Title: Recurve tip alignment help request
Post by: Mesophilic on April 28, 2019, 11:11:42 am: Closest I've finally come to a recurved selfbow but having a tip alignment issue on one end. My goal is 50# draw and static tips. I haven't put it on a scale yet but estimating 15 to 20 pounds over target weight, so still needs a bunch of tiller work.

What would you gentlemen suggest to correct the alignment? Thanks a bunch.

You will have to go over a bit more than needed because it will spring back some when unclamped.. Also you have enough "meat" in the width of the tips to reduce one side to bring it over a little if the heat adjustment isn't enough or to just tweak it a bit more.

Put it back on the bending form with the very tip clamped well, reheat the recurve area(or where the misalignment is) and pull it just past straight and clamp it in position then wait til tomorrow to unclamp it.

Grab hold, one hand on the recurve and the other on the tip and twist in the desired direction. Hold the string with the recurve hand to keep it from rolling off. Give it some healthy twists and see if it holds. I've done it on a few bows. Marc St Louis tip I believe, unless it was PatM. Sorry.

Probably both of us. Certainly for that amount of twist it looks like a quick manual torqueing will bring it in line.

For heating and putting bavk in the caul, if I use the first picture for reference, I would want to move the handle a little more to the left? Being that it will sit in the caul roughly how it's showing in pic one?
