johndaly Posted November 20, 2003 Share Posted November 20, 2003 http://www.tungstenspheres.com/ this stuff is very heavy, heavier than lead. It could be a pretty good chalklend. They ignored my e-mail, I'll try again later. Quote Link to comment Share on other sites More sharing options...

Guest Harlan Jacobs Posted November 22, 2003 Share Posted November 22, 2003 I doubt if many on here are fimilar with tungsten. Tungsten is 1 1/2-2 times heavier than steel than carbon steel. The one in the picture won't be seeing much airtime. Quote Link to comment Share on other sites More sharing options...
Guest Harlan Jacobs Posted November 22, 2003 Share Posted November 22, 2003 Now that I look at it closer, it looks like it is some kind of tungsten tool steel . The weight I gave was for tungsten carbide( 1 1/2-2 times heavier). The tool steel will still be at least 50% heavier that regular carbon steel.

bender Posted November 22, 2003 Share Posted November 22, 2003 I just got a reply from the company about prices. He wouldn't even give me an estimate and just said "We make them to-order, and we can't just make 2 x 2" balls". Nothing else. Bastard...

John Wood Posted November 24, 2003 Share Posted November 24, 2003 I believe that the Level 2 Dexterity Balls from IronMind are made of Tungsten. They are quite heavy. This site has various sizes of solid steel or marble balls. I recommend the 73mm bad boys. They are awesome and available nowhere else.

Rick Walker Posted November 24, 2003 Share Posted November 24, 2003 Thanks for the link John! The blue ones with the ying yang on them are exactly like mine. Rick Walker Quote Link to comment Share on other sites More sharing options...
nils Posted November 29, 2003 Share Posted November 29, 2003 I looked at these posts and tried ten minutes with my boule balls last night. (about 800 grams, 7-7.5 cm diameter). The idea was to facilitate recuperation of my tendinitis. And for my middle fingers that might work. But my hands actually got bit sore in some small, hard to define muscles, like from a real workout!?. Do you guys think that they are too big for medium sized hands?

supersqueeze Posted December 3, 2003 Share Posted December 3, 2003 This place (tungsten spheres) is 4 miles from where I work. It's half-way between work and home and I drive by it every day. I'll stop by and see if they let me in the building. Mike M. Quote Link to comment Share on other sites More sharing options...
The Mac Posted December 3, 2003 Share Posted December 3, 2003 (edited) If I recall correctly, the formulae for the volume of a sphere is 4/3 x pi x radius cubed (excuse the crap notation, I can't find the relevant buttons). Thus, at 18.5gr/cc: A ball with a radius of N centimetres would weigh x kilos. N X 1 0.07 2 0.62 3 2.09 4 4.96 5 9.69 6 16.74 7 26.58 8 39.68 9 56.49 10 77.49 (Somebody check my maths please!!) Therefore (discounting the handle) a Millenium weight bell would have globes of roughly 7" diameter, and a very heavy (469lb) "Atlas Stone" of roughly 11 inches in diameter (not that they make them above 4", though). Tungsten is defintely VERY dense. Not sure how it would handle the abuse, though. Edited because i messed up the calculations myself!!

The Mac Posted December 3, 2003 Share Posted December 3, 2003 Of course, if you get the 100mm block it will weigh 18.5kg (about 41lbs). Quote Link to comment Share on other sites More sharing options...
terry Posted December 3, 2003 Share Posted December 3, 2003 that would be interesting Quote Link to comment Share on other sites More sharing options...
supersqueeze Posted December 30, 2003 Share Posted December 30, 2003 I finally did stop by and they did let me into the building. The finished products are very expensive (4 inch cube = $1000) but they are also very cool, just not $1000 worth of cool! These little objects were very smooth and hard to pick-up. They told me they would sell pieces of scrap far cheaper than they would finished cubes and spheres - still pretty steep though. Anyway, my wife stopped by and sweet-talked a deal and she got a 46# chunk and a 76# chunk for me for Christmas. They are interesting as novety items and functional for training as well. Mike M.

Dan Cenidoza Posted December 31, 2003 Share Posted December 31, 2003 Those 73mm colossal balls look nice. Anybody have them? How much do they weigh? I use shotputs ranging from 4lbs-10lbs. Quote Link to comment Share on other sites More sharing options...
