Fellow Hunters -
Forgive my limited post "identity," as I'm prone to learning by osmosis.
I've considered several options to incorporate "pre-fab" shoulder studs on the armor. As a result, I opted to hand cut/saw the studs from pressure treated 1x2's..mind you trimmed down from there and sanded smooth with a slight bevel to each stud, and w/in reasonable proportions.
After, I recessed a flat-head machine screw w/ 2 ton epoxy allowing me to utilize the stud "head" as the bolt "head." Extremely effective, if not otherwise discussed on this forum previously by utilizing resin casts.
I should note that my search on the TDH site had limited reference outside of pitching a purchasable(sp) alternative item and/or BB's ref CD.
Please look for ref pics of the concept in application.
