How to plane really wide boards

[BjörnbärsBjörn]

Hello!

I needed to take down two large beautiful pines on the property.
I rented a mobile sawmill and cut a bunch of monstrous boards that are 400-600 mm wide, 40 mm thick.
I'm planning to make a patio/deck.

They are now neatly stacked for drying.

So to my question: How on earth do I plane this once it's dried?
(Difficult to find a product/company that can handle these widths)

Could an alternative be to build the deck with countersunk screws and then use an electric planer to remove the worst?
After that, go over it with a floor sander?

Larger woodworking shops should be able to handle the width, otherwise they likely have a drum sander that can do it. You also have two years to find a used machine and then you just sell it when you don't need it anymore.

You can build a sled for a larger model router. A ladder, very straight plank or similar can be used as a guide.

This is how it looks in practice if you haven't seen a sled with a snow blower. Welded from some regular L-steel.
