Note that changing this selection does not convert the input values Imperial (☏ for temperature, feet/sec for speed, Metric (☌ for temperature, meters/sec for speed, cm for measurements) If you need to convert drill bit sizes to inches or millimeters, check out the Drill Bit Conversion Table (opens in a new window).īy Edward Kort, with user-interface improvements by Clint Goss.They will get overwritten when you click the Don't enter values in the yellow boxes.Remember that mid-range flutes are in octave 4 (C 4, which is fairly low for a Native American flute, up to B 4, which is rather high for a Native American flute).To see how they effect the results in the yellow boxes. You can begin to learn this tool by changing various values in the white boxes and clicking After setting the three parameters shown in green, click theīutton and look over the results show in the yellow boxes.This should get you started for a flute with no direction holes. They control the key of the flute you are crafting, your Inside bore diameter, and the wall thickness at the finger holes. Set the three parameters shown in green below.Here are some suggestions for getting started: Then, if you are not up for diving into the Quick Walkthrough or Some Details sections, Each step provides descriptions and explanations of the inputs on that page.
DA CALCULATION TOOL SERIES
The guided version is composed of a series of eight steps, each on their own page, that helps you set the most important inputs to this NAFlutomat tool. It was developed in August 2014 as a kinder, gentler approach to this sometimes-daunting design tool for flute-crafting. If you are new to NAFlutomat, I suggest beginning with the Guided Version of NAFlutomat. In short: You may find this tool a useful starting point.Īlso, please consider other (less “equation-based”) approaches to flute design on the Finger Hole Placement page. However, the “rather complex equations” used in this tool do not account for pertubations in the size and shape of the flute, the special considerations and limitations on finger hole position or size, or (in particular) the sound that you are trying to achieve. It is typically possible to construct a well-tuned flute by using the results of this tool and then careful tuning of the flute (see the Basic-Six, Basic-Five, and Bob Grealish tuning methods). While these equations provide can provide a “reasonable” first approximation for these parameters, they should be considered a starting point. Note that this tool attempts to predict the best bore length, finger hole locations, and other output parameters using a set of rather complex equations. The basic strategy is to provide inputs such as the key of the flute, the bore diameter, wall thickness, finger hole size, and many other parmeters you will be using, and this tool suggests design parameters such as the length of the sound chamber and the location of the finger holes. This page provides a tool for designing Native American flutes. NAFlutomat - Native American Flute Design Tool
