Susan,
I apologize for misreading your post.
Some uses: extending pedal lyre braces, sculpting new bridge areas, filling gouges on cases, filling bridge pin holes, and of course screw holes. If one wants to color the repair StewMac guitar supply sells colored CA.
To extend a wooden pedal lyre brace: wrap masking tape around one end of the brace leaving a cup of sorts. Put in a level amount of baking soda and then apply several drops of CA. Remove the tape and sand or grind to your desired length. If you want to add a considerable length it works better to build it up. Still only takes about 5 minutes.
To sculpt a bridge area: use baking soda to form the area and apply CA. You may have to build it up, but only takes a few minutes.
To fill bridge pin holes: use pipette to drive baking soda into hole, level, then apply a few drops of CA.
To fill case gouges: fill with baking soda than apply a few drops of CA.
To fill screw holes: fill hole with baking soda using pipette, level, and apply a few drops of CA. When moving an action stack to improve leverage the screw holes need to be filled. Fast and easy with baking soda and CA.
To repair screw holes without redrilling: use pipette to insert some baking soda, use pipette to arrange baking soda around side of hole, apply few drops of CA with pipette.
Wikipedia states airplane propeller pock marks are repaired using baking soda and CA. Propellers are not in my wheelhouse.

Hi, Tim
I don't mix baking soda and white glue. I've never used baking soda. I mix the white glue with CA glue.
Can you describe some of your many uses, and how to do them?
<thanks>

Susan,
Baking soda and CA is nothing new. I first learned about it maybe 15 years ago from piano technicians in Cincinnati using it for bridge repairs (which I've done for fast permanent fixes). For a description of the chemical reaction you can look it up on Wikipedia under CA glue. I know Wikipedia isn't always reliable, but in a pinch it's OK.
Unlike a mixture of baking soda and white glue, this is not easily undone. Many, many uses. I wouldn't be without it.

I'll make some experiments with CA and baking soda, which I haven't tried.
CA with white glue, in a number of minor variations, has worked extremely well for me -- sets up fast, reversible if one doesn't wait very long, non-toxic.
Do you have some theoretical basis for the baking soda with CA? How did you discover it? Any hints about how you use them?

James,
Thank you for your concern about safety. I go a bit farther than what you suggest, but to each his own. I prefer the pipettes I mentioned because they don't need maintenance and the bulb gets "loaded" with liquid. I've tried syringes and they don't have near the control as a pipette for me.
Good luck with your experiments using baking soda and CA glue. I hope you find the combination as effective has everyone else who has used it.

I hope you are using proper safety precautions such as wearing chemical resistant gloves as well as safety glasses.
I use resin syringes when doing CA pin blocks however I got some very good long length applicator tips that attach to the tip of the bottle. They worked quite well. I did see that the company sells glass pipettes. In my opinion they would last longer and be safer as long as the ca does not get on the rubber bulb. After use flush the glass tube with some acetone or nail polish remover
Personally I would use some fast acting epoxy putty mixed by with nitrile gloves for this type of repair especially on a leg plate or a lyre screw hole. I am not sure of the long term life of a CA glue screw hole repair with baking soda. All I know is that CA seems to crystalize when dried.. I may experiment with the baking soda tip on some small holes .
You do not want CA to get in your eyes or on your skin or clothing. A little on the tips of you fingers is not too bad but I had some glue
spill on my pants and it burned a hole in them as well as burned my thigh. Be very careful with CA and read the label and the MDSD
-material data safety data sheet that explains what it is and dangers as well as precautions

Tim,
I agree. I use these things all over the place. Bought a box of 500 for less than $20.
And too, you can reduce the size of the opening by stretching it with a pair of pliers and cutting off the excess. Now the tube is half the diameter it was before. Nice!

I use .5ml pipettes to CA bridge pins with the strings on. When done: empty and trash. I did a bridge yesterday this way pretty much the same as David Love, but using two pipettes. The video from the PTG seems to me to be overkill both technically and environmentally. I also use them to repair stripped screw holes with baking soda and CA. Pipettes have become a vital part of my tool kit.

You can use a 2oz hypo oiler (hypo-25 from pianotek). It has a fine needle applicator and with the water thin CA you can apply it directly (don't put too much CA in the bottle, 1/8" - 1/4" is plenty and with the smaller amount you can control flow better). The needle won't clog during a continuous application and if you want to you can rinse it out with acetone when you're done otherwise you'll never get the needle unclogged once the CA hardens.
Apply to the non string side of the bridge pin and the CA will wick into the pin joint. A small piece of paper towel will wick the excess up very quickly if you apply too much. I've not had to go back and scrape anything.
When stringing I often use this same procedure to either secure the original bridge pins or secure the new ones. Apply the CA on the notch side of the pin and wick off any overflow with a paper towel. I usually do this before I varnish the notches on new bridges.

False beats through out entire tenor and treble section of 7' Kawai grand piano. Want to CA bridge pins with strings in place. Should CA kill tone, can I just back off string and pull up to reinstate clear tone or scrape string with dental tool to break string free. OR must I remove each string from bridge pin before applying CA glue.
Looking for fastest and best solution.
