In the last issue
, in a tip about reaming holes in metal to bring them out to a precise diameter, I included an image of a reamer, but the wrong kind. The T-handled type I used as an illustration is mainly used for deburring or manually enlarging a hole in a thin material. The above image is the type of reamer used in machining work.
Also, in that issue, I used the term bolt (which was also used by Izzy Swan, the tipster I was quoting). As my friend Richard Gould pointed out, since the fasteners in question do not require a nut, that are actually screws. Bolts require nuts.
