The chain collar has been completed. I originally spoke about my design for this here. The chain was an absolute bugger to drill through. with lots of coolant I finally managed to get her drilled, Then I struggled again to do the counterbores so that the bolt heads were hidden. I tried with a step drill but it broke within seconds. in the end I did the counterbore manually with a pencil grinder and a carbide bit. It worked a treat!
I love how in real life it looks seamless. It has completely captured the sense of permanence and Miss K appears to love it too!
