Further A's to Q's
First
up this time out, we have a few additional comments on questions
featured in the Q&A section of last issue's eZine.
For
instance, here's a reader who had a similar situation to the
questioner with a "rumbling table saw." - Editor
"I
have experienced a similar condition with a Craftsman saw using a
Freud Fusion full-kerf blade. When the centrifugal switch on the
motor closes on deceleration, the motor provides a breaking action
and the blade flexes or wobbles and enlarges the ZCI slot. I
purchased the blade when they first became available and exchanged it
about a year later when the Freud demo truck was here. The second
blade behaves better during deceleration with less wobble. The second
blade has a clear material in the expansion slots that may dampen the
vibration characteristics. I have about a dozen different blades
(five other Freud blade models), and the Fusion is the only blade
that seems to exhibit this characteristic. The saw always emits the
rumbling sound on deceleration." - Joe Kaufman
Plus,
some additional suggestions from a fellow scroll sawyer to the
questioner who asked in eZine 288, "Will Ballast Dampen Scroll
Saw's Vibration?" - Editor
"I
am an avid scroller and have a lot of fun making and selling my
products. Over the years, what I have found in regard to vibration is
that the solution to eliminating it is in direct relation to the saw
itself. I started with a relatively inexpensive scroll saw, which was
given to me as a gift in the 1990s. When run, it would shake like a
cat in a dog pound. Nothing that I would do could eliminate that
vibration. As I progressed in the craft and sought out advice and
tips from other scrollers, publications, and blogs, I found that
replacement of the old saw with one of better quality was the only
solution. When I bought my Dewalt 788 (note: there are several other
brands of excellent saws out there as well), all the vibration, as
well as all other existing problems, vanished. So, the answer to your
question is that you may be able to reduce the vibration a little bit
by using various methods, but to achieve what you seek in having a
saw that is a pleasure to use you are going to have to upgrade. Thus
another affirmation of the old phrase, "You only get what you
pay for." Happy scrolling, Ralph. I hope this has been of help
to you." - Jim Tanner
Table
Saw Rules - You Tell It
And,
of course, readers had a lot to say about the U.S. Consumer Products
Safety Commission's proposed rules regarding table saw safety when it
comes to blade contact. We're always glad to hear from you, but we do
want to remind you that, if you want your comments to be considered
by the CPSC as they solicit public input before their decision, you
do need to send your comments directly to them, either through the
website www.regulations.gov, or via the physical address provided in
Rob's editorial in eZine 288. Deadline for your comments to reach the
CPSC is Dec. 12, 2011. - Editor
"I
shared the following comments with the CPSC: We have enough
regulations protecting us from ourselves. How about my planer, my
router, my miter saw my skill saw, my jointer, my lathe or even my
drill press? Does this mean that every time somebody invents a device
to instantly stop (damage) a machine when its cutting edge or moving
parts touch or even gets close to any part of the anatomy that you
guys are going to mandate that manufacturers spend millions
redesigning tools to incorporate them? You could easily make
purchasing these machines unaffordable for the average woodworker.
What's next? An electric carving knife for my kitchen that instantly
stops if I get distracted and try to run it through my finger ?
Accidents happen. Always have and always will. And they are usually a
result of inattention, lack of training,modification or removal of
existing safety devices or just plain bad luck rather than lack of a
government regulation protecting us." - Chip Conklin
"Thank
you for bringing this proposed rule from the CPSC on table saw safety
to your readers' attention. I have submitted an extensive opinion to
the CPSC outlining my objection to making SawStop (or other similar
devices) a mandatory requirement for table saws. I am familiar with
the device, and it is certainly an interesting safety development,
but not without considerable flaws of its own. I also know that
SawStop has had limited success on the open market due to a number of
reasons and that they (as the petitioner to the CPSC for a mandatory
requirement) would almost exclusively benefit financially. Thanks
for the heads-up." - Rudy Landry
"I
thoroughly enjoy every issue of Woodworker’s
Journal and
the Woodworker's Journal eZine. I am responding to your recent
editorial, received online. I’m too old (69), tired and crotchety
to follow all those confusing links to send comments to the idiots on
the Consumer Product Safety Commission. (Five
copies, indeed! And they won’t read any of them, anyway.) Please
tell them for me that I want them to stay the H---
out of my shop; out of the toolmakers’ factories and my friendly
retail tool supply stores, too! When I was six years old and
'helping' my dad in his shop, the first thing he said to me (as
well as I can recall, 63 years later) was,
'Don’t touch that!' For as long as I can remember, neither my dad,
myself or my grandchildren have ever forgotten Dad’s admonition
…And we all remain intact as a result.
"I
daresay that getting warnings, labels and directions foisted on us by
government bureaucrats will not
be likely to have any desired effect on us consumers. If we are so
bloomin’ stupid and careless as to make physical contact with a
spinning blade, then all the CPSC’s angst and the resulting extra
dollars added to the cost of our new Craftsman 10-inch table saw is
not
likely to prevent our doing just that – and losing fingers in the
process. They should pay more attention to putting annoying labels on
our passenger-side rear-view mirrors, such as 'Objects in mirror are
closer than they appear.' No! Really?! And here I thought that I had
just developed a miraculously improved sense of sight!
"At
my advanced age, I hardly think I need a bureaucracy such as the CPSC
to watchdog me in an effort to make sure I don’t fall prey to my
own stupidity and negligence and forget the safety rules I have
successfully practiced for all these years! They should all be given
a Dymo label-maker and go around and stick warnings all over their
own
dang stuff, if it would make them leave the rest of us alone. The
last thing I need cluttering up my shop is some government watchdog,
warning me, 'Don’t touch that!'" - Rod Eisenbise
"'Talking'
to OSHA [Occupational Safety and Health Administration] or the CPSC
is like talking to a wall. I am a retired woodshop teacher. I taught
for 19 years in five high schools, in two school districts. Safety
was my main concern, six periods a day, five days a week. And I
harped on it until students were 'sick' of hearing it. Then I did it
some more. I'm proud to say, that on the table saw, I only saw two
injuries in all that time. One was an avulsion of the tip of a thumb.
The other was a laceration of the area between the thumb and the
index finger, on the TOP SIDE of the hand. It was a 'freak' accident
in which the student also repeated fault several times without
prompting. He turned his hand over and it came in touch with the
spinning blade. He 'knew it was going to happen, but was powerless to
stop it.' It required 10 sutures to close.Without any prompting from
anyone, the first admitted thathe was working faster than he should
have. All safety guards were in place. A neurosurgeon at the County
Hospital of Los Angeles tried to reattach the avulsed part; but it
was too badly mangled.Both injuries did heal during the remainder of
the semester. No injury caused any inconvenience to the student
though to graduation or employment, beyond that.
"Considering
my experience, I have developed some strong opinions about the table
saw. You might think that I would be in favor of installing every
available safety device on the market. That is false. In fact, quite
the opposite is true. On my own computerized, Craftsman table saw, I
have removed the guard because I can't see the work though the
plastic. I can't use it anyway, because of my use of a dado blade to
run rabbets. Removing the guard also removed the splitter. However, I
retrofitted a splitter, because of the number of times that I have
used a screwdriver to keep the blade from binding. I stand to the
side, out of line with the blade to avoid the occasional kickback. A
kickback claw only prevents me from withdrawing the stock back, to
rip it from the other end. I don't use a run-out table, because I'm
limited in room. When I need space for a long piece of ripped stock,
I wheel the saw outside the garage. I have rigged lots of light out
there for night work. I do use a push stick. In fact, I may use two
at a time depending on the width of the stock. I have no hold-down
devices and would not install one.All other safety rules are applied,
i.e., eye protection, no loose clothes, mitigating toxic dust of
certain woods, hearing protecting, etc." - Steve Green
