To make waterproof glue, add one part of potassium bichromate to fifty parts of glue.

It will harden when exposed to the air and light and be an insoluble liquid.[8] [Footnote 8: For recipes for this and other glues, see Woodcraft, May '07, p.

49.] _General directions for gluing._[9] Before applying glue to the parts to be fastened together, it is a good plan to assemble them temporarily without glue, to see that all the parts fit.

When it is desirable that a certain part, as the panel, in panel construction, should not be glued in place, it is a wise precaution to apply wax, soap, or oil to its edges before insertion.

Since hot glue sets quickly, it is necessary after the glue is applied to get the parts together as soon as possible.
