Okay, so maybe I went a TAD overboard with these, but I needed the practice!
I needed to make a set of cambered cauls for both clamping as well as even glue-ups on cutting boards, etc… I also just received my router inlay set and really, REALLY wanted to try it out, so….......... Now I have a set of three cauls with a bunch of walnut inlays! I just couldn’t stop! Each caul has four walnut inlays plus a poplar plug (so I can tell which side is which when I take them apart). I wanted to make them look like the walnut was plugs instead of just inlays so I matched the same inlay on both sides.
The inlays are less than 1/8” deep to preserve the strength of the oak. The cauls are 28” long and can take a board 25” wide. With the current bolts I can clamp up to a 2 1/2” thick piece. Very adequate for what I am doing at the moment.
Oh yeah – I also tapered the insides a eighth of an inch from the center to each end – you can see this on the third picture pretty clearly. This ensures adequate clamping pressure in the middle of the joint as well as the edges. When I do a glue-up I am planning on using cello tape on the inside edges to keep the glue from sticking to the cauls.
It does feel nice using tools you build yourself!
