I'm trying my hand out at turning my own wheels on my new Taig lathe. I have nearly no experience with a lathe and this my first project. Everything is working out beautifully except I can't get both sides of the wheels perfectly parallel. I can face one side and get it where the dial indicator doesn't move, flip it around and do the other side. But when I turn it around again, there is about .004" run-out. Can anyone give me some advise as to how I can get this tighter.
Thanks in advance.

The biggest factor is the mandrel that you use to machine the wheels. What are you currently using? I machine my own bearing wheels and my mandrel is about 1.200" in diameter to assure no flex in the wheel when I am machining.

No mandrel, I started off with a 1" length of 1.25" diameter rod in a 3 jaw chuck. I turned down 3/8" of the length to 1/4" diameter, turn that around and put the 1/4" part in the chuck and turn the other side. Of course, I intend to work these dimensions down but If I cant get it true at this size, how in the world am I gonna get it true when it gets thin enough to flex?
By the way, what is a typical width for razor wheels?

I used my dad's lathe for the first time over Christmas. It is a 48" lathe, but what he taught me is that a draw chuck is more accurate than an adjustable chuck. Use a draw chuck for more accuracy.
