    Default Low-cost Indexing?

    Anyone (VZ?) seen these? Wondering where these are on the gimmick/useful scale?

    I'd be interested in a cheap dividing head as well.

    I have been looking at this indexer. It can also be fitted with a 6" 3-jaw chuck. I realize you get what you pay for, but will it be alright for hobby work? HORIZONTAL / VERTICAL 5C COLLET INDEX WITH TAIL STOCK - eBay (item 350148793672 end time May-03-09 22:38:07 PDT)

    Hello Guys,
    Those little indexers are sufficient for small shop and hobby work. They are intended to position a piece of work systematically for a mill or drillpress.

    Generally they do not have a worm gear drive that will allow milling a semi-circle type cut. Yes, you can mill flash hiders etc using one plus the tail stock support. The work is rotated then locked down for milling etc.

    These are all Chinese made items which allows a very modest price for a new piece of equipment. They typically cost less than a rotary table which does have a worm-drive gearing.

    Many rotary tables have provision for a collet attachment and/or a chuck. Some will also do horizontal and vertical positioning.

    So the bottom line is what sort of work do you want to be able to do ??

    The 1 degree increment is a little big if you want to some stuff but for the price you will be amazed at what you can do. GO FOR it. I like the first two.

    A question - how does one utilize the indexer that uses collets? In other words, how do you mount your work using a collet? I've never considered how to mount a headstock, but would you actually mount that to it in a way similar to how a live center is mounted in the tailstock? VZ, I don't really get what kind of mounting tool you're using in the pics you shared here:

    I found that spin indexer elsewhere for the same price:

    JTS Machinery & Supply Co.

    Now if I can figure out how to mount my (lathe) face plate I'll be all set!



    I should mention the HF tables as well:

    FYI, I just got one of the 1 degree incremental spin indexers for $28 on eBay! I purchased a 1" collet as well - already have the smaller ones! With shipping it will be $40 so I figure compared to the other ones it is free shipping.

    Still trying to figure how that drawbar thingy would be mounted. If they don't make one, I will make some sort of adapter for my lathe face plate to mount up. A 1" bolt with a bushing or screw stop of some sort will probably do the trick.

    I don't think it is as fancy as VZ's shop pickup find, but I think it will get me started! VZ, looking at the prices of older used indexers, you got a HECK OF A DEAL with that one you have!

    We have that exact one at work. It works pretty well.

    Hello hc,
    The drawbar thingie is actually a tube that screws onto the OD threads of the 5C collets and pulls the collets in to tighten the work. The drawbar tube has a knurled shoulder typically at the back end (by the spindex crank).

    The drawbar tubes are hollow so long work with a diameter up to about 1 1/8th inch for the 5C collets can pass through.

    5C collets can be had for square or hex bar stock too. They also make 5C expanding mandrels to attach work via a bore.

    Sounds like I can make one of these "drawbar" mounting bars on the lathe. Shouldn't be too hard I guess...


    Trying to figure out alternative ways to mount the work and I have a few questions.



    I know I'll find out when it arrives, but do my existing collets work with the indexer? The ones I have are threaded only on the inside for use in my mill with its drawbar. Or do I need to get some externally-threaded collets? That discount tools guy on ebay sells them for $3.50 each but I hate to be stuck waiting on new tools to arrive so I'll plan to buy a set if I do need some more.


    I don't know if every time I use it I will have a hollow work piece? If I need to work on a solid of some sort, I'm thinking I will probably need a "flat" base plate adapter (thinking a bolt cut off above the threads and a mounting plate of some sort) so that my lathe faceplace can be mounted. That will use the conventional T-blocks and mounting shims like you use on a milling machine without the vise. Should let me get some odd shapes mounted up without needing to go inside them. I'm thinking about that worm "gear" for the helix magazine



    You know VZ mentioned his indexer doesn't use a 5C collet so I wonder if it uses the other collect design forget the name - 2M or 3M?? My tailstock uses that one and it is thinner. It begs the question, is there a 3- or 4-jaw chuck that can be mounted in a 5C flange? I think my heads mount to a plate which is bolted directly to a drive shaft, so I don't know if they make an adapter or some sort...? I'll need to look in the tools catalogs to be sure.
