I live near Portland, OR and am an avid outdoorsman and intermediate level woodworker. My projects include several Devlin stitch and glue boats designed for duck hunting and fishing the Columbia River. I’ve also built scale models of my grandson’s school for a play house and a Walter Jordan boat cradle.
I’m in the final planning phase of a Western Red Cedar Adirondack chair project using the Lee Valley plans and finishing with multiple coats of Cetol 1/ 23 as used by the folks at thebestadirondackchair.com.
I’m undecided as to using wooden plugs to fill countersunk screw holes or simply leaving the screw heads flush with the surface. Having used plugs in the past, I really like the finished appearance they present, however a question has been raised regarding their use in outdoor furniture.
A close friend who is a professional wooden boatbuilder is sceptical about the use of plugs in exterior furniture. His concern is that, due to the fact that wood will “move” under different moisture conditions, the expansion/ contraction of the plugs and stock may cause issues. Additionally, once the screws are covered, they become inaccessible should any tightening become necessary over time.
On the other hand, one of the folks at Woodcraft suggests that plugging and using Titebond III is better than not plugging.
I have seen a chair with plugged holes that was left unfinished and has become VERY loose. In order to assure secure fastening, my plan would be to use Titebond III in conjunction with the SS screws.
The plugs would be made with the same wood, possibly from the same board if that would provide any additional measure of common stability and be installed with the grain running in the same direction as the surrounding stock.
Any thoughts, opinions, suggestions would be much appreciated.
