I know it looks like it's supposed to be a 45 but when I cut both boards at 22.5 they didn't line up. I usually just keep tweaking the miter saw until I get it right but I want to do it quicker and easier.

Lay a board over the other board. Mark both edges where they intersect.

Lather, rinse, repeat

Bosch digital angle finder or by a kapex lol

Yup, or snap a line parallel at a couple inches off existing angle and find intersection. Or use a bevel square, or spend the money on a kapex and be happy life just got simpler.

Agreed, first thing I thought of when I saw the picture. Just make sure you have your spacing between the boards before you mark it. A 16 penny nail works great for this...

Beat me to it.

You could also lay long board in place, & mark straight edge to the corner of the upper deck, cut, & mark second board with 1st cut. Basically aim the cut at the upper deck corner for the first cut.

I don't get it.

I thought cutting miters is basic carpentry 101, is it not?

:huh:

 

[Warren]

I don't get it.

Lay a board loose going each way with one on top of the other. put a tick mark at each edge where they intersect. Connect the dots and....


VOILA!!

good googly moogly.....

Not really my thing, but it looks like one could even lay a board on the ground and use the concrete control joint as a guide. Mark it, take it to the saw, swing the blade to match it up.

Or how about this: lay all the boards on one side of the steps. Use a vertical laser level to line up your straight edge to mark 'em all. (Make sure the beam lines up with the control joint and the top corner.)

Laying one board over the other didn't seem too accurate.

Why do you think that? It is a good place to start. You can buy fancy angle finders, or you can stick with the basics.

Its not a 45 because where the deck boards actually meet is not the same point as where the corners on the skirt boards meet. For cryin out loud I can see that from my house...

 

[DuFast]

I knew how to get it close and then adjust the miter saw to get it exact. I just want to know how to get it on the first try and the boards fit tight all the way down the miter

 

[m1911]

And while you're at it, add a few more stringers in there...

 

[jaydee]

the best way is to fit the miters

We can't tell you the best 1st try w/o being there.

And pretty sure we all would fit the miter / or template the angles.

good luck

Guess I shouldn't be on this site.

Each joint will be a different collaboration to get to the 45 degree angle. Since the out lying point is off the point of the deck it will drift one way or the other. So it could start out 23/22 then go to 21/24 and so on... Finding common ground from the starting corner and scribing a line out to the edge of the board between the 2 stringers may help.
