Chakram upper surface profile

DaveA · 3rd July 2014, 02:12 AM

Hello,

Here is a small picture of my chakram. It measures 9 ⅜ inches in diameter. The ring is beveled in a diamond cross section to generate aerodynamic lift. In shape, it very much resembles the modern "Aerobie" toy which was reportedly modeled on the charm. The patina of my example is mottled gray with light pitting. The composition is radial patterned steel, pattern welded for strength and not for esthetic effect. In other words, a weapon intended for use and not simply show.

Interestingly, steel versus brass chakra have different throwing distances. A steel one such as this has an effective range of 40 to 50 meters. A brass chakrum, due to lower mass, could be thrown in excess of 100 meters.

Here is a link to my website with further information:

Best Regards,

Dave A.

Why are brass ones lighter? Are they smaller, thinner, or hollow on the bottom surface? (Brass being denser than steel, there must be a smaller volume of metal compared to steel ones.) Are the brass ones non-weapons?

(Maybe the best thing to do is to get an Aerobie and copy it in steel.)
