All, Where did all the others come from? The topic was meant to be ATLAS / KATO only, please keep with the subject . Tom
If that was your intent, then you ought to have stopped after the first sentence in your first post. The second sentence effectively opened the door for discussion of "all the others".
I had to modify all the frame pieces using my milling machine. The two bottom sections had to be shortened to move the front truck back. I made an overlapping joint that was secured with brass screws. I had to drill and tap new holes in front to relocate the frame screws as well as modify the plastic insulator piece. The front drive shaft was shortened and the frame milled out to make room for the worm gear and relocated bearing blocks. I glued the bearing blocks in place with epoxy. The front truck was bashed together using the old Atlas truck frame and the shortened Con Cor truck mechanism. This is an image of each unmodified piece side by side with modified one. I highlighted in red the cut lines in the frame.
