We "had" a thread here on work benches, and shots of what everyone was using. Good idea planning your bench, so much to consider.
Will you carve standing or sitting?
Will it include storage for tools, and material?
Will it require a vice or two?
Will it have a place for tools in use?
Will the work surface be fixed or will it tilt?
Will you require drawers under it?
Will you need room for your legs and feet under it?
Can part of it swing out to straddle like a carving horse? Or down like a lap tray?
Can it be bought or will I have to make it? Out of what material?
No end to the ideas....but anything will be better than a card table!
