Just a short update. I’ve now got the parts I need to start on the new electromagnet testing platform. As my options for metalworking are limited, I’m planning to use an old dumbbell shaft as the basis of the roller.
In the picture are a pair of 1″ pillow block bearings, and some 1″ shaft collars. I can use different weights for the flywheel, and have some aluminium plate of various thickness to fashion the braking disk.
I’m planning to build this up using the frame of my old Elite Crono fluid trainer, so that I can put the Mk I cable operated setup back onto my Tacx trainer. Have been missing the ergo functionality when it’s raining outside! ;)
