Sorry guys, computer man installed a new 500gb Hybrid SSD hard drive on the lappy over the weekend and its back in action now.
The new cell seems to be about 1mm larger diameter than the tube.
So a bit of engineering is to be had to mate the cell thread to the tube thread in a secure way. The tube is now at a CNC workshop in Southport.
So here are a few pics of the cell and tube before going to the shop today where it will be for about three days.
