hopefully this post will prove useful to somebody.
about 6 months ago i bought a delta 14-651 - read a review on benchtop
machines, it was highly rated, on sale, so i did it.
anyway, when i first turned it on it sounded odd. a bit of
metal-on-metal grinding noise, which i quickly determined was in the
bit. of course, given the nature of such machines, i immediately
assumed that i set up the bit incorrectly, so was careful to make sure i
used proper spacing, etc. still sounded bad. bought a new bit - still bad.
used it for one project, blue-tipped the auger in one job. wasn't
pretty. a month ago i decided to find out what was wrong with it, and
my dial indicator told me that the motor shaft was wobbling by 10 thou.
took it in today to local delta dealer, they agreed with my assessment
that the motor shaft was shot, and they are getting me a new machine.
this was my first real out-of-the-box dud. hopefully others have
had/will have better experiences with this machine.
