Domino Alignment

[Nash]

I plan on building some cabinets with fixed shelves and would like to use domino's to attach them. I use the domiplate to center the domino's on the end of the shelf but i'm trying to figure the best way to center the domino on the side of the cabinet considering there isn't anything to reference off of because its in the middle of the board.

I designed something I call the Tomiplate which will do exactly what you want to do! It uses the LR32 system with some additional parts that attach the Domino 500 unit to the LR32 plate. This allows the woodworker the ability to install dominos at precise 32 mm spacing if desired. In your case it would facilitate repeatable positioning of the domino in the center of your shelf each time. On my first trial run test of my device it worked very well. Here are some pictures of my invention.

The beauty of the Tomiplate lies in the fact that it can be made for a very low cost and uses the LR32 plate without requiring any modifications.

The simplest way I've found to accurately locate fixed shelves in the middle of the panel is to clamp a guide rail across the panel so that the back edge of the guide rail is located where you want the bottom edge of the shelf.  I then locate the domino (holding it vertically) using the pins against the edge of the panel and the push the base of the domino against the back edge of the guide rail.  Very quick and easy and very accurate. 

When you cut the slots in the edge of the shelves, be sure to reference the base of the domino against the bottom surface of the shelf.

The centre of the mortise bit to the bottom of the Domino measures 10mm (IIRC). Clamp a piece of wood perpendicular across the cabinet side 10mm below the location of the desired mortise and use it to register the Domino with the fence in the up position.

Fred posted more or less the same method whilst I was writing my reply!

All very nice suggestions thank you.

Hi Nash,

I am just cribbing an idea someone else here posted (I could not find the original thread) but it basically uses the shelf and side material to align the dominos. The photos show the basic setup using some scrap I had handy.

First lay the shelf flat on the side panel, aligning the top of the shelf to where it will ultimately fit on the side panel. Clamp the shelf down at both edges. In my photo the thin scrap represents the shelf, the red line is the top edge:

Mark where you want your mortises on both pieces, the lay the domino on the side panel, align to your marks and plunge into the end of the shelf:

Next reverse the domino, hold it against the shelf and plunge into the side panel:

Since the bottom of the Domino itself is presses against the 2 surfaces that will match up it automatically spaces both rows of mortises 10mm from the top of the shelf.

Hope this helps.

PS - welcome to the FOG.

I don't understand how this thread didn't blow up after you posted this. Did you post about it anywhere else on the forums in any more detail? I think this is brilliant and am going to try to see if I can wrap my brain around you did it. I have a df700 and would love to have this kind of setup. This is, without a doubt, WP OTT material.

On YouTube, Half Inch Shy has a video on mid-panel joinery with the Domino which might be helpful. It's his video #71.
