I have built a jig with a 1:12 taper. A good stiff back plank and two
planed and sanded tapered ramps securely mounted to the back piece to
make a valley for the thing to be scarfed. I then have a sled that I
mount a router on. The scarfs are very accurate and can be repeated lots
of times if necessary. So a few practices on scrap wood are easy to get
the best technique before you attack your very expensive good wood.

I have been very pleased with the results although it is a lot of effort
to build the jig. I have used it a lot for various jobs including a
rubbing strip involving 4 pieces of wood.

There are many different ways to cut scarphs. For spar scarphs, jigs
that create a ramp for a long handplane might be the easiest way.
For spars, you want at least 12:1 taper.

I have seen wood scarfed for wood mast construction where there is a long
joint made by overlapping two pieces of tapered wood. Can anyone tell me
how you physically create the long tapered joint? I have been
thinking of
using a thicknesser with multi passes.
