Ever had a mold that has a sprue plate coming up on it? Leaves a frustrating flash, or fin on one side of the base of the boolit. This not only harms accuracy, but if you have to seat a GC, its a real PITA.
Well, I recently got just such a mold, and I was scraping the flash off with my knife and wishing there were a more consistent way to do such an operation. I was considering fabricating something that looks like a case deburring cutter, only without that useless pin in the middle of it that forces you to only use that fine tool on an object that has a hole in the center of it, like the necks of our brass. Then, in the back of my mind, I seemed to remember that such a thing actually already exists. I seemed to remember that it was made by the Shaviv company out of Israel. Google is my friend, so I did a little poking and found that I was 100% correct! I found the very tool I was after on e-bay for $35 or something, so I stabbed some money in sombodys pocket and got it on the way. I figured, heck it's worth a try, and I can use it for lots of other jobs around the shop!
Well, it showed up today and I happened to be about to load some of the very boolits I was struggling with when it showed up. I ripped it open and tried it out.
Turns out it works just as good as I had hoped it would and cuts a very clean 45* angle around the base of the boolit, and the chamfer it lays on the trailing edge is incredibly even and consistent. You just press it straight onto the base of the boolit and twist your wrist back and forth rapidly. It has a built in ratchet advance, so it just walks around the boolit cutting the corner off clean.
I thought y'all would like to know.
