Andy, the guy for whom I'd shortened the bow collected it this morning and was very pleased with it, we had a quick try out and he could feel the extra draw weight. We also shot the Chinese repeater and another couple of bows.
I've done some more heat work on the tricky Yew stave and it's beginning to look more like a bow, it's been a bit of a pain, but it will hopefully be a handsome bow eventually. Here's a pic of it at about 65# at 24" so it's coming along.
I took some video to show what I'd done:- https://youtu.be/8-Fk_YIYew4
The deflex dip just right of the grip makes it look weak there and the left limb is stiffer than it appears, as it has some natural deflex near the tip. There's a bit of a kink 2/3 of the way along the righ limb... other than that it's ramrod straight ;-)
