In the September issue of GEM, John Broussard has a want ad for information on the Studebaker 9350 aircraft engine. Over the past few months we have corresponded with John in this regard. We must confess that until he brought it up, we had never heard of a Studebaker aircraft engine, nor did we know that they had spent any time in developing one. Apparently, this was a huge 24-cylinder engine capable of something on the order of 5,000 to 7,000 horsepower.
Although aircraft engines aren't the usual fare in GEM (perhaps there aren't many people following this specialty), we too would be interested to hear more about the Studebaker engine. So, if you can shed any light on the 9350, kindly write to John Broussard, 2004 Pinhook Road, Suite C, Box 566, Lafayette, LA 70508.
We recently received some photocopy material from Maynard Peterson, 61 Horseshoe Road, Wilmington, OH 45177. Maynard recently came across a copy of 'Farm Light & Power,' a 1920's guide to farm lighting plants. For example, it illustrates a two-cycle, direct-connected light plant from United Engine Company at Lansing, Michigan. Also illustrated are several models from Radiant Manufacturing Company at Sandusky, Ohio. Perhaps we can eventually incorporate this material with some others so that all our collectors can benefit. Thanks to Mr. Peterson!
Ye olde Reflector hasn't been in recent communication with Ian Stewart (The Olde Machinery Mart Magazine, Australia), but we do hope that plans are moving ahead with the Australian Vintage Machinery Congress '91 set for next year. We plan to attend as a goodwill ambassador from Stemgas Publishing Company. We hear that there are some very interesting collections in Australia, and we have also heard that the Australian collectors are looking forward to the Congress. If you've ever thought about going to Australia, perhaps this might be a good opportunity.
The September GEM carries an interesting article on the Marshall Six-Cylinder tractor (see pages 12 & 13). In an article titled 'Pioneers of Power,' pages 6 6k 7, Bud Motry chronicles some of the significant developments of engine design. Note that the majority of early development was in Europe, not here in the United States. Thus, we see an interesting situation. Although many of our readers have little or no interest in foreign engines or tractors, we perceive a subtle shift by many others. Ten years ago, hardly anyone gave thought to owning a foreign-made vintage engine or tractor. Now we see numerous examples at our shows. The interesting part is that good old hindsight gets busy. In many of the foreign designs we see many features not usually found on American-made engines, and vice-versa. The irony is that occasionally we see a feature propounded as a radically new design, when in fact, someone here or in Europe came up with the idea ages ago.

Max F. Homfeld, RR 2, Box 697, St. Michaels, MD 21663 offers the following information in response to the F-12 Farmall article appearing in the July 1990 GEM:
'Mark Maikshilo had a very interesting article in the July 1990 GEM entitled '1935 F-12 Farmall.' In it he mentioned 'freeze plugs'. He shares a very common misconception as to the purpose of the plugs one sees in cooling jackets. The proper name for them is 'core plugs' and I want to tell why they are there in many engines.
The outside shape of a cylinder block or cylinder head is cast in green sand, which is common foundry sand. Foundry sand is formulated differently in different foundries, but it contains beach sand, coal dust, and other ingredients. Just the right amount of moisture is used so that it packs well around the pattern.
Interior surfaces are formed by cores. Core sand is beach sand mixed with an oil that will harden when the mixture is baked in an oven. The traditional oil was linseed oil, but synthetics are used today. These dry (baked) cores are rigid. They are set into the mold to form water jackets, cylinders, etc. The pattern provides core prints in the green sand to locate and support the cores. Very often, the core supports must go right through the wall of the cylinder block or head. The holes in the castings are later plugged with a core plug.
The Farmall F-12 has separate replaceable cylinder sleeves so a cooling jacket core is not needed and there are no core plugs. So, please don't use the term freeze plugs; use core plug instead.
Having always been intrigued by the performance of a sawmill, I was prompted to build a model. The model shown in the above photo was built mostly from odds and ends, even including an old Model T fan pulley. I power it with an 8 HP Briggs & Stratton engine. Now that the bugs are out, it saws very accurately. Glenn Shoop, 13918 Collins Rd., Collins, OH 44826.
