GENIUS. Reversing the motor with the drill works because you're spinning it up past the speed where the starter winding switch disengages, and then the wiring is exactly the same!! AWESOME. You could probably modify the motor with a direction switch, but your drill hack is GENIUS.

I was positive this was the reason my cheapo did not work. No sparks from the tip. I knew only half the chain was getting sharpened. It seemed wrong or counterintuitive from day 1.This major flaw should be all over the place but all these other guys do is 3 minute videos for click bait. So THANK YOU. PS: I refiled the one side by hand on the first chain. On another chain, I cut into it a bit and that semi worked. I' guess that's why they cut off half your blade when you have it 'professionally done'. It all makes sense now.
@jeffreymoncur86345 жыл бұрын
I attended a class put on by Oregon years ago and they recommended then to do as you did and go to the 55 degree angle. They claimed that after testing you get on the average more cuts before dulling. My customers loved it! The resetting of the teeth length is due to the bed of the vise/table axis. The spendier models now have it so you can adjust this and a scale down by where the bed pivots when you go from left to right 30 degrees. It allows the bed to move forward or backward to square the pivot point up with the blade at 0 degrees. You can see the scale on the side/bottom of the newer model 520-120 and up Oregon grinders. It is supposed to adjust for "minor" factory machining differences. Gonna try the reversal trick though, great idea!

I battled my Oregon sharpener for years. I'd get it adjusted and then it would do ok for a few chains and then right back to the same old cutting in circles. I always thought it was the centering of the wheel over the vice. I ran it backwards for the left side as this video showed and the chains cut just like new. I tested my saw on fresh oak out in the rain today. I couldn't believe the difference. It cut in half the time of yesterday. This is the greatest video ever made.

You could rotate the motor either direction depending on which side of the chain you were sharpening. The new models come with the one-way switch like yours. My new one sharpens like crap compared to my old one and I was convinced it was because of this reason as well. Was looking at a way to rewire the motor to make it bi- directional but your solution is great! I never would have thought to have tried that. Thanks!

-Good video which shows the importance of using the caliper to assure equal tooth length and importance of removing burrs. My shop has been closed for a dozen years, but I used the middle priced Oregon sharpeners (about $280 at the time) with two set up sharpening (one for loggers chains, one for homeowners small chains) and a third one one set up for the raker teeth. Loggers would bring in chains that were just thrown in the back of a pickup, exposed to rain and with stiff links. I would have to soak those chains to loosen them and wire brush them to remove resin. I advised those loggers to keep a bucket of diesel fuel to throw the dulled chains into. That helped quite a bit. My old loggers have died of heart attacks, but were savvy about tree felling so that did not do them in. Home owners often started their chain saws on the ground where momentary contact with the ground would immediately dull their chains, then complain to me that I didn't sharpen the chains well. My sharpening process always took quite a bit longer to do than local hardware store sharpeners took, but I didn't charge more. Don't miss the business and now only have my personal sharpening to do.

McCullough 10-10 and sharpened either the left or right side cutters (don't remember the side chosen) right down to no tooth left and then went and took a good straight 1/2" cut (cookie) off of a 20 to 30 ish inch diameter log. IIRC he said what matters is proper depth gauge height in relation to its respective cutting tooth! (And no I am not looking to start any BS,because I was amazed by this also)

Thank you very much for the video! Your meticulousness is impressive, I like it! Stephen Leacock has written there was a reverse switch on the 20 years old sharpener. Everything is cheap and made in China nowadays :( . There is more right way to make the reverse in an induction motor: you have to disconnect the main winding from the starting winding and install a "bipolar" switch into the chain of either winding. When you reverse the polarity of one winding relative to another, the motor will start spinning the opposite direction. I have done this to my cheap Chinese drill press (it was a lot of work though). But your way of changing the direction is 100% workable and awesome in its simplicity!

I need to put a new video out giving an update. A couple of months ago I figured out what the real problem is with this machine. The real problem is that is never centered properly from one side to the other. And I could not get it to work no matter what I did. Problem was solved by accident which often happens it seems on things that are really weird. If I turn it to the right and set it at 30 degrees and turn it to the left and set it at 25 degrees everything is absolutely 100% perfect. So they had screwed up the angle from the factory now I don't get any burrs I don't have to do any measuring everything is absolutely perfect it's just amazing the difference. One more thing that I did since then is I tilt the back angle to 55 degrees that also helped with the burrs.

Jerry, who would think the motor would run in the opposite direction.? Good on you for figuring that out. I just bought a brand new chain in September for my wood logs. Yeah, nothing cuts like it a new chain. My local saw shop sells an Oregon contraption that is supposed to be THE ultimate saw file. Set at 35 degrees, I think and lines to see if you are at the proper angle. One feature is it takes down the depth gauges, so called "rakers" at the same time. They come in various sizes depending on the chain pitch. Dale was out of stock at the time I got the chain, now, I don't need it yet til next time I cut logs, which may be in another month. With this Montana deep freeze we just had, I burned enough to power the Mississippi Queen up river in a race. It's above zero for first time in about 55 days. Supposed to be near 40 above next Monday. Hurray !! Cheers, buddy. Bob

I've been meaning to put out an update. I have discovered a few things since that video. First I now set my back angle to 55 degrees. That helped a lot with the Burr. I have discovered that the machine was designed incorrectly or a manufacturing defect whatever you want to refer to it as. In other words the scale on the front is absolutely Wrong by 5 degrees each way which makes it a 10 degree error. I took time to measure everything precisely and figured that out. Basically the scale on the front was just mounted to the left by 5 degrees. So to fix the problem I turn it to 30 degrees on the right. I turn it to 25 degrees on the left and now everything is perfectly centered all the teeth are cut exactly the same length I have no further problems with it. Mine was manufactured in Italy I would imagine if yours was made there you probably have the same problem. And finally the third thing is I bought the CDB Wheels. Yes they're crazy expensive. But in my opinion worth every penny. It's night and day difference in terms of what they cut and how they cut.

I've been sharpening chains a long time, I used Stihls grinder, but I have the 511A identical to yours. If you are getting a burr your taking to much material off. I also don't go by there 30° angle on every chain. Sometimes I eye ball the chain and adjust to the chain. You are right the chain grinder is not as easy as 1,2,3, I don't think we can ever get a chain as sharp as the manufacturer. But as long as your getting the results that make you happy that's what matters, like they say there is more than one way to skin a cat. The grinder takes a good eye, looks like you found your methods. Happy cutting👍
@johnmayse75493 жыл бұрын
I have a electric grinder that I use when chains are in bad shape. I hand file my own, because unless I hit metal or rocks or dirt I file until I can't see an edge on the cutting edge of the tooth. If you can see a shine on the edge it is not sharp.

I was set on buying the oregon 620-120 which is probably same in accuracy. I learned a little from your techniques. I would have taken the burr off the top with a fine flat file. Kind of hard to be accurate without grinding too much off the cutter with the dremel tool. The oregon seems to be the best for the money but I thought it would have been more accurate. I'm not surprised though. Thanks for a good video.

A small medium or fine stone will knock off the burr without marring the top surface at all if they are chromed and only lightly polish unplated cutters. The stone also has zero chance of dinging a cutter like a dremel can if you slip.

Thankyou Sir. I have a similar grinder that I got new a few months back. Started out ok the first few times I used it but began to notice that the saw was cutting to the left and seemed to be getting worse after each sharpening. The last time I sharpened the chain I measured all the cutters and ground accordingly + I flipped the bar over as well for the first time in its relatively new life. It still continued to cut to the left. Frustrated much. I am looking forward to having another crack at it after watching your vid. NOTE: I have noticed that when sharpening one side that the center of the stone wheel is positioned directly above the cutting tooth but is offset when I do the other side and therefore, I think, doesn't sharpen all the way down the side of the tooth into the "gullet?" Not sure if or how much this may be affecting the cut. Anyways, thanks and Peace from the Land of the Long White Cloud.

The vice clamp may need realignment. That's why there is a set screw on the back of clamp. Loosen locknut, place a straight edge in clamp, pull head down to working position ( stopped ) & adjust screw till straight edge is in central line with spindle bolt of wheel. Tighten locknut. Do test grinds on scrap chain to verify. Good luck, stay safe.
@colharkin78865 ай бұрын
There is one other point regarding settings on these Oregon sharpeners. The grinding wheel will change profile over time and needs to be adjusted back to a flat surface. The grinding wheel will become rounded on the outer edge. A small very hard grinding block came with my sharpener which is to be held flat against the side of the disk being used for sharpening, while the sharpener is switched on. You will be able to see when the disk surface has been restored. That fixes this problem easily. Obviously, you can take the grinding wheel off and reverse it but the problem won't go away because that side will eventually change profile as well. I wish to add that a demonstration video came with my sharpener and the instructor wasn't grinding each tooth for too long. Two or three short hits and no more. He did this to avoid over-heating the tooth and therefore softening the steel.
@shawnconley16953 жыл бұрын
That burr on the top, if you take your chain and touch it on a wire wheel on your bench grinder, it comes right off. You can even dress the the slight burr on the side plate plate as well. I've had a saw sharpening business for 20 years and it works famously. Be sure to keep your wheel dressed properly as this will reduce the size of the burr. Great video by the way.

I’m very pleased to find this video. I’ve had all the less than optimal results sharpening chains...very discouraging but I’m not giving up my search for knowledge! I don’t know why DIY can’t learn this skill to rival that of a professional. It just takes someone like this man to share their approach. We’re not talking brain surgery here but like a brain surgeon you need the right technique and tools. I ordered a 10x magnifying glass so I can.do a careful inspection of the tooth. I need to see these dang burs. I ordered a caliper to get .01mm tooth digital measurement accuracy. I clean the chain before starting in on the sharpening...I’m prepping for surgery! I will definitely use a respirator to keep those fine particles out of my system.

I enjoyed your video and having just bought an Oregon sharpener, I didn't know about the bias grinding differential for tooth length. If I have understood what others have said about the stop/tooth relationship being the only relevant thing, then I would have to disagree. If a stop/raker is higher, then it seems logical that it would 'lift' the next tooth creating less bite and a dominance to one side. My machine has a cover over the wheel and I imagine yours did too. If one were to drill a hole in the safety cover, it would allow access to the hex screw w/o compromising safety. Removing burrs? I think that is overkill. It's a moving chain, not a knife and very temporary, but I defer to you. I like to run a chisel tooth chain on my larger saw, but today I looked at a new Stihl chain under a magnifying glass and was surprised to see how off the intersection of the grind was with the point and the wall; not even close. Now that matters! Thanks for the video!

As mentioned by others my older has a 2 way switch and can rotate the motor either way. Regarding not cutting the teeth the same length, there are 2 adjustment screws when you remove the chain vice from the machine. On my model this problem is fixed by cutting a slot with a hacksaw into a piece of metal that can be locked into thr chain vice. Place cut under grinding wheel with tilt set at 90 degrees first. Rotate chain vise to 30 degrees right. Make sure its still over cut. Do the same rotating to the left.. If it isnt in correct spot you will see this. Remove vice from machine and on the underneath loosen the 2 screws and slide fractionally one way or the other. Also my vise tilts and right hand teeth( closest ones to you) need to have vice pushed away from you and when cutting left hand teeth bring it back to you. Hope this helps fix your issues as the oregon sharpener is a great tool and produces extremely sharp chains when done correctly.
