Mark,
You make an important point about the blade rubbing. I'll update the article.
I don't understand you comment about 1/4" thick jaws working since they bent when I used them. In fact, I thiink they were more like 3/8" thick. What you you mean by "clamping range"?.
The "larger plate" is the one on the left end of the fixed jaw. Is that the one you are referring to??
I will update the article to say that these jaws are only intended for 90 degree cuts.?
Thanks for your comments.
Rick
