Stabilizing a crack

[bfisher]

First, I would recommend replacing the limbs, but..........

I like the idea of using a small drill to stop the crack from spreading. Being old school how about one of those old limb reinforcing buttons that used to be used in the forks of a lot of bows? This would likely give the limb tips some torsional support.

Would you happen to have a photo of what you're refering to? I'd be a bit nervous drilling a hole, seems that would encourge the piece to break off.

No pic, but what I'm saying is that you can find the end of the split. It has to spread longitudinally down the limb. At the end of the split you drill a small hole which should keep it from continuing farther down the limb. If it doesn't then the limb was going to be scrap at some point in time anyway.

My concern is that with a crack like that the vibration from shooting is going to make it crack/split futher. Like I said, maybe one of those old style buttons in the bottom of the fork would help.

And yet another thought.

If repairing the limb doesn't work out, I know Dave Barnsdale from www.barnsdalearchery.com will make you custom limbs for $150. Dave has an excellent reputation for making a great product.

There are "super glue" type wicking glues available. At least one used to be marketed by Loctite. With a thin bead placed over the crack, they actually wick down into the crack and bond it back together. Since that portion of the limbs flexes very little they may work at least for awhile.

Obviously you know the long term fix.

Best of luck!

Super glue does crack in cold weather! Super glue becomes brittle in long term use and in cold.

If you add up the time you've spent pondering this and payed yerself - you would be halfway to a set of Barnsdales...

LOL, more like 3/4 into a 2nd set, I've been mulling this over for a while. I took gibson 787's advise and found this resin at 3Rivers.com. Think it will work?

Did you ask them if it's as suitable to use with glass as it is for wood? I found that the resins that come in 2 parts are generally the strongest. Also did you explain to them what your project is, they're known to be really helpful with their customers, I can vouch for that.
