Got the shave horse virtually finished.
Here's a couple of pics (I'm using an imaginary spokeshave... very good tool the imaginary spokeshave, never fails).
The clamp bar will have a soft wood block fitting loosely on it to stop it marking the work piece, maybe with some rubber sheet or leather on it.
The bar is a loose fit so that it can be pulled out easilly. I'll probably have it on a chain or string so that it doesn't get lost (same goes for the legs, which just pull out from underneath).
It will doubtless need some adjustments, I can see that when used out doors the pedal is a bit close to the ground and my foot is acting on the top edge so I may take some off the bottom edge.
I haven't tried it out properly yet, it's a bit cold still, but hopefully by next weekend, I'll have it fine tuned and the weather will be a bit kinder.
The foot operated lever is made up of plywood which is glued and nailed into a sort of box section for rigidity. The main pivot is 12mm steel bar and the smaller clamp bar is 8mm.
Other than two lengths of 4x2" it's just stuff that I had in the garage.
For anyone interested in the dimensions and construction, there are more pictures of the shave horse in it's finished state with a tape measuer for reference here:-
