Re: [CAD_CAM_EDM_DRO] Machining question

Hi Kim,

If you had CNC, you could probably hog the support rods out of a block,
as you suspect. Boy, would that be a complex part to model. I suspect
it was a CAST part. I do remember some posts a while back about a CNC
controlled tube bender. It allowed holding tube at different angles for
each subsequent bend. Perhaps a set of jig's to hold the stock at
different angles, while it was turned, until the "dog legs" were turned?

Otherwise, How about turning a tapered SOLID rod to match the tapers of
the stand, then bend it as necessary.

Just a little hard to see stand in pix, but I think I get the idea.

I'd ask over on the Sherline list, might be a better place for this
question.
