If finding a used aluminum cart or learning to weld isn't an option, you can build a highly effective alternative using a simple rolling cooler and basic rod holders. This cart works exceptionally well for piers, lake banks, or catfishing, and can even handle the surf with a little extra effort.
Step 1: Template and Drilling
Use one of your rod holders as a template to mark where the mounting holes need to be on the outside of the cooler. Position them carefully so they don't block the cooler's handle or interfere with the wheels. Once marked, drill 1/4" holes through the plastic walls. [00:01:02]
Step 2: Secure the Holders
For each rod holder:
Push your stainless bolts through the holder and the cooler wall.
On the inside of the cooler, add a fender washer before the nut. [00:01:10] This distributes pressure and prevents the hardware from pulling through the plastic if the rod is yanked.
Tighten everything securely with a wrench.
Step 3: Waterproofing
To ensure the cooler remains insulated and leak-proof, apply a dab of Marine Goop over each nut and bolt head on the inside. This seals the hardware and prevents cold air from escaping. [00:01:45]
Step 4: Add the Remaining Holders
Repeat the process for the other four holders. Five holders generally provide a good balance for various rod setups without overcrowding the cart. [00:01:14]
