[QUOTE=atmartin23;132481]Need some help
However, i've read that finger joints are mostly used for end to end not edge to edge. Is there a better joint to use for edge to edge? Perhaps use a doweling jig instead?
While the finger would look nice. It is a Waste of time in wood of the same species. And would be a real pain on your job! Doweling would work, but as stated above, one mistake and it's OS. The tongue and groove is a good choice. Problem is most sets aren't made for wood that thick. And if you buy the bit, will you ever need it again. What I do in these cases is use the old floating tongue. All you need is a rabbit bit or even your table saw. Cut your 3/8 or 1/2 groove in each plank. cut a spline to fit and glue it in the groove. Remember to not make it too tight, leave a 1/16 or so for the glue.
Cut it twice, and it's still too short!
