My University Bike Lock Design - Youtube Video

the material stops a chain saw at full revs pretty quickly
bigger grinder = same result
it'll just mess up the motor on the grinder before it has a chance at getting to the chain

the type of chain being used is pretty important
what spec is the chain ?

Sadly, it doesn't stop it that quickly in the case of a big saw at full pelt. The material relies on the 'hooks' of the chain grabbing it and pulling the fibers round and into the drive sprocket. As a cutting disc has a comparatively smooth running edge I imagine the fiber is less likely to be grabbed by the disc. It's definitely better than it not being there as the test shows the disc getting gunked up but I imagine a powerful disc cutter would laugh in the face of it... The length of fiber is important, the longer the strands are the better, obvs in the test piece they can only be so long but for the final product the longer the better.

Not criticizing cos I think it's a great design, I'm just thinking aloud and poking holes that probably aren't there!

And yes, definitely call it the 'Dench'
