Battling the Burr
ฝัง

- I have been wanting to make a video on plane blade sharpening for some time now. I know the 20 minute video format we chose just doesn’t leave room for the whole story. The last time I taught a workshop on sharpening was a two-week sharpening basics class at Penland and there still wasn’t enough time to cover everything I wanted to teach.
So for this video, I picked out one aspect where I have seen students struggle without knowing what the struggle was. I am speaking, of course, about the burr or wire edge.
Eliminating the burr that forms with most sharpening techniques can be frustrating. After all, even a microscopic burr can spoil a blade’s performance. So how do you deal with something too small to see?
In this video, I introduce some techniques for creating a burr-free edge that will stay sharp as long as the blade you’re sharpening can possibly hold an edge. And once you understand what’s happening at the edge, you’ll be able to hone in on the problem quickly.
In upcoming videos, I’ll shed light on lots more finer points, but I think you’ll find this one a good motivator to start improving your sharpening process.

your crazy smart......thank you I've enjoyed and learned From all your content,

So I’ve been dragging backwards all along incorrectly thinking it was avoiding digging in on my finest water stone , which is quite soft, when I should have been avoiding that by reducing my pressure.
Fantastic video. At one point it sounded like you would be doing another video. More on this would be wonderful. This was a completely different way of approaching and understanding sharpening. Thank you Brian!

Very well presented. Thank you for sharing your knowledge. I have two of your spokeshaves and I love using them.
This was extremely helpful and informative. Your diagrams of the edge and description of the but being mistaken for a sharp edge blew my mind. Thanks for sharing your wisdom.

I wonder why you didn’t go into establishing a 2nd micro-edge?
Extremely interesting video! I will have to make some changes to my methods the next time I get my stones out! I have been wondering why my edges have not been as sharp (or as long lasting) as I had hoped.. and I think I've found the answers here. Thank you very much for sharing this!

What a great video Brian, I really liked the stropping between the end grain fibers of the stick. And, I thought your first rough drawing of the three edges was very instructive. Thank you very much for show casing my tools. Hap
Awesome presentation and information.

I have found honing in the direction I would be cutting, the stone will eat the burr as it forms leaving me with a true edge free of a burr. It means honing the flat of the iron first and finishing with honing the bevel and micro bevel.
That’s great teaching!
Great advice Brian!

Smaht!!
I like the tenacity you bring to your work and sharing your learning. Sharping tools is so essential to quality work. The 'burr' has been a mystery to me and I followed an informanation al pamphlet that accompanied my first water stones from Norton many years ago and the process did not include taking off the burr by grinding it off but by working through the grits to eventually have it 'disappear' by the final 8000 grit. I still use that process today with great results. Your thots

Most excellent demo on how and why to hone using the plywood example! My preference 90 to the length of blade. Norton has an excellent blade sharping vid also as a starting technique. The students/ user need to learn feed back, observe and l patience. Sharpening is not hard and well as free hand sharping and honing.
Great discussion on this subject.
A good vid would be to talk on grit sizes and um level and standards.
Again another excellent discussion on this subject! This vide should be watch multiple time to pick up on all the points you make on this subject!

Thanks Brian, it seems to me you’re the only person talking about these things. I can certainly appreciate these issues with A2. I choose the steel I use in large part depending on the tool. Obviously the L-N bench planes are A2, but in my Veritas tools, I use O1 on joinery planes and PMV11 on my bevel up stuff. Most all my spokeshaves are old tanged high carbon other than my L-N Boggs Flat and my Veritas Low Angle. I don’t know that I’ve run into crazy issues with the A2 on your spokeshave, it again I think that has a lot to do with its use (for folks who don’t know, the mouth is super tight and you can practically smooth with it). I’m going to try my next project honing/polishing the L-N irons with the final strokes pressing forward as opposed to dragging and see if I sense any differences. It makes sense that the fractures created by a burr in the A2 and A11 would be far more impacting that they had been for so many years on O1.

@@boggsbench thanks, I’m ‘subscribed’, but not for the paid content as of now. My family has a cabin in Maggie Valley that we spend two weeks a year at and the last three years I’ve told my wife that if we head to Asheville for any reason that I wanted to call you to book a few hours of one on one with you while the girls shop/etc…. Maybe this next year (Mar-Apr) will be ‘The Year’! I’m primarily still in my ‘stick chair’ phase, but have also built Buchanan Democratic Chair and built the Galbert No°11 Perch. I’m a retired/disabled Marine Officer of +23 years; a traumatic brain injury ended things for me in 2013. But my 95% handtool workshop has been a literal lifesaver. I appreciate you greatly and I’m grateful for how you’ve contributed to the craft, tools, design, and in inspiring many like me.
Great info! Including some closeups of the stone and blade would also be helpful.

Super video!
Sounds very scientific. Will have a go next time I sharpen my chisels. When you test the burr with a paper towel, do you see the fibres of the paper towel move as they catch on any burr or do you listen for it? Thanks for the video. Cheers, David.
I thought I understand sharpening before I saw this video
