Hi miseree.
You will need a hammer & screwdriver or small crowbar to pry apart the crate. The mill will be inside, bolted to the bottom. Inside and in the styrofoam will be all of the tools--especially the big wrench--that you will need for disassembly. Bring some shop towels or a roll of paper towels to wrap all the greasy parts in.
The crate is not that large & HF will help you to load it. If you have a truck or SW, or it will fit in trunk--and help at home, you don't need to disassemble at all.
If it won't fit, then the easiest disassembly is into two parts: the base/table assembly and the column/head assembly. To get there, just remove large nut at base of column. (while supporting head so it doesn't fall over sideways) This gives you two parts about 75 pounds each. Again, HF will help you load these after you disassemble, but you will need help at home.
If you have no help at home, you will want to separate base & table, and maybe column/head--although if you can lift it, better to leave head on column.
Removal of grease is easy with brushed kerosene and paper towels.
Good luck!
CR.
