Thanks Steve, for the best wishes & for sorting out the crank for me!
I`ve sent the other one down for repair.
The bikes nearly ready.
Last Sunday I decided it was a good idea to try & cut off the top of my left thumb with the Dremel.

Should`ve changed the tattered latex gloves before they got caught in the circular saw attachment! You live & learn, I suppose.

Should be the first fire-up of the racer tomorrow, hoping all the electrical bits work as they are untested & unproven as of now.
Fingers crossed! (No thumbs!).
Roy.
