hello, i am new to the site and was unsure as to what category to put this under, but heres my problem.

I have to do a final project for my woodworking class and am haveing a bit of difficulty finding a set of FREE design plans for a wall mounted gun Rack or Cabinet.

It needs to hold 4 guns.( i would also like it to hold my compound bow but i am unsure how to do that) also the guns will have scopes on them.
It needs to have a locking ammo compartment.
It also needs to be something relativly easy to build, not something extremely complex.

Any ideas or advice would be greatly appreciated!
Thanks!
