I'm looking to build an outdoor cedar barrel sauna and was thinking
tongue and grove. I looked on manufacturers website and it seems that
they use a "ball and socket" type joint to join the staves together.
Anyone know where to purchase a set for grooving 1" or 1-1/2" lumber?
I've seen plenty small bits on Ebay and the like but haven't found
anything for 1-1/2" height?
