Automatic Chain Sharpener - under $300
By: Philbert Date: December 17, 2018, 9:25 pm
---------------------------------------------------------
I have heard rumors of an automatic chain sharpener 'under $500'
for a few years. Saw some info on one for just under $300 today:
TEMCo Industrial FP1000 - Automatic Chainsaw Sharpener
Have not used one, or even seen it in person. Following info is
from manufacturer's materials.
- works on full comp chain only
- looks like you can set top plate angle only (head tilt angle
and 'down angle' fixed?)
- does depth gauges with separate wheel (interesting way to
gauge them)
- works on 12V (off of car battery) or 120VAC with adaptors
- looks like proprietary grinding wheels (?)
- no info if wheels need to be dressed, etc.
- $299 on eBay

More info in series of pretty clear YouTube videos:

Looks like I might need a 'cheat sheet' to program it for at
least the first few times. But 1/10 to 1/20 the price of the
next automatic chain sharpeners that I know of!

First Impressions
Received a demo unit yesterday: very good first impression. It
was double boxed for shipping, with die-cut, closed cell foam
packaging.
The sharpener itself looks well finished and appears to be a
quality product. The main housing appears to be an aluminum (?)
casting with plastic guards. It is roughly about the size of a
loaf of bread.
It comes with LOTS of parts! 5 power accessories; 3 hex key
wrenches; 2 grinding wheels (sharpening wheel comes installed);
2 wheel wrenches; a chain weight; a wheel alignment indicator; a
depth gauge measuring tool; a feeler gauge; mounting screws; and
a user's manual. If I was going to keep this grinder I would
find or make up some type of pouches to keep the power cords
together, and the small tools together, so that they do not get
lost.
The manual is pretty clearly written, but technical. If you are
not into reading, you might have some trouble with this.
Watching the YouTube videos really helps. Hopefully, TEMCo will
have the manual up on their website to download. They should
also make the user videos available for downloading, in case
someone wants to view / refer to them later, and has limited
Internet access. I may make some editing suggestions and pass
them on directly to the company, as they do not really pertain
to this thread.
I need to make a base for this (to clamp down to temporary work
surfaces), and review the videos, before I try running any
chains, so it may take me a few days.

Seems more like homeowner use then someone that is doing chains
daily.

Reading this is alittle scary.
Somebody on AS said = (I bought one of these and received it
last week. It works well except when it ground the wrong way on
a tooth for no apparent reason and ruined the tooth. Good thing
I was standing there and could stop it from continuing.
Hopefully this was a fluke and doesn't happen again. Now I need
to get out and dull a couple chains and try it again.)

Philbert's Summary - Part 1
I like the idea of an automatic chain grinder: it should save
time and increase cutter consistency. I am really impressed that
TEMCo was able to develop and produce this model for the price
that it is offered at. Looking 'under the covers', the design is
both clever and elegantly simple.
Comments posted in these threads have provided the company with
a lot of invaluable feedback, advice, and suggestions from a
dedicated group of chainsaw users and potential customers. E.g.
this type of device should cover the full range of common,
consumer saw chains, including:
· 1/4 inch to full-sized 3/8 pitch chain;
· 0.043 to 0.063 gauge chains; and
· skip tooth chains, or at least the extra space common on many
odd length loops.
'Automatic', of course, means that it runs unattended once set
up. This is not, "Alexa: sharpen my chain!" technology. A user
still needs to understand what a properly sharpened chain looks
like, and how to set the controls, in order to get satisfactory
results.
TEMCo generously provided a unit for evaluation in these forums.
For reference, no one else asked to participate in this review,
per the guidelines posted. In fairness, the company's offer of a
'one-year satisfaction warranty, with shipping paid both ways'
on eBay is, perhaps, a better offer.
I hope that others who try and use this product share their
comments, experiences, and recommendations in these threads. I
also hope to continue using and evaluating it further, and to
take it to other events for folks to try. Longer-term feedback
can only come from extended use.
An evaluation of the product really falls into 2 categories: the
product itself, and how it compares to other chain grinders or
sharpening methods.

Philbert's Summary - Part 2
Overall, the TEMCo FP100 feels like a well made and well
finished product. The design is compact and the packaging is
very professional. Many photos are posted earlier in these
threads. The manual feels a bit more like a work in progress.
Use of the grinder was not intuitive for me, however a series of
YouTube videos were very helpful to understand basic operations.
Familiarity came with use. This might vary with the type of
previous sharpening experience a user has. I have sent the
company many comments, beyond those that I have included in
these threads, and continue to send updates, occasionally.
A key set up issue I had was with the 'Length' and 'Pitch'
knobs. Because these adjustments are mechanically related, and
the design allows the knobs to be rotated past the limits of
having any effect, it is confusing when adjustments apparently
make no difference, or when they have disproportionate or
unintended results. Cutting viewing 'windows' to see what these
knobs actually do was a big help for me, but something I still
have to think about.
The 'bubble buttons' on the digital display panel also have a
learning curve, since they are multi-functional: hold them a
little too long and they do something else. Periodically, I have
to turn the power 'Off' and start over.
The 'Depth' knob is pretty straightforward. However, the
cam-operated, gravity feed of the grinder head sometimes made
this confusing, when the wheel would not travel as far as
desired; this turned out to primarily be an issue with the
grinding wheels.
In my mind, the wheels of a grinder are analogous to the chain
on a saw: their quality and condition are critical for good
performance. The red/brown, fine grit, vitreous, OEM grinding
wheels cut well when new, but soon became glazed, even though I
routinely clean chains before sharpening. They were also
challenging to dress, compared to conventional grinding wheels.
Glazed wheels, in turn prevent the head from grinding to the
desired depth during the programmed cycle time, resulting in
inconsistent cutters.
Eventually, I was able to learn how to dress the wheels
appropriately; this is information that should be included in
the instructions. The optional CBN wheels have performed well,
during the limited time that I have tried them. Because they are
offered in 2 widths (1/8" and 3/16") it is also easier to get
good cutter profiles for a variety of chain pitches in a single
pass.
Changing wheels should be more convenient, as this is required
for different pitch chains (with the CBN wheels) and when
adjusting depth gauges. The small screws securing the guard
require a lot of turns, and are very easy to lose.
With some practice and experimentation, I was able to sharpen
cutters, clean out gullets, and get acceptable chains. If
starting with a hand filed chain, it may take a few passes to
'even up' the cutters: after than, maintaining edges with the
sharpener is easier.
The FP1000 could be a good choice for a saw user seeking to
sharpen edges dulled from normal use; who runs a limited number
of chain pitches; who is satisfied with conventional cutter
profiles; who is technology minded; or just appreciates the
automated function. Frankly, it is kind of fun to watch, once
you have it 'dialed in'.
This grinder is for personal use: it is not the unit to start a
chain sharpening business with. It would not be as good of a
choice for users demanding custom angles or cutter profiles; for
those restoring 'rocked' or damaged chains; or for those not
comfortable with technology.

Philbert's Summary - Part 3
Hand filing chains requires some knowledge, skill, and
experience for proficiency. Grinders generally produce more
uniform cutters, and are faster when a lot a material needs to
be removed. In fairness, it takes some knowledge, skill, and
experience to become adept using most grinders as well.
Inexpensive, manual chain grinders can improve cutter edges with
standard angles, but often have limited power. Other automated
chain grinders cost more than my first few cars! It is most
fair, therefore, to compare the FP1000 to other grinders in a
similar price range.
The Oregon / Tecomec style grinders generally have more powerful
motors and larger diameter wheels. Depending on the model, most
offer a greater range of angle options for custom cutter
profiles, especially 'hook' angles, for those who desire those
options, and understand how to set them up.
With the right wheels, these manual grinders will work on any
(round ground) chain. They have the power to grind away a lot of
material when fixing a damaged cutter, or re-profiling a chain.
Incremental adjustments are somewhat intuitive (e.g. turning a
knob slightly lets you see the cutter or wheel move a similar
amount).
Even though a few models have 'automatic' clamping mechanisms,
grinding with them is a highly repetitive, mundane task. So, if
the additional capabilities are not required, an automated
grinder could be very attractive, and the TEMCo is the only
automated grinder currently offered in this price range.
Greater control or automated operation? Few people in these
threads have just one chainsaw: no reason why they can only have
one way to sharpen chains!
