First off, my wood working skills rate about a 2 on a scale of 1 to 10. Have always been interested in woodworking, but never really tried it. So this project is also my first real shot at building something were measurements are down to the 1/8 of an inch.
First off, I purchased a router. Picked up the DeWalt 618 kit. I'm also using this project to pickup a few nice tools that I plan on using in the future, so for the most case I'm not going the el cheepo route. Also picked up a router book, since I've never used one before, figured I ought to learn the basics.
Went to Home Depot, purchase 2 4x8 MDF 3/4 inch boards. Had Home Depot rip cut the 2 panels to the exact width of the back of the unit (saved me a lot of cutting, +100% dead striaght), had to do this anyway to get them to fit in my Explorer.
Then transfered the diamensions of the unit to the MDF.
