Step 10: Drill Some More
Now, we need to drill holes on the side of the case. Two of the holes will have a 3/8" diameter and be for the audio jacks (on the left and right sides). The other two holes will be for the DC power adapter jack and an on/off switch (on the back side). For these two holes, you should obviously use drill bits appropriate for the size part you have (I recommend drilling test holes in scrap material first). As you can see, I also made an extra hole for a switch I didn't end up using (you can ignore that unless you have a use for it).
To figure out where to drill these holes I temporarily installed some potentiometers, then using tape stencils and the parts to be installed, I figured out the exact position of the hole on the inside of the case. Once I had this in place, I lined up an identical stencil on the outside of the case. The theory here is that the hole on the inside matches the hole on the outside, such that when you drill through, your part should fit in precisely where it needs to be.
I found what works best in this case is if the 1/4" audio jacks are situated between and "above" (when looking down inside the case) the two rows of potentiometers (and also far enough from the edge to account for the lip of the lid). The switch and power jack position are less critical, but should also be situated "above" the potentiometer.
Once all of your tape is in decidedly place, drill your holes.
