All I know is this thing works for me and is a great third hand.

Below you'll find a couple of pictures and descriptions of the materials I used on my version and also two PDF files that will give you a start on the grid work if you decide to build one for yourself. I stress that none of the materials used are critical, use what you have on hand.

The one pictured is relatively small because of a lack of space. I started with a scrap of 1/2” ply 24”x 8 1/2”. Glued the paper template (see the PDF files) to this using the 3M 77 and sprayed a couple of coats of the Krylon clear on that for protection. You can use as many of the templates below to fill your board if it’s longer or wider than the templates, just make sure the center line is straight.
