Just to throw one more thing out, did you orientate the grain of the splines so it ran across the miter rather than in the direction of the miter? If the splines were put in with their grain running the same direction as the line in the miter joint, expansion of the splines might pull apart a weak glue joint.
Those look real nice Shaney,that tool makes a nice round Dowel.
I use a LN dowel plate so the dowels I make are only good for drawbore joints.Mine always come out wormy looking since I have to start with a rived wood.
We have a horror freight nearby.I went in there to see what the deal is.All I can say is that place stinks what on earth can make a place smell like that.
Somthing must be wrong with our store I couldn't handle the smell long enough to see much.
