While stripping down old computers at the shop I came across this CPU heat-sink. An idea instantly popped into my head to make a cooling head out of it. And since a lot of you guys seem to enjoy the custom how-to stuff,I figured I'd show you all how it's done.
Step 1: Measure the mounting area of another head and then mill that into the bottom side of the heat-sink.
Step 2: Measure the bolt pattern and drill them into the heat-sink. I drilled the center glow plug clearance hole too. Again this is done from the bottom side.
Step 3: Working from the top side of the heat sink now,first I calculate how deep I can go and leave a strong enough land at the bottom. Using a 1/4" end mill I plunge out the bolt holes to depth for clearance on the bolt heads. And add a chamfer to the hole the to deburr it and for cosmetic appearance.
Step 4: I use a 3/4" end mill and plunge into the center of the heat sink. And followed that with a 1" end mill. This clears out the extra material weight. Add a chamfer around the holes and the machining is done.
Step 5: The last thing to do is clean it up and check fit. Using the buffing wheel I buffed all the edges to give it a little shine and then washed it with some spray cleaner. Shazam! it fits
This concludes part 1. As it is I'm not satisfied with it. It's bit big and of course blocky. So for part 2,I'm going to add some shape to it. I'm just not sure what I want to do yet. Feel free to post some ideas if you have any,I can make about any shape
