The high compression cylinder head chambers on all Packard oars are milled out
on this machine. Most manufacturers do not go to the expense of this operation,
merely leaving this compression chamber in its rough state as when cast. Nevertheless,
this final finish on all Packard motors equalizes the compression in each
cylinder and also minimizes the accumulation of carbon because of the smooth surfaces
obtained by this operation. The size of each combustion chamber is checked
for accuracy by testing the volume capacity with alcohol (plus or minus 5c.c.) and
must come within negligible limits.
