Fixing Chrysals?

You will get a load of different opinions about this but personally it spells the end of the bow for me.
Chrysals in one part of the limb only dictate that part has collapsed due to a hinge/ insufficient thickness compared to the area around it. Chrysals over the entire length of the limbs tends to say either the design is wrong for the draw-weight and wood type/bow design. Or the moisture content was too hight when the bow was being made.

There are ways to patch a localised chrysal by removing the affected area and replacing it with a new bit of wood but you also need to fix the reason it happened it will just happen again. In my mind this is reserved for small areas that have happened mainly due to wood defects rather than tiller problems.

There will be lots of people who will tell you their bow has chrysals and it has shot fine for years.

Personally I try to take the chrysal as a lesson learnt and move on to the next bow.

Just my opinion sorry if its not what you want to hear

I agree the only way to be rid of them is to burn and start with a new piece

Would a patch of rahter thick rawhide on the belly also help to restore compression strenght or has it to be wood?

I dont think so matey. We use wood because its great in compression, rawhide is not so.
Another bit of wood such as a belly lam but then you are just hiding the problem and if the belly cells are already crushed you are just carrying dead weight in the limbs,

Nope,  :)well maybe if it is one little spot but if it all over,then I will stick with nope.

Thanks for the replys everyone.  If my next bow survives tillering but has chrysals I will leave it alone as a wall hanger.SS

I agree with Dwardo but.....
Have a look on Dean Torges website for the only way to really fix a chrysalled section of limb. I could try to explain it all but he does a better job. 
Have a look - it's a great article.

The only way to fix them is to not get them in the first place. Check tiller frequently and only remove wood a little at a time. When working on a particular area go just a little beyond it and kind of feather in then wood removal. Once I string it I use only scraper like tools. No power tools. They remove wood too fast.

To fix a chrysal retiller by leaving it alone and remove wood from above and below it.

I've also had some fixes by gluing on a rawhide patch over it.

Those are all bandaids. Eventually the bow will fold on itself. Who knows how long it will take. Jawge

Yup, replace with wood, via the method described in detail by Dean Torges.
