Wow, I never would have thought of hardened anything for the pads. I, like most I'd guess, always figured some type of brass so that the pad wears before the part being turned. Did you notice wear on any of the parts you've turned over the years?
My guess as long as you kept them lubed to try and wash any chips away, it should work...on the other hand, keeping it dry might prevent the chips from sticking...

John Stevenson:
No wear, in fact it burnishes the parts if you run with a drop of oil on them.

The Old Axleson lathe we use at work has Steel arms. They need some kind of lube or the part will get hot :bugeye:

The main place you see bearings being used on steadies is when turning wood, that has more 'give'
Brass or phos bronze is the usual order of the day.

Hi Bogs et al...
I have taken delivery of my Drummond lathe c:1908 and among the accessories is the curious 'F' shaped device you can see in this illustration lying on the face plate on the chip tray.
I believe this is a travelling steady in which one fits blocks of wood drilled to accommodate the workpiece.
John Stevenson:
The problem with roller bearing steady rests is that it's very easy for chips to get under the rollers and indent themselves into the work or even stall the machine.
With careful use and making use of a cardboard disc as a protector can help.
The truthful answer is that just like collets there is no one steady fits all jobs, I have three lathes and 9 fixed steadies between them and I still have to improvise on certain jobs.
