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. ( KD9VFU ) has updated the project titled SDR dock 1.0.With regard to the spark plugs, they have a 10-40 thread.

And it appears that no CNC was used – even those intake headers and the rotors for the supercharger were hogged out of aluminum using a manual mill.

’s build log is a long series of forum posts, but from what we’ve seen it looks like every part was made by hand with the exception of the fuel injection system. Even the caps for the spark plugs were custom injection molded right in ’s shop. We doubt the local Vespa club would look upon it as legit mod, but we’d love to see it. Nearly three years in the making, behold the raw power and precision of this 1/3-scale V10 engine.Ĭoming in at 125 cubic centimeters displacement, ’s fuel injected masterpiece isn’t too far from the size of some motor scooter engines.
