Well my son tucker wanted a broadhead for chipmunks and small critters to shoot from his Maddog bow.This is what I came up with.Taken from an old cheap head.  

sorry forgot to paste the pic

Now that looks pretty slick.

How about some details???

I had an old broadhead that had an aluminum ferrel and cut it out with the Dremmel and cut the end of a 1/4 shaft in about 3/8" and slid the blade on.Then made small grooves for the back tabs of the blade.wrapped the shaft with Fireline fishing line and the cut 2 grooves in the blade and wrapped them covered them with duco cement and there it is.

Good idea. Looks like it will work great!
