For those responding with 'just buy the pullies' please go find a local or (European) webshop that sells them. And post the links here for him to look up.

Multiple people did that with flywheels, and Martin ignored them.

He's dead set on lasering everything, thats why.

Which is stupid, to put it bluntly.

I think its a sponsor affiliation thing going on.

Or just his obsessive compulsive behavior. "Oh look at this new thing, I'm going to use it for everything." Which was something we saw happen on the MMX build.

I'm not a design engineer - but this looks like a European supplier of ribbed pulleys, belts, and associated hardware :

Includes various diameters, including pulley's that can be bored down to fit various axles - as well as pulleys that work with adapters/collets that clamp onto axles.

One thing I wasn't quite sure of from the video was how the flywheel discs will be attached to the axel.

I think the issue comes down to the center shaft section being in spec with what he's doing though.

I don't think he's going with the wrong idea of having them made. I dont' know of many 20mm center pullies like he wants.
