The hole should be bored slightly less than the finish size to allow for reaming.
Babbitt metal is also worked dry, ordinarily, although kerosene or turpentine is sometimes used when boring or reaming.
Small holes are often finished in the lathe by drilling and reaming without the use of a boring tool.
Fig. 11 shows how a taper hole is bored in an engine piston-head, preparatory to reaming.
The lathe is run very slowly for reaming and the reamer is fed into the work by feeding out the tailstock spindle.
In reaming, a hole is drilled about 1⁄32 inch smaller than is required, and is enlarged with a cutting tool known as the reamer.
It is also a well known fact that the process of reaming by hand is not a difficult or a slow one.
Young Lieutenant Blood was to his feet holding a reaming glass high as his head.
measure of paper, mid-14c., from Old French reyme, from Spanish resma, from Arabic rizmah "bundle" (of paper), from rasama "collect into a bundle." The Moors brought manufacture of cotton paper to Spain.
Early variant rym (late 15c.) suggests a Dutch influence (cf. Dutch riem), probably borrowed from Spanish during the time of Hapsburg control of Holland. For ordinary writing paper, 20 quires of 24 sheets each, or 480 sheets; often 500 or more to allow for waste; slightly different numbers for drawing or printing paper.
"cream" (obsolete), Old English ream, from Proto-Germanic *raumoz (cf. Middle Dutch and Dutch room, German Rahm), of uncertain origin.
"to enlarge a hole," 1815, probably a southwest England dialectal survival from Middle English reme "to make room, open up," from Old English ryman "widen, extend, enlarge," from Proto-Germanic *rumijanan (cf. Old Saxon rumian, Old Norse ryma, Old Frisian rema, Old High German rumen "to make room, widen"), from *rumaz "spacious" (see room (n.)). Slang meaning "to cheat, swindle" first recorded 1914; anal sex sense is from 1942. To ream (someone) out "scold, reprimand" is recorded from 1950.
