EMG-6 "Shop Notes" June 2017

"EMG-6 Shop Notes" is a day-to-day accounting of what's going on in the shop with the EMG-6 Electric Motor Glider.

June 2, 2017 We begin the month of June at a frenetic pace. This is our last full month of work that were able to do before we start the countdown for the trip to Oshkosh. The schedule appears to be very tight. Prototype number 3 has to undergo a complete series of flight tests and documentation. We have a large number of parts that still have to be built and sent to customers this month. And our top-secret project of the month is a new electric motor for prototype number 2. More information on that if it materializes will be forthcoming.

We are currently prepping the Polini 252 get ready to run with the new drive system installed. All of this system is now complete and ready for operational tests. We still have a few other things to complete on the aircraft before we can run the engine. The electrical system and starter system has all been hooked up. The co…

Bending Sheet Metal (Part 2) Sport Aviation / Experimenter "Technically Speaking" Article May 2017

Bending Sheet Metal  (Part 2) In part one of this article we discussed, in depth, the theory and the process for developing a flat layout for manufacturing a sheet-metal part. In this article, we will take it to the next step: the practical process of converting the flat layout to a bent sheet-metal part. The tool that we use for bending sheet-metal is called a “brake.” There are several different types of brakes.  A “press brake”, commonly found in manufacturing environments, uses a vertical positioned die bending the sheet-metal over a stationary “V” block.  A “cornice” brake, which has a solid clamping bar the full width of the brake, is limited to simple straight bends. And the “box and pan” brake. The box and pan brake is sometimes referred to as a finger brake because of its individual fingers which can be configured in a nearly unlimited fashion to make some of the most complex sheet-metal parts. If you are interested in purchasing a sheet-metal brake for building experimental…

Bending Sheet Metal (Part 1) Sport Aviation / Experimenter "Technically Speaking" Article April 2017

Bending Sheet Metal (Part 1)
We are often surprised by the number of aircraft builders who seem to be intimidated by the process of calculating bend allowance, setback, and simply creating a flat layout for bending a simple part. In this article we are going to back up a bit, and provide some of the theory necessary to understanding how we go about the process of converting a flat piece of sheet metal into a complex sheet metal component. Learning to accurately layout and bend sheet-metal is a very useful exercise. Once you have mastered the process, you will find that it not only saves a great deal of time, but also can save you a great deal of wasted material.
To start with, let’s examine some of the properties of aluminum sheet metal used in aircraft. The two most common alloys of aluminum used in the experimental aircraft world are, 6061 T6, and 2024 T-3. 6061 is one of the least expensive and most versatile of the heat-treatable aluminum alloys. 6061 T6 has a tensile strength of…

Bing 64 (CV) Carburetor Part 3 (Idle Circuit) Sport Aviation / Experimenter "Technically Speaking" Article March 2017

Bing 64 (CV) Carburetor Part 3  (Idle Circuit)
In Part 2 of this article, we talked about the starting carburetor (choke) system. We can run the engine at lower RPM settings only on the choke system, but as soon as we reset the choke system to the off position, the engine is now running on the idle circuit only. We often use this as a troubleshooting exercise. If the engine runs with the choke partially on, but dies as the choke is placed in the off position, it is an indication that the idle circuit is the culprit. It is absolutely essential that the idle circuit be set up and functioning properly. We use the idle circuit on every flight, and it is a surprisingly important system within the carburetor. Aside from the practical aspects of having a properly operating idle circuit, there are many correlations with the idle circuit malfunctioning and other engine problems, ranging from increased maintenance to engine stoppage and even engine failure.
