So I got excited and rather than waiting on all the bits from China i ordered to polish the crap out of this, I decided just to put it into service. I am still waiting for the right sized lower springs to arrive from China, these ones i cut out of ones i bought from Bunnnings (hardware store in VK) and they do not sit correct. But, the key works, its nice and smooth and even though its not polished to within an inch of its life, i am very happy with how this turned out. I learned a lot and if i do another one, I know i can make it better than this one by a long shot.
