A local specialty ammunition manufacturing company asked me to design and build some 250-round .223 Remington ammunition crates for their trade show booths. Here are a couple of pics of what I came up with for them.
The entire project is made from 1/2" MDF for the boxes, and .175" thick Masonite for the sliding lids. Each box can be made from a single piece of MDF that is only 26" x 16", and the Masonite lid is cut from pieces even smaller than that. It probably costs about two bucks to build one of these ammo crates.
Virtually the entire project is cut out with a .250" end mill. The thin channel that is cut for the sliding Masonite lids is cut using a specialty .0937" end mill from Precise Bits, everything else is cut out using the .250" end mill.
Cut time for the MDF parts is about half an hour, lids take about fifteen minutes counting the custom logo and caliber information. No fasteners needed, only wood glue to assemble them. Finish sanding and application of stain and poly takes about another ten minutes.
I can send you the PartsWorks file if you want to try cutting them out yourself.
