If you have 3/4” bench dog holes on your bench and a couple of handscrew clamps then in 10 minutes you can merge the two into a very flexible and powerful clamping system that works with small boards, long boards and even irregular pieces. I’ll let the photos tell the story … and keep in mind, the modification to the handscrew does not prevent you from using it as an ordinary handscrew too. I use them on my workbench and my sawbenches.
Hand screw with a dog peg added

Surface vice for short pieces of wood

Surface vice for long boards

Really long stock surface vice

Surface vice for irregular shapes.

Clicking on any of the photos will take you to the more detailed explanation.

There are only three real considerations:
1) The hole you drill for the peg should be plumb, so use a drill press if you can.
2) Oak or other hardwood dowel is better than poplar or other soft wood.
3) Regarding the size of the handscrew. Larger handscrews limit how close they can work together, but smaller handscrews limit the maximium opening of the jaws. I like the 6 or 8” handscrews but size them based on your needs.

I will definitely be making some dog holes in a couple handscrew clamps. Great idea, thanks for posting!

I probably should point out that Rockler has their 8” handscrews on sale right now for $4.99. They aren’t as solidly built as my Jorgensen’s and one of the handles was not quite straight, but they work well for a great price.

Swirt, I bought 10 of ‘em last time they were on sale. Yeah, they’re no Jorgensen’s, but for the price they’re great for “sure, I’ll drill a ¾” hole in ‘em and stuff a dowel in and see what happens!”

LOL Dan, notice I mounted the peg in my Rockler’s and into my Jorgensen’s ;) (not that the peg would damage either of them in any way)

Swirt I am building a small bench that will sit on top of my existing bench. I want to get my dovetails up enough to see them. I have looked at easy ways to set up a simple vise. I was going with a pipe clamp system. Dude this is the ticket. Its modular and with simple dog holes the setups are endless. If I break something its an easy replacement. Thanks;)

Enjoy SuperDav. I use mine quite often. My only complaint is that the dog peg sticking out the side makes them not fit on a rack as nicely as a non-dogged handscrew, and that is a pretty minor complaint.

The trick is to stay fluid in your thinking about how to use them. There are a lot of options.

Hmmm dovetails close enough to see them… you mean you can’t just stoop and squint like I do? ;)
