Re: New Oregon Grinders
« on: August 09, 2015, 12:59:26 am »
Tried the Oregon 310 grinder side-by-side with a  similar looking mini-grinder, and a full sized 511A grinder, sharpening a bunch of .325 pitch, 67 drive link STIHL chains.  Obviously, the smaller grinders could not compete with the 511A in terms of power or speed.  The fixed head tilt angle also made it hard to match the existing angles on the chains, so I had to take off a little more metal - not an issue if someone only uses these grinders.

Light duty.  Simple to set up, easy to use, quiet (like a sewing machine motor), takes up very little space.  Could be OK for light touch ups on smaller gauge chains. Or by someone who sharpens infrequently, has a light touch, and a little patience.

Advantages of the Oregon 310 (right) over my 'Infinity' brand 'HF-style' grinder (left):
- cast aluminum base, instead of plastic;
- larger, more effective chain holding dog on the vise;
- accessible motor brushes;
- came with additional 3/16" grinding wheel, dressing brick, wheel template, extra motor brushes;
- better (but not perfect) owner's manual;
- Oregon support (if needed).

All things equal, I would choose the Oregon over the generic grinder, if I was picking a mini-grinder. But the generic HF grinders are often available for about half the price. Some of this difference can be attributed to the advantages noted. Maybe some of this difference will dampen out as more vendors and discounters start carrying the 310?

Will continue to play with these, and maybe try them for portable use,etc.
