Hello, I have a glue-laminated beam 110x400 that I want to cut a "half-moon" in the middle of the beam. Does anyone have an idea how I should cut it? Jigsaw blades are too short, and while it is possible to order extra long blades, maybe there is another method?
 
How long is the piece? Is the thickness to be cut 110mm? When it's that thick, I think there is a risk of the saw blade wandering even if you get hold of longer blades. If the piece can be handled, I would suggest a bandsaw.

The beam is 4 meters long and the cut I'm going to make is about 1 meter in the middle of the beam, so a bandsaw won't work. Well, maybe it would with a large bandsaw and a couple of people.
 
Bow saw and hand sawing. There are models where you can turn the blade, maybe called a round saw, or a coping saw.

With a good axe, it goes smoothly... if you can use the axe, that is. Unfortunately, there are people today who can't.

Why should you have a notch in the middle of the beam? It weakens it quite a bit.
 
No, it doesn't work with a bow saw, I'll try to draw a picture of how I'm thinking.
 
Tiger saw.

Chainsaw?

If the finish of the cut isn't important, I might have used my electric chainsaw.
Here, as with the axe, it's important to know a bit about how to handle the tools.

A reciprocating saw, which was suggested here, isn't too bad either.
The finish is a bit rough there too, but at least a class better looking than with a chainsaw. :)

A saw like this is probably recommended then A traditional bow saw hanging on a red wooden wall, suitable for woodcutting projects. pm me if you need to borrow one, and we'll see if I have one in the right size..
 
There will be a wall between the house and the garage and there will be posts on each side of the "halvmånen". I had a beam left over, so the wall will match the style of my deck construction.
 
Yes, I've also considered a reciprocating saw, will give it a try today. Will get back with pictures.
 
Saw strips/slices that you break loose and then sand for the finish?
Or drill holes along the profile and chisel away between the holes?

Now I'm curious!

  1. What purpose is the hole supposed to serve?
  2. How big should the hole be? Picture/sketch?
  3. Is the weakening of the beam taken into account? There must be a reason why such a strong beam was chosen.
 
Hello, there will be a door that is rounded at the top and goes up a bit into the beam. The reason why the beam is so thick is because I had it lying around at home. I have a door in the wall on the other side of the house that is rounded at the top, so it might be good to also round off the door between the house and the garage. There will be no load at all on the beam.
