Title: Epoxy Help
Post by: elktooth on August 24, 2008, 03:05:00 PM
So I did a stupid thing.  I normally glue up my carbon inserts with goat tuff or gorilla glue, but decided to try an epoxy this time instead.  After I epoxied all the inserts in I set them on the insert to set up for 24 hours.  When I came back the next day I had apparently put in a little too much epoxy and it had run down the inside of the insert, and is now preventing me from screwing in any heads.

I was hoping that someone on here might have a nice little trick or idea to remove the epoxy from the inside of the threads.  I tried using a small drill bit, and then heating up the threads on a steel adapter to try and heat the epoxy out of there, but to no avail.

Any ideas.

elktooth...   next time try cutting small pieces of tape and sticking them to the bottom of each insert, to cover the hole.  Keeps the glue or epoxy out.  Don't know how to fix what you got, but that tap idea sounds like the plan.

I will have to try the tap idea.  The only other option I came up with was to cut the arrow right behind the insert and then put an aluminum footing on it to regain my length.

Thanks for the advice.

I have gotten around that by heating up the threads of a field point with a flame and slowly screwing it down into the insert. Then screw it right back out. Works pretty well.

I have done that too.  It was pretty slow going, but I eventually got it.  The tap idea sounds a lot better.

also i forgot to add earlier...even though you are just cleaning epoxy from the threads with the taps. make sure you back it out a half turn or so while tapping....even epoxy can get bound up in a tap and break it. just to be safe so you wont end up with another predicament.:)i use taps quite a bit prototyping robot setups and i have actually snapped a tap, while tapping plastic, because i let it bind up.

I run a tap through mine as well... Seems that even w/o the epoxy the threads can get buggered up once in a while

You can buy a triple tap tool fairly cheap at an electrical supply house, it will do 6-32,8-32,10-32. They have a handle like a screwdriver and can be used for different chores.

When I glue inserts, I smear a small pellet of wax (string-wax or plain bees wax) in the after end (<= I hope this is proper English?! The German meaning here, would call for vaseline instead of wax    ;)    ) of the insert.
It will prevent the epoxy from blocking the threat, is simple and fast to do and be ductile enough to not interfere when you screw the points in. But a little heat would melt it, if needed.
And I use wax on the threats of my screw-ins anyways, to prevent them from rattling loose ...

Thanks for all the help guys.  The tap worked, and a lot faster than heating up an insert over and over again.  That took forever on the first two arrows.  They are now shootable.

This is a old thread, that I dug up after a rookie mistake yeaterday.
I did the same thing and now I have epoxy blocking the inserts. I drilled out the threads, and now I'll be running a tap through it tomorrow when I get home. I especially like the idea of wax to cover the hole.

Anyone who uses screw in points should have a tap in their tackle box. Just too handy!!
