Tungsten putty lovers check this out

Hey guys, found something interesting while trolling the tube earlier today and thought I'd share. Check out this video at about the 19:40 mark

Resin casting definitely opens up a world of possibilities

Wow! I didn't even know tungsten powder existed. Nice find!

Aside from awakening my need for a tungsten d20, I'm curious would one set up a single mould for standardised ingots of the resin compound or perhaps one more shaped specific to the casting you're building? I'm reminded of Bill at SST and how he did lead pours into silicone moulds of a car's interior piece as an alternative to slugs of lead

Either way this solves the oozing problems of plain putty for sure. Nice share!!

I also found a tactic that helps with putty leakage, if put some glue on the putty and then put it in the freezer the chill, the glue basically keeps the putty from leaking. I used it on one of my joust cars during the apocalypse joust. ("Buckle up" was the car if you watch the junkyard joust)

I've been experimenting with Tungsten powder for a while now... I discovered it through the sport of golf, as many golfers add it to the head of a club to improve swing speed and drive force. They drill a hole in the bottom head of a 'wood' and fill it with the powder and cap it off with epoxy. I've been using it in conjunction with gel super glue and baking soda to fill in plastic body molds and castings that have those hard to fill crevices. It definitely allows for a broader range of weight placement possibilities! I've also experimented with mixing the powder with a water-based PVA glue such as 'Elmers' to fill various interior components. I have yet to try the resin technique, but it looks promising! Good stuff... Keep experimenting!

Thanks for sharing, cheers

My outside the box thinking... Can it be added to clear coat ?? Just thinking out loud wondering if the weight would be distributed evenly across the car body would cause it to become top heavy? Some of the reading I have done with 60/40 or 70/30 split on weight for cars, where would this come into play spraying the entire car evenly.....

Could it be more for a road course verses drao race?

 


  • Applied overall to the car body, you've added weight but raised the centre of gravity and accomplished nothing to counteract any natural imbalance in weight distro. Always, points for the novel approach because that's how big breakthroughs get made — Chris_Hood

the tungston is expensive.



I'll stick with my low temp casting metal


cheaper, pours into plastic lowers, never seeps out

  • Yeah I've seen StoopidFishRacing melt this alloy into his builds, a fascinating take on weight addition in tiny spaces where carefully tooling a lead slug can be prohibitively difficult — Chris_Hood
  • Cactus Jack car has zero lead, zero heavy materials. Don’t need weight for a hill climb. — alva1370
