G'day folks,
Perfectly possible, Norm. There was even an ODK member a while back, who fabricated an entire SB45 replica chassis from stainless steel!
Edit: Just found that thread;

The common grades like AISI 304 and 316 undergo 'work hardening', and that makes them more susceptible to cracking than mild steel.
