Actually been working on these in the last few days.  Tillered one, got a little happy with the rasp and only ended up with 48lb@28".  This is for an auction so I think it'll be a good weight.  Last night I chased a ring on the second blank, the guy this is for asked me to flip the tips a little so I set up a little caul for this.  I stuck each tip in, put a clamp on the other end and it was fun to heat the tip and watch the bow bend down as it became limber.  Ended up with about a 30 degree angle on the last 2.5", not quite as round of a bend as I hoped but they match.  I'll try to tiller it this evening, I'm going to leave the tips static.
Feels good to make shavings again.  I have a nice setup in the garage now, with the new bow bench and a good bright light above.
