One motor almost finished

Mixed 7oz of silicon RTV with 1lb of iron filiings, it mixed in quite easily. Used latex gloves and applied it to the pre-formed copper tubing wrapped around the stator. I had previously machined in clearance on various places using a dremel etc.
It was tricky to do but I have it finished, I used two zip ties at the tube outlets to hold them in place before adding a lot of pure silicon to prevent the tubes moving around.
