Ken,
Your answer was correct for some situations.
However, I have found that for very thin blanks like ice rod noodle blanks I much prefer to have the rollers abut each other. I set them so that there is about .003 inches between the rollers.
Then, I do offset the top roller to the side between them to allow for a good clamping effect on the blank.
I find that if I offset the rollers, that I can get a bet of a bending effect when the blank goes through the offset rollers.
But, unless you work with these very thin angle hair spaghetti type blanks - then I would offset the rollers every time as Ken suggested. For the rollers that I use for "normal" sized blanks - I use the offset method as well.
Frank, Here is a picture of the rollers that I made for use on my full length rod lathe. I wanted close equal support for high speed turning operations, so in this case, I have the two bottom rollers side by side.

This is a picture of the rollers and stands that I use for ice rod building with very small diameter blanks. These stands use shower door rollers with an O ring in the groove. The two bottom rollers are on the same plane and nearly touch.
The top roller is off set and comes down to the side of the two adjacent bottom rollers.

This is a picture of the steady rest that I use for the majority of my rod building today. The lower rollers are offset, just the width of the outside O ring. Then, the top roller drops down beside both rollers:

Good luck
