This is my machined aluminum grill for the top of a case. It's cnc milled from 1/4" thick aircraft aluminum. It measures 7-1/4" wide, with 4.5" opening for 120mm cooling fan.

Unfortunately with expensive tools and equipment 90% of the people who come into this folder don't have access to.

There isn't much welding to do in PC modding... I spoz you could if you wanted to... not much of a need for it though.

He may find the work tells it's own stories in the pictures. I know I'm the biggest complainer, but here...it's easy.

This is done on a CNC machine where you just punch in the X,Y, & Z axis points. To make a circle, you just give it the inner and outer diameter and pick the order.

Looks to have the outer path cut with an 1/8th inch initial bevel pass, lift, cut out the center, then bevel that edge. Then change bits and drill the holes of the bolt pattern, then change bits, counter sink the holse 1/8th inch again. Finish up by chucking up on the inner circle (versus the plate) and finish the outside cut out. It's all in the machine's interface.

Sadly, we don't have CNC machines. But often someone else does. Schools are a shoe in and might do the labor for free and you just pay for the stock. Newer machines will often support .DWG drawings; where older machines are just point to point that use propriatary software and you put it in a floppy. You can call around to Votech schools or college shops and see what they have. Our highschool had an old Hurco and a newer water cutter (newer being early 90's) and a CNC plasma table...we'd just charge for the metal and did good work.

So break out the phone book and call around if you've got an idea in your head and would like to get it into action!

I would like to see how that modder's mesh was formed and is made to snap in and out though. Maybe it's just a pre-formed speaker grill painted to match?

Note the LINK in the post.

Note the User Name in the post.

Conclusion: The idea is not to have you follow a guid to build your own. Thus there are no destructions included. The idea is to pimp their product.

Thanks for the feedback and comments guys!!

Heres my suggestions if you want something cnc machined, laser or waterjet cut for your projects, I used these sources to make prototype parts when I first started out.

emachine shop, http://www.emachineshop.com,
these guys are the more spendy resource, but they provide free software download for designing and submitting your part(s) for quotes


For the following resources, you'll need to make a drawing with dimensions, material type and thickness before you submit it
:D

RFQ Work, http://rfqwork.com/
Online community forum of cnc machinists, laser/waterjet cutting specialists, and CAD Designers that allow you to post “RFQsâ€
