As a 1960s Clarinet player, I came in contact with “Woodwind Bore Oil”.
This oil was recommened, to prevent cracks in the wood of the clarinet, by preventing the wood from absorbing moisture. In the case of long term storage, or exposure to hot, dry environments, the oil prevented the wood from drying out I found out later, that alot of the commercial formulas, which are usualy based on Almond oil, had/have additional Petroleum Distillates which attack the resin in the Hardwood. The rationale for this petroleum additive, is mainly for rapid oil penetration into the wood (this is due to the oil being “thinned out”), and as a preservative for the oil, to increase its shelf life.
In 1973, I became aware of use of “Sweet Oil” in the Northumbrian Piping scene, for oiling the leather pads on the chanter keys.
Sweet Oil can be both clarified Olive oil, and clarified Almond oil, it is available in small bottles, at a price, from the Chemist / Pharmacy.
The process of clarification is where the oil is heated to just below its burn point and as the solids in the oil rise to the top of the oil, they are skimmed off, leaving a “clear”, very tranparent oil. This clarified oil does have a long shelf life, as the solids are what “goes rancid” in the oil.
I have bought clarified Almond oil in cheap, large bottles, from Indian grocers along University Avenue in Berkeley, California. My friend Ted Anderson (the"reed guru") prefers Cold Pressed Walnut oil with some vitamin E added to prevent oxidation (a large part of being rancid). The Walnut oil drys out quickly and leaves a “skin” of sorts on top of the wood. Oiling the wood does protect it, but too much oil (of any kind), in a sort period of application, is bad for resinous Hardwood. So sayth Ted, and I believe him, as he has read more books and articles on this subject, so I HAVE limited my oiling to twice a year, on average.
A further note about petroleum additives in Leather preparations, which I avoid, such as “Lexol”. This stuff made all my stitches drop out of my large, Tayloresque Bellows. I had to redo the sewing, very costly… Neatsfoot Oil “Compound”, which is “cut” with 10 weight motor oil. Neatsfoot is derived from cow hooves, and is better in its “pure” form. Long lists of Mink oil, Lanolin, Glycerin, and etc. Read the labels and don’t use the petroleum compounds on your leather, so sayth Sean (Amen).
I prefer an light oil finish on my Hardwood, versus French polish, which is attacked by the acidic oil on all our skins, and requires frequent wiping off, to maintain it. There’s Shellac, which I have used on some of my soft, fruit wood (non UP) chanters, to prevent scratches, etc.
My advice is OIL all the way!
Don’t let your chanters crrrrrack! Sean Folsom
