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.
I may have to give that a try to see if I can get some of my arrows in my collection to spine just right for me.
I use to melt the split shot in hand gun casings (spent rounds) to get my blunts up to 160g for stumping.
Hope they hold tight for ya!!
Just a suggestion for conversation....use those blue pliers and lightly shape that split shot just a bit, stick it in the nock end and ram it down the shaft to back of insert. Then drop a few hot melt crumbs on top and lightly heat.
I used to do that with the bullet shaped worm weights.
