tip overlay falure... Please help. I'm at a loss...

[brian_restivo]

I have to use something for nocks. Tips are too narrow to notch. I could use a wrapped nock, but that would look a little out of place on this one. I'm probably gunna switch glues and go back to studding them. I'll have to keep it marked out better so I don't hit one again. Tho im not to fond of metal in my bows.

I had a failure once with 5-min epox, came off in the shaping process.
Use superglue most of the time now, would give TB3 a chance, too, if it was wood, but not for horn overlays.

I've put a bunch of overlays on with two-ton epoxy over the years and never had one come off. I never scored it with a hacksaw blade, though. I don't trust five-minute epoxy too far. The only overlay I ever had come off was purpleheart overlay on ipe glued with TBIII. The string broke on the bow at full draw, and it vibrated hard enough to crack and craze the finish all over the bow. About a month later, one of the overlays popped loose.
Cacatch, the main reason people use overlays isn't to protect the wood in most cases, it's to allow you to build skinny little tips that increase th bow's speed and performance.

As in this case...   I was trying to get some pics up with my new camera but the pics where to big and I'm done screw'n with it for today. I just ordered some kwick-it blue from 3rivers. They said thats what the use on there tomahawks so I've got my hopes up for it. I'll post how well it works in a week or 2.

[Cacatch]

Yeah I know. What I was getting at though is that unless the wood is very soft and likely to be damaged by the string, you don't absolutely HAVE TO use overlays, there is a simple solution which is not to use them, (i.e. don't make the tips so pencil thin). The first few bows I made I made with the pencil-thin idea in mind too, and quickly found out that I flat out didn't like overlays and started to wonder why I was even doing them. Just because so many other guys did and it seemed like the thing to do? I decided to go my own way and quit the overlay pencil-thin obsession. If a guy likes overlays and all that, great. I just meant to point out that there is another option too.

You do have a point. Tho i've been going in the opposite direction. My tips keep getting narrower. I've only finished 7 or 8 bows (and maybe twice that in "learning experences"). I started using wood overlays on white wood with no problems and moved on to  buffalo horn last year. I'm more drawn to the looks than anything else, that and trying different things.

[Jmilbrandt]

I have used titebond, super glue, two ton epoxy, and five minute epoxy. I have only ever had a tip come off with five minute epoxy I don't use it anymore.

Easiest solution would be to forget overlays on knocks. Unless maybe you're using a very soft wood, you don't really need them. I never put overlays on anything.

There's a lot of wisdom in these words.

[brian_restivo]

Yep...  I think we have a consensus here. Don't use 5 min epoxy. Hopefully someone is saved from running out of cuss words.

As Eric said, epoxies are too brittle and it's the shock that gets to them.  Unfortunately I have also found that superglues are much the same, they seem to be acceptable when used on horn though.  TB3 seems to work on everything.

Brian, I have had the same problem in the past. I now use smooth on Epoxy and heat to dry. Since you have sealed the wood from previous glue attempts, it will be hard to re-glue. I would soak a horn tip  in boiling water and super( glue as ryan) has said. Or make a tip with a split down the middle and splize on the tip with super glue. I have done the latter with success. Good Luck Denny

Looks like Im going to be trying out a couple of glues and turning my head as I shoot....  Just in case.  The guy I talked to at 3Rivers said Kwick-It is basically a super glue but for what ever reason takes the shock. 17 dollars for super glue, it better. I might rig up a test with scrap wood and some horn. Then drop increasing amounts of weights from it. That might give me a better idea of which glue to use.
