    Default index milling machine

    Thanks for all the info it sure does help a lot.


    The guy got back to me but he could'nt get the model number. But here is what I got it's 2hp,comes with a set of collets 1/4 to3/4 with m/t holder this is a brown & sharp tapper, 9 x 42 table, power feed on X axis and spindle, 220 volts 3 phase with a phase converter.

    Is brown & sharpe tapper bad? I was hoping it was R8 but I don't know these machines to well. Would I be able to get things for the brown & tapper easily?

    Hello Dark Knight,
    Sounds like the Index mill is about the size of a Bridgeport. The accessories are a good deal. The #9 B&S taper is not "bad" just tedious to remove when stuck. They are still available from selected sources but not the Grizzly-Enco big box store sources. Check Kitts Industrial Tools (1-800-521-6579) in Detroit. It was a fun place to shop when I lived in that area 30 years ago.

    Another B&S taper sources is Production Tool Supply in Warren, MI and elsewhere. This is where I got my B&S #9 taper endmill holders for my US Machinetool Cincinatti mill 25 years ago. I got a 1 inch toolholder for big mill shanks.

    Endmill toolholders use a setscrew to lock in the cutter rather than collet squeeze. Mo better especially for the sticky B&S taper. The B&S taper tooling is getting scarcer. Perhaps ebay may be a handier source for these.

    Check all sources before buying any mill to your satisfaction.

    What he said about checking on the B&S taper thing, once you know what's out there campared to what your getting (you might be getting more then enough to work with), I think the price is fair for what your getting.

    No I called the guy to look at it and somebody drove to his house and gave him 1200 dollars without even looking at the machine.

    I think I'm going to get a bridgeport at a industrial surplus store. The parts for them seem very common and they have a good rep. I've been looking around and you can get a 1 hp with power feed for $1200- $1300 or cheaper. I think R8 is the way to go as well.

    I was thinking that 1 hp would be enough power. Have any of you guys with a 1 hp bridgeport ran into issue with not having enough HP? I'm probaly getting to big of a machine but by the time I buy and move a bench model and all the tooling I might as well get a bigger machine.

    Hello Dark Knight,
    Be sure to check the quill taper on any Bridgeport mill you find as some didn't use the popular R-8. B-Ports aren't THAT big (but not a toy either)!!! The dove tail rams as opposed to round kind are the desireable type of B-Port mill. Yes, lots of parts both new and used are available for these machines.

    One HP should be enough power if you have true 3-phase current available. A static converter box will provide only about 2/3 HP for a 1 HP mill motor as it actually is only a starter device so your mill can run on single phase current !!!

    A larger rotory phase converter (RPC) can provide more power ie the mill's full sticker rating when the idler motor has extra HP rating like 33% to 50% more than your mill.

    My K&T Milwaukee 2H horizontal (universal) has an added B-port head on the overarms. I'm restoring that machine for my new little shop. The shop measures just 10 x 15 ft.
