NEW DESIGNS and model numbers on Monday
ALL READY
3 versions
Horizontal coil orientation x 1
Vertical coil orientation x 2
Resolve issue of physical interference on one coil in location, only seen after many hours analysis and viewing various iterations.
Done major detail redesign of COP Adaptors (internals, spring system, fixing etc, and external) and associated items (mounts etc).......
all good 
now this is 100%. Thank god for CAD model no way you could do this without it !
Will include dimension critical items along with the three pics of the 'options' well only Horizontal and Vertical will have different dimensions.
Some of the internal detail is different in the COP, I wont be sharing this for public consumption here

but I guess eventually customers will post it ???? Either way not easy to make regardless let alone check so good luck to copy cats
