I bought in an auction 8 block office drawers for 70 euros to serve as storage cabinets in my workshop.
The stationery drawer is too large and a drawer block occupies too much space for the available storage space.
I then decided to turn two cabinets into something like a workshop servant.
Step 1: Elimination of Large Drawers
Step 2: Recovering the Rails of a Cabinet
A large drawer occupies exactly the place of two middle drawers.
So I replaced it with two medium drawers recovered in two other cabinets
Step 3: To Stack Two Cabinets
To stack two cabinets, remove the wheels from one of them.
Drill 4 holes in the lower block to insert the axles of the castors.
Step 4: Stacking the Two Cabinets
Put rails and drawers in place
Step 5: And Here Is an Optimized Storage Space
