Pinless leg vise (without a criss cross)

I build a pin-less leg vise for my workbench. This design is very simple, and very simple to make. The parallel mechanism is all wood. There is a hardwood parallel guide which runs against a strip of Birch on the under side of the leg rail.
Compared to more popular methods like linear bearings, St Peter's cross, or chain-contraptions, this is a winner. It's arguably simpler than building a traditional pin board.
I don't know if this idea pre-dates UA-cam, but I first saw this method used in Corneel du Toit's video. Please watch his video if you're interested in this design: • Easy DIY Pinless Leg Vice

You posted this the day I started looking into building a leg vise. Looks great! Thanks for sharing your process!

Terrific build, I learnt stuff, many thanks.

$300 bench plane but you grabbed the Millers Falls for the end grain... I'm a huge fan of their tools, planes mainly. Nice vice build too!

The Millers Falls is my daily smoother. Wouldn't trade it for any other.

Interesting. Perhaps you could do something similar using a heavy-duty drawer slide at the bottom.

Beautiful wood in vice leg. What species? Super simple idea, well done on the build

[@brochobo]

Thanks, it's redwood, the guide block is mahogany.

I advise you to use the pins (you'll need to make provision) whenever you can to prolong the inevitable. It will loosen.

[@brochobo]

I think you are right. It will loosen, but how soon, and how irreparably? I will find out if it was worth it.

Interesting take on the "pin" board. Why the inserted piece of hardwood on the bench stretcher? Could it not simply run on the stretcher?

[@brochobo]

That's for wear resistance, since the stretcher is very soft redwood. It also slides more smoothly on hardwood.
