Years ago when I lived in an 800 sqf condo I did my woodworking at a TechShop in downtown San Francisco. This meant I was carting my hand tools back and forth from home to shop so I built Mike Pecoviches portable tools chest from fine woodworking.
Once we moved to a house i stopped using Tech shop and it ended up living on a side bench for tool storage and I never added the dividers and tool storage.
This summer we will be spending two months in Wyoming which will include at least a few woodworking projects so I decided it was time to set it up with my minimum tool kit using scrap wood from the garage. The dividers were left overs from a humidor project a friend gifted me when he moved and the saw lock is from an old tool chest i found on the side of the road years ago (it is really light and strong so i suspect old growth redwood stained by the water damage that ruined the chest).
I will probably do a bit more adjusting, especially in the drawers, but overall this neatly holds the tools to do almost anything. We will see how it holds up to the drive.
