Well, I'm trapped indoors due to weather and having two little ones that can not quite handle the wet cold yet causes the mind to come up with ideas.
I have a lot of mis matched arrows floating around for one reason or another and since I have settled in on my target and hunting arrows (for now) i went about finding ways to use these others up.
I was already at Home Depot this morning so I picked up a package of 8-32 stainless screws some nuts, flats and 1/4-20 wing nuts and went to work.
I do not have a grain scale so I used a VERY scientific method of weighing my head, first I held a 145 grain field point and then I held a finished wing nut game head and when they felt the same I screwed them on to some Heritage 150s I had laying around and went outside to shoot while the 2 y/o was napping. WOW they are great, I think I know what my SGH will be from now on. Next is to just put a washer behind a FP and see what happens
