Make Gas Valve Stems Longer.

" This," writes Mr. Ferguson of Belfast to a leading Auto journal " is an everyday job with us, and our method, which we have found to be most successful, and we feel certain would be interesting to your readers, is as follows : — Braze a piece of tool steel to the end cf the valve stem ; before this has had time to cool, plunge in water to harden it, and grind same to correct length. This makes a splendid job — in fact, better than new, as the end of the valve stem has a perfectly hard surface, and wears much longer. Also there are fewer loose parts, and consequently less wear than in the methods recently suggested.
