some tooling . SAhe needs some mandrels made that are a piece of
tungsten rod welded/brazed to a stainless steel handle . The join is not
subject to the full heat of molten glass . Am I right in assuming that a
TIG torch set on DCEN will melt and fuse these two metals without filler
? What filler is recommended ? I have on hand 308 309/309l , and some
312 in various sizes . I also have some ER70S2 on hand . She indicates
that these must be pretty straight , no wobbles when they are spun or
rolled across a flat surface . I'm thinking a long vee block with a
cutout in the middle , maybe a spring on one end to keep things pushed
together . We're getting into uncharted territory here for me , I'm open
to suggestions - that pertain to the task at hand , please .
