I haven't bored an actual wheel cylinder.. but I've bored countless similar jobs in the lathe.

I'd start with a 4 jaw for ease of centering.
Use a dial indicator with a finger attachment to reach inside and indicate both ends true, use a brass or rawhide hammer to help true the outside end.
Then bore it to suit. Checking diameter with a telescope gage and outside micrometer, or inside micrometer if you have one.
Press the stainless steel sleeve in place, use green locktite shaft retaining (press fit) compound. Then bore or hone if necessary.

Don't forget to drill the ports for bleeding and filling.

Check www.McMcaster.com for seamless stainless steel tubing.

I've heard plenty of difficulties with brass sleeved brake components, never heard of a problem with stainless steel sleeved ones. Stainless is harder and therefore less likely to wear and is even more corrosion resistant than brass.
While you're at it might as well do the best job you can.
