New User to this group ... tired a couple of searches and couldn't find an answer ... sorry if I'm repeating a question that has already been addressed.

How would I use a domino to cut a hole at a 45-degree angle? I'd like to make what's in the pic, but without all of those pesky mortises and tenons...

thanks!
Matt

In that example, the answer is you don't.  The mortises are made at a 90 degree orientation to the reference face.  So the legs would have a 90 degree face.  And shorter 45 degree mitered pieces are cut first, then you will create the mortises at a 90 degree orientation to the mitered ends if that makes sense?
 
Good question as many users got confused about this type of angled joinery. See the image on one easy solution. For strength, you can use stacked dominoes.

You can mortise either piece first as the order does not matter. If you use stacked mortises, make sure you finish one row on both mating pieces first before changing the fence setting.

Yeah I see what you mean know. Got myself on the wrong path (don't own one, but its coming 😎 ). At the end they do something similar with the handrail. It's hard to see but is that also perpendicular to the reference face?

So the answer, is you can't?

BTW one could argue the mortise and tenon in OP example is also perpendicular?
