OK the month is up(well two days short) so I braced it and started pulling a bit but now the string alignment is out. It was good to 20" before I sinewed, now the string comes off at 18" and the bow hops all over the shop. I'm guessing heat is out so how can I get it back into alignment?

Here's a few. Any more? Of what part of the bow? From what angle?

Manually torque it into line. You need to train it into line as you work the draw back. Install some deeply grooved bridges to hold the string centred while you do this.

Once i get it in line will regular use of the bow keep it that way. It seems to me that the pulling would tend to line everything up.I have a habit of bring wrong though. ;D

It should. I have a few bows that have sat for a couple of years and they needed re-training since they drifted back a bit. Regular use promotes straightness.

I'm getting it closer I think but every once in a while the string comes off. When you torque it do you twist it hard over and leave it for an hour or so or is it a little more subtle than that. I'm out to about 22" now. I've put bridges on but I wasn't sure where they should be so they are a little inboard of where the string leaves the bow at brace height.

Thanks, but it's going to be unusable if the string won't stay on :D

 You have to be pretty bold and it's best to try to twist through the whole length of the bow rather than trying to just tweak it in one spot. I usually grip one recurve between my feet and torque the other end while(carefully) sighting down the length of the bow.

 Make sure the string isn't slipping and keep your head clear though.

You might be surprised how little heat it takes to correct that and how well the sinew/glue will handle it. You have nothing to lose if the string wont stay on.

Best of 170 fps@10gpp. My fastest ever and I still have some weight to take off the recurves. It did register one of 312 fps but I think that was an error ;D ;D ;D

I did about twenty or so shots when I was chronying it and it worked great. Then it threw the string >:( >:(. I pulled it to 27"(about) and the string barely lifts off. If I pike it a bit making the recurves shorter do you think that will reduce the tendency to twist and throw the string or should I just keep looking for that sweet spot.
