You start with a search for a suitable shopping cart which has to be one with a chrome finish. I found mine close to the loading dock area of a local grocery store and there it was next to a trash compactor. I went in the store and asked the manager if I could purchase it and was told I could have it for free. The generosity stemmed from the fact that current shopping carts have a powder coat finish so the old style chrome carts are no longer used. I would suggest staying away from the powder coat carts as the heat generated by burning wood in the basket will destroy the finish. The chrome finish will continue to look good after several burns.
Chrome shopping Cart
27" x 8' steel lath
galvanized steel drip edge flashing
galvanized steel corner bead
3 cookie sheets
1 pr galvanized steel hurricane ties
nuts and bolts
Step 1: Remove Plastic and Rubber
Step 2: Bottom Frame
Build a frame that will fit snugly in the bottom of the basket. For this I used a section of galvanized steel drip edge flashing which I found at the Habitat for Humanity ReStore location. A plug for ReStore… a great source of materials donated by contractors, big business and individuals. Use caution when cutting and bending the flashing as, I can tell you from personal experience, the edges are sharp. The purpose of the frame is to keep any embers from rolling out of the basket.
Step 3: Bottom Pan
On this step you can substitute with materials on hand e.g. a piece of sheetmetal, car hood.
Step 4: Line the Sides of the Cart
out so, to play it safe, I lined all four sides with steel lath which I found at the local builders supply store for under $9.00. The sheets are 27” x 8’ which is enough for all 4 sides and a piece left over that you can use for a spark screen cover. Steel lath is miserable stuff to work with so keep bandages on hand.
With large washers you can bolt the four sides of lath to the shopping cart.
Step 5: Spark Screen Cover
Step 6: Finishing Touches
The hurricane ties are bolted to the shopping cart and will support the hinges that connect the spark screen to the shopping cart.
