Made a few things to help out on the bench.
First, I took down my large metal working countertop a month or so ago, so I didn't have a place for my metal vise. So, I built a fixture to mount it on. The fixture can be clamped in both my leg vise and tail vise.
The second accessory was a bit more fun. More or less a bench on bench with a twin screw vise.
Walnut and maple, Mahogany (I think) Hand wheels.
25" between screws, 12" tall, 14" deep and 32" wide. Nice square, flat reference surfaces.
And, it fits with about 1//4" to spare below the bench dogs on its storage shelf below the bench.
all in all, halfway decent addition to the shop.
