Is it generally safe to leave the house/workshop when a tumbler is
running? Is it likely that a motor would burn out (or something)
and possibly start a fire? My workshop is in our basement, and we
have a smoke alarm, but sometimes I have to go out for meetings,
etc., and have often wanted to leave my tumbler(s) running. I have
two old and one not-so-old rotary tumblers and one old vibratory
tumbler. I’ve never had any trouble with them over the past several
years. Just wondering.
