Myself and Jameel Abraham recently completed this Shaker Inspired Workbench. I am the lucky beneficiary of this work. Jameel has told this story quite well on his blog. For more information and some funny video you can visit there by following the supplied link. I incorporated the BenchCrafted vises into my bench and I have to say the "Effortless Workholding" claim is for real.
Thanks for looking,
Ron Brese
