Hi, I have a brass Burke Narrow Bore D and I have decided to grease the O rings.
Do I need to disconnect the fingering tube/bore from the tuning joint when I do this or just disconnect the mouthpiece/tuning slide portion from the tuning joint?
If you do have to disconnect the fingering tube/ bore, how should I do that?
Just the one inside the slide housing. Don’t try to disassemble anything on the body side. The instructions also tell you how to clean the windway with the soap solution to clean & help prevent clogging. Note that you blow through the excess and don’t actually rinse off with water.
My notes I got with my Burke I believe show that you drip the solution into the window and let it drip out the mouthpiece opening. I guess you would call that the windway? Where you blow through?
The directions you linked to look like you drip it into the mouthpiece and out the window.
Does it matter which way it is done? Is there a better way? What is the windway and window?
Got the Burke PDF file.. thanks!
I have a Burke low D and I guess I should try to keep the O rings in shape, as per the document.
But I have some trouble figuring out what the lubricant really is, i.e. how to get hold of the magic stuff. The doc refers to
a) “o’ring lubricant” - where to get that? Online somewhere?
b) “synthetic grease”. No idea what that is - or in what kind of shop I should start looking.
c) “Petroleum jelly” - is that something that is well known in English-speaking countries? Unfortunately I have no idea what it is or where to get it. Are there any alternative names around for this?
I first disconnected the upper bore and lower bore from the tuning joint/slide.
I put light amounts of Vaseline on the O rings on both sides of the tuning joint and inside on the surface of the tuning joint.
I then took a silk microfiber cloth strip and tied it to some paracord and pulled it through the lower bore with 91% isopropyl alcohol on the strip.
I then put the whistle back together and dripped drops of water and Palmolive dish liquid mixed together in a bottle in the opening on the top of the mouthpiece. The drops dripped out of the mouthpiece as I held the whistle upside down.
I then covered the opening on the top of the mouthpiece and blew through the mouthpiece as if I was playing a few times.
