Hi,
Apparently, the drawings of the sand channels that were given to me were the initial drawings without the revisions we made to make what I ended up with. As me and my friend discussed the changes by phone, he wrote them down, but didn't include them in the PDF he sent me...
Here is what I have to date, with my amateurish attempts to include the revisions. If these are not readable, I will send the PDF to folks interested. If there is not enough information here to reproduce what I had made, I will measure my made channels, and post the information until there is..
Thanks, David
the reinforcements put on the lower edges, and across the tops were 3/4"x 3/16" hardware store steel strap. Bob, the gauge of the sheet metal is 16 gauge.
