Chainsaw Repair

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.
