Jake, Looks like your a dog man like myself, I have a triple caged transit which I made cages for and ended up getting the welding and making fings bug...
yup its for my agility dogs (i only have two at the mo planning ahead). just been making it in my spare time in work. some more pics to come very soon.....
Nice job, but be wary of powder coat. My neighbour used to make cages for working dogs and found rust spots appear at the weldmesh joints after a short while where microscopic holes can be left by the powder coating. Galvanising is probably the best finish or maybe baked enamel paint. W/A
