  • 1.  Syringe for CA Application

    Posted 06-06-2021 16:05
    I had seen somewhere (and of course now I can't find it) where a surgical syringe is recommended for use in applying CA glue to tuning pins on a vertical piano with no need for tilting the piano back...? Anyway, are there any particular syringes that one should use?

    Thanks.

    I don't think I'd use syringes, you can't control the flow with a syringe very well, especially the low viscosity product you'll need.  But you can buy CA application tips here

    The CA will clog the syringe very quickly. In addition to David's recommendation I buy a variety of tips from hobbylinc.com, some extremely slender. These can be cut back as they clog. 

    Then of course don't just throw them away...dump them in a jar of acetone to dissolve the CA. Then (and this is a secret) blow them out with compressed air. Otherwise the residue will simply reclog in no time. I re-use these MANY times thus way. Compressed air is the key.

    Plastic disposable transfer tube-cheap

    I use these for all sorts of CA work. They give great control of the amount dispensed, as in fraction of a drop, and are dirt cheap. They do not clog with CA, at least while using them. If you put one down for a while it might clog, but it doesn't matter, because they are so cheap...just grab another one.

    Maggie Juziell recently wrote about using small tubes of CA with tips on the end to treat pins without tipping the piano.

    Since I have a tilter I use it on all verticals I treat since many of the pins need quite a bit of CA.  Grands do not need much more than protecting the action which you can protect by removing or inserting cardboard or other barrier between the action and bottom of the block.

    As far as syringes I use epoxy syringes from the West System, pouring the CA into a glass jar or shot glass and drawing up the CA into the syringe. I find I have excellent control using the syringe which I eventually toss. Because it is not attacked by the CA the syringe could probably be cleaned with acetone. However I am not sure how the rubber in the syringe will react to the CA.  If you want to use mix cups make sure they are compatible with epoxy. CA will burn a hole in a plastic cup like those used for cough medicine or hobby work.
