Custom trunnion bush puller

I was pressing my new end bushing onto my Spider trunnion when I realized it was not aligned properly, so it had to come back off. Usually this means damage or destruction of the bush. I had not completely pressed it on and had just enough space to place this homemade tool between the bush and trunnion bar and remove it. The tool is a plate of steel purchased at the local Home Depot and various parts of my bearing puller/splitter set. I drilled a 5/8 hole in the center of the plate for the trunnion bar shaft, followed by two more holes, one on either side of the center hole, to accommodate the bearing puller pieces. I then cut the plate in half with my die grinder (right through the center of the three drilled holes) and assembled the two pieces as you see in the photo below using large washers behind the plate to trap the pieces together. From this point I simply installed the puller to the two threaded rods and off she came.
