It is similar to the principals used on lathes or milling cutters. Cutting edge profile, material properties, cutting rate, and torque or resistance to cutter stall) dictate the material removal rate.... same as spinning disk weapons
well thats what i was told by 1 of the top American spinner teams
Tony,
A very good point. However the above calculation gives you a starting point to design a disc. It has been a while since there has been a similar thread so I thought it would be good for us to start getting some of that knowledge and experience out for others to read.
The amount of energy contained in a disc or bar is a completely different kettle of fish. The above merely gives you an rough indication as to whether or not a disc will be likely to grind on opponents or to be able to deliver either a shock or cutting blow.
Plus the greater area of tooth that is used during a collision, the less stress that the tooth will experience as a whole. I am not sure if any of the other spinners have noticed but my hardox teeth are somewhat blunted after a few hits on hardox boxes.
By this thread, 20,000rpm antweight disks dont work
Well, they dont work effective, they just make the Scary Sound of Doom
The antweight disks on Tims and my machine make more noise than any feather or heavyweight disk Ive heard.

Listen to that sweet sound.

A very useful calculator for working out the kinetic energy in your disc/bar/drum weapon.
sadly the units are all imperial but its not that tricky to convert from mm to inches.
If you play about with it you will see that the rotational energy goes up as the mass increases, the distance from the axis of rotation of the mass and the rpm.
Tim very nice (not)
and just go for 25.4 mm = 1 inch
If you google the conversion itll convert it for you. http://www.google.co.uk/search?hl=en...h+to+mm&meta=1
