Thanks, Kent. I had seen John's post concerning the erroneous dimensions (I've done it while woodworking). I'll copy John's text into the PDF and annotate my drawings A/R. If I build I want to make sure it's correct the first time. I hope you can understand why I'm concerned about the lack of the opposing "witness marks".
BTY - Do you know how to remove images from the threads? The usual "delete", "right click", etc., didn't work and made it worse.
Thanks again, Gecko
