Super wide mortise

[Jed2]

Please accept my apology if this question was posted before.

Was wondering if the domino machine can cut multiple 20MM mortices to create one super wide mortice 50+ mm is width? ( yes I know I have to create my own specialized dominos )

Easily.

Mortises wider than 3-1/2” can be problematic due to seasonal wood movement.

Wouldn’t multiple dominoes be an easier solution?

Like Tom said, it's easy. You can overlap cuts with very good alignment. You do have to calculate the space between the 2 (or 3 or whatever) cuts and lay out centers so your total mortise length is consistent. Do the math, but then do a couple test pieces before you cut your actual workpieces.

Here's video on making a wider than standard Domino, it starts at the 1:25 mark.

I forgot to bring a router to a job. Had to plow a groove in the bottom of a 36” wide door, grabbed the Domino, made the plunge, just walked along the door. Was a little noisy, other than that it work really well.

A very shallow groove? I wouldn’t expect that to work if more than a bit diameter deep.

15 mm deep.

Very clever solution!

I not to long ago made a crib. It had slats on the sides and a wood frame with slats. I used my DF700 locating pins and a wood jig to locate the pins:

Thread 'Wider Tenons Using WP Half-Round Router Bit and DF700 Trim-Stop'

May 2, 2024

I’m making a crib and had an idea to use the new WP half-round metric bits to make the slats the tenons instead of mortising a smaller Domino into the end of the slats. I made a jig that attached to the rails with pin nails and plunged the mortises with one trim-stop setting and then the second. Ha - I’m getting old so have to work smarter so made trials on scrap to make sure this would work. I was afraid making two mortises by hand using pencil marks would not be accurate. This worked out well!

Here is a very simple jig to make precise wide mortises with a Domino 500 ..



Making a 10mm wide mortise. Set the one jig on the left end of the mortise and mark the centre line for the Domino ...



Now mark the right end ...



Anything uncut in the middle is simple freehanded.





Early version of the jig making loose tenon joints for a bed ...

I like this approach. Thanks for sharing your idea.
Simple is always a great approach.
