As our chainsaw uses increase the need for sharp chains also increase. As a machinist, I have done a lot of tool grinding for many materials. While it is common to file chainsaw teeth, it is nearly impossible to make a truly sharp and consistent tooth geometry. The accuracy of a tool grinder can produce exact angles, uniform tooth lengths and a sharp edge that lasts longer in use.
I bought a new Oregon 520-120 chain grinder. After doing my research on customer reviews and video research it became obvious that a few modifications to this machine would be needed to meet my expectation.
I have included links to the Machine and vise below should you want to duplicate my set up. Oregon also has a replacement vise with Oregon branding.

Great video friend. You hit the nail on the head saying want to be the go to guy in the neighborhood. I use multiple chains for work and all the neighbors use saws on their properties. I do sharpen by hand but when the neighbors have a few and I have mine it becomes a tedious half day of sharpening.

@SpencersMountain 3 месяца назад

Sharpening is a skill that requires knowledge of tooth angles. Hand work is a greater skill. I touch up chains by hand in the field to maintain sharpness. As a machinist, I have learned the importance of consistency. A machine sharpened tool especially many cutting teeth will always perform better than hand work. The machine sharpener simply restores consistency that is difficult by hand and as you pointed out saves some valuable time. It always requires volume to justify the cost of a machine. If you like the work… people will beat a path to you. Thank you for the comment and thank you for watching!

I haven’t realized that I could get a better vise for my 511A. I had pretty much given up on the machine because of the vise movement. Thank you for the link to order a better one.

@SpencersMountain 9 месяцев назад

I think the 511AX had the vise like I converted to. It appears Tecomec makes Oregon grinders and shrewdly manipulates options making higher end versions hold the good parts. You will be much happier with the upgrade vise, it is a much better functioning vise. Thank you for watching.

@johnwoody4905 Год назад

good video and job. you went into more detail than most videos on theses. i am sure you will make up grades and make it even better. take care, be safe and well.

@SpencersMountain Год назад

Thank you John. This video was mostly an initial experience. I will have more videos as some plans come together. As always, thank you for your comments and watching!

@markking5711 Год назад

I HAVE THE SAME GRINDER! I JUST ORDERED A VISE LIKE YOURS! GOOD VIDEO!

@SpencersMountain Год назад

Seems to be a good grinder. The upgrade vise is a worthwhile purchase. I reviewed many videos before buying the grinder and noticed many issues with the stock vise with chainsaw teeth jumping out of place during a grind. You will be happy with your decision. Thank you for watching.!

Nice sharpener, maybe a tooth advancer would be a nice mod.

Well...I am not a stranger to self-advancing sharpeners. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-eqXApsDdAmw.html Thanks for watching!

@LM-ru6df 3 месяца назад

Nice video & explanations. I have to wonder though, buying this unit PLUS a new vice, the cost is slightly lower that the higher-level Oregon grinder; why wouldn't you just buy the next model up? Also, if you did look at buying a Tecomec, what made you go with the Oregon instead? I'm really interested in hearing your take on this.

@SpencersMountain 3 месяца назад

Main purchase decision was price. I found a very low price about half normal good street cost. Similar deal on the upgrade vise. Tecomec makes Oregon grinders. The product lines are carefully designed to maximize price point and product name. My decision was for a good grinder motor, upgradeable vice and vice offset capacity. Basically my goal was to replicate the Oregon 511AX that has been discontinued splitting their product line into a machine with poor vise or much higher cost. Careful product research and shopping for a clearance price got me what I wanted. Left over savings will pay for a CBN grinding wheel with improved grind quality and eliminate wheel diameter changes from wear of standard wheels and maintain the grind centerline adjustment. Hope that answered your questions. Thank you for watching!

Nice video; I love watching craftsman do reviews! About what size bolts did you use to mount the base? Looks like 5/16ths?

@SpencersMountain 8 месяцев назад

Before laying out the cash for a machine like this, I do a little research. RU-vid has some pretty good video information and I learn a lot from those videos. Only seems right to pay forward what I learn so others may benefit from my experience. My experience as an amateur and professional machinist has put me in front of many machines used to sharpen tools. I can use that experience to review machines. Yes, the base bolts are 5/16”. 1/4” would also work well. Thanks for the kind comment and thank you for watching!

@farmhandluke5182 8 месяцев назад

Thanks for the in depth video! Did you purchase the cbn wheels for this machine yet? If so could you show the numbers or a link for 3/16 sharpener wheel and a 1/4 raker wheel ? Thanks,

@SpencersMountain 8 месяцев назад

Thanks. Have not bought the CBN wheels yet. This site has been recommended in a few places I have researched and had good reviews. www.diamondwheelinc.com/chain-saw-wheels.html

@markking5711 Год назад

I HAD THE SAME ISSUES THAT YOU HAD! I HAVE MINE ON THE TRIPOD! TIGHTENING VISE IT WASN'T AS STABLE AS A BENCH! NEXT PURCHASE WILL BE A CBN WHEEL! THANKS;

@SpencersMountain Год назад

Let me know what you get on that CBN wheel. I have done machine work with CBN and it is miles above typical bonded grain abrasives. Shape and diameter stays nearly the same maintaining grinder geometry.

@bobweiram6321 Год назад

It would make a nice bandsaw blade sharpener with some modifications, but not as good as the one you built.

@SpencersMountain Год назад

Thanks Bob. Would have been fun to make another grinder, but not enough time for this one...still could not help making a couple of changes. Thanks for watching.

@bobweiram6321 Год назад

@@SpencersMountain I have my eye on one of those chainsaw sharpeners for use as a handsaw toother/sharpener. I've considered a punch-die and a press, but the cost is prohibitively high. A 60 degree triangular punch and die costs more than the chainsaw sharpener.

@SpencersMountain Год назад

@@bobweiram6321 I feel the chainsaw grinder might be under-powered for metal removal to create a tooth. I have seen a couple of Belsaw chain filers on sale lately that might work for you, but are bulky machines. Files are relatively cheep compared to dies. In low production, I have seen converted radial arm saws used to make blades. Used ones are cheap, lots of angle adjustment, reasonable horse-power. Durable grinding wheels will be the expense on that idea. A simple blade holder and adjustable tooth stop and you could be in business. Thanks for watching!

@user-oj5gc2vs1e 8 месяцев назад

Great video, need to change my vise also, where did you get yours?

@SpencersMountain 8 месяцев назад

I put Amazon links in the video description for Tecomec and Oregon vises. Use the links or search part numbers listed there to find another source. Hint: Tecomec makes these grinders and parts. The vise handle provides a different color and has Oregon on it, no performance difference and higher cost usually. I think I found a good price on eBay. Appears to be a lot of disappointment over the stock vise. Thanks for watching!
