Looks like safflower oil has the highest smoke point, I'll get a quart next time I'm at the gittin place. >has a good table of smoke points; some are over 500 F. :-) > >The point about not using castor oil is a good one. > >I wonder about forming the small hole in the mister by simply squeezing >the brass tubing around a small mandrel like in forged rifle barrels. > I found, when I arrived at the hobby store today, that I didn't have any of the smallest tubing, which is 0.062" in diameter, and a very small passage. So I now have a brass block made up as described, and the mill was able to drill a 1/16" hole that is very snug on that tubing, so I made the inner nozzle projection adjustable, and it is quite well centered in a 5/64ths inch air hole. I also found an air filter whose bowl will hold about 2 oz of oil. I will feed the main air through it, which will pressurize the bowl to match the air pressure (less than 75 psi because of the 1/8" vinyl hose for everything). I also put a teeny needle valve in the oil hose attached to the automatic valve in the bottom of the bowl so I should be able turn it down quite a bit. With the bowl mounted on the mill head, and slightly below the nozzle, just turning off the air should stop it all. Not tested yet as I need to fabricate the filter bowl mounting yet. >I hope you are not seeing rapeseed being sold for human consumption.
