A tip for lubricating you clamps.

For many years I have had clamps that began to perform poorly.
I learned by experience and through the advise of the manufacturers of
how to over come the problems.

My wooden double handle screw clamps would loosen on their own. I would
tighten both handles and could immediately watch the handles turn and
loosen.

The solution, provided by Jorgenson, use a stiff wire brush to
thoroughly clean the threads of the screws. Problem Solved.

Another issue that I learned to remedy by myself was that which affected
my Bessy K-body style, Cabinet Master K-body clone, and fresh out of the
box Jet K-body clone bar clamps.


The symptom. It seemed that when tightening the clamp handles that
there was no lubrication. The motion felt dry and I felt that the screw
was providing more resistance than the actual material that I was
clamping. I will restate for clarity that all 6 of my Jet clamps felt
this way straight out of the box.
The Cabinet Masters over several years developed this feel as did the
Bessy clamps. Oh, and so did my aluminum bar clamps with the butter fly
style screw handles.

For years I cleaned the threads and sprayed a dry lube on the screw with
very mixed results with most results being only slightly better.

Jorgensons answer and solution was to send me a free replacement screw
head. That worked for a few years but......

Then through divine intervention the fix/answer came to me.

If any of you have witnessed this problem with any of your screw clamps
this may be your fix.

I discovered that there is truly friction and resistance in tightening
the clamp. As mentioned above it would seem obvious to clean and
lubricate the threads of the screw.

I discovered one more spot to lubricate and doing so immediately made
all of my brands of clamps operate closer to silky smooth than prior to
locating his spot.

Starting to sound like one of those commercials, huh?


On most all of these K-body style clamps and the clones the part you
need to apply oil is partially hidden and out of site.

You also need to oil the end of the screw where it is riveted onto the
steel washer that delivers all of the clamping force. There is
tremendous friction at that connection and a drop or two of oil
instantly decreases the effort needed to tighten the clamp.

Unnoticed being the key word. Or possibly the clamps are not being used

The cleaner component that causes problems is carbon tetrachloride/perchlorethylene/methylene chloride and such.
Those are VOLATILE compounds, with warnings to only use with good ventilation,
and a day after applying them, they aren't on the apparatus.

You should also only weld with good ventilation. Ozone is nasty, too. And NO2, and so on.

I believe tetrachloroethylene and know methylene chloride are the key
ingredients in plastic welding solvents. It's not just welding you need to
keep them away from, but many plastics.

One of my favorite glue clamps is a piece of 2x6. A one foot section
of steel, 2" by 6" cross section, weighs about 40 lbs. It's very low maintenance,
and in conjunction with some polyethylene foam, clamps even irregular surfaces effectively.

I recall the quote going more like this.

That no good nasty sucker is about the out-smarting'est man that I have
ever seen. I will never save up to buy any product of this
in-vent-er/future government hot shot.
We are loose'n our rights to make emotional buying choices about our
saw's.
So I am not stubbern enough not mention about cutting myself with my TS,
hell I'm right here typing. I'll admit it, it was my fault, not the
saws fault. So there is no reason to blame the saw cause it was not a SS.

Guys! since this accident was not really an accident, what could I have
done differently to have prevented this.

Leon: SawStop.

Back to number 4

Finger looked like hamburger and hurt like hell.

5. What kind of saw was it?
6. Wasn't a SawStop.
7. If you multiply pi times the measurement across the blade and do
some other calculations you end up with a number.
8. I like pie

Once caution about carb cleaner. or brake cleaner.
if you weld, never use either.
if there is any trace of liquid (doubtful long term) but still a
possibility hitting the liquid with intense heat as a welder could
leave you paralyzed or dead. it can cause nerve damage.

After reading about that, I no longer use it, as I do weld. I don't
clean anything that I might use during welding with those cleaners.

The first time I read about this, three or four years ago, I thought "yeah, riiiiight". Checked
into it, though, and it's a *very real* hazard -- the result is one of the gases that was used in
chem warfare in WW One. Phosgene, I think. Anyway, it's a *nasty* bastard.

Ok, let me post this.
Unfortunately OSHA had the info, but it's now been pulled.

I use carburetor cleaner to keep my clamps working properly. The
Carburetor cleaner has to beneficial properties. It being basically a
light oil, keep the tool from rusting. Most importantly is is also a
solvent that will remove the glue that always gets in the threads of my
clamps. The clamps I use most are the perimeter clamps that I use to
make picture frames.

I don't weld, but occasionally burn the piece of wood that I am cutting
on my table saw ;-)


Even if the cleaner you use contains a clorohydrocarbon, it would take a
lot more that a trace on the material you are welding to cause any
problem, including health problems like the ones you mentioned. The
OSHA limits for exposure of an 8 hour period for from the attached MSDS
sheet is less 125 mg/cubic meter

That being said because of the organic materials in the cleaner, it
could be a flammability problem if you use a very large amount and then
start welding, as you could have created an explosive mixture.

This is an example of a c cleaner that contains a clorohydrocarbon.

Personally I use a cheaper on called Supertech from Walmart

As I indicated in my original post where I posted the MSGS sheet, not
all brake cleaners on carburator cleaners are created equal. I posted a
cleaner based on Methylene Chloride. You posted a brake cleaner that
contains tetraChloroethylene. The one I use Supertech contains
Acetone, Toluene, and Methanol and no chlorohydrocarbons. While they
are all flamable, and volatile, they are completely different materials
in the health hazards, and must be treated differently.

Amen!

I have/had the same problem, thought the threads were galling in the
clamp. Grease helped but not as much as I had hoped.

A few drops of oil with a swamp cooler oiler did the trick. The oilers
long plastic tube reaches to the area where the ball of the screw enters
into the "foot".
