Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1904 edition. Excerpt: ...run out in sticks as required. Scrap sheet lead is the best kind for the purpose. If the solder is for blowpipe use, run it into thin strips ten inches long, of sufficient strength to bear its own weight when held straight out, which may be done by using a small ladle with a hole in it at the side; so that when the ladle is tilted and carried forward upon a stone or plate at the same time, the solder flows freely through the hole to whatever thickness is required. Should the solder not show up well, from impurities in the lead or tin, put in a lump of sal-ammoniac and rtir briskly. To know by guess if solder is rightly mixed, pour out a small quantity, the size of a crown piece, to cool; when set and it is bright, having a few prominent spots on it, it is right for use. If it has a frosted appearance put in more lead. If dull and coarse looking put in more tin, or if in sticks take it up, listen while bending it, andif it crackles loudly, put in more lead; if it bends softly put in more tin; but when tough and bright, it will do. To tin Cast Iron.--File the part clean and free from rust, fcc, rub it with sal-ammoniac dipped in water, or make a liquid by dissolving sal-ammoniac in water; it can then be applied with a brush, using the copper-bit at a great heat, which must also have been previously cleaned; when floated well, put on a little resin and sweat the solder well about the part tinning; it will not be a sound job unless the iron is at a good black heat, though it apparently looks so. To tin Wrought Iron Piping, doc.--After filing and cleaning the part properly, use "spirit of salts" (not killed), and when covered well with solder put on a little resin and again sweat it with the soldering iron. This is applicable for...show more
