I thought I would post some of the repairs I made while rebuilding my '67 T120 (which is not finished yet). I would not have been able to do the repairs without a workshop, lathe, pillar drill and various other tools and facilities that a workshop offers. I decided I would repair what I could, and replace only when absolutely necessary.
I got the bike with the following parts completely or partially f***ed: forks, broken off sidestand lug, front drum, rear drum, wrong and loose steering head bearings in the frame, and that's before I got to the internals.
Before I took the thing totally apart, I wanted to make sure that the wheels were in line and the frame straight. I live on a farm so I had some handy, straight steel poly tunnel tubes that I swiped from a pile. Since the swinging arm spindle is hidden, I felt it was OK to centre drill each end, so that I could use a large pair of dividers to check that the rear wheel was centred in the swinging fork and then see if the front end was twisted. The rear wheel spindle already has centres drilled. The non-stock alloy rims are WM2 front and WM3 rear, which is good (spreads the rear tyre better). I used spacers either side of the front tyre when checking the wheel alignment.
Turns out that the alignment was spot on. Front rim was centred in the fork, the steering head is not cocked and the spine is straight. That's a good foundation to begin with. I have been around bikes, and crashed ones, enough over the years to see by eye if things are out of line, so in this case I didn't use measuring equipment.
