What Does a Jointer Do? – Ask Matt #13

A jointer is a very important tool in a woodworking shop. Its job is to set the foundation for all future work you will be doing with a board. Being able to properly mill a board flat and true is a fundamental task in woodworking because flat work pieces lead to more precise and consistent joinery in your projects.

    WHY is the title Jointer? You show a planner?



  2. George Cox on December 29, 2021 at 8:00 pm

    They are not in the same plane. Their surfaces are parallel.



  3. DOME KNOCKA on December 29, 2021 at 8:02 pm

    Damn didn’t think I needed another fucking tool. This God damn hobby I swear..



  4. Odise Carr on December 29, 2021 at 8:05 pm

    did the question come from Perkins builder brothers ?



  5. Afnan Khokhar on December 29, 2021 at 8:06 pm

  9. ymapo on December 29, 2021 at 8:08 pm

    What is the name of the glue jar that he uses at 12:22? Where can I get it?



  10. Garrett A on December 29, 2021 at 8:09 pm

    How do you deal with a board where the facing edge has damage or is not true (parallel) to opposite facing edge?
    Maye use Jointer to insure reference edge and then table saw for opposite edge?



  11. Kyle Jones on December 29, 2021 at 8:11 pm

    Thanks Matt



  12. Ted Tolentino on December 29, 2021 at 8:13 pm

    Thank for this video. You answered my question about the differences and uses of these wood working tools that I never really understood. I’m just getting into woodworking as a hobby.



  13. Kenneth Hopson on December 29, 2021 at 8:16 pm

    Matthew, there is another jointer. It’s a simple edge with a saw that will cut into the board. You set the boards together and press so the saw cuts into the edge of the board to place a wafer into then you make sure that you have the cut from the sawblade in both boards in the same way. Place glue in the holes and stick the wafer or biscuit in the hole. Then glue the other board the same way and press it into the other board to bring a marriage to the boards so they become one.

    2 million views…..I guess we wanted to know this stuff…



  15. SmithMiddleGa on December 29, 2021 at 8:18 pm

    Great lesson! I’m blown away at the effort given to properly explain the purpose and use of these tools. Thank You



  16. Pork Chop on December 29, 2021 at 8:18 pm

    Very informative. My bro just bought a planner and we both looked at each other and asked, so what is the jointer for? I thought it was only for the side of the wood and not the face. After we ran planks on his planner, know I must have one. After watching this video, now I must also have a joiner.



  17. Daniel Hinds Sr on December 29, 2021 at 8:19 pm

    Wow great video thank you.



  18. Dave Blevins on December 29, 2021 at 8:19 pm

    Thank you Matt. 👍



  19. Leonard Hirtle on December 29, 2021 at 8:20 pm

    Very informative. Nice shop.



  20. Squidge on December 29, 2021 at 8:20 pm

    Well explained!
    … but dangerous use of the machine, putting your hands over the blade, ESPECIALLY when the safety cover was off! Beginners should NOT copy this technique!



  21. Kenneth Hopson on December 29, 2021 at 8:21 pm

    Do you know that boards warp and bend from the pull of the moon just as the ocean ebbs and flows from the pull of the moon?



  22. MathGuy on December 29, 2021 at 8:24 pm

    Hi Matt, what jointer and what planer would you recommend to a your basic amateur woodworker? Thanks in advance.



  23. Wikid on December 29, 2021 at 8:24 pm

    What good is a planer without a jointer and vis-versa?



  24. MinHongJi woodstudio 솔터공방 on December 29, 2021 at 8:24 pm

    hi…I made a safety guide after watching your video. Thank you for being an inspiration to me.



  25. Frank Hurley on December 29, 2021 at 8:25 pm

    Hi ,Frank Hurley from knotty ash, UK.
    I have in the past used a planer thicknesser to produce boards for kitchen cabinets etc.
    When you joined yours for a panel, I see you did not mention reversing the arch of the grain to prevent warping.



  26. Das Plague on December 29, 2021 at 8:27 pm

    Great video 💯



  27. Backup218 on December 29, 2021 at 8:30 pm

    why the downvotes it good info ??



  28. Lime on December 29, 2021 at 8:31 pm

    You can also square the end with a chop saw now that the bottom and side are trued up. The best way to view a jointer is as a support tool, it doesn’t do much by itself but when you use it with a planar, a table saw, or a chop saw, you massively increase the precision of those other tools.



  29. Gary DeRuiter on December 29, 2021 at 8:32 pm

    What if I have a electric hand planer would you buy a jointer first then



  30. Mateo Maderas on December 29, 2021 at 8:32 pm

    The planes are Parallel. You’re welcome 🙂



  31. oopie yoho on December 29, 2021 at 8:33 pm

    What does a jointer do? WELL IT MAKES JOINTS, MAN> WOO WOO LETS PARTY!



  32. Stephanie Willingham on December 29, 2021 at 8:36 pm

    thank you too very much!



  33. Colin Peddle on December 29, 2021 at 8:36 pm

    Love your candidness and to the point style. Quite refreshing in a YouTube world filled with polish and fluff.



  34. HoldMyBeer on December 29, 2021 at 8:38 pm

    Thanks for this informative video! 🙂 I still do not get where the word "jointer" comes from … ^^



  35. cc sports fan on December 29, 2021 at 8:39 pm

    excellent



  36. Paul Benjamin on December 29, 2021 at 8:40 pm

    well done, to the point and truly informative



  37. Honeydrop Farm on December 29, 2021 at 8:40 pm

    I like how you show the results of doing it wrong before showing us how to do it right. Thumbs up



  38. Steven Rowlandson on December 29, 2021 at 8:41 pm

    The real challenge is to use a #7 hand plane with a razor sharp iron and plane the edges and put some glue on the edge and rub the two edges together until they are properly aligned and cannot move due to a suction and no need for clamps…. It takes practice….



  39. Garrett A on December 29, 2021 at 8:43 pm

    This Jointer is HUGE. very nice.



  40. Rod T on December 29, 2021 at 8:43 pm

    I have zero experience, and after watching your great video one question comes to mind, after completely removing all inconsistencies and getting one board flat on all sides, how do you know how much material you have removed so that the next 10 boards (for example) end up being the same exact thickness, since you will have to remove different amounts of material on all boards to get them all nice and flat, would you have to run all of them through the planner and set the thickness to match that of the thinnest board?. As I mentioned, I have zero experience. Thanks!



  41. Garrett A on December 29, 2021 at 8:44 pm

    how do you spell that … coplanarity? love it…



  42. ABDULLAH K on December 29, 2021 at 8:46 pm

    Well explained. Thank you.



  43. Simon's Stuff on December 29, 2021 at 8:46 pm

  48. Randolph Spot on December 29, 2021 at 8:53 pm
