A THIRD HAND ON THE DRILL.

WHEN we were dealing with the exhibits at the British Industries Fair (Birmingham section) comment was made upon the usefulness of an automatic feed drilling machine which was there exhibited by L. W. Young and Co., Ltd., Wellington Buildings, Strand, Liverpool.
We have now had an opportunity of conducting some practical experiments with the drill—which, of course, *as not possible when inspecting it at the Exhibition—and we have confirmed our conclusion that it should be an extremely useful tool in any works where holes a small diameter have to be bored, that is to say, holes up to in. The accompanying photograph was taken during the course of an' effort to drill through a piece of spring steel, which effort was perfectly successful,because the drill does not tend to run away at starting and, the pressure being applied automatically, is so properly proportioned to the needs that there is no tendency for the drill to he broken.
Through in. mild steel the drill cut its way well inside of 40 secs. The amount of pressure which is applied by the balls, through the leverage afforded by the system of feed, is very great, arising, we are told, with a 31-to-1 gear, to about 2 cwt. This pressure is attained at a comfortable hand speed.
Thus, the advantages offered by this drill are: First, the equivalent of a third hand; secondly, pressure exactly equivalent to what the work demands—for if the resistance becomes too great, the pressure is automatically eased off ; thirdly, the extreme, ease of operation ; and, fourthly, the 'adaptability to requirements entailed by the shape a the work being operated upon, for the drill stock can be placed at any height on the vertical steel pillar, and it can be swung to any angle ; thus the drill can be screwed down to a bench, and the drill stock swung round so that the drill is clear of the base plate and over, for instance, a vice fastened to the bench at its side. •
It was interesting to find that it was practical to tap holes withthis appliance.
The drill is priced at 50s., and is a thoroughly well-made appliance.
