"MIGHTY MIDGET"
ANGLE DRESSER
Chatter Resistant - Spring Loaded

The hardened, spring loaded, entirely enclosed slide moves in a honed slide-
block that is easily adjusted for wear.

The spring loading puts a constant light load on the slide that is desirable for
accurate work.

The base angle plate is a heavy, precision ground alloy-iron casting, square
on all side to an accuracy of .0002" per inch.

The slide block pivots on a hardened and ground pivot-screw, with a sealed
ball thrust bearing, locking into a hardened nut.

Diamond and handle can be interchanged for convenience of operation.
