Gentlemen, many years ago I was at an old engine show and found a full sized governor for sale, cheap. Being interested in all things mechanical, and this thing sure was mechanical looking I bought it. What I was going to do with it I had no idea. Last year while cleaning my garage and moving this thing around I thought, that would make a great model so I took it apart, made drawings and commenced to cut metal. Everything is made from solid and along with building it, it was supposed to operate. Well everything operates, the safety mechanism, the balanced valve, etc. but the flat springs that hold the balls in place won't flex enough to let it work properly. I wondered what I could make them out of and after cutting small pieces of flat spring stock and flexing them to see how they would work I was about to give up. I then used my feeler gauges for something and the idea came, cut some strips from feeler stock, but what thickness? I started at about .010 and moved down till I got to .006. The .006 seemed flexible enough when cut to the proper width so I cut some strips with my Dremel grinder and a small cutoff wheel. The balls were made in 2 pieces with a slot in one to locate the spring. The balls are held together with a screw that has a tapered head. When everything was assembled I filed the excess screw down flush and polished the balls. So far so good! The springs are held in place in the upper and lower collars by soldering. I made the collars and cut the locating slots at an angle with a .032 endmill. The springs were inserted into the slots and small wedges were inserted to fill up the excess space. Everything was then soft soldered,(50/50 solder). They came out great except for the fact that now that the springs were held rigidly in the collars they could no longer flex like they did between my fingers. I came to the conclusion that although this setup looks prototypical it won't work, at least not in this scale. I had so much time invested in making parts that I finished it up anyway. I now present to you the fruits of all this labor.
