Mike,
Instead of posting pics ofmine again, here is the link to Rotex at lathes.uk. with good images.
There is a vertical shown. I have never seen one directly but your class certainly could have had one.
Mine is just like the blue horizontal one but the head is a Rusnok 70 vs the Rotex head.
Andrei,
As mentioned, mine is a model 70.? I think that is older than the 850?? Its good but I yearn for larger cutter capability for facing steel stock. The recent MLA cross slide project tested the limits of both the Rotex and Rusnok. The Y collet spindle limits me to 1/2" shanks.? The largest face mill (that I am still too scrooge to buy) is 2".? Anyhow, no plans to change.? Just keep maintaining and learning how to compensate for the ideosyncracies. Happy to own them.
