Ireamera of very high clatta design in
jan effort to overcome thia difficulty.

jas all mechanics of experience know,
. a reamer will follow a hole, and can,
(in no sense of the word, be depended
lonon to accurately atruiirhten a hole
j which has been bored out.
"The action of the reamer is to take
its heaviest cut where the resistance.
'due to ribbing or construction of the
block, is greatest, and to crowd the
'cylinder wall at the hard spots.
I Where the hard spots occur there will
I be a projection into the cylinder bore,
'and where the greatest resistance to
jibe cut occurs there will be a hol
Ilow spot. Therefore neither pistons

"While possibly a little better than
the first method, it has the same dif
ficulties and disadvantages, inasmuch
as the broach will follow the bored
hole. 'While to, perhaps, a. less ex-t..il-
Ihun h i-nmer. still the inaecur-

j advantage in that at the point where
the hard spots occur a tremendous
strain is put upon the cylinder wall.

'The operation of grinding is por-1

The machine is constructed of a '
very heavy base on which is mount-1

mounted an adjustable and universal
angle plate with parallels which nc-

On the head of the machine is a grind

sleeves. These sleeves are both ma
chined eccentrically to each other and
provided with an adjustment regulat-

nothing to a desired amount. Extend
ing from the inner eccentric sleeve is
a main or spindle housing, in which is
mounted a shaft and bearings. To the
front end of this is attached the grind
