Well, I’ll be blowed, now I can understand perfectly why so many people prefer the dumb head shaving horse. I’d been getting a bit irritated at the way wet deer legs (OK hazel branches) were inclined to rotate while working a tenon up with a rounder plane so I thought I’d take the plunge and convert my donkey into a horse. Here’s the old fellow:
This is an old photo, and I think all parts but the front leg and the bottom footrest in the frame were replaced by the time I converted it.
Here’s the new un:
I used the legs and bed from the old one. The treadle is a little high on the dummy, but I was following plans. I’d really like to add in about 6 inches to the middle of the lever/treadle, my Sunday apprentice Rich may find this one a bit cramped 😦
Anyway, I measured up the comparative leverages of the two horses and the old English frame version gives about 1:1 advantage (i.e. none) while the dumbhead gives about 4:1 mechanical advantage. Now why would anyone use the frame one with such poor pressure? Bit like using an axe without a handle! I feel longer legs coming for the stock knife ‘bench’ ( AKA ‘stock’ – that’s presumably how the knife got its name, the favourite first task for an apprentice joiner was making his sawing stock). Longer legs would mean less bending when using the knife. Fortunately the stock knife I bought as a clogger’s knife seems to be a peg maker’s knife as the handle is hardly swept compared to a clogger’s which is severely bowed, and increases the back bending effect. Poor old bones.
So I also managed today finally to ‘install’ the new extension stove-pipe that David gave me, well I say install, rammed it into the old pipe and wired it to a shelter member at the top to keep it away from the tarp:
Much healthier having that smoak outside the shelter. You can see the 75 foot ‘leg’ of my pole lathe in the picture above. It’s a felled beech tree that’s been down about three years now and is doing its job playing host to various fauna and flora and these (which seem to be neither):
These are on the stump:
And amazingly, there is a little regrowth from the stump too which I missed when it was in leaf:
I spy the buds ready for Spring
