Thanks Bert,
I appreciate the advice. Do you have trouble igniting the insulation with
the plasma cutter or do you disassemble prior to digging in?
All the best,
Rick

Hi,
I had quite good success using a plasma cutter (available for quite cheap at DIY
stores - needs an air compressor as well) to cut out the magnet coil (to use as
display item for the original customer) and to separate out the aluminium from
stainless and copper parts. However it's a good day's work, so don't expect a lot
of money from the process. But it's good to know it will all go to proper metal
recycling.
I don't think the coil material is really recyclable though as it's a wild
material mix of copper (wire), niobium-titanium (supercon), stainless (overbinder)
and aluminium (formers), tin (joints) as well as resin, plastic etc ...
I haven't tried cutting it open with an angle grinder and cutter disks after heariing
it's not that funny... But that's the better way if you want a "full display" piece
by cutting a hole into every layer. People have done amazing jobs at this, adding
some LED lighting to show the different dewars 8-)
Cheers
Bert
