As a woodworking enthusiast with years of upcycling experience, I recommend starting with a sturdy plywood base. Measure your suitcase precisely, then cut the plywood slightly smaller—about ⅔ inch all around—so the legs attach securely and the suitcase sits flush.
Secure the legs or axles to the four corners of the plywood. Reinforce each with two L-brackets, screwing everything firmly into place for lasting stability.
Miter-cut trim pieces to fit perfectly around the plywood edges—measure inside dimensions for accuracy. Glue and nail them in place, extending onto the legs for extra support. Pre-drill holes with an awl to prevent splitting.
Prime, paint, or seal the legs and base for a professional finish. If working with potentially old painted wood, strictly follow lead safety protocols. Fill nail holes with wood filler, sand smooth, and apply final coats.
Raise the base, position the suitcase on top, and open the lid. Fasten it securely with screws sized to penetrate the suitcase bottom without piercing through the plywood below—ensuring a safe, wobble-free result.
