How many dominos for a kitchen base cabinet?

[griph0n]

I've been using 4 dominos and six kreg pocket screws.  I prefinish the plywood so only the dominoes get glue.  Too many?  Too few?  It's 3/4 maple ply sitting on a ladder base.  I tend to stray towards over building and have little love for sheet goods and no experience with this.  Seems to be fine, but I don't have the 5, 10, or 20 years to see how it holds up.

Are you using glue as well?  I use Dominos for strength and alignment, and as long as your cabinets are being held together well and parts are where they should be (flush, etc.), I would guess that you're okay.

Which size Dominos are you using?  Are you using pocket screws instead of clamps while glue dries?

I use 2 for joint and 2 #8 screws so it would be 4 of ea per side.

Yes I'm using the pocket screws instead of clamps.  No glue because of the prefinish panel.  It's a nice production method for a small shop.  I can completely assemble a complete kitchen in a day from a few 5 ft tall stacks of parts.

So you are using four dominos and six pocket screws per joint? Across about 20"?

Yes.  The bottom is a full piece and the top is a couple of 5 inch stretchers.

I generally don't use pre-finished plywood, so I get full use of a gluing surface at the joint of sides.  In this case, I use four dominoes and five pocket screws.  I use two dominoes and three pocket screws at each end of a stretcher, too.  When I use face frames, I generally use three dominoes and four pocket screws on each piece, spaced so they don't interfere with the dominoes and pocket screws that join the sides and bottoms.

Titebond makes a melamine glue which allows you to bond the cut edge of a melamine with the melamine-covered face.  I wonder how it would adhere to prefinished ply... Anyone know?

Don't know about the Titebond, but I just used the Roo Glue brand of Melamine glue to resurface a table covered with paint-finished plywood with laminate coated plywood.  Worked well, though technically you're supposed to scuff the finished surface for greater adhesion.
