Project Black PC (part 6)
Sorry about the dull name.
22nd March 2007

There is no point mounting a large fan shroud on the side of a PC unless the air can flow into the case. So this requires some cutting. I have drilled and tapped the holes so I can line the whole assembly up properly. |
 |
I am going to use a nibbler attached to a power drill. This cool little tool nibbles (as it name would suggest) nibbles away at the sheet steel at high speed. However doing it by eye is a little tricky so I decided to make a template that the head would butt-up against and guide me around the shape. |
 |
First I took a pint glass (It doesn't have to be a 2004 Twickenham Beer Festival one) and marked the radius. |
 |
Nice neat curve. Everything between the curve and the corner has to go. |
 |
Do not try this at home! |
This belt sander is adapted to lock in to my work bench. It could get very messy if it got loose with the power switch locked on. |
 |
Must remember not to stand this side. That tube is where all the dust comes out. |
 |
Action shot! |
 |
After some quick measurement I found that if I line up the guide with the bottom of the cutting head right to the edge of the line I want to cut, when the wider part of the head is against the guide it will be cutting right on the line. Most impressed, that must have been designed in. |
 |
The panel all marked up to show me where to put the guide. As I only made one corner I will need to keep repositioning the guide, I thought this would be a good short cut and save the trouble of making an exact size guide. |
