When using aluminum arrows, shooting 20 yards or less, do the broadheads have to be aligned perfect on the adaptor. I'm using woodsman broadheads. When I spin I get just a little wobble on some. I've mounted the heads on the adaptor with heat melt glue, but I just can't seem to get all of them perfect. :banghead:
It's possible that your broadheads are on the adapter straight and your insert in the aluminum shaft is not centered in the shaft. Or, if the tips of the woodsmans have been filed crooked or have a bur on them they may wobble. Then again, they just might not be aligned on the adapter perfect.
I tried that Mike and it helped a little, but out of 5 broadheads, three still wobble a little. I have the long adaptors. I have ruled out the arrows by trying other broadheads that spin true.
I don't have any sort of jig to align them, so now I'm at a loss, except to keep heating and fiddling with them. :knothead:
That's all you really can do. Sometimes they drive you crazy. Others will pop right on true like they couldn't wait to get there. You have to get them perfect though or flight will be affected. On thing I found out the hard way is that no matter what you do, you can have a shaft that is bent at the very tip (especially true for used arrows). You may have to cut back or even cull the shaft. :(
I use 5-minute epoxy,, that way I can spin test them and get them perfect then just let them sit until the epoxy sets up.... doesn't work for you right now I know so If I was you I'd get a mapp gas torch and while the torch is burning and sitting on a table you can then get the heads straight by holding the shaft and using pliers (very gently) to turn and work the broadhead.
I'll add to what Mike Walker said...first of all make sure to get the ferrule of the broadhead hot enough. (it can be a little tricky to do and not heat up the blades) The hot melt should flow quickly if the ferrule is hot enough.
Turning the broadhead on the adapter (a couple of full revolutions really does it)spreads out the glue for better bonding and even distribution.
The Woodsman is a very easy head to align so it's likely something simple that's foiling your attempts.
You can make a spinning tool by taking a 4 X 4 with nails making two different X's at two different spots on the board. Now you have a craddle to lay the arrow in.
Next, slide everything up next to something vertical and put a very small dot on the vertical piece...as you rotate the arrow in the craddle (with a 3 blade, I alternately put each blade straight up) watch the tip. Where the tip is at the lowest point, heat things up and press down gently on the tip in order to bring the lowest point up. repeat until it spins true!
Nice Idea jeff,,Yeah they can be tough but Charlie gave ya great advise,,Give them a couple good turns to even out that glue and then retry,, :thumbsup: :thumbsup:
