For this next step, I did not get pictures of me drilling the plastic, but I drilled two holes side by side in the middle of the arm bars. I then marked the heatsink with a sharpie where to holes were. I then drilled the hole with the matching drill for the 8-32 tap. Then, tapped the holes...

Here is the heatsink mounted on the arm bars... Mind you, I ended up using fender washers and nuts to finally mount it, these are building pics!

Once that was complete, I drilled the hole for mounting the 10k potentiometer. I chose to mount it in the back of the base, where it is easily accessible. The bag the pot came in mentioned what size drill bit to use, I don't remember but I think it was a 5/16"? If you buy the linear potentiometer from RadioShack, it says on the back... Also, you may notice there is an extra hole next to the pot. That would be a screwup on my part, the original hole was too close to the foot, so I had to re-drill. In the 3rd pic, you can see the hole I drilled to get the wires out of the base and into the back equipment shaft.
