Keeping Busy! One Collector's Trio of Gas Engine Restoration Projects
It has been quite some time since I last wrote in Gas Engine Magazine about some of my projects, so here is some information about three projects I recently completed.
The first project was the restoration of an 8 HP 2-cylinder Cushman engine. This gas engine was for sale at a show I went to several years ago. The missing parts convinced me to pass on buying it, but a friend of mine, Alex Chunn, did buy it. Over the next few years, he did a lot of the machine work and rounded up most of the missing parts needed to complete the engine.
One day, Alex asked me if I would be interested in buying it from him since I already own a 4 HP Cushman. He offered it to me for a price much less than he had invested in it. I brought it home in boxes and cans as it was completely disassembled.
To see what I had and what I needed to complete the project, I laid out all of the parts. There was no sub-base so this was the first thing I built. I also noticed that it didn’t have the long crankshaft and clutch assembly like I thought it should. I’m not sure if it came from the factory that way or if someone cut it down. If someone did cut it down they did a very good job. There are no saw marks and there is a centering hole in the end of the crankshaft for mounting in a lathe.
I loosely assembled the crankcase to see where everything went and in what order since I did not take it apart. Then I made all new gaskets and painted the parts.
Next, I built a cart for it and the tank-type radiator, and refinished an old wooden box to house the battery and buzz coils. It runs pretty well but still has a few gremlins that need to be worked out.
The next project I worked on was the refurbishment of a 6 HP Witte that I purchased from a friend, George Farquhar. When I first saw the engine I knew I had to have it, but it took about five years before George agreed to sell it to me.
This engine runs on a battery and buzz coil. It was very difficult to start when I brought it home so I took it apart completely to check it out. It was in pretty good shape but needed some work.
After making the necessary repairs and giving it a good cleaning I painted all the parts and reassembled the engine. With a little fine tuning it starts and runs very well now.
Line Shaft Display
The final project I’d like to mention is a line shaft display. I’ve built one before and wrote about it in the June/July 2000 issue of Gas Engine Magazine, but because of its size and weight I decided to sell it. After it was gone, I decided to start collecting parts to build another one on a smaller scale, and I completed it March 2006.
On my shop floor, I laid out all of the pieces to determine what length and width the cart would need to be. I then built the cart and line shaft A-frame.
After arranging all the equipment on the deck, I fastened down the pieces.
My next task was to find pulleys and belts of the proper size and length to run everything. The display is powered by a model AEN Wisconsin engine, and I made a belt tightener clutch to disengage the line shaft for easier starting.
The equipment consists of a lens polisher, drill press, air compressor, bench grinder, metal turning lathe, gas torch, vice and riveting tool. It gets a lot of attention at shows because of all the moving parts.
I would like to thank George and Alex for the privilege of being able to buy these engines and add them to my collection.
