Good morning. I'm rebuilding an old swing glider. I have to replace (8) 1x4x4' boards for the seat and back. What type of wood would be the best? I do plan on staining it when I'm done. Any suggestions? Thanks.
For outdoor purposes there are various woods in all prices, and you can read about them on line.
It also depends on where you are located.
A naturally rot resistant wood like redwood or cyprus would be a good idea. PT would work, although it tends to be wet and may need to dry before staining. Use stainless steel screws with PT or at least coated rated for PT wood.
That said I have a swing seat made of common spf 1x4's that has been in my back yard for 20 years at least. I make a habit of cleaning, staining, sealing it and taking it in during the winter. I've had to replace board or two and make some repairs, but it is still going strong. I wouldn't have picked the wood, but the swing was made as a gift and I intend to keep it up.
I'm located in Wisconsin. The summers are warm and the winters are brutal. I do have the option of storing it indoors for the winter.
Redwod would be a good choice, and so would cedar. Reasonably priced and available almost everywhere.
Thanks for the information!
