Oregon 551462 grinder

[Locoweed]

I'm still learning how to properly use this this thing & I noticed that the chain stop tended to raise the link when pulling the chain back against it. So I happened to remember that the Stihl USG grinder had a different stop on it. Turns out there is a good reason IMHO.

At first I thought is was because the back of the tooth on Stihl 325x063 has a angle on it.



So I dragged out a link of Carlton.


Hmm, guess again.

So I went to the Stihl site & looked at their grinder & decided to try something like theirs. One piece of 3/8 scrap & some hand tools created this. Crude maybe, but effective.





Here is the original.



& mine. Longer spring & a spacer needed.


Was this causing a problem?? Is it happening to the non hydraulic grinders?? Am I anal retentive?? Probably. Even if it fixed a non problem I think it is better than the original.

interesting experiment, chains do occasionally move up as you close the vice making that cutter non-uniform. i'd like to see that stop with a very short cutter that has been sharpened many times. your wheel may hit the stop. happens some times with stock stops. not crude, just home brew. nice work.

I should be able to just move the stop over. I'll check it out tomorrow.

mines non hydraulic and does the same thing but i just push it back into the stop with the raker. works for me. looking for a square grinder though.

Yep, I can move the stop side to side enough to get it out of the way.
