I special ordered m16 1.5 bolts from Home Depot to make my own. Cut them down and drilled them to .01 oz of what I wanted. I just cut a wide slot so that I could use a flathead screwdriver to drive the bolt in.
Totally unnecessary for my level of play, but pretty satisfying to make.
Edit to add: I just realized that this was posted down in cue making where I have no business replying with my hack job ideas.
