Hi, Wayne.

My apologies inasmuch as the hyperlink didn't embed correctly. This was what I used, though not ideal -

Lots of vendors sell those ^.  The other gentleman had shown one of these other boards, or similar -

........and if I were to start over, I'd have used the latter of the two simply because it's better suited for this kind of work.   Give it a run.
