Greetings,

Sorry to post a question and disappear, but my coworker is off this week,
and the MRI gods are angry...

Thanks for the great info.  I thought I had read (maybe from Lynn) that
welding the housings was a bad idea.  Have you actually welded any of these
George?  Got any pics?

If a light press (small hammer <g>) fit with epoxy is OK, then that sounds
like the way to go.  Shouldn't be too tough to come up with some mechanical
method of holding the tube on the outside.  Lynn, would there be a problem
TIG welding the aluminum tube to the outer portion of the housing?  Just 3
or 4 telltale spots would probably be enough.

Jerry, how did you ever shape the end of that tube without scratching the
housing???  Absolutely beautiful :-)

Cheers,
Rusty (off to Panama City)

I would take it eazy on the pressing. I have in the hangar one PP housing with few radial cracks in the housing around the tight fitting tube.
Buly
