Ok then what about a wooden worm gear for your first grinder (with the same limitations other wooden parts have).Yes.
It just feels odd upgrading your worm gear that's made from steel to a somehow more efficient wooden gearbox (lets you meet torque requirements whilst having a ideal speed) as soon as you get enough lube to be able to run it without it failing. Unless it's expected that I skip wood/stone gearboxes altogether? I mean I could, if I am making enough HSLA to make a worm gear why not just skip wood and stone. Maybe there's a use for them I have missed.
