Building wheels

Ok so never even attempted it before so before i make a right hash of it some questions.

I am basically going to replace a hub. Are hubs of much the same diameter? Will i need new spokes? Fancy replacing knackered multispeed hub with a dedicated ss one (apart from niche and knee problems) will this cause spoke issues re length?

Cheers

Are hubs of much the same diameter? – No

Will i need new spokes? – Almost certainly

Fancy replacing knackered multispeed hub with a dedicated ss one (apart from niche and knee problems) will this cause spoke issues re length? – Almost certainly.
