I have been trying to come up with a Forward Of Center weight system that was easy and CHEAP. I did this because I found some broadheads that I really like and want to use this upcoming bow season Carbon Express XT4. They only come in 100gr.
So here's what I came up with:
I found some fishing split shot that was small enough to fit inside my Gold Tip Shafts. Oddly enough they all weighed 25gr each without variation.
I then took a peice of shaft to use as a mandrill to prepare it for insertion onto the shaft.
I tapped it into the small cut off peice to form fit it and pushed it back out using a drill bit.
Here it is ready to be inserted into the shaft for final fitting.
I then pushed it down the shaft with a .22 cal cleaning rod. When the lead split shot hit the tip insert I gave it a few extra hard taps to mash it so it wouldn't move.
There it is, you can add 25gr at a time until you get the weight you want to use. I've shot about 20 shots without the shot moving in the shafts.
