    Great tips!!! I am a noob when it comes to woodworking and you explained things very well. Also, nice shirt! I go there every time I get to KC, love the original ’Oklahoma Joe’s’ lol

    Question: you don’t address options for storage like Pre-coating the board piece with a universal sealer /base coat .. would sanding and doing a quick spray of shellac serve a similar purpose in terms of preserving the board , and making it “ready to go”? If you wanted to stain it you’d need to remove the shellac with a quick sand job to “take it out of storage model , but it would be ready for poly or paint right away .

    Question: To get better results as a beginner, is there a preferred measurement for the individual boards to be glued together? Like should I try to keep my strips in the 5" and under range or does that even matter?

    That veneer example was super cool and really shows how wood can move. with variable humidity.

  5. Jack Jamieson on January 22, 2023 at 3:14 am

    Great tips

  6. R M on January 22, 2023 at 3:15 am

    The whisper has spoken. Thank you for sharing your knowledge! It has helped my projects tremendously.

    He provided a lot of useful information. Thank you

    The logic regarding end grain orientation is flawed . (not my personal opinion, this is a century old observation and a time proven protocol) :
    1) even if a 36" surface was what is needed you WOULD NOT just use a 36" wide piece of wood if it (38")was available . You would break that board doown into 4-6 " ripped strips AND you would shuffle the pieces so as to end up with a continuity to the grain BUT you would reverse the ‘up’ orientation of every other strip .
    IF you examine the tops of decade old pieces of furniture constructed in this method you will find a perfect maintenance of flatness that has endured . (ALSO you cannot ‘flatten out a large surface that has cupped because this rule was ignored without the eventual cracking in the surface, much like gluing an end board tightly cross grain to a top will eventually fail due to unequal expansion of long vs short graining.

    That Joe"s BBQ though! mmmmmmhhhmmmmmm

  10. Elwood on January 22, 2023 at 3:17 am

    All wonderful tips thanks man.👍🇦🇺

  11. Micah Howell on January 22, 2023 at 3:17 am

    What a great video!! I wish I would’ve seen something like this 10 years ago!

  12. J. Allen on January 22, 2023 at 3:18 am

    This was VERY VERY helpful. I appreciate the effort you put into this. Thank you.

  13. Bujwids Decorative Woodworking on January 22, 2023 at 3:18 am

    Great video!!!🔥🔥🔥

  14. Roy Riederer on January 22, 2023 at 3:18 am

    My question is, would it be better to use many narrow strips or fewer wide strips of wood? I’m looking to make some 24 inch panels.

  15. PNW Grown on January 22, 2023 at 3:18 am

    Flipping fantastic video man. So informative and still not dumbing it down. I appreciate you

  16. Raliegh White on January 22, 2023 at 3:20 am

    Your opening statement was proven true for me right now… on my first project ever. 😂

  17. Mike Falkner on January 22, 2023 at 3:22 am

    This is one of the best videos on how to create flat edge-glued panels. Thanks for sharing.

  18. Eric Peltzer on January 22, 2023 at 3:23 am

    I’ve actually been doing this for a while with decent results, but it’s certainly worth watching every minute of this because experience has only taught me about 30% of these points.

  19. Reid Morse on January 22, 2023 at 3:24 am

    Great video as usual. I saw that the clamps were removed at 30 minutes to scrape off the glue. We’re the clamps reapplied and for how long? Thanks

  20. farrier ss on January 22, 2023 at 3:28 am

    Clamp stretcher. They are always a tiny bit too short

  21. Robert George Miller on January 22, 2023 at 3:28 am

    What the hell is that word "Aklah – mate" ?? It’s ACCLIMATE, pronounced like climate.

  22. Omar Ahmad on January 22, 2023 at 3:28 am

    Your work is always so beautiful

  23. Rocco Pietrofesa on January 22, 2023 at 3:30 am

    Thank you this is going to help me a lot.

  24. Amazon62 on January 22, 2023 at 3:30 am

    Hi, thanks voor the video. Question: do those clamps have a special name? When I search, I only get those normal everyday clamps. Thanks.

  25. TheGordog on January 22, 2023 at 3:30 am

    Thanks. Excellent practical advice as always.

  26. Lucas Johnson on January 22, 2023 at 3:33 am

    Had to keep rewinding because I got distracted by all the amazing stuff in your backdrops. Especially loved the "ban" hammer!

  27. SUPERWAVES on January 22, 2023 at 3:35 am

    How long do you leave piece in clamps?

  28. Rich Williams on January 22, 2023 at 3:36 am

    You can dye glue?! That great info.

  29. The Wood Whisperer on January 22, 2023 at 3:37 am

    Have a tip not covered in the video? Share it here!

  30. Paul Kramer on January 22, 2023 at 3:38 am

    good concise information. I’ve been working with wood for almost 60 years. All your points were well made, and not overly verbose. Of course us skilled workers get our own habits and preferences, but these were good. Because of glue improvements and changes, there are some different ways to handle things now, but basically, I’d agree. I appreciated the comment to wait a few days before sanding panels. I’ve often seen folks rush things a bit too fast and want to get that project to go together too quickly. I often have several pieces in work at the same time, so as to allow for drying to take place. I’ve seen panels where the biscuits used telegraphed thru to the surface because the panel was sanded within a day or two of glue up. Thanks

  31. poodelek on January 22, 2023 at 3:39 am

    Great video with lots of useful tips. Thank you
    Just one suggestion regarding tip no.9…. Instead of using a stretch wrapping I recommend putting panels in a plastic bag and seal it. It can be re-used which makes it much more environmentally friendly

  32. Samuel Rivera on January 22, 2023 at 3:40 am

    Does the rule of 45 apply with 4 way panel clamps? About two weeks ago I was helping a buddy of mine that is a carpenter, because he was making a table, and he has these 4-way panel clamps that he bought from rockler. They are similar to the ones that Woodpecker’s sells. He spaced his out 16 inches apart. I told him about the rule of 45’s. He tells me with these clamps he is allowed to go 12 to 18 inches apart. Is there any truth to that? When possible could you clear this up? Thank you

  33. Nikolay Pelov on January 22, 2023 at 3:40 am

    1 – use plywood
    2-9 – see 1

  34. pitot1988 on January 22, 2023 at 3:41 am

    Did woodworkers in the past use that many clamps for their projects?

  35. John Faustus on January 22, 2023 at 3:43 am

    That’s ~$450 worth of clamps at 8:09 🙂

  36. Keegan Brown on January 22, 2023 at 3:44 am

    I uuhhhhh should’ve watched this before I glued my panels down haha

  37. Todd Beaulieu on January 22, 2023 at 3:45 am

    This is possibly the very best, to the point video I’ve ever seen. Not only from you, but ever. I’ve been woodworking for … ten, fifteen years? I learned a lot here that I will apply.

  38. LV Q on January 22, 2023 at 3:46 am

    I learned a lot. Thank you.

  39. Fair Dinkum on January 22, 2023 at 3:46 am

    I know this is late but for me, the order I consider first is grain direction which isn’t covered here but is probably assumed everyone knows (but they don’t).
    I always orient my boards so I’m not planing against the grain if I need to plane.
    I only really worry about grain orientation (happy face sad face) if the end grain on all boards lends itself to this pattern for aesthetics where the end grain is seen, otherwise it’s pointless.
    So my preferred order is:
    1) Grain direction
    2) Grain matching
    3) Grain orientation (only if all ends have the same pattern)

  40. shayne sabala on January 22, 2023 at 3:49 am

    I’m new to all of this and I have to say, your videos are absolutely the most helpful of any videos I watch. I research to death, and never find so much useful information as I do in your videos. Thank you so much, now I need to go prop up a door panel I glued together this evening. Ha, keep up the good work and I hope you are rewarded, as you deserve it, sincerely.

  41. Carlos Cabrera on January 22, 2023 at 3:50 am

    This is a fantastic video. Wow

  42. Todd Harshbarger on January 22, 2023 at 3:50 am

    Very helpful

  43. midi510 on January 22, 2023 at 3:52 am

    Was picturing the 45° angle principal with a caul behind a thin board and how it spreads out the load/force.

  44. Ryan Watters on January 22, 2023 at 3:55 am

    Anyone else watch videos like this and get envious of anyone with that many parallel clamps? Those things aren’t cheap…

  45. Holland Custom Woodworking on January 22, 2023 at 3:56 am

    So much great information here! Thanks for sharing

  46. aakburns on January 22, 2023 at 3:57 am

    This is a very helpful video. Thanks.

  47. hawksstandoff on January 22, 2023 at 3:59 am

    What clamps are those?

  48. nod bod on January 22, 2023 at 4:03 am

    Well thought out and presented.

  49. Henry Rossouw on January 22, 2023 at 4:04 am

    Great to be reminded about these small little things that add up to huge problems in the end.Thanks for sharing.

  50. Cher M on January 22, 2023 at 4:05 am

    What if you get stain on then see it
