Is anyone having a problem with brass inserts pulling out in targets, or just coming out and the glue not holding. If not what the heck are you doing to keep them in? Tried every glue and still they pull out. I think it is a problem with the brass not adhering to the glue. Help!
I had the same problem.Try brushing the inside of the shaft with a brass bore brush and some lite sandpapering on the insert before gluing.
Use a 2 part epoxy and leave set overnight before using the arrows and you won't have that problem.
I have tried epoxy and JB weld with good clean shafts and inserts and still had a problem from time to time. What I have been doing now with great success is first I take a piece of emery cloth and roll it up so it fits tight in the end of the shaft. I rough up the first 3 inches of the inside of the shaft, then clean that and the insert with mek or acetone. I cut a piece of 1/4 wood dowel 1 1/4 inches long( take a shaft to the hardware to find a dowel that fits in the shaft snug but easy) Now dampen the dowel and insert with water then apply some Gorilla glue on them, start the dowel in then work the brass insert in, stand the whole thing up till it's dry about 24 hours. The end product will be an arrow with an internal footing that will hold up better than any you have had in the past. The are as tough as nails and your inserts will stay in.
I wipe down all inserts with 91% Isopropyl, let them dry THEN use JB Weld. Inserts never come loose.
Thank you for the tip! Makes sense as the wood is porous, as is the carbon, whereas brass isn't.
Clean the inside of the shafts with acetone and the inserts. Then use some Devon 2 part epoxy the kind that dries in 24 hours. It is getting harder to find. The other works but will eventually come loose. I think it is too brittle.LCH
I rough em up a bit and use goat tuff. I still have one come out once in a great while, but not often

This is the solution for sure. I rarely lose any inserts after I started this process. I use the expensive super glue to glue them in after this prep work.

Well, my brass inserts came in today and sfter cleaning with Is. alcohol and roughing up the inside of the shafts with 50gr sandpaper, glued them in with 2 part JB weld. I have serious doubts if anything is going to keep them in place. They did fit snug with the glue but on a dry run they literally dropped into the shafts, not snug at all...PR
Clean the inside of the shaft with acetone or alcohol before gluing. Any carbon dust inside the shaft will not allow glue to stick.
I called Goldtip and asked if they knew what I was doing wrong and they said they are redesigning the inserts that come with the shafts as they are pulling due to bow speeds. I told him that is not my problem as I shoot traditional. He did say not to sand the inside of the shaft at all. Only as a last resort as it will compromise the shaft. He did say to clean and try to scuff up the brass and then try different glues. Thanks for the help I think I might try a few and see which one I have luck with. I have been cleaning both the shaft and the insert so I know that is not it. I noticed that the glue seems to stick to the shaft but the insert is clean when it does pull because my buddy had one fly off after his arrow blew through the target and then stopped in the middle and the insert just kept going. About 11 of the 12 glued failed. I got two new glues today so we shall try them all.
What vtmtnman said. Bore brush the shaft, sandpaper the insert, and JB Weld to stick. Not even a torch will get it out after that.
James- can you explain again the dowel idea??? I am confused. . .????
