This is the casting that's broken.
The break is in a bad spot. Might maybe could be fixed? Might last year's and might not?
I think I have another option that I am exploring. No one seems to have a used millright turret so I may stick a bridgeport turret and ram on it, for several reasons.
1. It will still be a short machine for use in a basement shop.
2. Cost will be about the same or less than a new part from D.C.Morrison, they want $500 for an unfinished casting, $700 if they machine the holes in it.
3. The mill right head will bolt to the ram, same bolt circle.
4. I can look for a nice used J head while using the millright head.
5. If I upgrade to a bridgeport J head later I will be able to get parts for it easy, unlike the millright head.
6. And all I have to do is make an adapter ring to go between the millright base and the bridgeport turret. The bolt circles are not the same. That's not difficult at all. I can even use a bridgeport riser and cut it down and weld the millright adapter ring to it. I just have to find someone with a really big lathe to do the turning!!
So I think this is the direction I'm going to go. Build a hybrid mill. A Millport, or a Bridgeright. LOL Upgrade!
