possible fix for set?
« on: October 11, 2012, 09:02:42 pm »
Maybe this has been discussed or done before, if it has, I missed it......just a theory. :) I was thinking that if you have a bow with set you could flatten the belly (has to be darn flat) reflex the bow, and add a belly lam. I am thinking that being glued in reflex, the belly would have to come past the nuetral plane (fighting the glue line) which would repair the string follow??? A form of PERRY on the belly?? This would be a extreme amount of work, but if you were short on wood, maybe it would save a bow?

Seems like that would work. Obviously one would have to retiller the bow. You got a bow to give it a test run on? I'm steam bending some reflex into a short osage bow right now. Ended up with about 2.5" of set, but it shoots great. Let us know how it goes.

Been done many times.  Makes sense to remove enough depth to remove all or most of the crushed cells.
 Marc posted a sinew backed bow which I believe was made of cherry that he had removed the belly and replaced it with Osage.

Yes it will work.With a person being short on wood.All depends on what a person thinks is a lot of work.Adding poudage...then trapping and side tillering to your draw weight again.Gotta have enough width to begin with to do this though.
It's a good tool to have in your bag of ideas.
Everybody has found the heat treating method of the belly to get rid of string follow though which does'nt take as long and less work,but heating it over and over and over is'nt a good thing either IMHO.It can dry the wood out to lose it's integrity if done too much.

Thats an interesting idea. I love 'fixing' bows.

I can't tell you how many times I've taken a bow too far, knowingly, to see where the limit is and so I could fix it. Lately they have been un-fixable...
I may try this one of these days but with horn instead...

Now that I think about it, a couple of times, Ive fixed a hinge with a similar method . I rasped and scraped several inches flat, pulled it to where I wanted, then added a belly lam and a thread wrap. John Strunk taught me that, if he says it works, I'm inclined to believe him.

I have never done a whole bow though...

Here is a pic of a hickory backed hard maple molle bow I made that developed some crysals. I added some osage belly lams that took out some set and added back a little poundage, as well.






Thanks to ole Pearl Drums for the idea. From what I understand, he has done this multiple times. Maybe he will chime in with more feedback.

Yup, multiple times Bulldog. I have used Ipe and osage and both woods worked great.

You bet.Way to go.It'll work.Enjoy it.Done it myself too a number of times mostly with horn though.Something I keep in the back of my mind all the time with this is that you usually will lose half of the reflex you induce after shooting.So you have to compensate for this most times.

I have at least a few times man. I think the last time was an ash bow from this past summer.

Add a bunch of glued in reflex at the same time. The slat will hold it pretty good.

I've done the same with a few bows and also used osage and ipe, two very good compression woods.
