Lately, we've been getting some 'returns' with carvers stating a problem with overheating of the bar.
Uniformly, we've found clogged oiler holes, thus dry running, and tight chains.

Are any of you finding this a problem with any particular brand of bars? Do you prefer the larger oiler holes such as GB provides? or does it provide too much oil for carving? (some saws don't have adjustable oil pumps e.g. Makita 5012b.

Cannon oiler holes are probably the smallest, Forrester slightly larger, with GB the largest.

Appreciate your feedback

I always drill and grind a little groove on some of my saws the oil hole will go past the entry on the saw port.

Are you putting the groove in the bar or the saw?

Fine saw dust. Tell them to run a hacksaw blade down the groove of the bar a few times, and blast it our with compressed air. I only use forester bars, I've had problems with the GB bars flaking.

Scotty, I run Cannons on the Husky 338's and the MS200 and don't have any problems at all.

The only problem I have had over the years with oil is the price of it
