- WW'nTip-of-Day #011 - Chip Breaker
Chip Breakers are evil but necessary on modern metal planes. Here is my tip for solving one of its most common problems.
Note: if you have a Lie-Nielsen or Veritas plane and have a problem with the chip breaker, ignore this video and call them. Those companies customer service are phenomenal and that is one benefit from buying a premium plane. They'll take care of you and fix the issue.

Thank you so much for this video. I don't often leave comments, but this video helped me a ton. I have a vintage stanley no 8 that was constantly clogging. After watching this video and spending a couple minutes running my chip breaker across my diamond stone I am getting great shavings with no clogging for the first time since I bought the plane nearly a year ago.
Great techniques. Thanks. The video of the chipbreaker was very good too!
This Japanese video blows my mind. Thank you for sharing this. Amazing!
Thanks
Wow. The Japanese video on the plane iron was excellent. Thanks very much for sharing your research (and theirs)!
Thanks
Thanks for the link to the Japanese video. It confirmed a lot for me. But what is more important was that some of this can be translated to planers, joiners, and in my case even a 14 inch leather splitter. Even thought these things don't have chip breakers the view of how a cutting edge works through the fibers is priceless and I mean priceless! But... the down side of it all is that every wood has different grain, resin, and moisture content so there is no perfect setting and our only hope is to get a good all around setting. But thanks so much! But an understanding of what is happening is the priceless part of it and to be able to view it while it is happening.
Still, it's mesmerizing to watch.
Its a lovely movie that tells you the range of working parameters. The biggest problem for an occasional wood worker like me is keeping all the instruction to mind when there are all manner of other distractions & I just want to get a good job done. In many cases I find that job either just works as it should or I get vexed at things not performing which is never a good state for a logical appraisal & corrective tactics. As always I have to fight myself & not let the job become the enemy that is deliberately making my life difficult. It is always me that has to figure out what is wrong & adjust. Easy to write, far more difficult to apply. Thanks for sharing!
Hence my now preference for single blades and bevel up.
wortheffort Yes, good point, the less there is to go wrong & be set wrong the higher the chance of things working. I have been conditioned to the Bailey pattern, but one has to always be open to new ideas. Thank you!
Well, nice work inventing that idea. It's already out there - I've seen it discussed in several places. (I'm talking about angling the breaker so that the tip has to be what touches first). I still give you credit - I've had a number of "great ideas" over the years that I was really proud of, and then found they were already out there. We don't get the money for those, but we can still be proud of them. Nicely done!
Fantastic video! This helped me to visualize what's happening between the wood surface, the blade, and the cap iron. Thank you! I'm going to try this on my planes now.
Mesmerizing wasn't it.
Yes mesmerizing. LOL. I watched the video 3 times.
Thanks for the vid and for the link to the research video which was very well done and fascinating. Just shows there is always something to learn.
The professors did some fine videography; Thanks for sharing the link to their research!
mesmerizing ain't it.
My takeaway was 1. Plane with the grain or else 2. take super light cuts or else 3. touch up the breaker and get out your micrometer.
Wortheffort Do you know how hard the wood that they are using (compared to say white or red oak) in the "plane iron" film. Does the species of wood change any or all the films findings? And in a word it is mesmerizing! and incredibly informative.
Yikes - The chip breaker needs to be 0.2mm from the edge to be most effective! I think I'll be setting my plane for very fine cuts to deal with tear-out rather than relying on the chip breaker. And of course choosing my planing direction carefully.
Also, I've found clogging to be most likely to happen when I've tried to set it very close to the edge. I usually set it about 1/16" away - but that's 1.5mm so a lot more than 0.2mm. That and sharpening the edge of the cap iron as you suggest, usually deals with it.
This guy is under-rated.
Thanks
Thank you for the many great referrals. I'm really liking the format this year.
Thanks
When you tighten the screw down you'll flex the breaker a bit, and it will pull at least some of the trailing surface down against your blade top.
Very interesting, but my one concern is the wood being used. Yes with soft wood like magnolia, it doesnt matter, but what about any hard wood. Magnolia is as soft as they come. Chipbreaker for sure for sure helps on hardwoods
I would love to see another set of videos using high def video!
These are HD. You must have your TH-cam settings for lower resolution.
@@wortheffort I meant the video you linked to, created by the Japanese researchers. It's pretty low res, and with today's cameras the videos would be spectacular!
a 0.3 mm offset? YIKES kewl vid thanks
That is an interesting study by the japanese. Certainly gives me something to think about
Wow, both videos are great. Thanks now I know what the chip breaker does.
Thanks
Wow, that japanese video about cap irons is almost therapeutical to watch!
Cool huh?
That was fascinating. I have often wondered just how much the angle on chisels matter. I know guys that swear 22 degrees is the best, some say 25, and they will actually argue their points with out any objective evidence. As long as it is sharp, not 45 degrees and it cuts, it doesn’t matter to me.....21, 22, 25.
The wood or customer doesn't care.
I appreciated your post. Thank you very much!
Thanks
Why does he switch to millimeters suddenly?
Well done that Man, This was a great find I like to know the science rather than mythology of woodworking. It also explains why my low angle Lee works so well without a chip breaker or is that different physics?
Thanks
Very good advise! Thank you.
Thanks
That bonus link was some mind blowing stuff. How on earth did you find that?
So when you say they're not necessary does that mean you'd remove it from a plane like that Bailey or what would you suggest?
With the Baileys style, you have to use them because they control blade movement. I think he meant they're not necessary in theory for the blade to cut.
They're not necessary to make a smooth finish but if a plane came with them they're a necessary evil for it to work properly.
They only exist on newer planes, like the Baily pattern and later wooden planes. Old wooden planes and Japanese style planes don't have them.
The Japanese video you referred us to was EXCELLENT!!!! Very very informative and interesting!
I’m curious though because you said that because of that video it was a reason you prefer single blade (without cap iron) planing. I might be wrong. The video demonstrated that the single blade was bouncing up and down during the cutting without strength support as a cap iron does. Just curious! Thank you very much for the link!!!
Thicker blades don't bounce. End result wasn't much better.
wortheffort Very Good point! Thicker blades would give good results without the need for the fine tuning of angle and distance from blade point for a cap. Do you (or have you) made your own thick blades and been able to harden the steel for prolonged edge life between sharpenings? I only ask because I might like to try a single blade wooden plane.
You can buy them cheap enough from Lee Valley or Ron Hock that it's not worth making your own.
wortheffort Thanks!
Excellent video, thx for posting its link!
Thanks
Excellent - both videos !
Thanks
What tool do you use to loosen the chip breaker screw?
driver built for that purpose
Thanks, enjoying your videos more and more...cheers...rr
Thanks
What grit whetstones do you use for sharpening your irons? Are adhesive backed sandpaper on a flat surface a decent alternative if you can't afford whetstones?
Grits are confusing because there is no standard it seems. I'm guessing these are equivalent of 240, 1000, 4000, and 8000 where my most used are the 1000 & 8000.
Good video.
Thanks
What about bevel down bevel up?
