Bill, I have no problem sharing my DXF files on the ATC. My design as all can see is based on many other type carousel designs. The only difference between my own and another very similar one is the hub design. The carousels weight is held up by the ATC motor box. This way the carousel can in no way come off the shaft inside the hub and have all the tools come crashing down. The shaft in the hub goes through a sealed angular contact bearing at the base of the hub. I made it this way to take the side load for when the ATC carousel fork goes in to grab the tool from the spindle. The ATC operates very smoothly with no play at all. I had a thrust breaing in the hub at first not thinking but quickly relised that the shaft in the hub did not have any side load protection. This would of caused a failure or weak down the road. I turned the hub to make it wider and turned the hub shaft down to fit the ID of the new sealed bearing. What A night and day difference it made, very solid. The hub fits throught the ATC carousel box so really the ATC carousel box is holding all the weight of the carousel. I dont have a DXF of the shaft with the new bearing dimensions but I will put up the old one. I will look for the bearing that I used from VXB bearing when I find the model number.
