As my Father used to say when we were causing trouble and Mom wanted him to intervene, "fight nice"
I read a lot of these posts and and I am amazed at the tensions and animosity that result.
I am actually reading this post to learn about Rays problem as I believe him to be a pretty sharp guy when it comes to Mach3 and its use. I didn't come here to read these posts to listen to people get all upset about what may or may not have been someones meaning.
AS far as clicks are concerned the only one I belong to is the DSPMC users which is by far in the minority. I forgot the other "Click" is the Mach3 users click in which if you are a user of Mach3 or even know about Mach3 your are welcomed in.
Back to the topic at hand. I can't imagine the use of kero on a daily basis. The smell makes me sick and I would be very concerned about the fire hazard. I do remember reading somewhere that it works well for drilling cast iron but I could be mistaken.
I also can recommend against the extensive use of WD40 in a mist lubricator. I had read that it works well for aluminum and it did a good job of keeping the cutter from clogging up but I had breathing troubles for a few days after a long machining session.
I have gone to water mixed coolant and I am very very happy with the result. Mu only real concern is the evaporation and carry off of the coolant. To minimize the carry off I have taken to washing the parts in clean water and then using this water to mix new coolant with. Since this water already has a percentage of coolant in it from washing the finished parts, I reduce the carry off some what.
So far I have not had any smell from the sump and the machine will sit for days and sometimes weeks without odor build up. I have even converted my bandsaw too use this as I like the all in one type solutions.
While I am sure that it is not the perfect coolant for every job, it has so far stood me in good stead.
