Ricc, events may have overtaken this, but my view is a bit different here. Given what's just happened, my guess is you won't forget to leave the shop door open again, and you're now focused on safety as much or more than anyone on this board. Your Jet 1642 is a fine lathe. The banjo parts that broke are less than $70 to replace, if I'm understanding your description correctly. There are probably thousands of Jet banjos like yours in use without problems. I'd replace the parts with OEM. You could put the hundreds of $$ you'll save toward your next lathe, if so inclined.
