OK Wayne, It took me a little while to figure out how to upload pictures to The Big Blue website. I think I got it figured out now so here goes. The NWSL gearbox I used was NWSL 142-6. It comes with 1 worm(steel) 2.4mm shaft, 2 wormshaft bronze bearings, 1 28 toothgear (delrin), 1 28 tooth axle gear (brass), 2 gearbox sides, 1 bottom cover, thrust washers and screws. The steel shaft(worm) is what I noticed was hot. I did not consider that the motor was hot, it didn't feel any hotter that I would normally expect. I used the proper cup and ball universal joint to connect the motor to the gearbox. Here are some of the pictures:
First one is set up in the frame:[album]4617[/album]
second one is gearbox assembled with out drivers attached[album]4616[/album]
third one is with side removed revealing delrin wormgear/idler gear[album]4618[/album]
Fourth is worm shaft with bearing removed on right side. Notice black rings about 1/4" from worm. Bearing was a little difficult to pull off and close inspection which photo doesn't show(camera limitations) is small groves in the shaft.

Hope, you could offer some help with this,
Mark
