I also noticed a minor detail that affected my motors' speed. At the end of the swing arm that raises/lowers the window is a small plastic wheel. The bearing of mine was absolutely caked with dried grease. It took a while to flush out the 50 year old grease. But, re-greased, it now it rolls easily and provides just that little bit less friction in the window mechanism.
That's another very good shout, and pre-empted a question that was already forming in my mind. I was testing the winding mechanism using a 6A battery charger I had, and the current being drawn was in excess of 6A, reinforced by the charger cutting out after half a dozen cycles (oops). So I was wondering just how much current was being drawn, albeit for "only" 10-20 seconds - probably a bit much more than the wiring enjoys. Was already going to add relays to the headlights, looks like another good candidate.
Ok, I know you're a fair way away from putting the motors back into the doors but when you do, consider fitting relays with a heavy gauge feed to operate the motors. I did that, two small relays (up/down) and it made a phenomenal difference to the speed they operate. Heck, they're like a normal car now ! The bonus is that you're also taking the motor current away from the switches so in theory they should last forever now.
