Pressing out the top of a fine, old English Cello by clamping it into a corrected cast. A cast is made of the sunken/distorted top ….the mold is then scraped to what the arching should be/ had been.Then using a heated sandbag to distribute the pressure…with a little moisture … The clamping pressure will then conform the top to the corrected arching….over a period of many days. Then a breast patch of new wood is fit… then glued in….with a new bass bar fit on top…and the Cello is ready for another generation of string tension strain. its amazing how pliable wood can be….I also get a kick out of using this sandbag…..which I stitched together back in my Moennig days ….and have used countless times since then…….
