G'day,
trying to make oval tubing from round tubing...
we're trying to make oval tubing (two half circles seperateed by tangential
parallel sides)
if we try squeezing the tubing we end up with the sidewalls folding in on
them selves, and the ends "pointing" themselve - the oval looks like a squeezed
figure eight
The tubing (with the same perimeter measurement) is 1.5" OD and less than
1/16" wall thickness and we need pieces in the order of 24" long
On the presumption that a internal mandrel is used - how is it done?
Do we start with a round slip fit which gradually changes to the shape we're
interested in? Do we push it through, pull it, roll it?
unfortunately we're not looking at needing many of these, so specialist
manufacturing
isn't an option.
Thanks,
Des
