    Default Ebay Bridgeport

    Saw this on ebay (not affiliated in any way BTW). Looks like a great bit of gear. If only I had the room, cash and an idea of how to use it.

    Nice machine if you could get it for that price .
    Too far away for me though , no room for it either.

    The owner has done a damn nice paint job. Hopefully the scrapping is as professional as quoted as otherwise it is just a half way done.

    That's my dream machine!
    Great size for my workshop, and that model does everything that I could want. I love the fact that the head nods on these machines.
    Too bad I just spent my excess funds on a new troop carrier.
    I hope it goes to a good home.
    If everything he says in the ad is true, then I would think it would be a very good buy for around $4500 to $5k. As with all of these things, I shouldn't think he should expect to get back the $6k he says he has put into it. That's just the way it goes IMO.

    I have exchanged emails with the seller and I believe the way scraping has ben done very well, but I am going to inspect it Friday. One thing though, to avoid disappointment, there is a small paint chip in one of the photos. Something like that can really affect buyer satisfaction-I'd hate to be outbid by someone who will just end up being bitterly disappointed with the frustration of finding a paint match and finding the time to fix it.
    The chip might be a scratch on my monitor, but better safe than sorry.

    On a serious note, I too have space and expense issues. I do expect it to fetch a very good price, but know that the market undervalues the expense and effort of a fresh rebuild.

    Thanks Chris...I'm going to bring along my measuring tools to do a quick survey. I'll be able to check the table's flatness easily enough, the other checks I guess will depend on if the machine is in tram when I see it.

    I am scraping my worn out Hercus right now and admire anyone who can scrape dovetail sliding ways to any accuracy let alone machine tool standards. I guess that the Hercus will take me 30 hours or so to scrape in, and another hundred or so on the rest of the machine. I'm trying to ignore the economics of that by only doing three hours/week so that it doesn't seem quite so stupid.

    Greg the only way to tell if the machne is eney good is to take a cut over a ditence with it. But you have to asc yourself how accurite do you need it to be. Half a thow is a lot les than 5 thow what do you intend to do with the machine if you need to dorow a clamping kit and a cutter you know where i live

    Hi,

    Does anyone from Melbourne know of an excellent industrial removalist? What do you think the cost would be for a 20 km trip?

    Cheers

    Haha. Don't know of any myself, but rock on, mate. That machine looks like a bloody ripper. Spewin' I don't have $3,000 in the bank. (Well, I do, but that's the untouchable ZX-10R fund. Will resort to taking all my anger out on the Taiwanese bit of rubbish at work in the mean time, I guess.)
    'What the mind of man can conceive, the hand of a toolmaker can achieve.'
    Owning a GPX250 and wanting a ZX10 is the single worst experience possible. -Aside from riding a BMW, I guess.

    My pesky employer required my services today so I couldn't go and inspect it. The seller said that he had a few people around yesterday to view the machine, and I see that four bidders have it up to $4,100 now.

    I hope for the seller's sake that he covers his costs...this looks like a great machine-I've seen crap ones go for more than 3K, and there's a huge amount of time/money in restoring one. You don't see restored machine usually, but you do see a lot of overpriced, worn out scrap.

    Without a decent inspection you will never know if it is as good as claimed or a pretty paint job....speaking of which I must give mine a spruce up one day

    Hi all,

    I'm a very infrequent reader of this excellent site's forums, and just popped in to discover that it's my Bridgeport mill that's being discussed here!

    Wow. I always wanted to be famous, and even though this thread is about as close to my childhood dream of being a rockstar as I'm likely to get it's still pretty satisfying

    I just wanted to say that the machine is indeed every bit as good as I claim it to be in the add, and just to satisfy any fears about the scraping it most certainly was done professionally by a retired toolmaker with over 45 years of machine tool rebuilding experience.

    Also, Brigeports (or any other milling machine that I know of) most certainly do not have an intentional bow in the table or bias of the knee as part of their design to compensate for weight, as doing so would make accurate milling of long jobs impossible. All of the ways on a Bridgeport were hand scraped originally at the factory to be perfectly flat and true (they were all hand finished and never ground), and that's the only way you can gaurantee accurate milling.

    The only part of a Bridgeport that had any bias at all was a one thousandth of an inch bias on the table front to rear (the front of the table was .001" higher than the rear) over it's length to accomodate for vices almost always being mounted off centre towards the front. This process was apparently dropped in the late 1950's or so as it was found to be largely unneccessary.

    I've seen plenty of milling machines with a ten thou bow in the table (and then some), but you can rest assured it was never there when the machine originally left the factory and only came about after many years of abuse

    I appreciate the positive comments, and like some of you I hope the machine goes to a good home. I've put a hell of a lot of time & money into it, and even contemplated which one I'd really prefer to keep: The machine or the wife

    Regards,
    Darren.
