< Is this any easier with plastic parts? Is there any easy way to make < molds? I don't want to do it, just curious (modern appliances < usually depend on a single .5 cm plastic cog which of course tends < to break or wear out after a few months' use) generally plastic is easier to work than metal. depending on the part you can machine it out of a block of similar material. Used to make a lot of parts out of DERLIN, teflon and Nylon Allisn
