Let me begin by saying that I am just a typical homeowner that heats my house with wood and I cut multiple cords a year. I enjoy firewood cutting and running chainsaws and through the years have used about every sharpening tool available. I finally decided I needed to step up to the Oregon grinder after a long bout with files, rotary tools and hand cutters(Timberline). When the Oregon Bench Grinder arrived, I mounted it on my bench and proceeded to adjust it according to the instructions. What I found was that the grinding wheels are wider than their advertised size. This resulted in reforming the cutting profile on the cutter tooth and removing a lot of metal in the process. The other problem was the chain guide. This particular model has a cheap guide made of two parallel rails that pinch together in the middle. The distance between the rails is so wide that the the chain flops around. When the handle is rotated to pinch the chain in place, it only pinches in the middle at a small point. The issue was that the chain would cant when the rails were pinched. This made it impossible to get even results on both rows of cutters. I ended up taking the mounting bolts out and filing down the blades that separate the two rails so they were much narrower and held the chain better. This solved the canting problem and now holds the chain in a solid vertical position while sharpening. The other problem with this kind of grinder is that the wheel only spins in one direction. For the left side cutters, the grinding wheel leaves a large burr which affects the cutting action of the saw. I have watched youtube videos of others who have this problem. One solution was to spin the grinding wheel in reverse with a drill and then switch the motor on which then ran the wheel in the reversed direction for the left side cutters. ( I haven't dared try this yet). My last fix was to use a grinding wheel one size smaller than normal which gave me the ability to more accurately adjust to the contour of the cutting tooth. The grinder has a couple of adjustment "bump stops" to restrain how far the grinding wheel cuts into the cutter tooth, however, there is a lot of flex in the adjustments and great care must be taken to keep all the teeth sharpened equally. Conclusion: Yes, this grinder works. It is much quicker than other methods. However it isn't perfect and requires some careful adjustments and attention to detail in order to make it sharpen a chain with satisfactory results. Yes, it can sharpen a chain, but don't expect to have new chain like sharpness without a lot of time invested in adjustments and technique.

Received it today. Easy assembly had put together and sharpening chains in less than an hour. Easy to use does a great job.

I had been using a sharpener from Harbor Freight for 25 years and always wondered why my chains were never sharp like new. Now I know exactly what was wrong, that old one was junk.The first time I used it, it was absolutely amazing and setting up for cutting takes just a minute and then I was off to the races.It goes through a 20” maple that’s been laying on the pile for two years like a hot knife through butter saving me time and money.Thanks for the great product, I’m lovin it !RICK

No more waiting to get chains sharpened. Should have bought one years ago. I bolted down to a bench. Works well and has quiet operation. Key is to know what type of chain and cut angles you have. Its a bit of a learning curve to get everything set up.. Thanks for including a dressing stick. You will need to dress the side of the wheel with this stick occasionally to keep wheel sharp and dressed.

Quality product.I recommend this grinder, it is good value.
