stone making

[Tim Moss]

hey guys. im looking to make a stone in the area of 370lbs-400lbs. The biggest stone i have right now is a 330, which i believe is a 20.5'' dia. Dont qoute me on that though. anyway, i have had it weighed on a dump scale, so i know it is dead on. My problem though is that it is all concrete. i want to add a lead core to the next one. this way, i wont be a crazy large stone. im thinking i could add some old hex blocks i have
i dont know how to center the weight though. if anyone has any ideas, let me. thank you.

Are you making it with a Slater's mold?

I like to tap 3-4 ½” holes in round lead inserts then place the correct length of bolts in the insert so they are centered into the mold. Here is a picture of a custom 200lb insert.

no im not using slater molds, since i dont have the cash. Im using the plaster mold method found on ontariostrongman.com
