The usual method of finishing a crankshaft bearing is to use a hand lap while the
shaft is rotating in a lathe. In the Packard factory the idea illustrated in this
picture was originated to hone to size and to correct out-of-roundness and taper
on Packard crankshafts - again to insure and assure your customer's investment.
Packard has about $60,000 invested in a sufficient quantity of these machines to
keep up with present-day production. Time saved by machine over old hand method
approximately 40 minutes per unit.

After the cylinders are bored and reamed to size, the honing machine puts on the
final velvet-like finish, so necessary today in the use of high compression motors
which demand such.a small clearance between cylinder and piston. Cylinder grinding
so commonly used formerly, is now obsolete. This machine works to an accuracy
of one five-thousandths inch and is infallible in its operation and precision.
