Domino Tenon Length Rule Of Thumb?

[darita]

I finally have a Domino XL and I have ordered the Domino sticks in 12mm and 14mm, along with the 14mm cutter.  I'd like to know if there is a rule of thumb to go by on the length of Dominos used?  I may be getting Domino stock for my Domino 500 as well, so this will apply to the smaller sticks as well.

Less than the thickness of your material.  [wink]  [poke]

Or equal to ... nothing wrong with exposed tenons - the SIPO ones can look attractive as a contrast to lighter timers too!

Total depth of plunges minus 2 mm.

28mm plunge + 28mm plunge = 54mm tenon

12mm plunge + 28 mm plunge = 38mm tenon

Here's an article from Chris Schwartz on tenon sizing.

Might give you some general guidelines:

It really depends on what you are building and the stresses the joint may endure.  You could have a 4x4 piece that is 2 feet long supported with a 1" tenon (1/2 / 1/2), or one with a 3" tenon or more.  It really depends on the forces.

If you can explain your project, I think others here can provide better advice.
