30-45 deg domino-ing

[pettyconstruction]

Ok,
So I have a question for you domino pros.
I want to put some dominos on a piece of wood that is joined with a 30 deg.or 45 deg.cut. The dominos would have to run inline with the piece,not at the angle.
Make sense?
Say taking 2- 5' boards to join and make 1-10' board.
How would that be done?

My thought was to put the dominos in the board,then cut the bevel in the piece.
Problem is the domino would seem to be to short.
Thoughts? Ideas?
Thanks,Charlie

I would have a square end, cut the domino deeper and then trim at the angle. How much deeper will depend on the board thickness and angle.

That was my thinking,but the domi may end up to short.
I'll have to test it in the morning,
Thanks,Charlie

Use the auxiliary fence on the base plate, set the main fence to 90º. The auxiliary fence will stop at the long point of the miter, the main fence references the face of the board. You will be plunging into air at the beginning of the plunge so set the depth of the Domino to achieve the desired depth of cut. You still may meed to trim the Domino tenon for proper fit.

Thanks for the replies,
What I'm thinking is to put 2 or more dominos in a 2x6,that is used for a rail cap on a deck. Trying to keep the boards from opening up.

If you are using multiple dominos what is the benefit of cutting at an angle?

Good point,and I did think of that one also.
I'll have to test it on a scrap piece.
Thanks ,Charlie

Use the longest Domino you can, install screws into the Dominos up through the bottom of the rail, it will act as a draw peg.

Use Sipo Dominos or make your own out of rot resistant material. Epoxy will help seal the Domins and make a strong joint.

Cutting the boards to be joined at an angle can make the joint less visually obvious. I suggest a test with a 15 degree angle to see if that is enough to get the desired effect. If 15 degrees is enough, then the long dominos should be fine. I assume that you will be using the Domino XL as the much longer dominos will be very useful. As I have stated before, using an XL can be an awesome, fun, exciting etc experience.

Putting in screws from underneath sounds reasonable. I have wondered if using 5/8 in brads when using 1x stock and the Domino 500 allows one to glue a joint, clamp it, nail it and then release the clamps without losing any of the joint strength. I believe this has been addressed before but my experience with the Search function has been less than joyful.

I've used 4 mm Dominos intersecting the main Domino as a draw peg.

That's a great idea,the screws from under.
I'll give it a try,thanks

I have built outdoor Ipe benches using Sipo tenons glued with 2-part epoxy. The tenons were pinned with screws from the underside. I did not release the clamps until the glue had time to completely harden. I think there has to be a fine balance between having a large enough pin to hold the tenon in place and not so large as to weaken the tenon.

Just so I understand,
Is one of those dominos put in after the other had the glue set ?
Meaning the second tenon is cut into the first?
Thanks,Charlie

Prior to the glue set, one intersects the other.

If you are using epoxy won't the wet glue foul the hot cutter requiring you to clean it quickly.
