how do you easiest make a notch in a post?

[JanneSjo]

I am going to set up a balcony railing with pressure-treated wood.

The balcony is about 1.5m deep and 3.5m wide.

I can't screw into the balcony floor, so I will screw a 70x70 post into the wall (wooden house) - wondering how long the screw needs to be to hold?

So, there will be a post against the wall, then a post in each outer corner + 1-2 posts between these.

I plan to use horizontal decking 28x95 between the post against the wall and the post in the corner.

I want to recess this horizontal decking into the post and here I'm wondering how to easily make a notch in the post?

I was thinking of trying my Bosch multicutter - but maybe there are smarter ways?

Do you want to make a notch in the middle of the post that is 28x95?
Not notch in on one side of the post?

For the notch, the multitool sounds like a good option.

 

[JanneSjo]

can't understand the concepts.

I imagine the horizontal board going from the side into the post a bit so deep that the board is flush with the post.

The notch in the post will then be about 50 mm wide, 28 mm deep, and 95 mm high (board 28x95mm).

I might also consider running a board along all the posts towards the yard, and then it will be a different notch across the entire width of the post, 28 mm deep, and 95 mm high.

If you don't have a multicutter, what do you do?

I'll try the multicutter tomorrow.

Does anyone have a link to a description of how to make a notch of this type?

And maybe other smart ways to attach boards and posts.

If you don't have a multicutter, use a handsaw and a chisel, and preferably a small mini belt sander.

A post like the one on the right I would track with the miter saw or plunge saw or ordinary hand circular saw and then knock off the piece with a chisel and tidy it up with the chisel if it was a matter of a few posts.
One can also saw a few extra grooves, reducing the risk of the chisel taking more than intended.
Set the depth on the saw being used to exactly right!

If it were just one post, I might just take the handsaw and try to act like a real carpenter.
(it’s not easy to saw straight with the handsaw :blushing

The post on the left is trickier.
I'm not entirely sure that was what you meant, but that's how I interpreted it anyway.

There, I would probably take out the Bosch multi-tool and saw the three cuts and then chisel.

I can't screw into the balcony floor, so I'll screw a 70x70 post into the wall (wooden house) - I wonder how long the screw needs to be for it to hold?

Well, a size of about 6x120-130 mm should work well. Pre-drill in that case in the post with a 5 - 5.5 mm drill. Do not use electro-galvanized screws, but hot-dip galvanized, stainless, or protect 4 (or whatever it’s called). Rust streaks on the posts are not nice.
You can also countersink the screw, drill through with a 5.5 mm drill, then drill with a 10-12 mm (or whatever is required for the head) a few cm in. Then you can be fancy and try to plug the hole with some form of purchased or homemade wood plug.

Thank you!
What great pictures just as I meant

I have another question about how to set/attach a glass pane between the posts - I will write it on the outdoor deck forum since it might be more of an appearance question - even though I need a smaller dimension of pressure-treated type trim - one would need a table circular saw...

another question - since I'm not screwing the posts into the floor but into the decking, I should have 2-3 longitudinal 28x95 boards from the wall post to the corner post - so that the railing doesn't come loose if someone leans against it.

will 60 mm decking screws or possibly 40 mm anchor screws be enough to fix the board to the post - or should I use through bolts, like carriage bolts.
