How to cut this glulam at 45 degrees

[Mikael_L]

I have this glulam beam in dim 115x315, and want to cut it at 45° according to the picture.
And it's quite important that it gets the right angle and relatively nice surfaces.

Tips on how I should go about it, thanks.

Circular saw from both sides and then hand saw for what you can't reach with the circular saw? The hand saw is probably well guided by the circular saw cut.

I would primarily go to a joinery or a sawmill and purchase the service. If I'm doing it myself, I would set the plunge saw to full depth and 45 degrees and use the guide rail to cut on both long sides. What's left in the middle, I would take the hand saw to. Tidy up with a sanding block!

I have a plunge saw with a rail.
And this solution is the best I have come up with so far. I draw and mark very carefully beforehand and then saw as deep as possible.

But is there anything better or cooler?

ps "exact" angle is more important than the surface, I think.

Cooler? Well, it would be a pentylstubin then
Feel free to add a few centimeters to the length when cutting the angle in case it doesn't turn out well, so you get a few more chances. Then cut the other (straight) end to the correct length.

if you build/manufacture a miter box (in metal?) with customized dimensions I think you would get an excellent result.`

And hand saw in?

 

[ArneTW]

And handsaw in?

Yep, that's what I was thinking. There is surely some Japanese fine saw that gives a good cut. How long a blade does a reciprocating saw have?

Was about to make a joke about the need for a new circular saw with a large blade, surfing on Makita's website and notice that the largest model only handles 90mm at 45 degrees, not big enough then. Too bad

Mafell has a tool:



But now I wasn't planning on buying one of those. It will probably be both easier and cheaper to take the beam to a workshop.

If the cut is to fit against another surface and look nice, the angle must be exact to fractions of a degree.

Take it to a carpentry shop, as has already been suggested.

 

[MathiasS]

eh, cowardly to skip a cut.

Use the plunge saw as planned and finish the last part with the hand saw. Cut the length on the other end so it's not as crucial where the difficult cut falls.

 

[elmont]

It's not cowardly to be smart, go to a snickeri.

 

[MathiasS]

I think the problem with cutting straight is slightly exaggerated. Before the jigsaw became common property, everyone could make this cut with the handsaw. Today, most of us are quite rusty with that tool, so you'll need some support. Either with the plunge saw as suggested, or with some support pieces to cut after. And, buy a new handsaw for this cut, and it will be easy.

Eh, I could make that cut with an axe and a blindfold.
