im going to cut a window in the shape thats outlined in the picture below, and i was wondering if i should use a dremel and do it myself, or go get it laser/water cut.

also, does anyone know where i can get a round 70 mm fan?

I would use the dremel, but leave some material inside the lines so you can clean up your lines, i dont knoy about the cutting using the NC equiptment but i'm sure it will be expensive. I right code for a millwork shop in Ontario and a one time program like that would be about 200 bucks even under the table.
 
For cutting windows i prefer using a jigsaw with a metal cutting blade, its cleaner and much faster than a dremel. just remember to use masking tape and clearly mark your cut.

you can find a 70mm round fan at allied electronics or a similar vendor.
 
I'd use a combination of jigsaw and dremel. I agree with Lord P that a jigsaw is much easier and quicker than a dremel for cutting something this big--especially since you have some relatively straight lines. The curves, I'd round out with a dremel.

Your other option is to send it to Laser Precision Cutting. I used these guys to cut a pretty intricate design for my side window and they did it for less than $75 shipped.
 
my friends's dad is firneds with some guy who owns a laser/water cutting shop and he said he could get it done for like 10 dollars, but i dont want to wait much longer, and i think i could use the experience cutting it.
it was a free computer anyways.


i already masked it too, its just sitting in my room waiting to be cut.
 
Laser/water cut for $10? Go for it. For that price it's worth it just to save you time & materials.

Other than that I agree with post #4.

P. S. - any particular reason you want a 70mm fan? If for that window why not make it larger? 120mm? Interference with internal components perhaps?
 
i want to put it in the round part in the middle, and its a little bit bigger than 70 mm.
i found some, but theyre not round

Still, you are designing it. Why not make it at least 80mm to give you a shitton more fan options. If it were me I would make it 120mm for quieter operation.
 
i was think about it, but i would have to completely redo the middle to get it to line up.

i might just buy a 60 mm and cut a hole so just the fan is visible, and not the mounts
 
How long would it take to redesign the center area, maybe 2 minutes?

Don't go with a 60mm fan. They create too much noise for the given airflow (CFM). They do create higher static pressure per CFM, but that won't do you any good in that application.

Your side window project looks very similar to mine. Here are a couple images if you're interested :

Laying out the design & making little cardboard templates :



All cut & deburred :



New window & high flow 120mm fan installed :



I have extensive metalworking experience & would be happy to give some pointers which may help your project go more smoothly. Please feel free to ask any questions. :)
 
i mght just put an 80 mm on there, but i already have all the tape on it it, and its has all the sharpie marks on it.
id have to completely redraw the crossbar to fit a bigger fan.
i could put a duct in the hole and attach it to a bigger lighted fan i suppose.
 
i have the window hole pretty much finished, and now i need to know what type of primer/paint i should use.
i was planning on a shade of orange, with a blue interior.
this color orange
this color blue

Wow thats a amazing job, I wana hear your pointers PM me! Thanks!
 
If you find a 70 mm fan, you could use 2 corners to mount it, then grind off the other 2 corners so they wouldn't be seen sticking out
 
i was going to grind off all the edge on an led fan and glue it on their somehow, but i still have no clue on how to poaint it
