Re: Recork glue

Some makers still used shellac to stick key corks on until very recently. Some sax makers still used shellac for gluing on crook corks - Yamaha still did that until very recently until they switched to using sheet cork instead of tube cork.

Back in the dark ages before contact adhesives became popular, tenon corks were stuck onto the tenons with shellac, hence the deeply grooved tenons which gave shellac something to stick to as sticking hot shellac to cold wood isn't ideal in any way as it almost solidifies on contact.

There are two ways of fitting tenon corks with shellac - either use stick or flake shellac, apply it hot to the tenon slot and use a hot steel spatula to melt it into the grooves and also onto the tenon cork and wrap and stick down as you go, then finish the tenon cork once done.

Another way which will take a lifetime is to use liquid shellac (flake shellac dissolved in alcohol) and stick the tenon corks on with that, but it does mean wrapping the cork strip with string or tape and leaving it for a couple of days for the alcohol to evaporate so the tenon cork is securely attached and can be worked.
