Probably should have water carrying slots cut in the rim. Would probably have to be made. However, before I start, I am going shopping in the housewares department to see if I can find a bread pan or some such long enough this 10" shaft can be laid in it, and then covered with distilled water. Much easier than trying to seal both ends of a medicine bottle. That should be enough water to do it in one pass.
That water I have several gallons of for the moisturizer bubbler my ladies oxygen generator runs the gas thru on its way to her. As long as its propped not to roll with the tables motions, it should just work and I could just step and repeat for both keys. Thats 1566 steel, I wonder how far in I'd have to EDM, before I could switch to a regular carbide bit under power to finish the job precisely. IOW, how deep does the 60C case hardening go? Carbide was mentioned, I might even see how long this now dull tool would work. Running backwards so the spiral is carrying fresh water down to the fire on the bottom face? Lots of things to try. :) But first find a pan. And have the pharmacy get refill auth for the metroprolol, the heart pill. Thats what they put me on after the pacemaker install. That and rat poison for blood thinner. They said I could stop it, but I'm not bleeding worth a toot /with/ it when I nick a hand, so stopping it could easily lead to another pulmonary embolism. Thats a hell of a way to die, been there, done that, I am one of the less than 2% that survived the first one.
