re: I'm a student in need of some help :)

I know it’s late for a reply, but let me assure you: most woodworking projects are made without plans or with rudimentary sketches just sufficient enough to tackle panel cuts. If you want to make a gun cabinet, the only required information is how many guns, how far spaced they are and how long is the longest one. That’s the starting point and only you can find the answer to that.

I’m not jumping on you, believe me, but this isn’t rocket science. The only thing that separates fine cabinet makers from hacks is the love of making sawdust and an eye for detail. If you love it, it will be awesome despite any of your own percieved flaws in the product.
