Let me first start by saying that it's been a long time since I've worked with aluminum arrows. As such, there's probably a lot that I've forgotten. The shafts in question are Easton XX75 Camo Hunter and XX75 Tribute 1916. Inserts are Easton inserts.

In the past I would cut my shafts to length, debur the inside of the tube, then epoxy my inserts. This time around I wanted to use full length shafts, however, the issue is that my inserts will only fit if I chamfer the inside of the shaft to a very thin edge.

Otherwise my inserts only go so far.

The problem I see with the thin leading edge is that I think it may allow the insert to slide into the shaft on impact with the target. I never had to chamfer after cutting to length, only debur the inside with a few twists on a deburring tool.

I don't remember struggling this much to install inserts. I'm sure there's something I'm doing wrong, but I can't figure out what it is. I've never used uncut, full length aluminum arrows, so this is new territory for me. I'd appreciate insights into this situation. Thank you for taking the time to read this post.

They dont sink flush with a little pressure ?

I always tapped mine in and would smack them pretty good and that was after only after cleaning the inside, I would have to check the inserts for proper size.

Maynard - my experience with Easton RPS inserts (and other brands too) is that they require a fair amount of force to get them to seat completely flush into the shaft. It's those last few millimetres that can be stubborn. I also use Bohning hot melt (the amber type, not the blue low temp melt) thus I am wondering if your epoxy glue method without heat, is causing some difficulty. You're spot on though, with your thinly edged chamfer...something is amiss - there should not be a need to have such an aggressive chamfer.

Portlylawman & Tracker1: Not even with a LOT of pressure. That's why I thought, "WTF!" Which we all know means "Wednesday Thursday Friday!"

Just tried an insert without any epoxy, and it's the same situation. Got a pm suggesting taking measurements with calipers. Great idea; just need to find them. Recently moved to northwest Arkansas and some things are still boxed up.

Does it happen on both sides of the shaft?

I have noticed what you are talking about because I save cut offs to foot carbon shafts. Its like the edge is rolled. Maybe something in the finishing of the shaft process?

Update: I think CD was right. When I switched to my computer glasses I could see that the insert I was testing still had residual epoxy on it. Tried a new insert on a clean shaft and it slides in with moderate pressure as I remember.

Glad you were able to find a solution. Thanks CD!

Atta boy Maynard. Good old Easton aluminiums, an archer's friend.

I have always found heating the arrow shaft helps to push them in. It works out since I use hot glue, not sure how it would go with epoxy.

Cm shooter: I recently acquired an alcohol lamp for this exact purpose. This allowed me to try a hot glue for the first time at home. Have to say, I'm really liking it.

My sit down workbench is my great grandfathe’s old desk. I covered it with a piece of 3/4” plywood. Along the front edge i I drilled out a couple places just for things like stubborn inserts.
