  1. Nyce……very well explained. Clear, concise and no BS.

  2. Well Explained !!! 

  3. And you don’t show how you actually DO IT…awsome.

  4. These videos may be getting old but they are still very relevant and
    informative. Thanks for making these helped me a lot.

  5. Great video! The marking the edges of the router is genius.

  6. Patrick is disapointed

  7. you need to get a camera with a clearer lense

    1. +BOBBY Well the video was made 8 years ago…

  8. I got a question on the collar chance…if I have a ryobi 1/4 can I replace
    it to 1/2 collar

      +Ernie Zamora Some routers are designed to allow either a 1/4″ or 1/2″
      collet, but most are not. If your router is not specifically designed to
      accommodate a 1/2″ collet, then you should not attempt to use one on that
      You should contact Ryobi to determine whether your specific router can
      safely utilize a 1/2″ collet.

  9. Was this recorded before or after the second world war?

    — Joking. Very informative

  10. But how do you round off the tenon??? This is the part I can’t find
    described anywhere.

    1. WoodWorkers Guild Of America

      +TheRacerRich The easiest way to do this to to use a hand saw and follow
      the plane of the shoulder and make a cut into each corner of the tenon,
      then take a sharp utility knife or chisel and tap it into the end grain of
      the tenon, cutting each corner off. Because of the cut into the base of
      the tenon that you made with the hand saw, the corners of the tenon should
      pop off easily and cleanly. This doesn’t “round” the tenon exactly to
      match the mortise, but it removes the corners and allow it to slide easily
      into the mortise. The cheeks of the tenon provide ample surface area for
      gluing, so it is not necessary to precisely match the contour of the
      mortise with curved tenon corners

  11. Great tip on marking the router edge to see instead of the mortise edge im
    a newbie with all this but ill use that tip.Thanks

  12. Good stuff. Like the marking of the router base as a guide…..simple but
    very effective. Thanks.

  13. great and simple video for everyone.
    Thank you!

  14. Buenisimo !!!

  15. why mark you start and stop points, and not use a start and stop blocks on
    the right and left side of the router edge, that way you can’t overshoot
    your mark and you can focus more on the routers rocking also you could use
    a block between the legs to give a bridge over the gap and more support
    with the extra distance.

  16. Using Woody Hyezmar’s Woodworking Bible, my brother is finally building and
    even selling some of his woodworking projects. Google him up

  17. you have mark for l to r But how do you sure That when you move you are not
    moving Up or down by Mistake ?

    1. WoodWorkers Guild Of America

      Hi, Hasmukh. It is important to keep track and constrain your movements to
      only the designated directions to avoid this type of mishap.

  18. Do you not have to first drill a hole to start the cut in with this type of
    router bit?

    1. WoodWorkers Guild Of America

      Hi Tim. No, plunge routers do not require a pilot hole. You can just
      plunge directly into the wood.
