Where to find 1" square pressure treated balusters/spindles?

Hello. I need to replace a couple of damaged spindles on a porch railing. The existing spindles are exactly 1" square with the sharp square edges (not rounded) and 32" long. These are just plain square spindles, no turnings or other decorative work. The thinnest (?) pressure treated spindles available at local (Chicagoland) big box stores, lumber yards and decking supply stores are 2x2s with rounded edges.

I am trying to avoid having to replace the entire railing (there are two of these) just for a couple of spindles. Any help regarding where I might find 1" (exactly) square wood spindles in Chicagoland or online is much appreciated. Thanks in advance.

 

Rip what you need from 5/4 decking boards.

 

Thanks for the suggestion, Wirepuller38. But I don't have the tools (table saw, circular saw etc)

 

Do you have a friend/neighbor with a table saw?
I've never seen 1x1 pt for sale and assume they will need to be ripped from larger stock.

 

Thanks marksr, I will look into table saw options. I did find 1" square 36" long pine dowels at Home Depot. Edges are not rounded. I wonder if that's what they used on the railing 35 years ago when the house was built. The rot was not much, just at the bottom tip. Does an untreated pine dowel work if properly primed and painted with oil-based paint?

 

Pressure treated is always best. Primed and painted pine can work but sometimes they will get some type of fungus rot and I'm not sure if there is a way to prevent that.

 

And if you did they would probably warp so bad after a couple months they would be useless.

By a piece of composite decking, rip it and be done, forever!
