OK time for an update.
After receiving the replacement spokes from DSS, I proceeded to re-spoke the front wheel. Well, to say I was disappointed in the result would be an understatement! The inners did NOT fit properly even though they were the correct spokes. It seems the head (rim) end was not bent enough or long enough. Basically it was impossible to fit the spokes without severely bending them.
The rear spokes were also not sitting to my satisfaction so I cleaned up the originals and had them cad-plated.
I've now re-spoked and trued the rear wheel without drama. Lateral runout no greater than 0.01" and radial runout similar.
Had a bit of fun re-fitting the tyre/tube (brute force, ignorance, lots of soapy water and a few expetives!
) but now it's almost ready to put back on the bike.
The front spokes will be cad-plated this week then I can attack the re-spoking/truing.
The cad-plated spokes look quite good! Will post a pic later.
