Biscuit Joiner Fixture

I use biscuits allot.  Let me say that again, I really use biscuits allot.  So, this is a great, simple fixture which greatly increases the speed and accuracy of using your biscuit joiner.  Currently I own both a DeWalt DW682 biscuit joiner and a Craftsman detail (or mini) biscuit joiner.  I use both quite a bit and this fixture is especially helpful with the craftsman tool.  I found the plans for this unit in Kim Stack's wonderful book, The Biscuit Joiner Book, available from popular woodworking books.  Since these plans are copyrighted you'll just have to go out and get Jim's book, but don't worry it's well worth the money .    I did modify the original plans by making this fixture to be used specifically with my Black & Decker Workmate (a GREAT little shop aid).

Then the box is screwed to the work surface.  That way I can always remove the box if I change my method of operation and no longer need the box.
