Lightweight chainsaw guide bar

A guide bar for guiding a chain of a chainsaw, the guide bar being operably coupled to a housing of the chainsaw, the guide bar comprising:

• a first side plate comprising a first planar inner sidewall and a first planar outer sidewall, the first planar inner and outer sidewalls being spaced apart from each other by a consistent distance over an entire length of the first side plate;
• and
• a second side plate comprising a second planar inner sidewall and a second planar outer sidewall, the second planar inner and outer sidewalls being spaced apart from each other by the consistent distance over an entire length of the second side plate,
• wherein the first side plate and the second side plate extend away from the housing to a nose of the guide bar,
• wherein the first and second planar inner sidewalls face inwardly toward each other and the first and second planar outer sidewalls face outwardly away from each other,
• wherein the first and second planar inner sidewalls each include recessed portions extending toward the first and second planar outer sidewalls at which material of the first and second planar inner sidewalls has been removed,
• wherein the recessed portions extend fully through the first and second side plates,
• wherein the removed material of the recessed portions is uninterrupted away from a perimeter of the first and second side plates, and
• wherein a resin is provided within the recessed portions.

A guide bar for guiding a chain of a chainsaw, the guide bar being operably coupled to a housing of the chainsaw, the guide bar comprising:

• a first side plate defined by a first planar inner member and a first planar outer member, the first planar inner and outer members being spaced apart from each other by a consistent distance over an entire length of the first side plate;
• a second side plate defined by a second planar inner member and a second planar outer member, the second planar inner and outer members being spaced apart from each other by the consistent distance over an entire length of the second side;
• and
• a base plate disposed between the first and second side plates,
• wherein the first and second planar inner members face inwardly toward each other and the first and second planar outer members face outwardly away from each other,
• wherein both the first and second side plates extend away from the housing to a nose of the guide bar,
• wherein the first and second planar inner members each include a recessed portion at which material thereof has been removed such that the recessed portion only partially extends through the first and second side plates to a depth less than the consistent distance between the first and second planar inner members and the first and second planar outer members,
• wherein the base plate further comprises cutout portions, and
• wherein the first and second planar outer members opposite are continuous metallic planar surfaces.
