JPWH 6,033 #1 Posted November 9, 2023 Has anyone tried to cast a tombstone weight with lead? Would it be too heavy? What would be the pros and cons? 1 Share this post Link to post Share on other sites

Pullstart 62,838 #3 Posted November 9, 2023 I’d imagine it being soft… easy to damage. It’s common for racers to cast their own lead weights. The ones around here seemed to shrink when cooling, so they kind of look caved in on the flats and sharp in the corners. 2 Share this post Link to post Share on other sites
ri702bill 8,316 #4 Posted November 9, 2023 Too bad no one makes blow molded plastic shells like the wheel weights. Fill 'em up with ce-ment.... 2 Share this post Link to post Share on other sites
CCW 1,295 #5 Posted November 9, 2023 Years ago I cast my own scuba diving weights. In those days I was always looking at the edge of the road as I biked by and picked up the wheel balance weights that fell off of cars. I did this process on the kitchen stove using an aluminum pot. Today I would do it outside with a fan plowing the fumes away from me. If you do attempt this be sure not to stand over the molten metal and let any sweat drip in it. A dangerous explosion of molten lead would result. 5 Share this post Link to post Share on other sites

We concluded that filling one of his correctly-scaled printed tombstones would contain ~40 lbs of lead shot. We also think that there would have to be some internal reinforcement added to the all-plastic “handle” at the base. This would be insurance for the tractor driving over rough ground and shaking things! 4 Share this post Link to post Share on other sites

My concern would be picking one up by the plastic handle at the top with it weighing 40-50 lbs. Might be ok might not, will have to do some testing with a heavy density one and see! 2 Share this post Link to post Share on other sites
JPWH 6,033 #10 Posted November 10, 2023 Interesting thoughts so far. I can pour it safely and I think I have the shrinkage figured out. The weight will weigh about 75 lb +/- . I think the base may pose a problem under rough use due to the soft lead. Maybe a steel base for the lead to rest in would help. I'm trying to address issues such as mentioned before I make the first one. @Wheel Horse 3D made a nice pattern for me to make a mold. 1 3 1 Share this post Link to post Share on other sites
