So the chassis of this bad boy is a Case Gard Flip-Top Rifle Ammo Box Part# RS-50 (I paid $4 at Karl's Hardware in Rosamond). I put a piece of 2" x 3/16" thick Felt in the lid to protect the plugs and cut a piece of poster board for the labeling. Long story short I have about $20 into the two of these and unlike a standard sparkplug tray they have lids and the plugs fit really well.
Also a heads up, these boxes are set up for the M40J plugs that we run for air racing. They may not work for your plug of choice. I would recommend finding a local store that has a good selection of these cases and checking them out they are great for all sorts of stuff, and cheap.
What are you working on tonight?
