Popular Mechanics, February, 1994-An article called “Peewee Power” covers 3 full pages of color in this popular consumer magazine. But this article shows more photos of the engines in production, and during the machining process. R/C Model Cars, June, 1990-This article also features Butch Leal’s Pro Stock Dragster in 1/4 scale. Hot Rod Magazine, May, 1990-Another article which shows details of a Conley V-8 powered model of Butch Leal’s Pro Stock dragster in 1/4 scale. Hot Rod Magazine, March, 1984-This 3-page article shows photos of the early V-8 engine in production. Tools are good, more tools are better.”Ĭlick on links for a full PDF of the article. On the topic, Gary said, “I guess that I am really a ‘tool horse’. Gary has been designing and building model engines for about 30 years, and during that time he’s acquired many tools and machines. As you can see, there are a lot of items needed to make a small manufacturing facility operational. When it comes to saws, he’s never even attempted to keep track of the number and kinds in his shop. Gary also has a vast array of hand and power tools, plus things like wrenches, sockets, files clamps, pliers, cutters, screw drivers, etc. 016” to 1.25″, carbide cutters to 5″, taps and dies from 0-80 to over 1”, and more. A second rolling tool box contains: drills of every size and various lengths, reamers, end mills from. These include, but are not limited to: micrometers measuring up to 12”, a digital clinometer for measuring exact angles, setting gauges, dial indicators of every description and size, digital calipers, gauge blocks, pin gauges to 1″, bore gauges, and more. Gary jokingly said he was working on a way to program it to make his breakfast.Īlong with these machines, Gary’s shop also contains many others not pictures here, as well as a bevy of measuring equipment. This machine does about everything in the way of machining. Once he started using the “thread forming” tap, he was able to tap 234 holes with just one tap. No matter how he changed the feed and speed rate, he kept breaking a lot of taps. A good example of this is when he had to tap some 2-56 holes in the 303 cast stainless steel that was used for the differential housing. This not only gives a stronger thread, but also allows him to tap some very difficult metal. Simply stated, this is when the metal is not cut with a tap, but rather the metal is displaced and “formed” into the shape of a thread. More and more of his tapping operations are using what is call “thread forming”. Gary taps a lot of 2-56 holes with very little breakage. Once the depth has been achieved, the spindle stops instantly, then reverses and retracts at the same feed rate. This machine also has what is called “ridged tapping,” which means the tap is fed into a pre-drilled hole at a pre-determined rate and depth. It simply means that each part is “identical.” The interchangeability of parts is absolutely critical. He says he cannot overemphasize the importance and the need for a machine with this kind of accuracy. Once the machine is programmed, Gary can literally walk away and do other work while the machine does almost everything. This is extremely fast, and if you aren’t careful, or there is a mistake in the program, it can get ugly very fast. It also has a “rapid” movement of about 975 inches per minute. Chip to chip refers to the amount of time needed from when the tool stops machining, retracts, changes tools, then rapids (moves) to the next operation. 0001, and has a “chip to chip” time of about 5 seconds. The stand was finished and wired, including a radiator, fuel tank, and powder painted steel frame.ĬNC Machining Center -This machine will repeat to. It included a custom hardwood base that concealed the battery and electrical components. A transmission with forward-neutral-reverse was expected in the near future, but updates are unknown. Additionally, a self-contained engine test stand was also available. Options include: cast stainless steel exhaust manifolds (plain or polished), painted valve covers and intake manifold, supercharger, and high duration camshaft. The standard engine includes “Zoomie” style exhaust pipes. Instead it has a 12 volt electric motor that is a fundamental part of the engine. It can be activated manually or via the transmitter on a remote control. It doesn’t have handheld electric motors, or something that fits in a box below the engine. As always, the new Stinger 609 V-8 will have an electric starter as standard equipment. With regard to the spark plugs, they have a 10-40 thread.
