I had a rustle through my old photos and found a few J head photos from some Reliable auctions. I also did a quick skim through my copy of "A Guide to Renovating the Bridgeport Series 1 J Head Milling Machine". There are some comparative photos of bed wear and the comment "...if on the other hand you just see scored bare metal, then excessive wear may be present and it may be better to keep looking".
The photos in the guide suggest high wear.
I've included some photos of the Y ways of some machines in good nick. A far cry from what I observed yesterday.
I reckon I'll walk away .

Hmm I wonder if you can tell much just be looking at ways?
The last picture I like as it looks like there has been wear since the flaking was done.
The 6th picture looks like the flaking might have been done on worn ways to pretty things up.(though maybe not. maybe it just has just a little wear?)
How does one know?

Why did you make that comment then,or was it to try and see who noticed they were different.

Which comment would that be?
Machine A "looks like there has been wear since the flaking was done."
Machine B "looks like the flaking might have been done on worn ways to pretty things up."
I recall now that it even has a name, Flaking rebuild or something like that.
I guess you just need to be sure the gibs a tight and feel how it moves at the extremes of travel.

Sorry the way I read it I thought you were making post and present comments on the flaking as being the same machine.

Sometimes my abuse of the English language gets in the way of me getting my point across

I think it was Forrest or maybe Rich King that coined the phrase "Biax Rebuild"
Machine B "looks like the flaking might have been done on worn ways to pretty things up."

There's something very after factory gone on there.

Phil
Would that be the addition of 2 grease/oilers on the left hand side above the dovetails

G'day John.
I hadn't noticed those until you mentioned it. I'd be thinking they are an addition. I was mostly noticing the flaking / mottling pattern on the knee ways.
Those nipples are just screaming "Pump me full of grease"
Regards Phil.

I doubt it. You certainly won't get ISO 40 because the spindle is too small. ISO 30, maybe. IMO if you buy it, you go with the taper it has. R8 is pretty light duty but so is a B/port really, their strength lies in their versatility not their ability to remove lots of metal fast.
That 1J head isn't a bad milling head, same as mine except mine was made by Adcock & Shipley. Never had any trouble with the pancake motor on mine.
I think it's overpriced for its condition, FWIW. With the amount of wear in the ways it's scrap as far as a precision machine tool goes. Capable of being restored, sure, at a cost in hours. Comes back to the question of whether you're buying a machine to restore or a machine to put to work and what dollar value do you assign to your time?

Well Boys,
I've decided I won't be pining over the Singaporean while I'm visiting the Tool Capital next week. If any local enthusiast wants to try his hand at machine refurbishment, the Bridgeport resides at Abe Schneider's in Dianella.

I'll stick with working small.
