A Chairmaking Revolution

The Chairmaker’s Sighting Square.jpg

You may have noticed that Chris and I have been making a lot of chairs recently. In the past few months, we’ve made a few incremental improvements and changes to our processes that make charmaking easier, more accurate and more enjoyable.

But now, we think we’ve come up with a tool that will revolutionize your chairmaking process – and rather than just write it up, the millennial-in-residence (that’s me) decided to make a flashy video to share our innovation with you.

So, please enjoy the video below about our latest innovation, the “Chairmaker’s Sighting Square” – and scroll past the video for the necessary files to make your own.

    Still laughing

    Is it April first already?

    Vimeo perfection

  4. Rachael Boyd says:

    I’m sorry I know I shouldn’t be laughing. I now need to make one of them there squares to see if they work as good as you say. giggle

  5. occasionalww says:

    Can I get it in a left handed version?

  6. Brian Ogilvie says:

    That was truly artisanal!

  7. Mark Bickford says:

    Simply outstanding! Naturally I assume I will need to raise my own piglet into a hog so as to harvest organic, sustainable hog bristle. Which begs the question of which part of the hog yields the bristle? Also, is there a best practice methodology for harvesting hog bristle? After downloading all your free plans, drawings and templates I would like to attend a class in your shop on building this device. However, I would much prefer it be one on one so as not to be distracted by others during my learning experience. Looking forward to your immediate response though my tongue seems to be firmly lodged in my cheek.

    For version 2.0, if you attach a plumb bob you will make your boring friend’s job a lot easier and more accurate. Also curious as to why boars hair and not the hair from you boring friend? He seems to have removed a lot recently. Looks good by the way. Makes the beard look spiffy.

  9. J.C. aka BLZeebub says:

    Somebody has way too much time on their hands. What the heck were you drinking at the time you hatched this one? And where can I get some?

  10. Jonathan Schneider says:

    Highly enjoyable!

  11. Harry says:

    Is there one for left-handed people?

  12. Absolutely wonderful!

  13. John says:

    That was almost as believable as the horrific exploding workbench!

  14. Chris Bame says:

    Freakin Brilliant!!! I now must make a chair just to build and use this contraption.

  15. Kyle Barton says:

    Fantastic! While the square will absolutely advance the chair making craft; the “boring buddy” is simply genius 😉

  16. Bob Glenn says:

    Can I have my four minutes back?

  17. Dave says:

    Just completed mine – I could not find a cheap source of boar’s hair so I substituted chicken feathers…. and I don’t have a friend.

  18. REM says:

    Also VERY useful for sighting dovetail angles. Finally, a new and different way to cut dovetails. I built one this morning and made a video explaining how to use it for dovetails… https://www.youtube.com/watch?v=dQw4w9WgXcQ

  19. John Hoffoss says:

    Nice antiquated version of this tool…I just got off the phone with Lee Valley, and they will be working with Woody Woodpecker to introduce The Improved Chairmaker’s Sighting Square (TICSS), assembled by the newest in C&C machining and laser-guided robotic assembly using a combination of O2 tool steel, 6061 aircraft-grade aluminiuim, and will be adorned with the latest technological carbon fiber fibers to re-revolutionize this revolutionary tool, unearthed from an ancient Atlantisian text on woodworking, who also invented sitting.

  20. jayedcoins says:

    Well done, fellas.

  21. warren says:

    I think Home Depot has these on-line

  22. I laughed so hard… was not expecting this so far from April 1st. Brilliant.

  23. Brian says:

    Useless! Unless of course you can also invent a buddy for me.

  24. Matthew Holbrook says:

    Enjoyed this video. Brendan looks good in the rose shirt. It goes nicely with the other good looking woodworker in the black shirt. I think his name is Christopher Schwarz.

  25. sjldwoodworking says:

    Brendan – funny video, thanks. Re: the Fir you used. I have a ton of similar stuff laying around, and didn’t realize it would be good for tool making. Haven’t imagined using it for a plane or tool handle, which doesn’t sound quite right to me (but I’m probably wrong). Beyond squares what tools would be good to make with it?

    • sjldwoodworking says:

      Or, perhaps I’m the wiener in the comments, and that was a joke too. Who the heck knows! 🙂

    • brendangaffney says:

      Straightedges, chair sticks, rulers, squares… good for stability in measurement. You’re correct in thinking it may not be so hot for totes and handles, I believe.

  26. Jared says:

    It seems this video marks the divergence in which this institution has evolved from its individualist-anarchist roots into its more communitarian present state.

    Build by yourself? No, build with a buddy. Or comrade, if you will.

  27. Bill says:

    I won’t bother making one as they are selling an electronic version in Harbor Frieght for only $5.99 plus tax. It is more useful than the wooden one as you don’t need a buddy to assist.
