    Okay I started a thread a month or so ago about the price
    of materials. At that time I was in the design stages of
    a DIY audio rack that was a Klone of the Spider Rack ($1600.00 + Dollars)
    from Finite Elemente`.


    I ordered the raw oak from Lowes it's 2"x2" (1.5" x 1.5")
    planed top choice (no knots) 18" long. I cut these down to
    12" long they get sanded gently and 00 steel wooled then
    drilled all the way through the center with a 5/16" hole
    and finaly they get 3 coats of Minwax high gloss wipe on
    Polyurethane.


    The hard part was locating a piece of thick walled Aluminum
    tubing for "cheap" (or free). Everywhere I looked wanted
    minimum orders of 5+ feet (hundreds of dollars) and that's
    where knowing people comes in handy.. Make a phone call to
    a friend who works for Alcoa.. You can't find a better
    place to get Aluminum considering that's what they do! [​IMG]

    So I got a nice piece of 3 1/4" OD x 2 3/8" ID x 18" long
    Aluminum Tubing. The rest of the parts get ordered from
    Reid Tool ( www.reidtool.com ) this is where I will get the
    80/20 Inc. 1515 Lite Aluminum T-Slot material, all thread
    and other needed items ( $172.00 worth). The goal was to
    do this project for under $250.00 total if possible.

    I am currently under that thanks to the freebie chunk of
    Aluminum. The Oak from Lowes plus the Irwin 6" x 5/16"
    Auger plus the Minwax and the 00 Steel Wool came to $113.00.

    If I had to buy the Aluminum from a small supplier plus
    pay to have it machined it's doubtful I could could do the
    project for less than $300 or so dollars (which would still
    be a bargain for a rack of this caliber. This is hardly the
    average MDF and Allthread Flexy Rack.

    Where do I stand?

    I have to get the Aluminum Tube cut down into 1.5" thick
    rings and have 3 5/16" holes drilled at 120 degree seperation
    then they need to be finish bead blasted.

    The beams need drilled yet and I need to figure out how to
    get the radius into them where they will sit against the
    rings.

    And I need to get my order with Reid placed so I can get
    the leg material, fastners and allthread here.

    Here is a picture of my concept render and below it are
    some progress photo's. More to come! and when I am all
    done I will try to have a materials list and assembly guide
    for anyone who wants something more high end than the
    typical Flexy Rack.

    My rack sure looks alot more beefy than the Spider I got
    the idea from [​IMG]

    The nice thing about my design is that there are no holes
    in the legs for vertical adjustment. You are not limited to
    any fixed points it can be moved as little as a thousandths
    of an inch or as much as 4.5 foot!

    This is true, but it's also going to take you some time to make sure each one is level with each other. I'd give up that extra 1/2" for that...

    Looks pretty beefy to me:

    I'd like to see that rack with equipment on it. I've built my share of traditional DIY racks but while that one looks good I don't think I would have a use for it. Is it intended to hold audio gear or is it sturdy enough to support a television or CPU monitor?

    Chris,

    Leveling my shelvs won't be that difficult. Due to the
    design each tier will move as one unit and with 3 legs the
    whole assembly will be easier to level than a 4 leg unit
    to begin with.

    The Spider is beefy but mine is far more beefy than thier
    design. The legs I am using each will support 1500 pounds
    per leg, the beams and center section when secured should
    have no problem holding 250 pounds per tier.

    The Spider is a very nice rack, thus the reason I choose
    to make something similar. But at $1600.00 dollars for the
    5 level rack (and I need 8 levels) that is completely insane
    pricing IMHO.

    HEY Chris, does that guy in the picture know that he's not in the sweet spot! [​IMG]

    Brett, I wonder if your rack will dethrone my current champion, the Le mans rack levitator combo. If so, you can finally enjoy music through an 8.1 earthquake without your CD player skipping. (Oh wait, you don't live in California) [​IMG]

    Anyways, nice work so far. Looks very Sci-fi and modern... Would probably go well next to my keg sized bass traps. I think I'd probably want to make a simple one once I get some home theater equiptment that could go on it. It would be pretty sad to see a nice rack, with a mid-atx PC tower sitting on it.

    Chris,

    $3K for a five tier rack.. HAHAHAHA This whole audio hobby
    is run by a bunch of crack headed designers! As the girl
    would say on Mad TV... Shaaaa, Ya know what? HUH UH....

    Heh

    After I get this rack done and get my XO mods done I may
    have to build a set of your Bass Traps [​IMG]

    Anyone have a source for the pillars that are used in the spider rack? While I'm probably going to get T-slot extrusions from Bosch for my the rack project I'm working on, those are kinda neat looking and I could see using them in a different project.

    www.onlinemetals.com seems to have good prices for most standard metal materials. They custom cut and do small orders, which is something that has been hard to find.

    Oh yea, those are some ugly shoes...
     
  14. hey guys....don't make me bust out the aluminum and hit the machine shop!!! I might have to open a can of "woops....damn. I F'd up another piece of Aluminum" on you all!

    Lol Gomer!


    Travis,

    I haven't found a source for that particular extrusion.
    80/20 Inc. Makes different shapes of the T-Slot material
    though. If you could locate a supplier of Extrusions I am
    sure you could find this material.

    Yea, i'm familiar with both Bosch and 8020, as well as a few other manufacturers. The actual Spider extrusion, I still have yet to see anywhere.

    With your project, how are you planning to mount the arms to the extrusion?

    Travis,

    There will be a 5/16-18 allthread running through the center
    of each beam. Tack Welded on the end of each All Thread will
    be an 80/20 T-Slot Nut. The All Thread rods with attatched
    T-Slot Nut go into the Extrusions and then through the beams.

    Then through the center rings and finaly it all tightens
    down at the center with nuts or thumb screws (whichever fits
    best).

    Makes sense. Was wondering where the allthread was gonna be used. Look forward to seeing the finished product
     
  20. I'm just going to have to machine those centers and charge you people up the arse for them [​IMG]
