I'm building a deck. The basic shape is a rectangle. It's about 28.5
feet long, 17.5 feet wide on one end and 4 feet on the other, and the
angled side is about 28 feet. The angle works out to be roughly 26
The question is this what is the best way to cut the 26 degree angles
on the 2x6 joists. Because my circular saw and jigsaw won't do those
angles (at least not that i can see) I figured I'd have to do my best
with a sawzall. Anyone have an idea what the best way to do this
I thought I would snap a chalk line on the top of the joists and make
a pass with the circular saw (that should give me about a 2.5-3" deep
cut) and then complete the cut with the sawzall. It seems like there
should be a better way.
I'd appreciate any ideas.

I think you are saying that you have an angle of intersection that
reads 26 degrees, making it too steep and long for your saw.
If that is indeed the case, mark the top of the joist with the cut,
then transfer that mark over to the bottom. Cut the top with a
circular saw with the board on edge, then flip it over and cut the
matching cut to finish off the angle. This only takes another few
seconds, and with something that small you will be finished in no
Note that the really long cuts that leave the long thin points are
notorious for their weakness. Since you cannot use a joist hanger on
this type of cut anyway you need to think about alternative methods.
I usually blunt the point by about 1/2" to 3/4" of an inch depending
on how shallow the cut actually is as it seems to make it less easy to
splinter off. (This may be in my mind, but I do it anyway.)
Underneath these long thin cuts, it is always a good thing to put a
I agree with the circular Saw. My answer is to cut across the top first,
that way I have a 2+ inch cut on my line, then I set the saw in the cut
(unplugged) and set the angle on the plate. If the blade is not long
enough, I cut from the other side as well ( I have several angled decks
around my house and out building).
I cheat with fasteners - using a 6 inch long landscaping screws to put
the outer edge on the deck. This gives me enough of an anchor to avoid
using anything else. The oldest deck is more than 19 years old and I
have never had a problem. We had to disassemble a deck to remodel the
kitchen a few years ago, and all the angle cuts were in good shape and
the framing in great shape. After we finished I built the deck in a new
configuration, again with lots of weird angles.
OBTW, I lay the deck boards and then clamp a straight edge on them as a
guide for the circular saw, when I need to cut angles on the deck boards
I am not a professional carpenter or deck builder, so others may have
better ways of doing this, but this is what has worked for me.
A couple of cautions:
1) know where your body is when you are cutting up or down on installed
boards. I prefer to cut from the top down. I really want to know where
my legs and toes are.
2) The saw will get heavy and it is no fun to bang it into the ground,
if you are not doing this daily, take your time, getting hurt can ruin
your whole week.
Best of luck

On a circular saw, you can set the angle between the blade and the joist to
whatever you need. You would set the
angle between the blade and saw base to suit. Then you cut with the saw
base riding on the long side of the timber.
You can also set the angle on a table saw.
You can try to set the angle on a jig saw, but the cut would very poor.
You may be able to use a reciprocating saw, but the cut would be extremely
My choise would be a table saw.
My second choise would be a circular saw.
If I had neither of these, I would buy one because I don't believe that I
could do the task
reliably with either of the other two.
Circular saw, just need to cut across the face and not the top as you
describe. The base on the saw can be tilted over to probably 45
degrees, at least every circular saw I've seen. So if the joists are
in place you will be cutting down toward the ground.

Make the cut parallel to the 6" dimension with a circular saw having
the saw sole plate set to the angle.
Just to be a shit disturber, you realize that you will have a very
Suggest you add a 2x2 cleat to the bottom of the rail, then notch the
angled piece as req'd to provide added shear strength for the angle joint.
More work, but much stronger.
