Learning to Play and Make Uilleann Pipes

Delrin and Cocobolo Wood Penny Chanter Mod

Curt Garvis documents a modification of David Daye’s Penny Chanter design, using Delrin rod and Cocobolo wood stock to enhance the aesthetics of the stock design.

The use of the Delrin rod drilled exactly to size should eliminate the problem of voids between tone-holes resulting in air-bleed.

Note that metal inside wood can be problematic, but in this case, the wood is probably thick enough to withstand expansion pressures.

It’s a very attractive modification.

    I use the pseudonym Epitomichi for posting on YouTube. I live on a hill overlooking the Tomichi Creek in Gunnison Colorado.

    I don’t know Dirk. Gunnison is quite distant from Boulder, or pretty much anywhere else. I reside in solitude in my mountain sanctuary, learning what I can about Scottish smallpipes and uilleann pipes from the web.

    I think your crimping on your tube bending is caused by insufficient annealing. The brass on the large radius was not soft enough to stretch, but the brass on the small radius was soft enough to bend into a crimp. I heat my brass tubing in the evening so that I can see its color well. I heat the brass to a dim red color — nothing like the bright cherry that heated iron develops. I heat the tube as if it has four sides, which means that I really heat the tube four times. You are right to avoid lead. For small bends sand or ice should be OK. If you get into making 180 degree bends for drones, look into low temperature bismuth alloy. You can find it on eBay.

    When I anneal brass, I don’t worry too much about how it cools. If I don’t have the urge to work it immediately, I let it cool slowly. But, if I need to handle it immediately, I quench it in water or snow. Putting a bend in a tube hardens the brass. If the swan neck undergoes minute bending during playing, that movement will harden the brass. My bender is not as fancy as Davy Stepehenson’s, but I do fasten the brass. I patterned my bender after the one made by Bill Thomas:

    How will the silicone hold up in bag and bellows? I trust the industry tests that predict at least a 30 year lifespan. According to a Dow Chemical web page: “Silicone sealants and adhesives increase the life span of bridges, ships, office buildings, airport runways and highways.” If silicone can do all that, it should also work wonders in bellows.

    I put the leather’s rough side inside bags and bellow. By thinning the silicone with mineral spirits, I get the silicone to infiltrate the leather so it cannot peel off. If I were to put the leather’s top-grain inside, I would look for a liquid vinyl product like the stuff sprayed on leather as a pigment finish.
