Edward,
You need to let us know some more info here.
What is your draw length ?
Do you have any old arrows that you can try ?
My friend made a couple of self bows, and a one of these ended up a bit on the high side of his target draw weight.
He started out with a 2117 Gamegetter and played with the arrow lenght vs point weight and got the 2217's to work real good.
You might try the same approach. Round up a few 2217's and some 100 - 125 - 145 field points.
The alumimum shafts are easy to cut with a tubing cutter, and hot melt works great for the inserts.
You can spend hours playing around (I know, I've done it over and over...) but it's archery - so it's fun right ?
Another shaft you might try is a 2020. Like my friend always said - "if you don't have a bow that shoots 2020's - you should go out and get one"
