Hi Ed, All,

I looked at HDPE cutting boards in Walmart, but they were too expensive 
and way too thick for the brands they carried to suit my purposes. Plus, 
most of them I saw had raised center portions with a deep groove to catch 
liquid runoff, along the top edge.  I needed thinner boards with an entirely
flat surface throughout.

I didn't get a chance to check K-Mart or other stores but I'm sure that with

I originally started out with 8 supports but with a test I conducted this

The HDPE supports hold the tubing very snug, so I didn't have any problems
at all with the tubing coming loose. This is some great stuff!
