Wanted a quick way to test rounds off of a progressive press to make sure that I didn't have any fail to drop powder.

Print both pieces and then use a 1/4 20 bolt in the back and a few washers to get the scales right to where a full load will tip it into the bin and a light round will sit there and not dump. I took a piece of brass that was fired and seated a round in it to be my "not good" tester so I can dial it in a little better. Uses another 1/4 20 bolt to go through the base of the teeter totter to clamp it to the catch or to the lip of an ammo can. If it drops in, its good to go! The pivot bar was a piece of 1/8 round stock, use whatever fits and allows it to move freely.

Works pretty well, ended up finding one that was missed, so saved me there.
