yes it seems soWon’t the heat degamnetize ?
do i need a magnet inside ? i'm thinking of labs with liquid in flasks being stirred by an external rotating magnet. would (a) steel blade(s) follow an external one ?
Why, if you mean one with balls, races etc ?Also, it would still need a bearing.
loads are almost zero, steel on brass or copper shouldn't be a problem running dry.
it doesn't really need a high speed to move some air around.
if required high temperature greases do exist.
anyway, pop rivets, find a large one with tension rod of about the size of rod you have, nip it up until it just locks in the panel, might be better to add some washers - you only want to tighten until just begins to bulge, way, way before the snap point and before it fully balloons the end.(tends to bend and shrink the hole.)
release the gun. push the rod back and out.
find a suitable rod and assemble ... ...
