I’m going to be building some 4 face large outdoor columns and I’d like to use cedar planks that are 18” on each side. My local supplier only has 12” width planks (again, rough sawn which is important for the texture).

Is finding 18” wide cedar planks a reasonable task? Just asking in case I’m about to go on a fool’s errand.

Depending on were you are, on the west coast lots of small mills that can cut any size you want, but the bigger it gets more likely to get cracks?

What cedar are you talking about?

Eastern Red Cedar is hard to find in large widths. Western, I think, is more available.

I’m in SW Ohio, and can source 18” width on some very nice stock locally. Costs a few pennies, BUT…

Won’t be at a Lowes, Home Depot kind of place. Check around to see who sells “specialty lumber” The place I go to has a web page, but this is not shown, you need to call the desk phone and inquire. I’ve found a lot of the true specialty stuff is that way though.

Finding any 18” wide plank is a formidable task, cedar maybe even more so.
If these are going to be painted I would strongly consider using a Hardi-board type product.

Have you considered making the columns out of other materials and then sheathing them with 5/8” cedar plywood house siding material which has a rough sawn appearance. Basically it is T1-11 siding without the groves. If you carefully bevel cut the mating corners it will look like solid cedar column.

If you could find the extra wide cedar boards you are looking for they are likely boing to be “center” cuts from the log and that will increase the chance of their splitting. It would probably be better to join smaller boards that are quarter sawn.
