Timber Tuff CS-BMM Benchtop Electric Chain Saw Chain Sharpener

I dislike giving bad reviews and attempt to find something good to say about most everything.That being said:The bad:1. Got it mMonday, set it up Wednesday and almost made it through a 16" chain before it burned out!!! -----Just went into the shop and tested it an d it fired up, obviously having cut out due to overheating because the motor is too small to carry the load. This is easily as frustrating as a burned out motor because not even having finished the chain, I have to wait an hour+ to recommence the process. NO THANKS.2. Bought it because the ad said you could see your chain while sharpening. Wrong! To see the chain in the (second) position, you have to hunch over it and twist to get a good view. I had to mount it sideways on my bench to get a straight on view of the grinding wheel and chain. Once it was set up this way it was far more pleasant and efficient to use.3. The chain stop is useless. You will grind it away if you are using it for smaller chains.4. Sharpening a smaller (.043 chain) is a pain because the chain keeps binding in the feed slot as the feed slot is fixed and set for wider chains5. The carrier for the angle locking mechanism would have really benefited from one of the designers ACTUALLY ATTEMPTING TO SHARPEN A CHAIN WITH THIS UNIT! I had to design and build a bushing to keep the pivot aligned and keep it from twisting while sharpening. 30 SECONDS MORE ON DESIGN AND MAYBE 25 CENTS MORE IN MATERIAL COSTS ON THEIR PART and this unit would have been much less frustrating to set up and eventually use. This is why I like products built by the people that actually use them daily. This unit couldn't have been built cheeper if they had used old duct tape and recycled electric toothbrush parts.And the good.1. It is a nice bright color so I can easily find it where I attached it to my workbench.2. Once I worked the bugs out ( 2 hours later - and before the motor cut out) it actually cut a decent angle on 3/4 of my chain.

Prompt shipping and well packaged. These units are a good but the small metal chain guides can drop out..the angle guide is a bit sloppy.. Compared to a retail store.these are a good deal.thanks for the great online shopping experience.

Maybe it's just me, but I tried this thing several times and finally just went back to the rat tail file...I think it take about the same amount of time and I end up with a nice edge (and I don't have to pull the chain off to sharpen it, either)

This was an all thumbs project before, but with the saw sharpener - it works great and saves the frustration.I am very happy with this purchase.

Not a professionsal unit but it gets the job done. Very easy to use and adjust for different angle grinds.

Thought I'd try out an economical chainsaw sharpener, Huge mistake, cheap is just cheap.Arrived in damaged box, had definitely been opened, not new as advertised. Was clean but hints of some wear. Poor fit and finish. Instructions were basically a mediocre exploded view, sorta showing where things should go. No written assembly instructions. I figured it out though. Sharpened my chain, just OK, not great. Almost finished sharpening the first blade when it overheated the first time 3 teeth from the end. Came back in 30 min and it restarted. Quit twice more and had to cool off while sharpening the second chain. About three teeth into the third chain it overheated the fourth time. At that point I disassemble and re packed it. Returning it tomorrow.Definitely Not Recommending!!

Sharpened 6 chains great, number 7 motor burnt up wont turn just hums.

Okay, here's the deal: this is a Chinese knock off with poor assembly and use instructions. What else is new? But anyone who feel they have enough mechanical skills operate a chainsaw and also sharpen its chain can figure this tool out. If you think you cannot assemble and operate this tool based on basic logic, then stop right here and buy the expensive Oregon model, because the assembly instructions are indeed a head-scratcher. If you need a better manual or want to get better insight, go to Northerntool (model 193021) and download their model .pdf which the same exact tool. But it's the same tool, same factory, different color so most likely the instructions are the same.I will apologize ahead of time to the few anal purists out there who may disagree with my take on this, but here goes: You first take your oldest or worse chainsaw chain - the one that's just about on its way out - and use it as the first chain to be sharpened. If you only have one then take your time aligning it on the grinder before you start grinding, because you can ruin it. Better yet go out and buy a new chain ($18) to see what the final sharpened product should look like. I used an Oregon model 73 chain which is from my Husqvarna saw; Oregon's web site gives you the specifics for your chain. Note how every other chain link is sharpened in the same direction (RH, LH), in my case 30 degrees.First off be forewarned that if you torque the knobs down on this tool nice and tight, you will surely strip everything out, so just snug things down for now. Also, don't plug it in yet, blah, get everything away that could ignite with a spark, blah, use a mask and eye protection, blah, blah (OHSA nerd, remember?)Once assembled, the rear of the grinder base should be clamped down near the two permanent mounting bolt holes, with the forward half of the base hanging out over the front edge of the bench so the chain can hang freely. Careful, because if you tighten too tight, the cheap cast base will crack.Loosen that side clamping plate knob then reach below; twist the base to the 30-35 degree mark (your chain's grinding angle), snug it down; then hang the chain over the grooved track with the small rectangles holding it in place. At the same time lower the grinder to line up the wheel with the gullet of the chain cutter.Tighten the clamping plate knob against the two rectangles just snug for now, then reach around back and turn that knob to adjust that stop so the wheel so it doesn't allow the cutter to cut further than it should. You'll need to adjust this depth as the wheel gets worn. Still holding that wheel against the chain, flip that finger thingy over and adjust the wheel for it until it sits snug behind the chain link being ground.Once you're happy with the angles, plug it in, and gently lower the wheel towards the chain, give it a hit or two, gently, or risk breaking the cheapo pinko grinding wheel. (The wheel should be dressed with a dressing brick first but get back to me when you buy your $400 sharpener.) Go through the entire chain, sharpening every other (same direction) link.Once you get back to the first link, you will need to turn the motor off and let it cool down a few minutes. Really, do this and been patient. I've read elsewhere that users have had issues with the drive belt, the motor gears melting, etc., so use common sense and let the it chill after every few minutes of use. It's a cheap grinder made with cheap parts. Then leaving the chain in place, swing the base around to the other side, again 30-35 degrees, align it and sharpen through gain. You may have to make fine adjustments here and there; use common sense and you will get the hang of it.Again, not the Festool of chain grinders, but it will sharpen chains for about the price of what a grinding wheel for an upper end grinder costs.

It takes a bit of figuring out exactly how to use it, but youtube videos are great. Once the process is clear, it's quick and easy to put a sharp edge on even old chains. One tip is ALWAYS to clamp the chain before sharpening... you cannot 'cut corners' when using this sharpener.So works as advertised, and cheaper than some manual filing kits!

Works well. Used on over 200 cuts with one sharpening and still cutting well You do have to remove the chain from the saw to use this product but well worth the effort. Much better than trying to sharpen the teeth with a hand file.

I used it for about 10 times and the motor quit working.

Easy to set up, easy to use. Let's me sharpen a chain in less than 15 minutes at the end of the day. A little loose in the adjustments but if you allow for that after a couple of uses you will be satisfied.
