I have some cabinets and drawers to assemble. Corner clamps makes this a lot easier so off I went to ask Prof Google and YouTube and Pinterest for some ideas. I found some plans for clamps using wedges from WoodWorking Tips and also found some videos on YouTube by Izzy Swan. His first design seemed ok for me, but he also improved on it with a second design. This seemed a bit complicated for me.
From the ideas I drew a Sketchup plan which was a modification of the different ideas I found on the net (Pictures 1 to 3).
I drilled holes in the wedges as well as the clamp bases and I tied the wedges with some fishing line (That is what I had at hand) so that the wedges are at hand when you want to use the clamp.
After I made the clamps I realised that there are occasions when you want to join a T joint such as a shelf in a book rack. Therefore I modified one of the clamps by cutting the support blocks shorter so that they don’t stick past the corner to accommodate that.
Clamping a T joint
As the ordinary clamps use the wedges as a reference point for the corners
I had to make some additional wedges that are shorter when clamping a T joint.
The wedge clamp works fine for the bottom clamp and also supplies a foot piece for the assembly. On the top it seems to a bit of a bother to clamp with upside down wedges. Therefore I went with another design using regular C Clamps on a corner piece. I found this design and also this design compliments of Prof Google.
I got the idea to put a cover plate on top of the corner piece so that you would not have to hold it in place while clamping. It just rests on top of the corner and you have both hands to position and tighten the clamp.
Here are a few pictures of some views in the Sketchup plan
