>Hello Jeannie,

>The needle and hypo were given to me by a doctor in 1992 or 1993. 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

>>Hi Ed,
>>What do you mean you "just snapped a thin hypodermic needle onto the tip of
>>a 1 ounce bottle of thin CA."  ???  How did you do that?  Hypodermic needles
>>come in all sorts of thicknesses.....what are you calling "thin"?  I appear
>>to be stuck on this concept.  (Pun intended!)  Seriously....could you please
>>elaborate?

>>>An artist's brush will solidify and have too much area for pin-point

>>>Two or three fine wires bundled together might work,

>>>Maybe the Moody Drip-o-lator?  (check the archive, it's in there)

>>>Any sure-fire delivery system out there?  Brainstorming welcome.

>>>I'll be suppressing the false beats on a treble bridge tomorrow.
