Thanks All for the responses - this is helpful.

I have time, which is a good thing since I'm nursing a broken elbow after a spill a few weeks back on some wet Philly trolley tracks...It's good to have projects to keep busy.

I am likely going the route of drive screws if I can locate some. Reading the thread from a few weeks ago was helpful. I didn't think of the apoxy used to seal fish tanks, and double sided automative tape look's like a good, easy option.

Thanks Again - Great suggestions (as usual) - much to consider!
