a lot of veneer wood with this setup and it is the best thing I have thought up, both from a functionality and more importantly safety standpoint.
