Jet Table Saw Calibration accuracy

I just purchased a Jet JWSS-10 (aka "Supersaw") 10" hybrid table saw. This
is the first table saw I have ever owned.

So as I was unpacking it and admiring all the oiled heavy cast stuff, I
found the factory inspection record. Jet obviously wants you to see this as
its prominently packaged in its own plastic sealed envelope with the
inspector's hand-written measurements.

Run-out of Arbor Flange
Allowed 0.0008 inches
Measured 0.0008 inches
CHECK

Minimum blade height
Allowed 3 1/8 inches
Measured 3.13 inches
CHECK

Parallelism between blade and mitre slot
Allowed 0.0118 inches
Measured 0.054 inches
UH-OH!!!!!

Yep, according to the inspection record, the last measurement is 4.5 times
greater than allowed. Now if this was a $99 eBay special saw, I wouldn't
bat an eye. But I paid for a little precision here. I thought I must be
misreading it, or it must not be that important. I called the dealer, who
is also an authorized Jet repair shop. Their saw guy was speechless. He
acknowledged it was out of tolerance. He has never seen the factory actually
measure it out of tolerance and ship it anyway. Just to be sure, I scanned
the inspection record and faxed it to the dealer. He agreed that I was
reading the number correctly.

So hopefully we will get this resolved. Are there any wood tool engineers
in this conference? Is this difference really important or is it splitting
hairs?

Thanks,
Bob

I can adjust the hood alignment on a new car as well, but I don't think I
should have to....

Here is the final outcome of my quest to confirm an in-spec Jet supersaw.

The owner of the dealership called me and set up an appointment to come to
my house. He drove over himself and brought the equipment to check the
blade parallelism to the mitre channel. Well, not only was it good, it was
virtually perfect. There was no discernable difference in distance between
the front and back edge of the saw blade. He said he had talked to the tech
at WMH tools and the story of my calibration report was all over the office.

The conclusion is that the inspector was having a bad day or his/her mind
wandered when they wrote down the numbers.

I am a big believer that negative experiences form the framework against
which we measure good experiences. This was an unfortunate experience, but
the factory and the dealership both acted honestly and professionally, never
trying to cover up or hide anything.

FYI, the dealer is The Cutting Edge. The owners are Steve and Teri LeGrue.
I have no affiliation with them - just hope to be a long term happy
customer.

It is probably adjustable, it is on every other table saw I have ever
seen. Read your manual and see, if it is it will be good practice for
the next time you have to remove the top. It is probably easy, just
loosen the table bolts a bit, and whack it with a dead blow till it is
right.

Hum...sounds like the fix would be for
a tech to come out, loosen the bolts holding the trunnions
to the table and, rotate the cutting mech a bit.
Assuming you bought this puppy locally, it seems
like the local dealer could do this in a couple of hours,
onsite. Otherwise, perhaps Jet will have a tech come
out and do it.
Actually, this is the sort of thing that I would
shake my head over, and, fix myself, as it is likely
nothing more than the above adjustment. However, if you
are not handy with tools and machines, it WOULD be
a better thing to let a qualified tech take care of it.
There is a lot of power in a tablesaw, and, mis-alignment
can project wood back at you at frightening speeds,
quicker than you can blink.

That sounds like fairly admirable customer service to me. I
have some contact with production manufacturing, and, while they make
great efforts to ensure that stuff that is out of spec does not get
out the door, it does happen. Like cutting your fingers off with a
tablesaw, it only takes one lapse of attention for an item that SHOULD
have gone back to rework to get put in the "ok" area. Once there,
pretty much no one looks at the attached paperwork, as it assumed that
the product has made it through inspection ok, and, is ready to go.
It will go out whenever it floats to the top.

Yea, that is one thing about the "bigger" tools. The
more industrial they are, the less likely they are to come
with tooling. THere are folks out there who have entire
businesses based on making tooling for industrial mills,
saws and other forming tools.

Pack it back up and tell 'em to please coordinate pick-up when they deliver
you your new saw.

Don't even mess with it....

Good luck

I faxed the report to the dealer and factory. The factory just called me
and said that level of inaccuracy should never have been shipped. He said it
was so far off, he wasn't sure that it could be aligned, but he said the
solution was replacement. He asked me to coordinate with dealer for
details. I spoke to the dealer and he agreed that replacement was
appropriate. He said however, that the measurement was so far off that he
wanted to come out and check it. He said the worst he has ever seen in
dealing with Jet over 10 years was about 10% out of tolerance, not 450%. He
said that if its out of tolerance, they will replace the saw.

He asked me if I had laid a combination square against the blade to check it
myself. I laughed. I don't even have a blade for the saw. No one told me
it came without blades when I bought it. I guess I was used to buying
portable saws that always come with one starter blade.

Dave,

Thanks to you and others for your quick replies. I am pretty handy with
tools, provided I have the right ones. I have nothing that would measure the
calibration accurately. Since I posted my original message, the local shop
told me they could come out and adjust it, if necessary, but they wanted to
contact the factory first and see what their resolution would be. They said
it takes a few hours to make the adjustment. They are as unhappy as I am
that the thing inspected out of tolerance and got shipped anyway.

I found instructions in the manual that encouraged calling Jet directly for
any problem, including shipping damage. So I did. The telephone went
straight to WMF tools customer service (WMF is the merged Wilton-Jet
companies). In 15 seconds, I was transferred to a technical service rep. I
must say he listened intently and was very concerned. I am so used to
getting "offshore" customer service these days, it was a real pleasure to be
connected to someone with a deep Alabama accent.

When I told him I had contacted the local dealer, he said "I'm glad you
called us because this is the kind of thing we want to be involved with". He
said first thing he was going to do was pull two saws off the line and see
if they had some kind of quality problem. He said they would do whatever it
takes to make it right, including sending a new saw. As with any good
customer service, he set my expectations that it will take a day before he
can get back with a resolution.

I'll report back what happens.

Bob

Feeler guages? Wow, I had not heard that term for 20 years. I used to have
good set of them, but must have lost them when I sold the last car with

Did you measure it yourself? Maybe the guy forgot a zero at the
beginning. You know, since everything is carried out to 10 thous and
that's only carried out to thous...
