Veggie oil molecules are many times larger than mineral oil. The ultra thin film needed to properly lubricate the blade is just not there with it.

I'm seeing some pretty intense saw marks- if your saw is outta wack, that may heat your oil to a higher temp. due to increased friction, which in turn will skew your test results.

It looks like the kind of saw chatter you get when a blade is either dull or has a wedge shaped kerf and is having trouble getting through the rock. From the arc of the scratches it may be a 10 or 12 inch saw? If it's a trim/slab style saw cuts like that just happen, not much can be done about it. If it's an enclosed saw then it could be lots of things and is probably fixable.

Thanks guy's, can't get nuthin past you fellas. I just put a brand new blade on the old st-10 it was packaged well, but came out of the box tweaked, needless to say I was not a happy camper. I made an attempt at straightening the thing out, but obviously I missed the mark. The blade is a cheap one from world diamond source. I have never ordered anything from them before and from what I received I would be hesitant to order from them again. I'll try straightening the thing out again and see what happens, fortunately I still have some so so rock that I can test it on. Have any of you guys ever had experience with world diamond? Robert.
