I recently had a commission for a pretty unique plane - a Classic Smoother in African Blackwood. But half size! No big deal you may think, but it was quite a challenge. I have made a good selection of specialised tools for making planes but most were too big to use on this plane. So I ended up making yet more tools. And I often mutter to myself when working down in the throat of a plane how little space there is to work - with this plane there was even less!
But she came out well and the customer was very pleased - it now lives with in his collection of special planes.
