The round holes were made using a 22mm punch. The punch was very easy to use and it gives perfect circle cuts. For the square and rectangle holes I drilled a hole in opposite corners and then used a jigsaw to cut the shape. Then I filed down the edges to make the cut the right size for the components (PIDs, timer, and volt/amp meters). The volt and amp meters also require a notch in the side for it to clip into. I just used the file to make the notch.
In order to punch one of the holes I needed to remove the grounding post. I used a rotary tool to cut the post off then grind it down flat with the rest of the panel. I will now be grounding through a screw that will be holding a faceplate on the front panel.
Hopefully the updates will start coming at a faster pace. For more information on the plans I am following please visit The Electric Brewery. There are wonderful write ups detailing every step of the way.
