Yes I really am pulling the pins 1 or 2 at a time. Like I said time consuming. I plan on building another hammer mill. Will post about that when I ever get to it lol. I just wanted to share alittle this morning. Hope it is helpful to someone....

Nice stash, by the way!

The quickest way is a hammer mill. However I am at this moment using the little dikes you see in the pic. I grip the soldier ball and slip the pin out of the carrier socket. You can take a piece of pipe with a cap on one end about 3 inch in diamiter. Slid the ends in there and take something solid such as a piece of 1 inch rebar or whatever is handy. Smash the heck out of the things lol. Then seperate. My truck is down for the day so im just tooling around with this. There is just over a pound in the jar. Asfor return I honestly cant say. Some times its really great sometimes not so great. Due to plating differences an such.

Thanks

Honestly no. It varies so much and I have never taken the time to weigh things befor and after. I weigh my pins lol I like to know what the weight of my work is. I may break some down later and see what the weight ratio is. But may take a few days for me to get that bored lol. I wish I could help you out. Only thing I know to say is. I break all mine down that dont take heaps of work. To me its better to get between 45 and 120 bucks a pound for pins as to 2 bucks a pound of plugs. However your 200 pounds may only make 15 or 20 pounds of pins. Im not sure alot more plastic then pins.

I'm glad you posted on this topic. Pulling pins is an idea I've been wrestling with myself. In regard to a hammer mill, can you tell me what you use? Did you buy one or build one? If bought, what brand do you recommend? If built, how do you build one?

I used to have one I built. I used an old military 20gal barrel. Welded angle iron inside it straight up and down 4 pieces. cut a door in the side of it with a latch. took some old scooter wheels and drilled holes on each end of the barrel for a shaft. Used the bearings in the scooter wheels for the shaft. Made a rack out of an old bed frame mounted the washing machine motor to the rack Used a belt off a 302 ford engine to run the mill. I used descent sized rocks to smash the ingredients. When I build another I will post about it.

The surface was rough like, not as much as a golf ball pits. Not sure if they started out smoothly polished or not. I've seen similar sized ball bearings in large equipment, such as the turntable on a crane, and in oilfield equipment or such as that

Yea I would love to find some of them big steel ball bearings. Would be ideal. And yes im speaking of building the same kind of machine only MUCH smaller lol.

If you pass by any oilfield drilling equipment maintenence yards, it might be worth asking about there, who knows, they might have a bucket of them laying around somewhere

Thanks Bear I will keep my eye opened not many oil fields in my area lol. But im guessin ebay may be a place to look. I am in KY Hardin county to be exact.
