Hows that old saying go,”you can never have enough clamps”. I use a simple clamping system that is very affordable, flexible and most importantly repeatable. I use alot of curves and this is how I glue them up. One of the drawbacks to the common Male/Female forms used is that the laminations or parts must be milled perfectly in order to work with in the jig, as I began to use more and more tapered sections this became a constant struggle. I thought that if I could use one reference form and somehow work from this edge, the opposite edge could vary. For example, my chair rockers use the bottom edge for obvious reasons, the back leg jig however uses the inside radius, as this allows me to duplicate the arm and seat connection.
I use a flexible metal caul on the top and tighten the bolts or all thread with my cordless drill and then a ratchet.

Very cool! Kind of like a violin glueing fixture.

That is one clever idea, it’s a giant french curve! So It inspires me to think about the possibiitie, Maybe I’ll blow up my french curve template, and make your jig to be the same shape, only human furniture scale. Then design would match production….

Very ingenious. (Charlie note the spelling). I have a template for that will work with this type of setup. Thanks for giving me something to consider.

I enjoy looking at the pictures and trying to figure out what I am looking at before reading what it is . Wow you had me there. My first flash was a crazy harpsichord form star trek <laugh>

Great idea

Here’s a couple more pictures that may help explain the problem I was trying to over come. Many of the glue up’s I wanted to do incorpate several pieces as well as complex curved scarf joints.Photobucket
These above pictures are for a handle
To achieve a perfect joint it does take a couple fittings, the picture below shows a slight gap that resulted from a poor radiusPhotobucket
I have several simple sanding jigs that clean up the various radius scarf joints, I made these up out of scrap medex and used old sandpaper from the belt sander. I use a contact adhesive to attatch the sand paper, that way when the sandpaper does completely wear out I can use a heat gun to remove it and stick on a new piece.Photobucket
This picture shows the joints after I have sanded and fitted the pieces. Also show is the rough reference line I use to line up the pieces when I am ready to glue up.Photobucket
This picture shows the final fitting, I will remove all the pieces and glue it up, this glue up will be 8 seperate pieces Photobucket
Now I took these pictures yesterday and I will send a couple more this evening after I clean up the piece.
This picture is of a rocking chair runner using the same type jig, but obviously a different shape.rocking chair runner in jig

If anyone is interested in seeing different styles of this glueing system. Tage Frid goes into detail on this clamping system in his woodworking techniques #2 SHAPING VENEERING AND FINISH. As a matter of fact I would recomend this series of manuals as a must have for the countless tips, techniques and jigs that he details so well.

pretty cool clamping system… could probably be modified slightly for almost any task… well done…

Sometimes I see a project and ask myself: WHAT? So I click on it just to see WHAT it is. I usually don’t say anything but someimes wonder: WHY? If I do that, I never say anything because that would be rude.

This time, I asked: WHAT? And was very pleased with the answer. THAT IS NEAT!

A cool solution to a clamping challenge.
