Can't remember now. Been a few years. Pics here may be of use.
Cnc rotary table.
Some of you would have noticed I aquired a vertex hv6 rotary table yesterday. older generation still with bearings rather than running in the machined castings. needs a clean then I'm going to look at fitting a stepper to index with. Next to no backlash either. Came across this...

I have a Hoffman RT, the hand wheel is similar in that it hangs lower than the base
Both clamps free. Anyway will have to wait a few days now. I found the vertex manuals so will have a look.
Very interesting thanks!
Well I got the shaft out. Not a good sign I had to use a hammer and a rod to tap it out.
Bore looks great. Shaft looked OK but when I cleaned it up noticed a very slight dulling on one side. Yes I think it's bent.
Won't fit back in the hole only halfway.
Now what do I do
Any way of straightening it by a thou

Just kiddin. Flame straightening is good for plain shafts but with all that machining, it's probably a very simple one off bend right at the shoulder.
Quick bonk on a flypress will fix it. So long as you hit it exactly right.

Need to get it between centers and get the dial on it to determine where the bend is, mark it and get it in a vice (soft jaws) and hit it with a copper hammer...might take a few goes but you should get it within what you need to allow it back in the table
Yes, this. And don't rush it - if you have to make a v block or an attachment to your press then do it.

Yes if it really is only a few thou. As you say, all the effort up front in measuring and discovering exactly where the bend is is the key issue.
If it were me and I didn't have a flypress I'd prefer to go with a more controllable bend with the shaft in a vice and a long bit of pipe (or bending fork). At least then you can feel for the amount of bend and also direct the force much more accurately.
I have 2 flypresses - but no balls - and a bent shaft

Looks identical to my vertex, can’t help you too much with straightening shaft but I have Manual and parts diagram at home, though you can probably download from web….
I can send you pics/scans if you want (you may not need them as you already have it apart) but I’m in Turkey with work at mo and not home till Friday

It's ok thanks - downloaded the manuals. Mine is the earlier version though with ball races etc - better quality than the newer ones - or would be if the shaft wasn't bent!
Well you did an amazing job on a very bent feed screw on that milling machine! If that can be straightened anything can!
