Best way to precisely cut a Sheet Metal Computer Case for a cooling mod?
I'm modifying a computer case for my brother. We are discussing several mounting options and are needed to find a way to easily and precisely cut the sheet metal of the case. And inexpensive too if possible (under $100).
We need to be able to cut out precise squares without damaging the metal around. For cutting out circles, we have figured on wood/metal holes saws.
One thought is to get a router attachment for my dremel and some rotary file attachments.
Find any asbestos in your Eureka Ez Clean vacuum lately? have another look behind the hepa filter.
It says referb and then has a sticker on it.... wonder why containers are coming from East with asbestos plates inside and shiny stickers outside?
Take your project to a sheetmetal place and they will probably cut it out for free for you if you buy the metal there. Make it out of copper it would be freaky cool.
Did I tell you I found 2 pieces of Asbestos type material in my Eureka Vacuum I bought. Pretty odd, going to get them tested for sure!
How to Drill Hard Metal
Drilling a hole into a piece of hard metal, such as steel, requires a different approach than drilling into wood or softer metals. Hard metals dull the drill bit so quickly that the bit cannot penetrate all the way through the metal. Instead of going through several drill bits just to create a single hole, you should employ a better technique. With the proper drill bit and technique, you will find that drilling hard metal is no more difficult than drilling other materials.
Step 1
Insert a cobalt drill bit into the end of a variable speed drill by following the instructions for the drill. If you are using a keyless chuck drill, as most are, simply turn the end of the drill collar counterclockwise top open it. Insert the drill bit with the sharp side facing outward and turn the collar clockwise to secure the bit.
Step 2
Lay the piece of metal that you are drilling onto a flat, stable work surface such as a table, the ground or between saw horses. If you lay it on a table or the ground, place a small block of wood under the metal in the location where you will drill the hole. This prevents the drill bit from damaging the table or getting dulled by the underlying surface.
Step 3
Pour 1 tsp. of oil onto the area where you will drill the hole. You can use any type of oil desired, but plain motor oil works fine.
Step 4
Set the speed of the drill to a low speed and turn it on.
Step 5
Place the drill bit against the oiled location on the metal and press downward with gentle pressure to begin drilling the hole. Take your time and allow the bit to slowly cut through the metal.
Step 6
Pull the drill bit out of the hole when it penetrates the metal and turn off the drill.
