Avery, I've repinned quite a few sets of the old underlevers and haven't had any particular problems. I didn't bother removing the old hide glue, as I found it useful in repositioning the flanges when I reglued them. I do small sections at a time, and use a spring clamp or C-clamp with a length of hardwood to distribute the clamping force over several flanges at a time, using hide glue. Allen Wright
