Title: Different ways to save Compression Fractures
Post by: RT on November 14, 2007, 10:46:00 PM
Hi , I would like to get some idea how a wood bowyer would save compression fracture?

Believe the most common way is to remove the core wood and replace it with another.

I am very interesting what different methods of "patching" there are out there to save the limb.

Thanks in advance!

You can treat it like a hinge and tiller your bow to a much lighter weight.

I usually consider them fatal and make another bow.  Call it a penance for doing whatever caused it.

Bowyers, any one have any experience to share on the Patch?

I've used the Torges patch and it worked...all other methods I've tried ended in catastrophic failure...he has an article on it at bowyersedge.com....I used it on a BBO, not a selfbow but I assume it would work for a selfbow.

Go with Deans method, works on both self and BBO's

When using boo for bellies you should heat temper it first. Boo is very strong in tension strength but not so strong in compression. By tempering it first, you increase the compression strength.
  Those frets look pretty bad. What I would do is grind off most or all of the belly and reapply either a tempered boo belly or another compression strong belly wood.     Pat
