I have a welder, grinding wheel, milling machine and access to a lathe and cnc machine. Fabrication isn't the issue, time is. This is a hobby for me as opposed to a must have or business related going concern, I could buy a purpose built machine or have the fun of building the ps3 into something different, just because I can.
As to those who asked me why bother? There are a number of reasons, besides the clamp mechanism the ps3 machine is actually well built and the way it is built means I can make many adaptations to it. And it has one huge advantage over all of the other automatic sharpeners in the lower to mid end of the cost market - minimum electronics. AND - the sharpening wheel isn't controlled by the machine. Besides Prosharp supplied wheels, I have also sourced a range of traditional stone wheels and when the right stone is used for the type of blade in the machine I get a sharpen as good as many hand sharpens I have had. I still have to remove the sharpening wheel to dress it (pita atm) but I'm going to add the pencil into the case next month and make the electronic adjustments I need so I can spin the wheel to dress it but the wheel carriage doesn't move. I'm also thinking of removing the existing front of the case and replacing it with a door so I can get quick and open access to the inserted blade and sharpening wheel and adjustments. Then I can add polishing passes and, with some other stone wheels I have coming, play around with wet and oil sharpens.
