I knew I'd seen instructions. I found two of these today. Maybe you guys didn't buy your's from Walter T. Kelley? Here they are (minus the pictures):
"DIRECTIONS FOR USING THE WAX TUBE FASTENER
"Melt the wax or paraffine to be used in a clean tin can or any convenient receptacle. It is advisable to use a tall can with a narrow diameter so that not much wax is required to raise the height sufficiently to fill the tube nearly full.
"DANGER. Wax and paraffine are inflammable. Keep close track of this material when you have it over a burner. To be safe set the can in a pot of boiling water- this will take a little longer, but will be a whole lot safer. Beeswax is better than parafine because the melting point is about 20 degrees higher. Heat your wax to about 190 degrees so that it will sink into the wood and make a firm bond. If you barely melt your wax, it will only make a coating on the wood and will peel off. On the other hand, if you get the wax too hot it will melt holes out of your sheets of foundation.
"When the wax is hot, insert the wax tube and let it remain in the liquid a few minutes to warm up. When ready to use, place your thumb over the small hole in the handle; this will create a vacuum in the top of the tube and prevent it from running out the outlet, holding the frame up-side-down with the sheet of comb foundation in the grooved top bar and slightly inclined. With the wax tube in position, slightly raise the thumb from the hole, allowing the small stream of wax to run into the groove. Move the wax tube the length of the top bar so as to evenly fill up the groove.
"If you have several supers of grooved top bar frames, it will pay you to construct a jig to hold the frames and the foundation along the lines pictured. Any available scrap material can be used. Â¾â€ x2â€ material will make good material, about Â½â€ wider than the frames.
"Make the jig of convenient working height with the 2 legs nailed to the long strips as pictured at about a 15 degree slant, and attach a 3rd. leg to the middle back with a steel hinge or leather strap, so that the leg can be folded flat against the jig for convenient storage, and so that the jig can be adjusted away from vertical 15 to 20 degrees so that the sheets of foundation will lay in position.
"You need forms some smaller than the insides of the frames to hold the frames in place and to support the sheets of foundation, and these can be strips as pictured, or solid pieces, and it is important that the strip or edge next to the sheets will slip into the groove freely. Nail the strips or forms to the long boards for a loose fit, put the frames in position, insert the foundation, and wax in the whole lot of foundation as described above.
