Title: Epoxy failure
Post by: Earl Jeff on December 19, 2009, 04:16:00 PM
I love the snow so I went stump shooting today in the Snow Storm and use some new arrow I just made up for the intendent purpose of stump shooting I Epoxied the nocks and inserts in and made up some aluminum collars to keep them from splitting, the inserts came out of both arrows I used w/o hitting anything hard like a rock. The Epoxy I was using was 5 min cure from ITW Performance Polymers.   (http://i567.photobucket.com/albums/ss115/earljeff/arrowhead001.jpg)

5 minute epoxies are not good for that application.  Go with 2 ton and you will be good too go.

How cold was it?  Some epoxies fail in below freezing temps....

Give a thought to using golf shafting epoxy. It stays flexible and can really take a pounding.

Best epoxy I've ever used is called PC Super Epoxy. Get it at auto parts store, Ace hardware, etc.  Never had an insert come out even when hitting rocks. Gives you 15 minutes of work time and cures in 3-4 hours.

Most failures using any adhesive that is a pretty good choice for the application (like epoxy for shafts to inserts) is caused by lapses in prep, which we all can be guilty of since shaft to insert bonds need to be prepped so carefully by cleaning and sanding for best results.

As a woodworker/builder I have had to accept the fact that failures in glues are almost always caused by something I missed or didn't do- whether poor mixing, surface prep issues, or tempuratures during glue up. I wish I could blame the adhesives, but I rarely can.

I just had four knife glue ups fail..and I believe it was cold temps in my basement that was the culprit. I could have made a mixing mistake, but I don't think so.

From this point forward, until Spring, all glue ups are taking place in my living areas upstairs.

The wife's going to love that!!!!
