shows and engines

We’re deep into the show season by now, and it looks like I’ll only make a few shows this year. With three magazines to oversee (I’m also responsible for sister publications Farm Collector and Motorcycle Classics) finding time to do everything I’d like to gets harder and harder. I’m crossing my fingers that I’ll make Portland in late August, but I know I’ll be at the Old Threshers Reunion at Mt. Pleasant, Iowa, over the Labor Day weekend and then the annual Power of the Past Antique Engine & Tractor Show, Sept. 7-9, 2018, in Ottawa, Kansas. Just about everyone knows about or has been to the Mt. Pleasant show, now in its 68th (!) year, and more people are hearing about and taking in the Ottawa show, a relative young-un…

non-standard thread tolerances in old engines

53/5/1: Chasing threads Regular contributor Andrew Mackey responds to John Burgoyne (53/3/1: Thread standards) in the April/May 2018 Gas Engine Magazine. Andrew writes: I too have run into problems with inconsistencies in threading. When I restored my Charter-Mietz, the threads on the fuel pump, injector, as well as other connections were tapered pipe fittings. Although the OD of the fittings was the same as NPT US pipe, the threads were definitely not the same. They had the same threads per inch, but the taper was very different. The fittings seemed to be ¼ inch. “Normal” ¼-inch pipe in NPT has a thread length of approximately ½ inch to 3/8 inch. The fittings on the C/M engine were about 3/4 inch to 7/8 inch long, and the taper on the threads made their…

Engine collectors are fortunate that Glen Westphal chooses to bring different engines to shows. Like his rare circa-1918 6 hp Emerson-Brantingham U. “About the time I was born in the 1960s,” the Elk River, Minnesota, man says, “my dad, Ronald Westphal, started collecting engines and tractors. I grew up with the engines on our hobby farm, and didn’t really realize that other kids didn’t have engines around, or go to shows, until I got older. That was partly because the shows were done during our three months off in the summer. These days, I’d love to have those three months off to go to all the shows I’d like to attend!” Besides his dad, nobody else in the family was very interested in engines, but that was OK with Glen. “It gave…

the aermotor 2-½ hp general purpose engine

Rural residents of the Texas Hill Country often get their weekly paper a day later than their neighbors living in town, so when Dierre Smith and his wife, Becky, looked at the paper that they just pulled out of the mailbox, they were dismayed to read that an estate sale was already underway to liquidate the worldly possessions of a couple who had lived on a nearby ranch. Dierre and Becky went to the sale as soon as they could, but many of the items had already been snapped up by eager buyers — especially the antique tools and implements that Dierre and Becky found most interesting. Becky is especially interested in old boxes, and she was able to acquire a few wooden ones that appealed to her. When the Smiths…

Bessemer made a wide range of oil field engines. This is an early commercial model which featured the enclosed crankcase. It is interesting that this is the smallest twin-cylinder model built, while the single-cylinder commercial was also built as a 35 hp model. The buyer had his choice! The Bessemer engines were very successful and the firm soon became one of the largest engine builders in the country. Features This engine uses the patented Bessemer “star wheel” igniters operated by twin rocking shafts, as well as hot tubes. Both of these ignition systems were soon phased out in favor of the magneto and spark plug. Bessemer was an advocate of the 2-cycle design and indeed it proved very dependable. The frame was massive and yet provided easy access to parts for adjustment…

too much nitro methane

In 2016 I bought a used Red Wing scale gas engine. Who built it is unknown. It had a set of automobile ignition points for ignition trigger and timing. This, in my opinion, was butt ugly. There was a brass ring with a grove cut in it mounted on the cam gear to open and shut the points. However, poor piston ring sealing made me suspect it had not run much. The brass timing ring on the cam gear prevented the push rod from properly moving back and forth. There was a piece of steel bolted onto the head end of the push rod preventing full stroke return to the cam. The crank and cam gears are plastic and so do not conduct electricity. I decided to remove this brass ring…
