I have read many interesting articles in these columns about babbitting boxes, but as yet no one seems to have mentioned the important factor of quality in socalled "babbitt." This I consider as important as method in running boxes. Most any handy man around a mill can, after a few attempts, run a very fair box. His method will vary according to conditions, and if his metal is of the usual dark and brittle zinc and lead variety furnished by supply houses under some high sounding name, he soon becomes an expert at the art, because of the altogether too frequent renewals necessary ; and he then "cusses" the machine builders for using babbitt where, he believes, brass alone should have been fitted.

Among other cases of chronic re-babitting, the side-head boxes of our flooring machine were particularly aggravating —wouldn't last over two weeks with the best of care, constant attention, adjusting and oil. I tried every brand of metal on sale in the local market. Some of it would cut out like cheese; others would break all up or work loose in box and pinch and heat. I had the journals turned off and tried the best of oils, and then graphite. I then buncoed the engineer of an English tramp steamer into selling me a 25-pound chunk of imported metal made by Mr. Babbitt himself and stamped with his name and coat of arms —but that lot didn't last long and I couldn't get any more of it.

Finally, I got hold of a catalogue issued by a reliable firm, that sold babbitt metal for just what it was. They had babbitt of five different grades, and stated in catalogue that you "Got just what you paid for." Their 6 cent babbitt wasn't called by any fancy name, and sold at three or four times the price, and their best babbitt was made from the original Babbitt formula and given in catalogue. I got 50 pounds of their best and applied it to side heads at once —and didn't have to run them again for 16 months.

I haven't used a pound of anything else since. It is stamped "Genuine Babbitt," is almost as white as silver, and so tough I had trouble in breaking the bars with an axe. It is very different in appearance from the zinc-and-lead mixtures so common, and will wear like brass, being composed of pure tin, antimony and copper. One of the brasses on the engine crankpin gave out, and I replaced it with a duplicate of this babbitt and run it nearly a year.

For slow-speed bearings most any old stuff will do. Even common solder is a fair article, but for high-speed cutter-heads something with backbone in it is necessary if long, steady runs, and good work are objects. I wrap the cylinder journals with paper, pour metal, paint journals with a thick coat of red lead, cut oil channels, then scrape to a fit as evidenced by turning journals in the box, and then am through with it for two years at least.

Did you ever notice how sand or grit sticks to a cake of soap when you let it fall to the floor? Well, grit sticks in babbitt precisely the same way if it once gets in the box, and will cut the journal full of ridges if not carefully scraped out. Emery wheel arbors, if babbitted, are a good illustration in this instance. Sometimes our oil has sand in it, considerably more than necessary.

By R. E. T.
A great many men think it does not pay them to invest in tools that will help them perform more work in a day, or to have nice, neat looking tools and tool box. When I was working for a firm by the day, turning, or at other machine work, I found it profitable to myself as well as my employers, to provide myself with all the conveniences possible. I know it has been the source of getting me a steady place during dull times in several instances. Many firms furnish tools for their turners. I would much rather work with my own and think it by far the best for all concerned.
