Using Splined Miters in Frame-and-Panel Construction
Cutting the grooves for the splines.
Next, machine the spline stock, making it wider than the
spline groove is deep. Resaw the stock so that it's thicker
than the spline groove. Final dimensioning is done on
the thickness planer. Once you are close to final thickness,
plane a little off at a time and trial fit it until it
slides in with just a bit of friction. Cut the stock into
pieces oversized of the spline grooves.
To glue the splines into place, I use a thin applicator
so that I can get the adhesive into the mouth of the groove.
I also apply a little to the edge of the spline. Work
quickly before the glue causes the wood to swell. You
can lightly tap the spline into place using a small hammer.
Ensure all the excess glue is squeezed out and the spline
is set all the way in. You can use clamps to ensure a
tight joint.
Once
the glue is dry, trim off the excess spline stock
using a flush-cutting saw and finish with a hand
plane and scraper. Use a cabinet scraper to dress
the front and back of the miters. I also like to
use a cabinet scraper to remove the planer scallop
and saw marks from the frame. Rout the outside profile,
sand and finish.
