I like that sturdy cast base they put this lathe on. You are making a really nice job on that retrofit.
There is a rule of thumb on electrical panels size. They always look 50% too large when you start, and turn out to be 20 % too small

Mechanically similar machines where sold by Knuth in Germany with a Sinumerik control.
The toolchanger is fiddly to adjust, if you have to take it apart, I can look for my notes on how to assemble it.
I have changed the pulley ratio to get a higher spindle speed.

At least with my Knuth lathe, the base is out of rather thin sheet metal and tends to vibrate.RotarySMP post=322596 userid=2917I like that sturdy cast base they put this lathe on. You are making a really nice job on that retrofit.

Problem: "looks 50% too large" seems to get bigger over time (with every project), but the rule still seems to hold water at the end.
