Heck, I might as well share some thoughts...
I'm told that a plasma welder can create a plasma welder, but there's
only so much you can make with just a plasma welder.
I wonder if there is a set of materials, such that material A is malleable at
high temperatures but insensitive to, say, magnetic fields, while material
B is not malleable at high temperatures but becomes malleable when
exposed to a high magnetic field.
Tool tips made of these, could of course also be used to create non-tool
tip components (say, malleable at low temperatures) - including the
housing and manipulators needed to get the tool tips into position to do
their things, while themselves staying away from the high temperature or
Would someone with more experience than me at bending metal care to
