puzzled by points

[jthain]

I am attempting to put new points on some ACC's that I have but the points will not fit into the arrows. They are the correct size points but there is an area just before the body of the point on the bit that goes into the arrow that appears to be slightly thicker than the rest of the shank of the point. Hope that is clear to the reader. The points just won't go into the arrows past this bit, ( one does go in but the rest of them don't).
I have lots of points like these of differing weights and they all appear to have this wider bit to them. Can anyone explain what is going on here.
They have all come from the same supplier and in Easton packets.
Any help is appreciated.

The points might not fit when they're cold (especially if there's residual glue in the shaft), but I've always found them to fit when they're hot and have hot-melt glue on.

Feel / look at the inside of the shaft where they have been cut. they should have been de-burred to about 1/3rd the thickness of the shaft ( about 0.003" ).

If it looks like there is a bit of aluminium left, then you will have to remove it yourself (very carefully ).

The points are supposed to be a snug fit though.

It would seem to me that the part that fits into the arrow tube first(slightly thinner) is a smaller diameter so the hot melt glue can stay on the pile as it is inserted. The last piece to fit in, is a much closer fit so that the pile is centralised into the shaft.
If the pile was thin along the whole length it could be off centre when fitted. If it was the thicker size all over, all the glue would be scraped off as it is being fitted.
Will the piles fit properly when totally clean, ie, no glue?
Is there a chance that the piles you have are for a larger arrow?
The thinner section should, when clean, slide in with next to no effort and almost fall out when turned upside down.
If you make the piles too hot, they expand even more and become more difficult to fit.

Thanks everyone for the input above but I have managed to fit them.
I thought that I had cleaned out the old glue from the previous piles but obviously not well enough. The old ones must have been shorter than the ones I am trying to fit and had left some residue far up inside the barrel. Enough to stop the new ones from going all the way in.
Again thanks to all who tried to help
