Oregon 33SL

[jellyroll]

Got a loop of this that needs sharpened. I am using a oregon 511A sharpener and don't see the angles listed in the book.

Is it full square chisel chain? Might be the reason

it is round ground square tooth chisel.
most Oregon chain of that type is 25* , however if loop is old enough it may 30* from factory. But Oregon says you can change it to 25*

I did my 33 at 30 myself. Preference. You can change it to whatever you like best. Nothing set in stone.

It is .325 semi chisel but looks nothing like modern .325 oregon chain it has bumper drive links.

It has bumper tie straps. 33LG is the same but normal tie straps. It is low profile .325 the teeth are shorter and stick up less off the bar than 20lpx or lgx that replaced it. Chisel type cutters. 11/64 file called for and that barely fits when new.

33 is the series number of that chain. There were different cutter, versions. Chisel, semi chisel etc. Technically Oregon specs and sells a 4.5mm file for that series of lower profile cutters. (very close to 11/64) A 1/8" grinding wheel is not optimal for those cutters, but a 3/16" wheel is too big.
