Suspending hard drive w/ Stretch Magic (picture)

Splinter · Post by **Splinter** » Mon May 02, 2005 7:05 pm

I just did a brief test.

A single strand of 1.8mm SM, looped around a 15lbs barbell was supported for about 2 minutes with no sign of breakage. (I didnt test for longer because I got bored)

So I'm pretty damn sure 4 strands could support 2 harddrives indefinately.

Welcome to SPCR What's a cubit?!!

FWIW, I know the reference...this was on the first Bill Cosby LP that I heard when I was a kid!

Oh yes indeed wim, what a shameless crime to welcome a member so late! Where would we end up without your fundamental remarks!

Heh sorry for being a bit off-topic but I found this quite funny =)

I googled for stretch magic on Danish websites and found http://www.lingerieshop.dk/38/41 which sells some "Magic Penis Ring-Stretch" hehe... Dunno how suitable it would be for anti-vibration. Gotta love google =)

Well that wasn't very nice.... I thought wim was just saying the welcome came almost a year too late.

The danger of "bumped" threads....

whoops i just meant to make a funny, not trying to be a smartarse. maybe my humour is too dry. ok, Bruce, i edited my message..hopefully it is more palatable now

i doubt cubit left in a huff on 19 Aug 2004 because (s)he didn't get a big colourful welcome message. fwiw i never got one either *voice crackles*..excuse me..i have something in my eye..

FINALLY...a good looking suspension system. Thanks for the pic !!!

I was able to source some 1mm Stretch Magic here in New Zealand, but am asking around for the apparently illusive 1.8mm stuff.

I was thinking, what about atttaching some heat sinks to the areas on the side of the HDD, eg as to not interfere with the Stretch Magic, but provide cooling. I have an old coolerMaster CPU heatsink that is about to meet my hacksaw.

As per my crap diagram below...

Just a thought, i will try it when my stretch magic arrives, and post pics.

I like the look of this suspension method !

Does anyone know a source for 1.8mm Stretch Magic in New Zealand ?

Wherever you get plumbing supplys you can get copper straps user to mount copper pipe. Use the srew holes in the drives sides to attach a strip,about 3/4" wide,to each side of the drive as a heatsink. Drives conduct a lot of their heat through the sides. Then just do the whole thing in the elastic

You could use one of the 2 fan aluminum drive cooler that bolts to the bottom of the hard drive. I think Vantec is the usual brand you'll see. Take off the fans and use the rest as a passive heatsink.

Would anyone suggest whether fitting small rubber grommets into the drilled holes in your drive bays would be a good idea? Grommets with a central diameter of, say, 2mm, for the StretchMagic to fit through?

I am about to perform this drive-suspension modification myself, and would not wish for the StretchMagic to become snagged or damaged by the sharp edges of the small holes which I drill through the metal sides of my 3.5" drive bays. What do you think?

Pipps you amaze me with every post you make, but you didn't need to bump up an old thread

Grommets are a fine idea for your project, I don't understand why it would not be fine.

Thank you LodeHacker! I read your system build thread earlier, and you have a fine system in the making. Practically identical to my own!

Hope you don't mind me contributing to this thread. This topic is the forum's definitive compendium of drive-suspension wisdom! If rubber grommets turn out to be the way forward - it would seem right for all relevant StretchMagic and grommet related knowledge to be found in the same index!

Nice, maybe you can help me out? Any recommendations are welcome there

On topic, according to what people say here, Stretch Magic is strong and suitable for HDD suspension. You seem to be enticed to try out modding your case to allow HDD suspension, correct? If so then taking care that the Stretch Magic won't touch sharp edges is a step forward and rubber grommets seem to be perfect for this.

Before starting out though, you might want to look at different suspension techniques. I'm talking about something like this http://www.silentpcreview.com/article109-page1.html

Have fun with your project & all the best,

What I did for that problem was to drill the holes, then take the pointed dremel grinding stones and smooth the holes on both sides...then run finger over them all. When I don't bleed anymore, I know it's all good!

Isn't that a bit too hardcore
