Confirm marks on mill table after vise removal - 3 weeks and treated table

[erixgix]

Hey Folks, I took my new vise off a new pristine table after approx being mounted approx 3 weeks. I am seeing lines of darkening. Not sure these are rust as it does not make sense to me based on time, treated surface, and not being particular humid (mid upper 50's RH) and that they are not a color I would expect, just dark. Looking to confirm if these is rust, staining from product, or by product of some other form of oxidation.

Prior to setting it in place, I put a healthy layer of Fluid Film (lanolin based) on the underside of the vise as well as the table. I took the vise off as I need to lift the mill to set its trip tray, and had left it off for a bit over a week, went back today to put it back on and after wiping the table was surprised to see dark marks corresponding to the relieved parts of under the vise and its outline.

The lines correspond to where the heavy deposits of Fluid Film were. The underside of the vise also had the same markings, again where the heavy lines of film where. I dont know if they were there at removal (since I did not wipe them down as I probably should) versus after sitting off for a week. My though is this product is the type that suspends moisture and that possibly too heavy a layer is a bad thing?

The lines do not remove with solvent. Non reactive to rust product like naval jelly. Come off with scotch brite pad.

Thoughts?

It gets lots worse than that! It gets black, and can also form on dovetail slides.

I call it staining. Your mill's not new anymore, get used to it.
Wait until you put your first nick in it.

Makes it easier to indicate your vise back in. Just place it on the lines! Lol

I think the word you are looking for is patina. Patina is a good thing just ask the antique dealers..

Wait...I can get a nick in it?? The horror.

I think your onto something, it also occurs to me when it goes back on the stains go away.


Thanks folks, I was more taken back by how quickly these set up, I didnt expect it for at least a year. I've found a couple mentions of different recommendations to remove those stains, may try before putting it back on to see if a different oil product reacts the same.

Try Boeshield instead of fluid film. I have tried both.

Yeah. I have that, too.

I found that many cutting fluids stain metal when left too long. If I know I won't be able to wipe down everything right away, I use Boelube or WD-40.

Boelube doesn't stain (as far as I can tell) and comes in liquid, paste, and solid forms.

I'm not as familiar with Boeshield. Is that similiar?

 

[rwm]

I think Boeshield is peroleum based while Boelube is not and is biodegradable. I prefer the more toxic and dangerous version.

It's also flammable which is nice.

Check out this video from Fireball Tool regarding rust inhibitors. Most left staining of the metal but a couple of products were standout performers
