ABSTRACT:
A bar mounted chainsaw cutting depth gauge is described on a chain saw cutting bar for selectively covering a length of the chainsaw bar and bar tip. The gauge includes an elongated base sleeve mountable to the chainsaw bar to cover a portion of the chainsaw bar. A fastener releasably and securely mounts the base sleeve to the chainsaw cutting bar. An outer housing is slidably received over the chainsaw bar and base sleeve for sliding movement along the length thereof from a first or extended position wherein the bar tip is encased within the outer housing and a second or retracted position wherein the bar tip is exposed outward from the outer housing. The outer housing includes an outer tip with a slit formed therein for permitting passage of the chainsaw bar therethrough. A spring is operatively mounted between the base sleeve and outer housing to constantly, yieldably bias the outer housing toward the first extended position. A selected depth of cut is determined by either a pin placed between the housing and base sleeve to set a maximum or minimum cutting depth, or a clamp is used to lock the housing at a selected cutting depth.
