  1. Why do you use a 3/8″ or .375 dado? a 4″ drawer side divided by .375 = 10.666 But you say and it appears to be perfect across the 4″ rather than having a smaller 2/3 piece at the end.

    1. 3/8 dado is actually .365 and the size of the fingers I make smaller which is around .360 If you add those up It will only be off by .01. I try to keep the video short and to the point and sometimes I have to make a judgement on editing. I hope this helps. Appreciate the comment and for watching.

  2. thanks for your training.
    Been away from wood working for 40 years..
    thanks for taking the time to teach the techniques that make all the difference

    Trying some finger joints tonight.

  3. Are you using the Forest Flat bottom box joint set or are you using multiple Forest Woodworker II #1 grind 10 inch blades?

    1. I use the Forrest WW II #1 grind which is the same as the box joint blade. For making 3/8 box joint I use their 8″ dado set. Hope this helps.
