I reckon I could smash that to pieces Laughing

I'd love to know the cost on this! What power you aiming for? Are you in the uk and who's made it? And when are you likely to be testing it?

Why did you go to all that effort and then not upgrade the bearings. More thought required.

With spur gears you dont have to, they generate no axial forces and should be strong enough.

Yes there are no axial forces so why run a taper.

30mm/62mm/20mm
Std NSK HR32206C Load 48,700N RPM 8,000 oil
Upgrade               Load 57,000N RPM 12,000 oil

Now what RPM are your bearings doing with the different gear ratio?

As i said more thought required.

I know a guy in Trinidad who has the ONE that was made by Mazworx, he wants to sell it, but it's NOT cheap. Work of art though.

It's been used, but is still in good condition.

Some people take comments the wrong way when they have spent a fortune .constructive criticism is a good thing tho even if you have missed or not bought the right bits

Comment was about first box
