sideframes This was discussed before. I dont know what is available in other scales but years ago Con Cor made a C636. Basically a rolling manure spreader. But it did have the hi adhesion trucks. I just happened to have one and so what you do is remove the sideframes and completely cut off the sides The spacing is way off on the Con Cor. Then trim just the center part that has the high adhesion looking stuff. Next you need some flexcoil trucks from Atlas. Sand the back of the hi adhesion parts as thin as you can. Then do the same where they are to be placed on the flexcoil trucks. Glue in place and install in your Atlas C630 and there you have it! :tb-biggrin:
Thanks for the info guys. oldrk, I found a thread of of yours showing the bild of the Hi-AD trucks. I'll be doing HO, but I sure I will find a way to build them.
