I have had many requests to re-post some of the articles that used to be at the former WK Fine Tools website. As time permits, I will continue to add those articles here.
This one, on the ratcheting parallel guide has been the most requested. I apparently did not back up the photos for this article and thought I lost them. Finally, after digging thru sent email from four years ago I was able to recover them.
The ratchet bench currently resides at the Wood & Shop School. If you are taking a class there be sure to try it out.
This article also includes a section on how to alter the Moravian workbench bench design to accept an angled leg vise.
