The Deagan Project: Part II









Escutcheon Pins, Washers and Isolators
Most of the pins were bent but easily straightened. Just tapping them on a bench vise did the job. I replaced the one wood screw with a sheet metal screw for the lost pin.
For the washers I used silicon caulking compound. Earlier this year I tried making sheets of silicon by applying caulk onto a plastic sheet protector. I placed another sheet on top and rolled it out to the desired thickness. After it cured I took a hole punch for the outside diameter of the size that I needed. The smallest punch was used for the center hole for the pin.


In the past I used catheter material for the isolators but when I went to a medical supply store to find the size that I needed I was asked for my doctor's prescription. A prescription?.....Are they afraid that I'm going to insert a piece of plastic into parts of my body just for the...….never mind. OK, so nix the catheter tubes. Since I was working with silicon I tried a different approach.
I took a length of wire that was 2 or 3 gauges smaller than the pins and inserted them into the tube of caulk. I did this twice more for a total of 3 coats to increase the thickness of the final tube. After it cured I used a razor knife to cut around the wire and pulled off each section. Since the hole from the wire was slightly smaller in diameter than the pin, when installed it expanded to the overall diameter that I needed.


The bars were done, the pins, washers and isolators were finished. I had only the felt rails to replace.

    perhaps they thought you were really strange? Made me smile:)

The Amadinda

  The Amadinda is an African xylophone originally made from slabs of wood or even large sticks, with or without gourds for resonators. There was no reason for this project other than to see if I could make a simple mallet instrument. The box was made from plywood (which also acted as the resonators) and the bars were made from maple.  Since this was to be a true xylophone, the bars were all of equal width. Tuning was done by cutting the bars to different lengths and removing material from the bottom. Using a router I created a sort of 'stepped pyramid' instead of the traditional arc cut found on marimba or xylophone bars.  Cutting the underside is not only for tuning but it focuses the pitch and creates the characteristic overtones of the instrument. Since I wanted to play this with other 'Western' instruments, I chose to use a pentatonic scale of 2 2/5 octaves (C#,D#,F#,G#,A#,C#,D#,F#,G#,A#,C#,D#). Two people sit on either side of the instrument and strike the ends of ...

La Caverna del oro

 One of our first backpacking trips in Colorado was in the Sangre de Christo Mountains. One mountain in particular drew our attention. Marble Mountain was the location of a famous story of a Spanish cave of gold. There are many places on the web that tell this story better than I could, suffice it to say that we wanted to locate it and see the iconic 'Maltese Cross' located at it's entrance.  In 1974 after I got out of the Army we invited some friends to join us on this trip. We parked our car at the trailhead in the Wet Mountain Valley and backpacked up Marble Mountain to 12,000 feet. In one of the culverts we found the entrance to the cave. Maltese Cross at the Caverna del oro It turned out to be a real thing. The large red cross was still visible after 400 yrs. According to legend the Spanish put it there in the 1600's. I did have the courage to crawl into it but only a few feet. After about 10 feet there is a vertical shaft that drops about 750 feet!  The Cross is v...

Matte Black

 I just realized that this sounds like a 'James Bond' type spy thriller. Actually it involves my attempts to produce a non-reflective finish for so many of my aluminum projects. Powder coating and anodizing are the typical processes to produce this finish but they are expensive or require car battery chargers and caustic chemicals for the DIYers.  I've tried a flat black paint using etching preps etc. but they all resulted in the paint chipping off quickly when tossed around and hitting other things in an accessory case. Since I use a 2 part epoxy to connect the parts of the Nickster together with perfect results, I thought about using this as a bass coat for the paint (see my Nickster Commemorative post). This result had promise but the finish became glossy even though I used the matte black paint in the mixture.  I came up with this idea from an accident. After the epoxy/paint mixture experiment I left some of the mixture out and some of the paint had dripped on the mix...
