Hi Bushie,

Are you going to use that crank in the Linerweaver motor? and
how is it progressing?

I must admit I am a little excited as to how the 628 with a light crank
will run, not sure if it has been done before?

Cheers spanner

Oh and the crankpin requires EDM and I will have to get someone
to do that for me.

Hi Bushie,

Possibility of another 20% reduction in weight overall with
cnc I think.
Big bearings add friction But may not be necessary
Unless you have a massssssssive paddle Tyre

I like the nachi 22206 it has a higher load rating but i found the old surplus stock timkens on ebay for $50 each, since the design is the main thing im not too concerend with the counry of origin, mine say italy

FWIW timkens are made all over the place including in china, india

"Bigberg" was going to try lightening his ..

I think I will try it later on if needed, easy to get to and the main reason I made my crank lighter is to reduce spreading loads

why did you decide to go with the stock rod and not the carillo spanner?
