Re: Repadding salt cellar keys

I use natural shellac for cork and leather pads (and in the rare instances I have to use skin pads), but I use hot glue for synthetic or plastic-backed pads as it's molten and sticks to them at a much lower temperature and doesn't melt or distort them.

For key corks and tenon corks I use contact adhesive. And on tenons it helps to machine the grooves or waves completely smooth to achieve full contact on both surfaces as grooves/waves only offer minimal contact with the cork strip. Yes they have more surface area for the adhesive, but contact adhesive is applied in a very thin layer and won't fill in the voids, unless the cork strip is also grooved to mesh perfectly in the grooves which it never is.

In the olden days when shellac was used for tenon corks, the grooves offered a much greater surface area for the shellac to bond to, then the tenon corks were stuck onto the flat surface when the grooves were filled with shellac. Same when using hot glue for tenon corks, but contact adhesive is much better provided it has a smooth surface to bond to.
