Looking for someone to sharpen chains and convert to milling/ripping.

[pbillyi69]

I'm familiar with cutter angles when grinding chain (although I don't have a grinder myself) are you referring to the inside top plate or side plate too? I hand file so I usually don't pay much attention or try to figure it out. I believe a 7/32" file produces somewhere around a 60° top angle on 3/8 chain, or are you referring to what I would call "down angle" when hand filing (I have no idea if that's the proper terminology) when I hold the file handle at a downward angle 0°-10° when filing?

if you look at one of your cutters from the front or the cutting edge are they thin like a knife or more like a chisel those are the angles i am referring to when i say inside angles

I'll hopefully get some of these new to me chains dulled up before long and then see about grinder sharpening and changing the angles for the 42" for milling.

I do chain sharpening here in albany oregon. I have a round chain grinder with abn wheel and I grind a fair amount of chains through the week as a side gig. If your interested in having your chains sharpened let me know.

Be careful looking for any old dude to change the angles on a long chain.

It's not complicated, but if you get someone who doesn't have CBN and/or patience, your cutters will be harder than your files.

(CBN isn't mandatory if you know what you're doing and take multiple passes, but it sure helps keep the heat down. )

Round grinder is pretty cheap...
Also very easy to change to whatever angle you want. No brainer if you ask me.

Let's say you're paying $80 a loop for Oregon chains... a brand new Oregon 410 costs a little more than 2 chains on Amazon, and you can get a new Tecomec 520 on eBay for about the same price. Add $100 for a cbn wheel, and you are all set to do your own forever for the price of 4 chains.

Being able to grind my own chains has been awesome for me. I get great results without the claimed downsides of grinders. (They weren't at first though, definitely start with an old stumping chain from your smallest saw. )

Right, I follow ya. If you are asking what the actual angles are? I don't know. When hand filling the inside angle on the top plate is set already by the diameter of the file. Closest I can come up with is only what I've read, I think it's around 60° As for the inside angle on the side plate, I have no idea. I'd say the more blunt the better with milling, but I've never tried it any other way. We bought a simington, so when I get it dialed in for milling, and figure out the best compromise, I'll pass along the actual angles. Of course species will play a large role in that decision. If you're just asking sharper or more blunt, I'd say they're in the more blunt "chisel like" category. Now, as for square filed/ground milling chain, I have no idea yet.

i was asking in general if they were more knife like they will cut really good but wont stay sharp or be as durable. the more chisel like they are the longer they stay sharp and the more durable they are. i dont know the exact angles on my wheel but i know it cuts really good in hard wood and cuts through soft wood like butter. if you want me to take some pics of my set up i woukd be happy to

They're definitely more chisel like. If you're willing to share, I'm ALWAYS up for exchanging info and I'm more than willing to learn! I'd really appreciate it! For not having it long, I feel I've got the simington down decent for regular crosscut angles. (There is ALWAYS room for improvement) I haven't tried to go with a super "sharp&fast" grind yet. My angles are as blunt/chisel like as I can adjust for mechanically. It still kicks the crap outta round ground chain. I haven't changed the stone for the top plate angle yet, I've been dressing it at the same angle it was from the factory, but I did change the side plate angle. Seems to be rather durable, and still cuts well. This is kind of derailing the topic of the thread for a moment, but I'm curious to see how "flat" I'll have to dress the top of the stone to keep a low top plate angle for milling. Anyway, any info you're willing to share would mean a lot & be much appreciated.

I know @chiselbit has played with angles on a square grinder. Matter of fact I think I’m gonna go try his chain right now.
