So one of the other projects I wish to accomplish this year (towards spring/summer) is a foot powered grinding wheel.
gives you a vague idea of what I’m going after. The image, btw is from http://autonopedia.org/crafts_and_technology/Wood/Wood_Harvesting_with_Hand_Tools.html which might be of some interest to others.
So the main choice facing me is natural stone, either harvested around me or from a stone yard, or to make a wheel using concrete/abrasive sands, several recipes are online for such things. I haven’t completely decided which yet.
I DO know that whatever wheel I end up with, I’ll place in a trestle base with an enclosed water well, so a bottom portion of the wheel can be held under water, which lubes the work, keeps the stone and tool edge cool, and helps clear the grit. However, a plug will also be incorporated, since leaving a stone underwater will lead to crumbling and softening. If I make the wheel from pourable materials, I can then embed the crank parts, although it’s just a small design change and some serious drilling if I go with a natural stone. The book Homemade Contrivances (http://www.goodreads.com/book/show/1240235.Homemade_Contrivances_and_How_to_Make_Them) has almost exactly what I have in mind on pg. 308. PS, if you don’t have that book, you might want it.
Next step, finding or making the wheel…
