I'm also not showing the thrust bearings that I will add between the mill body and motor mount block. Haven't decided how I want that yet. I need to get some in my hands to see so I know how I want to add them in. I have an idea but it resides in my head for now.

What's the length of those couplings just out of curiosity ? I need it to be around an inch. This was the concept so far.

Gail,

You are quite correct about the spring type couplings, they are much cheaper. The 1" Oldham ones cost me, in your money, about $30 for each complete one. But I always look on them as being good insurance, never need to be looked at again.

R,

If you follow the link I gave to Arc Euro, on that first page, it gives the general sizes of the component parts for each size OD.

John

I'll check it out. Been roughing out the part that mounts to the mill.

I decided to thicken the stepper side a bit so I could recess the screws.

Another milestone perhaps more important than the mechanics. Got the brains working I'll get it all tuned up once I get everything put together hopefully soon. Turns out there is a free cam generator add on with one of my drafting programs I use for work so that is an awesome thing (autodesk inventor- with hsm). I work in construction and use revit on a daily basis but inventor is part of my software suite and I use it a lot at home. If your not familiar with it it's awesome for mechanical design. You can model stuff and then make it work before building it. What I did the above models in. ^

Just curious - Have you decided on a thrust bearing scheme?

Actually I'm kinda leaning towards an angular contact bearing now since it would act as a mix of thrust and roller bearing. 5201 I think is the size I'm looking at at least for the y axis. I would just have to bore the diameter and depth in the end of the t shaped. Piece pictured above.

The Y has me thinking . For the X I used a couple of thrust bearing on the right side [might be overkill] - Bored into the existing retainer, each side leaving a web in the middle - Hand crank lock nut does the holding. Other end (stepper end) has one of the regular bearing types to keep shaft and stepper aligned. The Y . . . Only one end has bearing support and not a lot of room to work with . . .



Something will come up . . .
