The finished gib key puller. Jerry notes, “Not a work of art, but very functional and robust enough for those stubborn keys that need to be tensioned and given a hard blow with a VBH (very big hammer).” Note the slot cut into the end – this allows the tool to be slipped over the head of the gib key.
Jerry found these bits and pieces in various scrap boxes. The pieces he used are marked in the photo. (A) A large piece of threaded rod and some nuts; (B) a piece of 2-inch gun barrel, which probably came from an anti-aircraft gun. It had been lying in the scrap box for years. (Any piece of heavy tube could be used.); (C) a big nut that became the spacer shown in the drawing opposite page; (D) a 1-1/2-centimeter-thick dropout salvaged from a profile cutter. It became Ring A also seen in the sketch.
The tool is placed over the gib key. The cutout slot in the face of the tool is slipped over the head and the whole tool is rotated 180 degrees. The adjusting cap screws are tightened (only finger tight) to align the puller to the shaft and seat the tool onto the gib key head.
This drawing shows possible improvements for making the puller into a universal-type puller to fit different shaft sizes. The tube could be a bigger diameter and instead of welding Ring A into place, a slot could be cut into the tube and a bolt fitted to hold a piece of bar stock into the slot, making it into an adjustable puller.

The drawing Jerry made after making the gib key puller. The drawing took longer to do than the actual tool took to make. Note that a few details are missing from the drawing, but become self explanatory when looking at the photos.
