Find two washers which fit close around the shaft. The larger OD, the better. Find or acquire a bearing splitting tool- the type that clamps. Cut up a soda/ beer can as a sleeve around the shaft and insert it into the lathe chuck. There will be a small distance between the faces of the chuck jaws an...

I was getting a little confused there too. There is the main head and then the "sub" head which we start calling the "cutter" head. That head was modified for R 8 collets which go much larger than Van Norman C5 collets. I think (uh oh) the V N collets maxed out at 5/8" ID. I never saw one above 1/2"...

More to the issue. That shaft is bent and I don't see any re bending advise taken. Look at that worm wheel for the fine feed and how it is deformed. These mills get moved around and whatever hand wheel or projection is subject to impact.

Sometimes, " a reader" must correct, while he can, to save a thread. Things are expressed in passion which don't mesh well to the board, so they have to go. They hardly ruin a thread.

Okay so all the measurements I conveyed are nothing.

In my notes; says that the Van Norman head is a sub head. They were supposed to fit #6, #12 milling machines. Mine is V5c taper. Measurements are the head is 9 1/4" long with 6 1/8' graduated base 3 mount holes. Some of this should apply.

Mine is a sub head to the larger Van Normans. We need a few measurements. I'm not sure it will fit correctly to the No. 12. Your quest must have revealed other options . Mine uses the original V 5C collets . That was the way to denote the meaning of "C" . It was circular with a key slot in the taper...

Sometimes when I walk into my garage, I'm fairly amazed. Who ran all those electrical feeds. Who re enforced the rafters so a two post car lift could be there. Who assembled all these things and not a picture to prove it. It was me, 30+ years ago. I dare not get on 12' ladders anymore and likely imp...

Man. You are way over my head. Spiral Bevel seems right but what he needs is transmission. A newer unit with newer bearings and he told me that the spindle was machined to R8 . So unless a person has a stash of 5V collets, the originals won't work.

That was the way. I've been reading this topic on different forums.

Van Norman collets or some taper. Can't say from here but I know that somewhere, sometime, someone modified the vertical attachment for an Index #60 milling machine. I just couldn't do that to a Van Norman head.

The Van Normans had vertical heads and sub heads, to where any angle could be achieved. What is the collet size, V5 / 5V ? I have to know a few dimensions before further discussion because I have a sub head.
