David,
are you familiar with the "push-pull" method of stringing a bow? If so do that just a little bit to test for relative power. You can put it on the long string now....but be real careful that you do 2 things and I do mean watch BOTH of 'em.....Pull just enough to see if both limbs look like they are pretty even.....
if they are not then stop and make them more even.....when they are then put your scale on and pull it to 40 pounds and see where you hit that weight....if it hits 40 at about say 8-10 inches you are still heavy but close enough to go to your scraper......
When I say long string I define that as JUST as long as the bow (not real sloppy) I know it's the "exciting time" right now because you want to see her bend.....please dont do that you only have to pull it one time a little to far and ya got a kids bow EVERYTIME.
Here is your mantra.....are they even? where do they hit 40, are the even, where do they hit 40......keep that up till you are about 6 inches short of full draw.....then are they even, where does it hit 50 ....are they even and where do they hit 50....until you are there.
Make sure the limbs are real close to bending the same first, then pull and NEVER go past intended draw weight........the more bows you make the more the urge to just pull her back is gonna creep in.....stick to the mantra. Also, once you are back to about 6-8 inches of draw then be sure to shorten your string to "low brace" before you carry on......at about 14" you should be able to safely brace it.
Each and every time you shorten that string you better be damned sure you have nice even bends in the limbs....if not then get 'em even FIRST.. I'm not trying to be a smart ass....it just that there is a certain process to tillering, if you follow the mantra you wont have any big problems.....when ya get over confident (like I still do at times) something will come back to bite you and ya got either a kids bow or a broken bow.
Oh ya......quit forgettin the pics man cause you know us hill-billy's like our pics
