Besides the wood, the only thing you need is screws. Using the pocket hole jig and 3/4" wood, you use 1-1/4" screws. Buy fine threaded screws ifd you are using the good woods. If you are using real cheap pine, use coarse threads.
Do you have a fax number that I can send you hand drawings?
I really suck at Paint. The only other thing I have is Autocad. I can hand draw stuff extrememly quickly. I think we can satisfy your desire to build the 120 stand initially with a removable cabinet. I will play with some drawings.
