Need help designing a shroud

Stiffler · 01-25-2004, 12:33 AM

I need some help designing a shroud for my rad and fans. I have two 120mm fans, and my rad dimensions are:

7.625"
5.75"
2"

Dang, you replied too late. I'm too drunk to understand a word of that. ROFL. I'll check that out in the morning

man?? what's so hard about making a shroud?
You need a guide or help for that?
Just be creative man!

what is that? a bandaid? you shoulda used flintstones for that.

all you need is some creativity, if that. just make a fake shroud out of cardboard paper and assemble it like a box or something thats cut in half. then go out to homedepot get some sheetmetal and start cutting w/ tin snips. thats what i did and im pretty happy w/ my results. sorry no pic tho, but its decent looking.

Dieter@be · 01-25-2004, 01:09 PM

well yeah it looks like bandaid, but u see my mother is a veterinary and she has that. Its just like tape, but very very sticky, really strong stuff. But it doesn't have "little pillows" or something on the underside

I always use that stuff instead of normal tape, its damn strong

superart · 01-25-2004, 03:41 PM

you could do it like #rotor did. Im planning on doin the same thing. Check out his article, its really cool.

I DO care about looks, and I'm not that creative of a person. I really liked the link to the Overclocker's forum. That was very helpful, gave me quite a few ideas.

Stiffler, if you don't have access to a sheet metal brake then you can always turn the jaws of a vice around and use it. There should be countersunk bolts in the jaws. The back side of the jaws are smooth and the dimensions you quoted aren't all that much bigger than a 5" bench vise. You're bends won't be as sharp as a brake but it will still work. Be sure to think about what bends need to be made first and it's not that hard. I used to have to repair my race cars body with a vice before I got a brake

To avoid the jagged edges just use a fine single cut file and smooth out the rough spots, if you have any, and then use some 400 snadpaper and sand flat with (not across) the edge and your edges will look nice and professional.
.45 aluminum is best but you can get flashing pretty cheap at the hardware store. It'll be easier to bend too.
If you do use metal, cut a little short and file to the line, it'll keep the wavy edges from the snips from showing. It will also save you having to remake pieces like where the fan scres go, if you'd happen to overcut slightly.

Stiffler · 01-26-2004, 12:09 AM

Hehe, thanks for the reply. But, you're assuming I have a vice... :-D I'm only a college student with nothing more than a basic toolset, a drill, and my dremel. I'm going to have to find some more creative ways to accomplish this.

rocketmanx · 01-26-2004, 12:16 AM

I at least assumed you could get access to one

You can actually skip the bending and go to the hardware store and get some aluminum angle. They sell it at most hardware stores and it omes in varying half inch widths. You could get some 1/2" angle and cut it to length for all the corners and then you're just left with cutting rectangular pieces for the sides and top. No bending needed. Of course I'm assuming you can cut the angle to length. And also assuming you either have or can get acces to a drill for the holes.
Another idea would be to go find a plastic Rubbermaid container that's real close to the right size and cut and glue it to size. This only requires scissors but isn't gonna be very strong.

Stiffler · 01-26-2004, 12:23 AM

Is there any kind of liquid weld or something? Something that I can use to attach two pieces of metal together easily, and also provides a solid hold? I'll have to make a trip to the hardware store and see what they have. Thank you.

rocketmanx · 01-26-2004, 12:27 AM

JB Weld. Super strong. It's used to repair metal breaks of all kinds. So close to real steel you can even machine it. It mixes with 2 tubes like epoxy. There is also a JB Weld out now that has a 4 minute working time. The regular, stronger stuff takes a while to setup good.

If your a college student, you must have access to ladies' stockings

And with the rudimentary toolkit you described, you have all the tools necessary to do a #rotor style shroud. IMO, those look a lot nicer and more professional than just JBWelding a bunch of aluminum together.

Also, metal will reverberate more, so if noise is an issue, (if its not for you, I'm sure your roommate will have an issue with it) you should take that into account.

Where do u go to school? Most colleges have a shop on campus that students are allowed to use. Have you considered that?

Butcher · 01-26-2004, 05:12 AM

Eh, my shroud is made of sheet Al and it doesn't reverberate at all. Given shrouds tend to be 1-2" long and are cubiods they're pretty rigid really. I think the noise of the fans is far more likely to be an issue than the shroud itself.

yea, true.

rocketmanx · 01-26-2004, 07:48 AM

Plus fiberglass and resins suck to work with

Besides, He's already said he has no tools for cutting and it sounds as fi he has no drill either. Not much left to make things from with no tools

pHaestus · 01-26-2004, 09:29 AM

eh I have made many a shroud with aluminum flashing, a pair of kitchen scissors, and superglue to hold them together. Now that I have more tools I've upgraded to tin snips for cutting and pop rivets for holding but otherwise the same.

Here's what my ducts look like:

Made for a chevette heatercore using this pattern:

You could certainly make it from cardboard

superart · 01-26-2004, 09:34 AM

Verry nice

No, I have a drill and a dremel. I'm not not sure about the whole resin thing. I might look into it a bit more.

pH: What are you using to hold the shroud to the heatercore?

MadHacker · 01-26-2004, 03:24 PM

I have been thinking about the shroud i have to make.
using fiberglass and resing i beleive stinks real bad.
i saw someone making a case somewhere(on this forum mebe) using alluminum sheet and angle brackets /w rivits.
I think that would be ideal for my uses. not to hard.
