Best way to do end to end joints in 4 x 2 ? In other words to make 2 x

I was thinking either lap joint & glue & bolts or those spiky washer
things - joint doesn't have to be in line, just resist deflection. Timber
on edge.

Any thoughts?

A scarf joint sounds appropriate, using plenty of glue and a few nuts
'n' bolts.
You will lose a bit of length though, because of the overlap.
It was good enough lots of years ago for extending telegraph poles,
and there's a fair bit of stress on them...
