Pard, that is nice work, for sure. That is what I like about guncarts, there is a lot of individuality in them. Yours is nice and your description of how it went together is first rate too.
I had a conventional cart, actually I still have it, but here on the left coast the latest fad is the 3 wheeled jogger cart variety. I went on ebay and there were plenty of them, but they were big bucks. I found one from Florida that was tapered in the front, I really wanted to make simple square or rectangular boxes. I wanted to keep it so that the whole thing would fold up too. What I came up with was two boxes and one was angled to fit between the frames. I don't want to go into that again, ever. I racked my little brain with a protractor and all the cuts went OK. I put a box up on the handlebars to hold misc and a water bottle and there you have it. This one came with a parking brake, which is necessary, because it rolls very easy. I can remove the boxes and quick release the wheels and it folds flat. It will go right into a small trunk. It is very light weight.
