Some time ago I received two gramophone records that were cracked in shipment but the parts were held together with the paper label. As these were single-faced disk records, I used the following method to stick together: I covered the back of one with shellac and laid the two back to back centering the holes with the crack in one running at right angles to the crack in the other. These were placed on a flat surface and a weight set on them. After several hours' drying, I cleaned the surplus shellac out of the holes and played them.
As the needle passed over the cracks the noise was hardly audible. These records have been played for a year and they sound almost as good as new. --Contributed by Marion P. Wheeler, Greenleaf, Oregon.
