Wasn't really happy with the selection of metal boxes available for purchase. I decided that to get everything I wanted, I would have to make my own box and in order to make a box correctly, I would need to purchase a good Box Brake. I purchased a Box and Pan Brake from Harbor Freight and it arrived yesterday. Using a purchased metal box as a template I made the top half of the box with a size of 5.5"x6.75". The box depth will be set later. After test fitting the LCD and keypad, it looks like everything will fit as needed.
