Delving through the archives, I came across some videos I bought a few years back. I put some of them onto VCD and I should do the others now I have a TV tuner card again. If anyone wants a copy/ swap, let me know:

TinmanTech vids
Welding cast iron
gas welding aluminium

Eric Gorr vids
4 stroke engine rebuilding
2 stroke rebuilding
Shock rebuilding
Fork service and tuning

Still on VHS:
Twist of the wrist (boring and crap - book is better)
BMW K series 10000km service
