    Huh. I’ve not seen this advice before, but it’s hard to argue with a straight edge.

  2. Gavin Feargrieve on July 21, 2023 at 2:50 pm

    A master class in an essential wood working skill- flat panel glue ups! Great video. As I watched your video I was remembering the evolution of this glue up process in our own shop. Currently, we do it exactly as shown – in every detail. But, we have had employees that swore by using cauls and cranking the clamps to the breaking point. In fact, one fella did successfully prove his strength by breaking a pipe clamp! We had to wonder if there was any glue left in the joint!

  3. Steel Blade Woodworks on July 21, 2023 at 2:51 pm

    Excellent information, loved the straight edge portion!!! Thanks for sharing.

  4. Leigh Hart on July 21, 2023 at 2:52 pm

    Wow, learning something new every time you post – thanks for sharing!

  5. Mathew Campbell on July 21, 2023 at 2:53 pm

    Excellent video Jason. Thanks for this trick. I discovered it by pure dumb luck a couple of glue-ups ago. Guess I’m not Robinson Crusoe…

  6. David Singer on July 21, 2023 at 2:56 pm

    Greatest video ever!

  7. Justin Thames on July 21, 2023 at 2:57 pm

    Love this process glad I saw this right before I’m about to glue up a table.. wood whisperer did a great analysis about parallel clamps and mentioned how they are not the best for glue ups on panels due to bar flexing causing a bow. That was a good visual representation! I’ll use a mix of parallel and pipe clamps and use this technique for sure

  8. Richard Dietzman on July 21, 2023 at 2:58 pm

    Super helpful, Jason. I am in the middle of building 2 desks for each of my sons and the first turned out not so flat. Will incorporate these tips on the next one! Thanks!

  9. Greg W on July 21, 2023 at 2:58 pm

    A great practical and actionable video. Thanks. IIRC you once mentioned you joint boards with a track saw. It would be great if you could show us how you go about that.

  10. Abdullah Ali on July 21, 2023 at 2:59 pm

    Wow!……. I learned so much in this video thank you

  11. Samuel Rivera on July 21, 2023 at 3:01 pm

    Thank you

  12. David Meyer on July 21, 2023 at 3:01 pm

    Thank you Jason!

  13. Sam Wanamaker on July 21, 2023 at 3:01 pm

    One very important thing I would make sure people do with this method, is not just pay attention to the straightedge going flat, but also that you still have the seams together, and not opening the clamp so far that the seams are coming apart.

  14. Skippy Lippy on July 21, 2023 at 3:02 pm

    I learned something new here. Thank you! Excellent presentation.

  15. BVR Railway on July 21, 2023 at 3:04 pm

    Hi Jason, brilliantly video another lesson learnt about glue up!

  16. Jeff Klein on July 21, 2023 at 3:06 pm

    Clear and useful. Thanks!

  17. Andrew Smith on July 21, 2023 at 3:08 pm

    👍👍👍👍 Giving many more Thumbs Up Likes!!! So nice to see basic, but very misunderstood, techniques explained, and visually shown. Thanks Jason!!

  18. Tom Hostetter on July 21, 2023 at 3:09 pm

    That’s great… I have a table glue up coming up soon… will definitely try this

  19. Rostyslav Malashevsky on July 21, 2023 at 3:09 pm

    Thank U! I use same technic when make wide table tops, 20inch+20inch. It really helps, when U need to glue up 2 table tops which arw already finish planned

  20. aaron sailer on July 21, 2023 at 3:10 pm

    Imagine that. Parallel clamps are not parallel.

  21. justcruisin109 on July 21, 2023 at 3:11 pm

    Great tip – thanks for sharing. Cheers

  22. Arthur Soria on July 21, 2023 at 3:14 pm

    This is genius!

  23. steven Bridges on July 21, 2023 at 3:17 pm

    What is the pen your using to mark on your boards? Where did you get it? Thanks

  24. Jeremy Elliott on July 21, 2023 at 3:19 pm

    Another great video. Would this same method work with pipe clamps?

  25. Guy Bowers on July 21, 2023 at 3:19 pm

    This was very useful. I have definitely overtightened my glue ups and this trick week really help to prevent that in the future. I will need to purchase a long straight edge now

  26. Sandy Masquith on July 21, 2023 at 3:20 pm

    Wow!!! Finally! Thank you so much. I am definitely guilty of over-tightening the clamps on my panel glue-ups. Now I understand why I have had so much trouble getting flat panels. Definitely learned something here. Hopefully my next dining room table will be easier to get to flat after glue-up. 🙂

  27. Liam Everything on July 21, 2023 at 3:20 pm

    I have a tip, instead of using a straight edge just use your clamp bars as a straight edge so once your clamp is sitting perfectly flat on your glue up you have a perfect flat glue up! Just make sure your clamps are perfectly straight, anyway good channel and new subscription for me! 😉

  28. Chris Strizver on July 21, 2023 at 3:21 pm

  29. Walter Rider on July 21, 2023 at 3:24 pm

    thank you

  30. Shane on July 21, 2023 at 3:27 pm

    Great video thanks.i just did a similar glue up myself yesterday.same material,size and method. will you use any track or steel on the underside.mine will just be sitting on four legs and have no frame to sit on.i have not made many tops this big without sitting on a frame.i kept the bow to the top which should help.kind regards Shane from Ireland 👍

  31. John Callender on July 21, 2023 at 3:27 pm

    The straight edge idea is awesome. Thanks for sharing!

  32. Marek Ryzyj on July 21, 2023 at 3:30 pm

    pretty cool to see that board settle down. Doesnt that mean that the faces of the boards are not parallel? The gap has to go somewhere?

  33. S Tyner on July 21, 2023 at 3:31 pm

    Sorry to be playing ‘catch up’, as I am kind of new (‘catch-up’ not allowed in the Ranger School (when I was there in ’87… being behind = getting booted out), but **Happy Retirement!**.
    Also, I have to wait to see your downloaded video **after** I have a chance to view it – so this isn’t a stupid question…
    About clamping… I wonder if anyone has done a comparison of clamping force vs. glue joint strength?
    Obviously, somewhere between no clamping force & bone crusher force, is the sweet spot…

  34. JEFF ALLRED on July 21, 2023 at 3:31 pm

    Excellent! Thanks for the tutorial! Makes sense.

  35. Leon Stanley on July 21, 2023 at 3:31 pm

    What kinda marker are you using? Looks like some type of white marker. 8:48

  36. Katherine Carroll on July 21, 2023 at 3:34 pm


  37. RYwoodview on July 21, 2023 at 3:35 pm

    Great lesson. I knew that just joining the edges is enough, but I thought the way to ensure flatness was to use cauls. That may sometimes matter, but to know that you can achieve that just through careful side clamp pressure makes this much simpler. Thanks, Jason!

  38. Stephane Killawee on July 21, 2023 at 3:39 pm

    Great video and tip!
    Patiently waiting tor you to show the new table saw!

  39. Jesse C on July 21, 2023 at 3:41 pm

    I really like the card scraper idea for the glue.

  40. Howard's Channel on July 21, 2023 at 3:41 pm

    I’ve been trying to justify getting a Lamello P2 Zeta for awhile to compliment my Domino. Might just have to say f…. it and order one. so nice. Great video. I also use some Rockler panel clamps that put 4 way pressure on the boards. Just another way of working.

  41. James Shavers Woodworks on July 21, 2023 at 3:42 pm

    You didn’t mention to check the cupping of each board and how joining boards together with the cup opposite from each other helps with bowing over time!

    Love your vids!

  42. Kevin Willingham on July 21, 2023 at 3:44 pm

    I hate to say it but…using a straight edge while clamping is actual a pretty good tip. Dammit Jason! You won this one 🧐

  43. Chris Diggs on July 21, 2023 at 3:44 pm

    15 minutes for a 2 min lesson

  44. Design Creations on July 21, 2023 at 3:45 pm

    This is a good one, Jason. This is always a topic in woodworking groups that seems to be almost as misunderstood as dust collection.

  45. Ben Marshall on July 21, 2023 at 3:45 pm

    This is a sham, he’s not even wearing shop flops… poser

  46. Andrew Shaneyfelt on July 21, 2023 at 3:45 pm

    This video is valuable on the don’t overtighten clamps lesson alone. Thanks, Jason!

  47. gbear056 on July 21, 2023 at 3:47 pm

    Genius. I’ve got dibs on Jason and Neil Pask when the zombie apocalypse comes!

  48. Mike B on July 21, 2023 at 3:47 pm

    Thanks for some great tips.

  49. Bruce Brandt-Spare Time Furniture Transformations on July 21, 2023 at 3:47 pm

    Awesome! I have learned that overtightening clamps is not helpful but you just solidified that theory! I have used cauls in some cases which helps the ends but still at times have issues with the center areas but I think I know why now and how to address it. Will it work as well without biscuits? Thanks for all your straightforward videos!

  50. Rhett Dunn on July 21, 2023 at 3:48 pm

    I just did almost the exact method in a glue up and thought I was a genius for it. Now I’m assuming it’s common practice 😂
