I have made several of these in varying sizes for customers, and offer a smaller pre-built bench-top twin screw vise.
This latest is the largest I have made for a customer. After everything was said and done, and I was packing it up to ship it out, I realized that there is a definite advantage to having one of these over individual nut blocks and screws.
Thats right, depth. With my standard 18″ screws, you get a clamping depth of over 9 inches, after adding a 2″ front jaw. Over 9″!
Add to that the width between screws is over 24″, the thickness of the nut eliminates the need for a clamping strip, and you can see why I have decided to add this to my line of products.
Introductory pricing of $240 will run through the 1st of September, 2011, Regular price is $290.
