BitzaWood Revo now has a proper disk. Dan turned it down from the master pulley of a V6 Mondeo and added tool steel teeth.
Video to follow!

That looks seriously nasty! That tooth is huge!!! Top speed? Weight?
Nice! would like to see the video of it in action :D
...just a small observation - wouldn't the tooth be more effective if it were fixed with the sharp edge facing outwards?
@Liftoff, I'm not quite sure I know what you mean? The sharp edge of the tooth is at the very edge of the radius.
Dan then machined a gradual radius on the outside of the tooth so as much mass as possible is away from the centre and behind the sharp edge without protruding beyond the maximum diameter.
@Eventorizon about 3000rpm 2.5kgs. The setup was originally for those wood saws, for which I didn't want a huge amount of top speed.
The plan is to do a voltage upgrade to 6s which should double the RPM.
That looks seriously nasty. One day you have to build a featherweight K2!
I see what you mean, the radius on the outside of the tooth is at a tangent to the pulley - looking back at the photos its clear... That machine will cause some serious amount of damage!
It packs a decent amount of punch for a rather small diameter.
The disk is good but the rest is pretty flawed!
I like the look of K2, a similar low profile design is what I was thinking for the re-design. Reluctant to start though, don't know if I'll have time before April.
Give it to me, I'll do it I'll do it! :proud:
Haha, good luck. Post pictures of whatever you make. :)
Haha, well I have all the components! Just need to make the chassis and bolt it together.
erm, K2 ?
