Hi there gnarlyEric and everybody else.
I made a number of these clamps during my boatbuilding training some 37 years ago.
Funny to see how similar they are to Erics.
Mine are made of birch with a hinge and a spring compressed inside.

cheers Lasse-Sweden

Having the spring makes them really handy too.

Man, thirty-seven years and you still have them! Amazing. I have a good many, mostly of oak from the early ‘eighties so that’s over thirty years. I had not thought of it that way. I guess I need to rummage around and drag out a few of those old things.

I guess we’re all going to “rummage” through our stuff and find those ‘antiques’ that we made many years ago…It’s amazing how time flies!!

Mechanically, these are so damn elegant. I wouldn’t be surprised to see new versions of this popping up on LJ, thanks for passing on the knowledge.

Hacksaw blades could be used for the brackets it seems like, based on apparent size…

I’ve got some just like that with the cam handle, about the same vintage too. Mine use the low tech leather hinge. I might have to add some springs to mine. Very nice.

From The woodenboat thread;

In “Planking and Fastening” in The WoodenBoat Series, ISBN: 9780937822418, chapter 24 “The Brenne Clamp”, is about making this kind of clamp, complete with dimensioned drawing. All together, there are five chapters about clamps and their making and use.

A fellow listed a link the woodenboat series.

There’s also an old woodenboat mag that has them, but without the spring, which is a great idea. I’d look it up, but I’m out of town. I also built a half dozen years ago.

Have your say...
