The knurls never bit down hard enough, what is your material and has it work hardened ?

Another point, were the knurls clean of swarf, metal particles.

The Steel is EN1 mild bright I cleaned everything before hand and used lots of oil , I am wondering it moving tool to the rear made the difference because I had to take everything apart and put it back together the other way round otherwise the adjuster would have been on the bottom and impossible to adjust.

As for the pins this is my first thoughts.
The end of the highlighted shaft will be threaded to secure them in place which will be set by a number of spacers I can put either side dependent on the stock I am turning. The keyway will allow me to fully tighten it without it turning.
Inside will be a sprung brass bar with a screw to set it against the stock.

The hex doesn't look thick enough to properly support the pins. I'd probably go for twice the diameter. You could always weld bushes or screw them in.

I did think about making it split but decided against that so it will be a case of feeding the bar through as best as I can. I must admit rigidity is one of my concerns which I hopefully will be able to cope with once I have welded this hexagon up, Maybe with the use of some extra round plates front and back.

The steady doesn't have to be accurate but does need rigidity. Don't be 'greedy: and make it too big   .  If you need to support the centre of a long bar,  consider how you get it on and off .

I find myself in need of a steady for my lathe and looking around was 1) not able to find anything suitable 2)  :bugeye: shocked at the prices. So whats a Madmodder to do?
I am making one, I started by making something to sit on the bed from some channel (pic1) this bit is complete. did not have phone in shed so actual pictures will come later.
Next bit is the make the guide ring? and so far I have bored out the holes for the guides themselves.
Will post more as I go along.

I ran slow with tool on centre and added pressure by tightening adjuster with oil.
