As requested, here are some pictures that show the swinging arm and how it mounts to the box. It simply uses two mortise hinges to attach to the right side of the box. It is a simple set up but it makes it really easy to get to the tools in the box behind the arm.
I'm still working on getting pictures of my latest finds. My wife took our good camera to Cleveland this weekend so I'm stuck with my $40 digital. I can't do my new Type 11 #7 jointer or my new #2 the justice they deserve with that.
Look for more a little later this weekend! As always, here's hoping you get some time in your shop and time to shop for your latest treasure!
