The proper cauls also turn the corner and put that extra length of cloth, so that when installing the keys, the bushings have less chance of being pushed out.

But I had just acquired a console that I was going to sell too a local client, when I discovered about half of the keys bushings had fallen out. I checked all the other keys and the bushing were intact and looked good, so I decided to rebush the bad ones myself, but didn't have any cauls.

The snap-in end fit right down into the oval key hole, and compressed the bushing felt with perfect snugness, and after drying, and to my great relief, resulted in a perfect bushing job!

The elbows are slightly tapered which makes them snugger the further down they are inserted, and also stop against the bushing hole since they have a "t" shape about 3/4" up, very similar to actual cauls.
