A member on here was making sets of 3 and welding old silverware handles on. Price was reasonable (I know because I'm cheap and bought anyway) and they work fine. I used regular 14mm a couple of times before. The process is easy with straight wrenches especially if you pull the hard lines.

You really need to have them be different lengths so that they pass by each other when used in tandem. One holds the lock nut loose while the other adjusts the top gap.

Of course, there is also the method of using only the "3rd wrench" and one of the bent wrenches. Turn the adjustment nut down to increase the gap, or the lock nut up to decrease. There was a thread on it a while ago.
