Cut underside mounted panel with circular saw!

[VillaAnna]

Hi!

I'm almost done with the paneling on the house and I'm planning to trim the underside of the panel with a circular saw. Both the panel and the batten are installed. Does anyone know how the pros usually do this, do they mount a panel board to guide the circular saw? How do they keep it straight if multiple boards are needed? Anyone with experience in this who can give a couple of tips?

Have a nice weekend!

Empirically, you cut all the boards beforehand since the length is the same, and if it's for your own space, you can ensure that the end grain is properly primed for installation.
But now that you have already installed the panel, measure down from the eaves and mark in two or more places, then use a chalk line to get a straight line, or use a simple laser that can be bought almost anywhere for a few hundred.

Don't forget to bevel cut so that water running down the façade boards drips off and is not easily absorbed into the end grain. Also, soak the end grain thoroughly with oil before painting.

Several construction companies and house manufacturers have stopped cutting drip noses.
It seems that new findings have shown that a straight underside dries faster.
However, the most important thing is to oil/prime and apply a finish coat to protect the träta.

As the above says.
Cut straight and soak the end grain with oil, prime and paint.
Screw on a stop, a board that the saw can rest against and it will be good.

Do you have a source for that? Why would a straight cut dry faster? What's the mechanism in it?

Hello!

I'm about to finish the paneling on the house and plan to cut the bottom of the panel with a circular saw. Both the panel and battens are mounted. Does anyone know how the professionals usually do this, do they mount a panel board to guide the circular saw against? How do they keep it straight if they need multiple boards? Anyone with experience in this who can give a few tips?

That's how it was done in the past at least. After all the paneling was mounted, they nailed one or more boards along the bottom edge and sawed a neat finish on the panel. A suitable angle for water drainage is said to be a 17-degree bevel cut. (Mikael?) Don't believe those who say it works just as well to cut straight!

I screwed in 45x45 regel/ar along the facade side and tilted the circular saw, then it was just a matter of holding firmly against the regel and the edge became perfectly straight.

After that, the end grain was oiled and painted in stages.

Of course, you set to 17 degrees and of course, you place a board horizontally and cut afterwards if you want a straight cut.

 

[AndersS]

Do you have a source for that?
Why would straight-sawn dry faster? What is the mechanism in that?

What is said is that on a straight surface, less water stays and is distributed over the surface, while on a drip edge, as it sounds, a drop stays and takes longer to dry out. The drip edge was originally intended to lead water drops away from old stone foundations where the panel often lay close to the foundation. And where one also used traditional red paint. But as mentioned, there are likely to be different camps on what is best. You will have to search more on the internet, and there are probably threads here on the forum as well. I got the information from a well-regarded construction company in the area, where their carpenters have been instructed not to cut drip edges anymore.

Addition: Do it in the way that feels right for you and focus on the painting of the end grain.

It's probably just something people do nowadays to save time when putting up paneling. That it's the same at both ends so that it can just be put up.

 

[VillaAnna]

Lovely! Many great tips and explanations!
Unfortunately, there's a storm today so we'll have to build indoors today!
Have a good weekend everyone

But sawed wood still has an up and down...feels better when water flows with the grain on the fibers...

All paneling must still be cut and so it doesn't actually save time.

It feels like mixing freely...
Less surface area, okay yes that's true
Dries faster, why is that? The entire surface is exposed to the same drying heat/temperature.
The whole argument feels backwards, why would a drop linger longer when there's a sharper edge...
It feels like nonsense to save work...
