Truly original questions

What is the best steel to use for "Flipping" a folder?

I'm having problems with stick slip on the Y axis on my largest machine. I'm considering changing way lubes (currently Mobil Vectra #2), but I'm wondering if I should go up or down with it? Intuitively it seems like a heavier oil would be a better lubricant, but the ways are really wide (large surface area) and they're really flooded with oil, so I'm wondering if a thinner oil would be better.

If this a true question? We switched from Vactra II to "Condat Waypure 68" over a year ago. The difference in oil is apparent right away. It is much cleaner looking, and has the same viscosity but without the harmful esters, and sulpers that gum up oil systems. This was reccommended to me when we switched to a semi synthetic coolant.

You got to admit, this is a new question for this forum...

Yeah its a real question.

I buy it in 5 gallon buckets about once a year. I started having this problem after I changed to the new bucket. Could be a coincidence...

I think heard they changed it so it wouldn't mix with the newer micro emulsions. And it does separate very nicely. And perhaps at the expense of not working as well?

I ordered a gallon of #4 yesterday and I'll see how it works. After that I'll try some different brands I guess.
 
Nathan, I have heard of this from a few people, But it does not make much sense to me. They say they get different results from a bucket compared to a drum (they say the oil is not the same). I have no proff to back this up though, only hear say so take it for what it's worth. We go through about 4 -5, 55 gal. drums of way oil a year. Since I switched products I have noticed a difference in coolant cleanleness, and less tramp oil in the sumps.
 
"slip stick" Wondering what this term refers to. Does the oil cause uneven movement of the table,(sticking then slipping) does this apply to only CNC work? I can only guess.
Thanks Mark

Stick slip is something you get when the coefficient of static friction is significantly higher than sliding friction. I don't have this trouble with my other machines, but they're smaller. On this particular machine, there is a lot of weight on that axis, and there are large box ways with a lot of surface area between the ways. It causes wind up, so when I'm indicating a fixture and moving in .0001" increments I'll get no motion for a couple tenths, then it breaks free. There is no lost motion, or it would be backlash, which is something different. I'm pretty sure there isn't a mechanical problem, so I'm suspecting the lubricant.
 
Thanks Nathan for taking the time to answer that. Thought it might be something I should be aware of as a newbie to milling, but I'll probably be lucky to work within a few .000

how to on injecting nitrogen into evenheat/paragon furnaces?

Not original. I discussed this with Paul last spring. We figured we could get 100% Nitrogen from the tire shop or welding supply. Easy enough to add a barbed connector to the back of the kiln and just fill it up.
 
zaph1, did you do it? Care to share your results? Just thought id throw it out there see if its being done by any members and how exactly they did it? Im not sure wich paul your refering too?
 
Who really uses words like "higgledy-piggledy" and "kerfuffle" in conversation? :confused:

I have lots of elbow grease and unobtanium. It all comes a dime a dozen, I'm surprised more of you don't have a bunch laying around. ;) :D
 
Why is the flashpoint of canola oil so low on this forum (only)?
