If you just want to try out the 'pipe' edge method, go to a plumbing supply shop and buy a lenght of black ABS pipe. You can use normal white PVC stuff, but it tends to crack real easy, especially cold. I use a 2" pipe, but it really depends on how far up from your replaceable cutting edge the bolts are that hold it on. The bolts that stick out the back is what helps to keep the pipe on. After getting the right size pipe, CAREFULLY slit the pipe on your table saw. Set the fence on the saw so the blade is about in the middle of the pipe, lower the blade down to cut only one side of the pipe, wear glasses, watch fingers, etc. After you get the pipe slit, cut it to the lenght of your blade. Raise the blade up off the floor. Then spread one end of the slit open with a big screwdriver [ or whatever ] and push it onto the end on the blade to start it. The pipe should be sized so it will fit over the ends of the bolt ends [ the ones with the nuts and lockwashers ], again, this is what holds it in place on most blades. Push the slit pipe on as far as you can, which probably won't be far, then drive it all the way onto the blade with a big dead blow hammer. [ You know, the 42oz orange one that you allways use. ] The ABS is not indestructable, but will last quite a while if you don't smash it into stuff. I have never tried it, but I would like to try some big industrial rubber hose some winter. That might last longer.
