RE: HELP WITH MACHINING & THREADING TUNGSTEN
Now, is the crumbling occurring when you machine to an external corner? If so, use a support made out of a machinable thermoplastic material such as nylon. Also, use a large chamfer that is machined before the adjacent surface is machined. This chamfer should be sufficiently sized such that there is some metal still left after the turning cut is complete.

If you don't have this reference, then you really need to purchase it, especially when machining difficult materials like tungsten.
