I'm working on building a simple table for a Big Green Egg. I have my plan that I'm copying but the change I want to make is a set of casters that will make it so I can roll it out of the garage and onto a gravel driveway, and of course back into the garage when through using it. The garage has maybe a 1" lip. I would like to avoid pneumatic tires as this over time will be sure to create a headache. Any ideas?
