OH, THAT'S why you got the grinder so cheap!  The angle scale is the most important part!  Better send the whole unit to me for parts, and I will pay you $5 more that what you spent, plus shipping.  Better send the spinner/breaker set too!

I have had a 511A for several years and it has been very reliable.  Also, kind of a 'standard' that others are compared to (e.g. Asian copies, newer models, etc.).  You will find it very useful.

Oregon is usually very good with customer service.  If you call their 800 number and describe what you need, they should be able to help you get a replacement scale I am assuming that it is the one for the vise rotation that you need?).  Note that the screwed on angle scale for the grinder head tilt may or may not agree with the one cast into the main casting.  These are fairly well made tools, and provide good accuracy (repeatable angles), but they are not super precise, aerospace instruments.

You may find that '30 degrees' is not exactly 30 degrees, which is why the calibration part is important.  Mount a new chain in the vise and try to 'match' the angles.  Then adjust your scale accordingly, if you can.  I always check R and L cutters to make sure that they are the same after I do the first one on 'the other side', and make any adjustments necessary.

Congrats on a nice score.

On my grinder the tilt scale on the back side is right on with the scale up under the head at 90 degrees but the farther you get away fro 90 the worse off it is. I don't use it anyway.

The scale on the very front for swinging the vice is right on as long as you don't tilt the vice but I know how much (which way it is off) with the vice tilted.

I would love to send the grinder to you but I bolted it down and welded the base to the beam in my wall, now I would have to send you my whole shed...sorry. Again thanks for all the tips, this is a really great place to spend some time.

With the regular 3/8" chain on the big chainsaws you use the 3/16" width wheel.

With the big .325 chain like Stihl .325 RS, you use the 3/16" width wheel

With the 3/8" Low Profile (PICO) chain you use the 1/8" width wheel. Note that there are .325 chains (Oregon) with essentially the Low Profile cutter and you must use the 1/8" chain on them also.

Bailey's has had some Molemab (Italy) grinding wheels real cheap ($12) but their shipping will eat you up unless you buy several things at once. Molemabs are pretty good.

Chinese wheels like the Timber Tuf on Ebay are awful wobble wheels that have a poorly defined center hole. You can grind a chain with one of these but you have to go slow and be careful. Don't take the wheel off for anything or you will have to dress it round again.

If you want to do rakers, use the 5/16" thick wheel. I do rakers with a file.

I bought a new wheel locally, the one on there was suspect. What I noticed was the old wheel was made in Canada and the new one is from Mexico and is not the truest running wheel I have seen.

Oregon branded wheels may be made in Canada, Mexico, or Italy. I don't know if one is better than the other? I have some Mexican wheels and they did better than Chinese wheels.

Pacific wheel makes some nice grinding wheels. You might find them at Madsens $14.50 + Shipping?
