Oregon 620-120 chainsaw chain grinder

I have a cheaper one from Princes Auto.. (Canada's Harbor Freight).. it works well when obviously set proper but the chain break doesn't hold chain still and tends to jump up a bit and when a little too aggressive on the break will move off 30 degree.. the hydraulic assist and the better quality built will be a game changer to how I sharpen now.. great informative video..

[@clockguy2]

I have read on logging forums of folks throwing out the angle charts and going back to 60, 30, 0 degrees for all large chain and 25 degrees for smaller saw chain. they say that their saws cut just as well with these angles and it avoids confusion. That is, 60 degrees on the rear knob adjustment, 30 degrees on the bottom knob adjustment, and keeping the 10 degree down angle set at zero.

[@GoodDayFarm]

Those angles would work well. That’s what is great about the grinder, you can play with the angles and know for sure what angle your doing, and do what you like best. I like an aggressive angle, even if it dulls easier, I just swap chains and keep going. I can grind or file them later when I get home .👍 Thanks for the comment, thanks for watching.

Saw Surgeon hello man, eye the grinder lol....as GDF likes his unit I like my 520....once you have the grinder you will wish you would have bought it a long time ago.....you can grind a chain that easily cuts as good and long as a factory new chain, and that should be your goal!!!

[@sawsurgeon]

Kyle Studebaker) My employer has an el-cheapo one much like my dad's. I use it for work chains and on the rare occasion when I get into something nasty with my own chains. Otherwise I hand file my personal stuff. I cut primarily in woodlots so there is little contamination and am pretty cautious when cutting near obstructions. I'm no Buckin' Billy Ray, but I can put together a pretty sweet cutting chain by hand. As for work, our crews do a lot of flush cutting of stumps... Our crews go through an amazing volume of chain for no more cuts than they make! I can see there is absolutely no comparison between the Oregon and the plastic bodied units. I'll have to look a little closer into these models. To this point I have managed to stay out of fence rows. I have friends that have had to deal with that stuff. Way too much debris for my liking! Be Blessed!

Sorry for the stupid question but I’m new to grinding and just bought this grinder and getting it set up. How to you know which setting to set on the chain clamp?

[@GoodDayFarm]

Never a stupid question.. 😊 Depending what brand of chains you run, the manufacturer will have suggested angles for that specific chain. But a general rule is 25-30 degrees. Unless you’re killing, then it’s 10 degrees. Hope that helps.

[@sonko2010]

What’s your opinion on the holding power of the hydraulic clamp? Better hold than a manual clamp? Thanks.

[@GoodDayFarm]

I’ve never used a manual one, but the hydraulic is great! I’ve never had an issue with it. Holds very tight as long as you select the correct chain gauge.

[@landonsvlogsvlog6007]

is the hydraulic assist worth the extra money??

[@GoodDayFarm]

I’ve never used a standard vise grinder, but it is pretty nice not have to lock and unlock the vise for every tooth. Definitely speeds things up.

[@billdegroot4069]

No one has emphasized that each tooth should be ground the same length for optimal cutting performance. In order to achieve this, one has to locate the shortest tooth first, make a stop setting , then grind all teeth to this length. If this is not practical, that is if you would be grinding away most of your chain teeth, then you may not want to do this. Set this chain aside for rough work, but save your best chains for falling where optimum performance is required.

[@GoodDayFarm]

As long as you set the depth gauges, rakers, it’s not critical that every tooth be the same length. 👍😎

[@highwatercircutrider]

Tooth length makes not difference. Raker depth, uneven sharpness, loose bar grooves, bar rails at different heights, worn out chain drivers....these things do make a saw cut to one side or poorly.......I am a Michigan logger and circle sawmill owner for 30 years

[@GoodDayFarm]

Exactly!

[@highwatercircutrider]

Good Day Farm check out ‘Buckin Billy Ray’ on KZbin. He did an extensive video test on this very subject and came to a similar conclusion. I had always suspected tooth length, but never studied it carefully, now it has been proven by several...ps.. I still check tooth length out of superstition and my sharpening customers like the looks of it much better !...hehe Gary in Michigan

[@michaelvelasco7942]

Either... you have great reviews on all the different options. I was leaning toward the 620. Just wanted your opinion on, if you could have one for the bench and one for the field, which ones you would prefer.

[@GoodDayFarm]

If you do a lot of chains, the 620 is great for the bench. Otherwise a chain vise and a Stihl 2-n-1 or Granberg would be fine... if you’re not just doing free hand. For in the field... I always take extra chains and just swap out as needed.... but I will have a proper round file and flat file with depth gauge in case I need it. That’s another great use for the 2-n-1.... as long as you set your tooth angles standard. If you’re doing some custom angle, then free hand or Granberg.

my local stihl shop sharpens customers chains at 30 degrees and sets the angle grinder wheel at 40 degrees. 40 degrees too steep?

That depends on the grinder the Stihl grinders are different. I think 40 degrees on a Stihl grinder is the same as 50 degrees on the Oregon grinder. That would give you a strong edge on the cutter, not as sharp, but durable. That would be acceptable Personally, I prefer a sharper edge, even if it isn’t as strong. Thanks for the question, and thanks for watching! Take care and have a Good Day.

[@user-cd7jx2td8n]

My concern about bench grinders like yours is how consistent they are. In other words, how well does the vice mechanism on your grinder hold the chain? If it's not holding the chain perfectly still for each and every tooth, you will obviously end up with inconsistent grinds, right? Another question is how well the grinder is set up for changing direction for grinding the opposite teeth? I'm sure that you've used a chain that wasn't ground the same on both sides, which causes the saw to essentially "walk off" and, more to the point, not cut straight. I have both liked and subscribed to your channel, so please keep on making the informative videos. 👍

[@GoodDayFarm]

In the time I had and used this grinder, I didn’t see any issues…. Although I can understand your concerns. I think it comes down to the quality of the machine. This one is built very well…. But I’m sure you’d have those issue with lesser quality machines. Unfortunately, I don’t have it anymore, I don’t cut firewood anymore, so I can’t give you a long term review. Thanks for the comment, thanks for watching. 😊👍

[@user-cd7jx2td8n]

@@GoodDayFarm Would you like to sell the grinder? In my experience, manufacturers tend to increase their margins over time by "modifying" their designs. For example, they may decided to sub what were once quality steel parts for cheaper/inferior pot metal parts that aren't as durable. In short, I trust an older unit over a newer one, so let me know if your grinder is presently collecting dust in your shop. Have a good one.

what happens when u heat the chain up too hot?

[@GoodDayFarm]

Good question. If it gets hot enough to discolor the steel, not just burning off pitch or oil, but if you blue the tooth.. it changes the temper in the steel. It won’t hold an edge as good or at all.

I didnt really hear him go over the setting thats got to do with the chain angle, its where you slide it it back and forth.. I was wondering if someone could explain?

[@Smokey66s]

I am confused about the direction of wheel spinning in relation into teeth on opposite sides? My question probably is also confusing, hope it is translatable?

On this grinder, unfortunately the wheel direction is not reversible, so one side it grinds into the teeth, but the other side it grinds away. I’ve never seen an issue with this though.

[@redgum1340]

G'day, what do u do with the teeth on the side where the grinder 'exists' the sharp side of the tooth. That is, the grinding wheel 'enters' one side where it leaves no burrs. However burrs will develop on the teeth of the other side. Obviously, that side is not as sharp and will not cut as well. Then you have a chain that will not cut straight.

[@GoodDayFarm]

Well... in my experience, both sides are equally sharp, the burr... if any... is not an issue. Also, this would not effect if it cuts straight, that would be more of a raker or user issue.

No, mine stays cool. I am on 110. Not sure how or if a transformer would effect the motor.

Brazil is on 50hz US IS 60 hz

You got a video of doing the rakers?

[@GoodDayFarm]

Nah…. I just do them by hand on the bar, pretty easy.

motor needs to TURN BOTH DIRECTIONS as burr will form on one side of ALL TEETH.

[@GoodDayFarm]

+Air Port Unfortunately, the Oregon grinders do not have that option. I haven’t really seen an issue with burrs. I take light passes, do that helps.

[@aktrapper6126]

The burr will come off first cut with the blade.

Все отлично, только, ничего не понятно.

After 10 chains my wheels end up messing blade up . They seem to lose round ness

[@GoodDayFarm]

Are you redressing the wheel? I check the wheel every chain, and usually redress every 2nd or 3rd chain. Of course now I have a CBN wheel, so I don't need to reshape the wheel anymore. Yay!

TWO COMMENTS,, ,Do the rakers with a 3/8 wheel at 10*,,, and don't run the grinder in the cold, this ran out the oil in the motor bearings , and caused a burr at the chizel on the exact machine you have. FYI

[@GoodDayFarm]

Good info, thanks! 👍

[@JanYi2023]

Great video, great explanation, but the grinder itself is vert poor quality it is NOT even close to professional grinder, also the grinding wheel has no reverse, angle adjustments are very crude and approximate. I am sure it beats the file, but it ends there. Thanks again for the video.

[@GoodDayFarm]

Thanks for watching!

[@GWAYGWAY1]

Silly place to put it, the plug is directly behind it , right where the METAL GRINDINGS go just to give you an electric shock.

[@GoodDayFarm]

Are you being serious? There are no issues with the plug ... 👍

[@GoodDayFarm]

Btw... there is a sheiks around the grinding wheel, very little, if anything gets behind the grinder. 👍
