I have been using Cyber 007, made by R.S. Archery Products, inc. for 2 years to set all bushing, points, inserts. 60-80 dozen arrows yearly. rarely does this glue fail in any condition. it is not an epoxy, so there is no mixing.
www.rsbowvise.com/archery_products.htm is the web site. your local pro shop should be able to order it for you. if not the site list several folks you get purchase it from. i order mine from kinsey's wholesale.
unlike goat tough where you only have 3 to 5 seconds this product gives you between 20-30 seconds and after 5 minutes you are ready to shoot.
I use the G5 straitening(squaring) device on the shaft and then put my insert in and square that up.When I securely screw in the broadhead to the insert or 0 ring.I then spin the arrow to see how it is true.
Usually,ever since I have used the squaring device this method works 9 times out of ten.
If it don't, I guess I can just try and put a different broadhead in,or O-ring and see if it spins true then.
I was thinking of just getting some slower epoxy to spin the broadhead and insert on the shaft.
I wonder how to square up the insert without it being on the shaft before you glue it in?
Hot Melt it and use a marker to line it up again maybe?
