You know, I gave it some more thought about your suggestion.

Initially, I was interperting it to be for the entire method of joining the two pieces but then I looked at it as thought it were to "tie: things up.

So, I went to our local LEE VALLEY supplier and bought about ten, 1/2" x .125" round rare earth magnets.

Even putting 5 of them on either side of ONE section of two pieces of .125" ply. It hold OK but certainlywwon't hold when it's kickin' in at
125 MPH

I'll have to find a source on-line and get some good BAR stock

Thanks again
