I took folks advise and decided to go with bigger wheels. I searching for a set of wheels, I found 16" spoked wheels for $20-$30 each. I didn't want chrome, but that was all I could find. I figured I'd paint them black. As I was searching, I received an email from Cabelas and it had a Deer Cart on sale for $49 with 16" Black wheels !
I ordered it and it showed up three days later. It included a nice set of black 16" wheels, a few nylon tie down straps, 6 clevis locking pins an axle and a few nuts and bolts.....and a whole bunch of aluminum that can be used on various other projects!
The smaller wheels had an axle running the entire width of the cart.
This wouldn't do as it would raise the height of the cart too much.
I cut the axle that came with the deer cart for two "axle stubs". I welded these to a couple small plates of steel. And usiong 4 nuts and bolts, I bolted them to the sides of the gun cart.
The cart rolls much nicer now over rough ground. And I think it looks a whole lot better..........
