Yeah, and that "someday" finally came for me and I threw the darn thing out, in the garbage. Now if I didn't have a tape measure I would have to find one somewhere or buy a few more but I wasn't going to waste wood as often with that mistake, again. Went on for years until I had enough, one day....LOL
