OK....well been busy the last few days but I managed to get my long axis motor plate machined (with my older small CNC machine). It turned out pretty good and everything fit perfect (doesn't happen often

) I bolted it to the machine temporarily so I could see if everything was on track.
As you will tell by the pictures, I decided to go back to the fixed belt drive system and a single belt at that. I'm 99% confident that it will work. I don't know how well but everything seems logical about it. It's one of those things that I just have to prove to my stubborn self

, I won't learn anything if I don't try and if it doesn't work for some reason I can always recycle the parts for a recirculating belt drive.
