Glen (PA) and others,
I had my B/C swathboard off today in order to make a replacement. Since I believe you were asking for measurements of one sometime last year, I though I would draw it up and post it. It's a .pdf file that you can print out and use to make up new ones. I will use red oak but about anything will work. I have used just plain old pine in the past. Here's the file.
