I like to always have the right tools near whatever station they are needed at, and have duplicates of a lot of wrenches, screwdrivers, etc. In collecting a bunch of CXA QCTP holders I see that there are four different sizes of the nut used for locking the depth setting. Also, there are two different sizes of set screws used. Further, the threading dial needs a wrench, the carriage lock needs a wrench, and the 3 jaw chuck bolts likewise.
Short of hanging a shelf worth of different wrenches, I built a composite wrench with 4 sizes that fit all the above. I couldn't think of how to combine the two hex keys, 5mm and 3/16" on that wrench, so I made a dual ended rod and bent it 90. This should be a pretty big help and prevent searching all over for a wrench when I don't even know what size I'm actually looking for.
I also got to use the mill pallet I made awhile ago. To fit the handle to the wrench body, I cut a slit in the handle end, and milled both sides of the body down to the width of the slit, and pressed them together. That worked perfectly, no pins, bolts, etc. needed.
I will save a minute or maybe two per day, perhaps.
