on 179 we had great success water cutting sprockets out of 1024 high strength aircraft grade aluminum. it took some finish work with a file and a sander but they work extremely well. this past year we bought a plasma cutter. and tried some sprockets. What a mess! the plasma cutter itself is extremely inconsistent and melts allot of material away leaving some tough nasty slag all around any contoured edge. the heat warps plate to the point that whatever you cut was moving while it was being cut so accuracy is not guaranteed. to cut something as small as Usable #25 teeth is nearly impossible with a plasma cutter unless you has a submerged table to dissipate the heat.
