In this instruction set you will learn how to make Dm11 4/2 wind-chimes.

Step 1: Gather Materials

Material Needed

15' Copper Pipe
Heavy Metal Hoop, (inside diameter of 20")
Heavy nylon String

Tools Needed

Saw (Band Saw Recommended)
Drill (Drill Press Recommended)
Measuring tape
Pencil
Grinder
Copper Reamer
Sandpaper

Step 2: Measure and Make Cuts

Measure and cut your copper pipe to match the dimensions in picture. Using a reamer or grinder, deburr the sharp edges left from the cuts. Leave an extra 1/8th” on each chime to allow for fine tuning. Check the tone of the chime by striking it next to a chromatic tuner (you can get one as an app on your phone.) Grind away excess material slowly to reach the tones specified in picture.

Step 3: Drill Hang Points

Using the dimensions specified in [Figure 1], drill the hang points so that 22.4% of the pipe is left above the top of the drilled hole. Be precise! Using your preferred tool, deburr the rough edges.

Step 4: Measure Chord Lengths

Multiply the radius of the rings inside diameter by 0.8678 and cut a piece of nylon string to this length.

Step 5: Divide Ring in to 7 Equal Sections

Using your measured nylon string, mark chord lengths along the inside diameter of your rings as shown above. Continue marking until you come full circle (pun intended) to your original reference point.

Step 6: Hang Chimes

Thread some nylon string through your chimes starting with the longest. Using your rings reference points, suspend the chimes one by one. Make sure the bottom of each chime is level with the others.

Step 7: Play

You’ve just made a set of chimes tuned to dm11 in second inversion. Aren’t you fancy? Smack them around a bit and enjoy deep rich tones. Or engineer a sail and a striker to have the wind do the work for you!
