Alright, what the heck is CE?

I take care of my >tools, but any identifying numbers are worn off. The doctor died about four years ago, >so I can't ask him. >The needle is 5/8" long and .02" outer diameter. I unscrewed the needle. It has a blue >plastic flange or sleeve that slips over the hypo tip, just under 3/16" inner diameter, >smooth on the inside. >I grabbed a bottle of Loctite Super Glue (not my usual, but it was in front of me). It's the >water thin stuff I would use on loose tuning pins. The tip of the bottle ends in a step >down to a 3/16" nib that said "yes!" I snapped on the needle and made little sample >drops. >The drops were small enough that they would enable very discrete CAing of tuning or >bridge pins. The "afterdrop" was very tiny and did not drip from the needle tip. Unlike >the nylon tip, it didn't take much pressure to make the drop, so I hope this method will >be less thumb cramping than the nylon tip, which in addition to being sloppy is also a >pain in the thumb. >I usually use Hot Stuff CA, and have a large supply of old caps which have been cut >short when they clogged. Trimming down a bit lower seems to give a good fit on my >one and only needle. >This morning I called a pharmacy and found that needles can be purchased over the >counter in North Carolina. When I finish my "A" tasks for the week, I'll go see what's >available, and maybe can write you a prescription. >The needle would fit perfectly on a Tech-bond CE bottle tip, but might clog because >Tech-bond is somewhat thicker. I will try that when I have more needles. I find CE is >stronger than CA, and am using it fairly often. >I am yet to try this on a piano in the field, so it is just a preliminary report of a first test. >Best wishes, >Ed >-----Original Message----- >>From: Jeannie Grassi <jcgrassi at earthlink.net> >>Sent: Mar 20, 2006 2:18 PM >>To: ed440 at mindspring.com, 'Pianotech List' <pianotech at ptg.org> >>Subject: RE: CA delivery apparatus >> >>Hi Ed, >>What do you mean you "just snapped a thin hypodermic needle onto the tip of >>a 1 ounce bottle of thin CA." ???
