Thread: Unknown Tool Steel

Hi Fred, Joe,

I got talking to one of the guy's who was there helping with the cleanout, in the later days of the factory, long after the business proper had ceased operation, the guy's who owned the place used to wander in and a few of their mates would turn up and they would hang around talking, no doubt reminiscing about old times, and every so often they would do some little machining job or whatever, but I can understand why they were reluctant to sell off the machinery and close completely. They had spent their entire lives working in that factory, probably knew every machine backwards and nook and cranny, only time they ever took off was a few weeks at christmas time, and even then probably couldn't wait to get back to the place.

I would have killed them to have to sell it, so it just slowly deteriorated.. seems strange, but I understand completely why would have hung on so long.

Personally, I'd much prefer to hang out in a machine shop, than a nursing home any day.. In it's hey day it would have been a magic place.

The next stage of clearing the site will be the demolition, but... wait for it... it's already been declared a listed heritage site... they might have problems getting a demolition permit...

Regards
Ray

I have seen BMS (1020) described as Custard colour, but the stuff I have bought from the local steel merchant is a definite Yellow.

You're right Ray, 70c/kg for any steel is a bargain, what sizes did you get?


Edit:

Did some further searching on the Interlloy site and there are actually 2 TWO 4140 grades listed!

The first is 4140 High Tensile Steel, which is BLUE

The second is 4140 Chrome Plated Bar, which is what I have here, and is GREEN.

Some suppliers stamp numbers/letters etc but colour coding is the easiest as long as noboby cuts of both ends

Well, really it should be nothing, my shed space is getting less and less... But you know the deal....seeing old machinery that might be in OK condition for sale like that...

I am probably more tempted by the Norton grinder then the Kao Ming..

I think the most useful thing about that chart for Aussie readers is the warning at the top. I can't see even one colour on that chart that coincides with what is typically used for identification here in Australia.

Richard,
would you like me to ask a price? Sorry, that might be too cruel....
They marked the big vertical mill "$5000"..... I can't recall a price marked on the grinders. You Ray?
Joe

They are dreaming @ $5000 for the Milwakee mill...

Hi Joe, RC,

Don't remember seeing a price on the grinders, but then again I didn't look....

$5000, yep, tell him he's dreaming... but, it has to go somewhere soon... maybe a side trip to Bendigo, with a truck, on the way back to Rocky in a few weeks time...

Regards
Ray
