The URL is UK, so unless you want to get on a plane right now, it might be out
of reach.  I have only made 9 Windsor style chairs and I did not want to invest
in a gutter adze.  I bought a small coffin smoother in cherry with a single (not
double) iron, made a compound radius on the sole and reground the blade to match
the sole.  The fore-and-aft arc is quite severe and the mouth is 1/2 mile wide,
but I can rough out a chair seat in less than 15 minutes.  It takes chips like
the big Fritos
