Domino spacing
« on: January 06, 2019, 02:30 PM »
Hello all, new member with a new domino 500

When using the domino 500 with the edge stop dogs is there a way to use the edge stop dog, like a stop pin?  I thought i had seen reviews showing this, but maybe the reviewer had the older model with pins.

Anyways without this, am i stuck marking the location of every domino i would like to place?  I have the extension wings, but the closest they go is 100mm, and make this tool feel less elegant than the design.

If you don't already have them then try the Cross Stop QA-DF 500 and the Trim Stop LA-DF 500.  $78 dollars each and they go a long way toward relieving you of the need to mark.

I have the cross stop, But only able to get the domino's space every 100 mm.  Is there a way to space them every say, 50 mm.  I would assume that more domino's would be stronger?

Intuitively, I wouldn't believe that closer spacing is stronger than farther spacing after a point. To create those mortises you are taking out solid wood.  If you do that enough you're making something that can be levered and cracked.  Also, if you have that many dominos, you likely want to use a middle setting on at least some of them; which means you are creating more voids to have no structure.  With the 100mm spacing, you're already about ~1/6 of a joint being dominos.

If we are talking about builtins, unnecessarily stronger.  And it unnecessarily complicates assembly.

On 24" deep frameless base cabinets I go the full 200mm on the cross stop.  That gives me 4 dominos per butt joint and that's enough for built-ins.

building built in closets with melamine boards.  Finally gave myself a reason to buy a domino.

I am no expert nor do I do this professionally, i was just thinking that a domino every 2-3" looked about right, lol.

if 200mm gets the job done, then every 100mm should be strong enough.

If I’m joining long grain to long grain, I think of Dominos as primarily providing alignment along the top (reference) surface. I use an 8 to 10 inch spacing. I use pencil marks on both boards, cut narrow mortises on one board and medium mortises on the other board. I normally use 5mm tenons on 3/4” wood.

If I’m using Dominos for a joint that has to withstand structural stresses, I try to balance Domino size and placement against removing too much wood.

The biggest tenon I’ve used is the 14 mm for a bed frame.
