As silverbullet said u can get one slightly smaller and add a base plate to get it up to center.
I'm wondering.....rather than ebay, I found that grizzly sells the entire steady rest assembly for their 8, 9, 10 and 11 inch lathes for around 100 bucks. Just wondering if buying one and using an adapter plate on bottom would be a lower cost, but workable option.
A long time ago I made a spider for my lathe for this type of thing. It takes a very large bearing and some cold rolled steel

The cage around the bearing has set screws in the middle of the bearing pockets to give some adjustment to place the bearing on the center of the spindle axis. I've only had to reset the center once after I took the frame apart to turn the bearing around 180 degrees. The four screws on the aluminum collar take care of centering your project metal.
Here you can see it in use holding material for my form1 can:

It also works very well for holding long barrels steady at the end for chambering. No friction, excess material strength needed.
Nice, I could only wonder the price of that bearing purchased brand new.
I'm very frustrated, somewhat with my machine but mostly with me. The short version is I need a steady rest but cant find one.
My 2537 12" turret lathe has been making chips for a while now. I'm not by any stretch of the imagination a machinist, but I have been able to make what I have needed so for. All of my projects have been small. I've made bushings and and a few odd parts here and there. This is just me in my shop at home for fun.
But I have a big project to work on for myself. I have been planning on making a few suppressors for my rifles. I've got all the legalities covered and all is on the up and up.
The issue is I have some 4140 round bar about 14" long to make the baffles out of. Baffles will be 60* cones to fit inside a 1.5"ID tube. The best, as I understand it, way to make them is chuck the bar up, and use a steady rest to support it while I work a baffle at a time on the far end. So that means I need a steady which didn't come with the lathe.
Necessity is a mother, so I make a steady.........The first version was a hexagon shape about 10" diameter. I'm sure you can already see the problem. I made it from .5x.750" bar stock, welded, threaded 120* apart. It looked good, but when I put it on and turned the machine by hand, there was so much flex in the fingers I was afraid to even turn the machine on. So back to the drawing board.
The second steady was made from wood. I used 3 layers of 3/4" birch glued and screwed together. I had a 4" hole in the center and again fingers at 120* apart. The fingers were 1/2-13 bolts which I turned and tipped with brass. Unfortunatly there is too much movement in the wood itself I guess. As I start to take light cuts on the surface, it works loose and starts flexing. I have been watching Ebay and can't find a Logan Steady rest and dont know if anything else will fit.
I'm really disappointed in my self and in the project so far. So much so I had to just leave the shop. As bad as it sounds I am considering selling the Logan and getting a new import lathe that comes with a steady and tail stock, which I also don't have and would like to have. Right now my project is stopped and I can't do anything about it.
I just wanted to try to share the weight on my shoulders, confession being good for the soul and all, and share my tale of woe.
