    You call such people "rare".
    So you'd spend $200 to avoid buying a $6.00 piece...

    uh, no. follow along- i asked tim why anyone would farm such a job
    out to a machine shop; the quote he showed for 200 and 400 pieces as a
    ~$2k/~$4k job. we don't know what sort of order he ended up putting
    in, but my comment, in context (tough for you, i know), is clearly not
    to avoid a $6 job. if it was for a single $6 piece, the context
    obviously wouldn't be to ask why you'd farm it out to a machine shop
    (because, in context, you wouldn't- you'd buy it on ebay), eh? sheesh
    alan.

    Machines shops are where one goes to get 200 pieces of a metal piece
    made.

    no, for one disk, i'd buy it for $6- you'd probably have a hard time
    finding raw stock that fits your need for less than that, and if you
    didn't have the tools, furgetaboutit..

    for 200 disks with a threaded hole, i'd make it myself for something
    so trivial, even if i had to go buy the tools. that's where you'd
    come out way ahead.

    but what do you imagine you'd use a lathe for to make this part (you
    apparently think you'd use a drill to cut off a disk, and then a lathe
    to...? what surfaces do you think you're finishing on the lathe, and
    how?), and why would you use multiple taps- really, why? :p maybe
    that's why YOU'D use a machine shop... :D

    Right. You'd buy it from the outfit that had it made...

    ....in a machine shop.
    You think you can buy a decent drill press and metal saw (yeah, metal
    saw; you're not going to get a uniform disk by mounting a cutoff wheel
    in an angle grinder, you know) and taps (putting aside the lathe) for
    $200?

    LOL
    So after you've used the "cutoff wheel" you mentioned to cut off the
    disk from the round stock, you'd do what to get the faces and edges
    smooth?

    If I were trying to make them (and I had the proper tools), I'd start
    with round stock, cut it to a little bit larger than finished thickness,
    use a lathe to true up the faces and (since its already mounted) use a
    drill bit in the tailstock to make the centre hole. Then tap.

    you absolutely can get a chop saw, tap, and a drill press good enough
    for a project like this. and while you CAN put a cut off wheel in a
    angle grinder, i certainly wouldn't (i'd use a chop saw). that you
    would go to an angle grinder speaks volumes about your experience in
    these matters. :D
    i ain't using a lathe, that's for sure. and "cutoff wheel" doesn't
    need to be in quotes- it's a real thing. to get the face smooth, i'd
    keep it simple- thread a rod into the hole i just tapped for easy
    handling and use a sanding disk!
    wow, i guess if you wanted to do a lot more setup and a lot more work
    than necessary, you could do it a really dumb way like that. ;D

    Prove it.

    Prove you can get a decent drill press, chop saw, and tap for $200...
    I know it's a real thing. It's just an inappropriate tool for creating
    anything other than hack job.
    We'll just write this up as something else you don't really understand.

    Can you cobble up something with a chop saw, hand drill, sandpaper and a
    tap. Yup.

    Could create something that people would want to *buy*?

    for a one off, i'd actually go way cheaper. i'd go to harbor freight
    and get these:
    http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=38119
    http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=44829

    there are a LOT of good options in the $100 range for chop saws and
    small drill presses.
    http://www.sears.com/shc/s/p_10153_12605_00921817000P?keyword=drill+press
    http://www.homedepot.com/h_d1/N-5yc...splay?langId=-1&storeId=10051&catalogId=10053

    i'd *personally* go used, and find something on craigslist though. a
    whole lot of seriously high quality tools for very good prices these
    days.

    for a tap, $6.
    http://www.sears.com/shc/s/p_10153_12605_00952847000P

    you still haven't explained why you initially thought you needed
    multiple tapS. :p
    but you brought up a *angle grinder*?! what do you think is the
    *appropriate* tool one would use for cutting off disks from round
    stock?
    this is like the discussion we had on box sections, where you really
    thought that a box section needed to be fully enclosed- you thought
    you were right through and through while making a total fool of
    yourself. :p
    go take a look at the pictures from tim's action- pay extra attention
    to the edges of the disks. you really think that was something that
    was precision machined, and not something you could do w/ a drill
    press, chop saw, and some light sanding?

    Let me jump in here. I work many hours during the day and most weekends, and
    I bill by the hour and most of it is on a tight deadline; thus, I can't screw
    around with buying the equipment and raw material, then making the darned
    thing, for 200 of an under-six-dollar item. (I won't say how much I ended up
    paying per piece, but it was under $6.) The money I'd lose in my regular
    work would dwarf the money I "saved" in doing myself.

    Wow. You've shown you can buy crap to make crap.

    Rule #1 about tools: if you really need it, then buy it.

    Rule #2: don't buy crap.
    With no warranties and uncertain reliability.
    I never said anything like that.

    I know that to make items in bulk, you go to people who are good at it.

    none of those tools are crap. they have limitations, like all tools,
    but that doesn't make them crap.
    caveat emptor of course- as i said, that's what i'd personally do.
    based on the statements you've made, i'd not recommend you do
    that. ;D

    still no explanation? :D

    well, why did you bring up an angle grinder, and what would you use
    alan?
    you absolutely did.

    well then, something else you apparently don't know- most machine
    shops aren't really in the business of making parts in bulk. ;D most
    of them generally do everything by hand, so by definition do one offs
    or limited runs. :p

    nope. i've tapped a replacement for something much more complex than
    the part in question w/ a similar hf press with no issues. i build a
    replacement for one of these:
    http://www.vortexracing.com/index.p...srctype=detail&refno=19381&category=Rear Sets

    a disc with a threaded hole obviously doesn't need anything resembling
    the same precision, eh?

    if you're going to be tapping a lot of stuff. i've never bought them
    in sets (both that i have). :p


    no, really, how about an answer?

    the context clearly showed that you thought a box section needed to be
    enclosed (i.e. boxed in).

    It needs to be a box *section* in the appropriate directions for the
    loads it must resist.
