This big 32 HP Oil Well Supply Co. engine is "definitely the last piece of junk to be hauled onto the property," according to my wife.

About two years ago, my 15 HP Reid fell into the same category. One of my wife’s favorite questions is, “How many engines do you need?”

My collection consists of 25 engines, two of which have appeared on the front cover of Gas Engine Magazine (3/4 HP Briggs & Stratton, April 2004, and 6 HP IHC Model M, August 1997).

The Oil Well Supply is the latest addition to my collection. This type engine replaced the old hot tube, babbitt-bearing engines and was made primarily for the oil fields. It has one extra-heavy-duty flywheel along with a twin disc clutch on the opposite shaft. It also has an enclosed crankcase with Timken roller bearings on the crankshaft. The engine has a bore and stroke of 8 inches by 8 inches. It runs between 400 and 750 RPM and has an electric start, which means no more hand cracking.

Tips for the common man
I am sharing my comments, tips and photos for the average gas engine enthusiast. Don’t get me wrong – I enjoy very much seeing the rare, one-of-a-kind and very expensive engines on the front cover of GEM. I also enjoy the stories and detail showing how they use all sorts of boring tools, lathes and mills to reproduce parts, all of which are out of reach for the average collector. But this article reflects how you can collect, restore and be able to say when it is finished, “I did it all.”
