Boring Bar: Driven Between Centres, with a Set-Screw Cutter (Yates, 1922)
A home-made boring bar for holes too long for an ordinary boring tool, which would spring. A short, stiff bar runs between the lathe centres, driven by a dog, and carries a hardened tool-steel cutter locked in a cross-hole by a set screw. The work is bolted to the lathe carriage and fed past the turning cutter.
Result: a boring bar, plus the small short-cut bar of Fig. 110.
Source: R. F. Yates, Lathe Work for Beginners (1922), pp. 134-136. Unknown: bar diameter and set-screw size. Picture: Figs. 110-111 of the book.

Turn the bar
Turn the bar
Turn a bar no longer than the job needs; the shorter it is, the less it twists under the cut. Drill both ends for the lathe centres. For short cuts, the small bar of Fig. 110 is 4 to 6 inches long with a round shank and a squared end. Ours: mild steel round bar. Not given: the diameter.

Bore with it
Bore with it
Bolt the work down to the lathe carriage carefully and securely; carriage bolts of several sizes are handy for this. Drive the bar between centres with a dog and feed the carriage. Run very slowly when boring cast iron, and keep the feed light so the bar does not spring.
