Agreed i mean these compounds we are playing with are only 25 lb draw, and the cheapo arrows supplied with em say they can be used in compounds up to 40 lb, I'll play safe and void the wooden ones for now.

OK I've made 5 arrows out of the glass fibre cheapo target arrows, I cut off the point of the target head but left the chrome body of it still in place IE I only cut off the pointy bit not the whole target head.

I then ran an 8 mm drill bit inside the 5/16 parallel field heads about 12 mm to remove the threading.

I lightly sanded the remaining target arrow head to provide a course surface for the expoxy.

I then mixed a small amount of Araldite rapid and coated the roughed up surface then slip on the drilled out field target heads, I ensured they were flush fitted and temporarily secured them in place to allow the expoxy to set.

Bingo A very sharp, very pointy steel field head attached to a budget arrow.

I'll try em out later and let you know how they perform from the Banshee.
