Well, it's 1 pound which is equal to about $476.84 at todays exchange rate http://bbs.homeshopmachinist.net//eek.gif Other than that I'd jump on it...

Well, he did provide good pictures. Can't really say he is pulling the wool over anyone's eyes.

For one dollar it might be worth it.

Not with something approaching 8 pounds for shippping, whatever that works out in money.

Surface rust and what looks to my eye like rat pee... don't ask me how I know what rat pee on tool steel looks like. http://bbs.homeshopmachinist.net//mad.gif

deepest surface rust I ever did see
Rat pee sounds interesting, do we have a story there?

How could you clean that rust off without affecting the cutting edges? I have some tools from an auction that are in the same condition.

He should have engraved "Whitestar lines"on the side and listed them in collectibles http://bbs.homeshopmachinist.net//biggrin.gif

>> Rat pee sounds interesting

Great, now we've got a guy on here who thinks rat pee is interesting... http://bbs.homeshopmachinist.net//rolleyes.gif

You remember that Homier 7x12 that I'm (slowly) converting to CNC? Well, it was in my garage, with all it's tooling, having been disassembled to take measurements and design the conversion kit... Well, after a while, (remember, that project is only one of several I am working on, and it's not the most important one, either) somebody in my household - who, for the purposes of domestic tranquility, will remain nameless - started to pile stuff on top of the tooling, obscuring what was going on underneath (this in a space that is really too small for the amount of stuff in it).

About the same time, it was starting to get cold outside, with the predictable thoughts of nice warm nests in-between sheets of cardboard beginning to be formed the little brains of those wonderful little creatures, commonly known as field rats. And which garage did they choose for their cozy little burrow amongst the sandpaper boxes and spackle containers? Why, mine of course! But did they just choose a spot off in the corner somewhere, where they would be an annoyance, but not a real hazard? Nooo, they went straight for the spot where my lathe was, and set up camp right on top of the tooling! And, being rats, they didn't have the common courtesy to relieve themselves elsewhere - nooo, they did it right on top of the tooling! Leaving me to discover, a month or so later, when I had finally gotten around to going back over there and cleaning the improperly placed stuff up, quite the mess. At first I thought that my rust-prevention measures had failed (I had oiled everything throughly, but perhaps not throughly enough? or was the oil hydroscopic?), but on closer examination, the "rust" patches were splotchy, with some areas showing no damage at all, and the Formica surface on which the tooling was resting was rusted also! http://bbs.homeshopmachinist.net//eek.gif

Now, knowing a little bit about the metalurgy of Formica, I realised that it didn't rust easily- and that the small bits of brown stuff and occasional short, brown bits of hair scattered about the area were probbably connected to the sudden corrosion problem that my work surface and tooling had developed.

Fast forwarding several months, the rats have left, (evection notices having been served by Sherrif Purr, a.k.a. Jon the Cat, a.k.a. Short, Orange, and Furry), the tooling has been cleaned off (first with a disposable vac located outside - well, what else do you call a $29 shop vac that went promptly in the dumpster? - and then with generous quantities of Clorox Clean-Up and a wire brush) and now I check the condition of the tooling much more often.

P.s. - Did I mention that I hate rats? http://bbs.homeshopmachinist.net//mad.gif

you hadent mentioned that you hate rats but I guessed it any way another thing that is hard on tooling or any metal serface is sheetrock mud for those of us who are working on our homes

been "dumpster divin'"again,alistair? http://bbs.homeshopmachinist.net//biggrin.gif http://bbs.homeshopmachinist.net//biggrin.gif.he'd do better advertising it as "rust with the occasional bit of tool steel attached http://bbs.homeshopmachinist.net//biggrin.gif

Ahh, let me see, If I get a rusty Lathe, then some rusty stock, all I'd need is some rusty tooling! My God! Nothing is imposible!

I used to think sandblasting was the only truly effective rust removal technique until I used a 30-60 minute soak in Hydrochloric acid for taking off that kind of rust off steel before. However, it wasn't on a cutting tool, so I don't know how it would affect the cutting edge. Afterwards, I use metal polish and follow up with Boeshield T-9 (a rust inhibitor spray not available locally -- ordered mine from
http://www.homeshopsupply.com) Granted, the kind of rust in that auction would still probably leave a lot of pitting.

Hydrochloric acid comes in the form of "Muriatic acid" that is often used to get the correct pH balance in swimming pools -- should be available at most hardware stores -- I get mine at Home Depot for about $4.00/2 Gallons -- Nasty stuff, but works great -- don't let the fumes on stuff you're not de-rusting.

disclaimer: Use baking soda or lime to neutralize any acid before disposal.

You have to understand. For the UK that IS surface rust. If it was more than surface rust, all you would have is just powder.

Boy did you make out! http://bbs.homeshopmachinist.net//biggrin.gif Near as I can tell by the picture, the rust is only on the outside!

Nice to see that you're still with us, laddie!Just as dour as ever- I'm delighted to note.

Who has been sneaking photographs of my workshop?
