This project started when we loaned out our garbage can to our neighbors and one of the flimsy plastic wheels that came on the garbage can had broken from what they had in the can that was obviously too heavy while taking out some trash.
I was excited, thinking I would make a cooler project out of this garbage can and make it into a SUPER garbage can! First off, I needed bigger, stronger wheels, then I searched for a steel axel rod to fit theses new wheels center diameter (which is a half-inch). 
Once I have these parts that I need for this project, I move onto my garbage can to see what I need to do to get out the old axel and the last remaining wheel. Once the old axel and wheel are gone I measured up where the new wheels and axel would be and I do a test fit. 
Now I’m thinking it’s not as easy as I thought it was going to be. So what do I do? I look around my little workshop. I needed to make some clearance for the bigger wheels and I remembered that I had obtained some box iron from one of my neighbors and they were welded together opposite of each other and they would work for just what I needed to make the clearance. Also, my half-inch diameter steel axel fits through this box iron, perfectly. 
Next was to get these things cleaned up and decide where I’m going to and how I’m going to mount them to the bottom. Once I have this measured and marked, I find just the right screws, nuts, and washers. Once I have them ready to mount I used duct tape to hold the heads of the screws in place while I go inside the can to put the washers and nuts on. I clamp on a pair of my vise-grips to hold the nuts while I turn the screw with the screwdriver to clamp everything down. 
Then I go to the other side and do the same thing. And while getting ready to screw down the other side, I put a level between the two with the steel axel installed so I know that it is straight and it will be level. Once it’s level, I install my wheels and measure how much axel I need before installing my wheels. 
Then once I mark my axel, I mounted it my bench vice, and I cut this axel with ease with my hack saw. Then I get my drill and drill 2 holes at each end of the axel for cotter pins. I get 2 cotter pins, I install my axel in my can, I install my new (bad boy) wheels and take my garbage can out for a victory cruise. 
It’s a much improved smooth-riding garbage can! It even has traction to go through the snow. LOL!
