Question about Hastings tubing

Hi all,

When you get the ends rolled, does the lip protrude into the ID of the tube? I plan to make a mirror cell with an intact outer rim and bang it into the mirror end. I'm thinking this will help push the tubing into true round a bit (I know that's not terribly important in this application, but still...). If the rolled lip goes into the ID a little, though, I'm going to have to leave the mirror cell end unrolled.

Does just getting the ends rolled help push it into true round a little bit, anyway?

Thanks,

Mike

Mike,

My Hastings 12" diameter tube has the roll going inward 1/2", making that end of the tube 11" in diameter.

Thanks Tom,

I've seen your picture before not too long ago, and I was trying to work out which way the rolling hung over, but now that you point it out I guess its obvious.

I think I'll leave the cell end unrolled as you recommend then. The cell itself ought to provide ample stiffening anyway.
