Cleaning up an old table saw

Why a one-time happening would become his rule is another oddity.

Yes, It was Ruskin. ;~) I recall seeing all of that on water on the BS on the right hand side of the garage as I was walking out.

It had been warm and humid all day...till we were wrapping up and the front blew in.

IIRC I found the HTC covers and the great chop saw stand that you bought after I saw that issue. ;~)

I know it does not make any sense.

Go here and hang out and look through the posts.....

Craftsman restores and scores of others...

Sign up and lurk around for a while to see what's up.

Go here:

and do some more reading.....

For the top, I would use single edge razor blades after a good soak in WD40. Use a basic razor blade scraper to "shave" the rust and other gunk up. After several rounds of that, use a ROS with

120,220,440 and WD40 to clean it up.

To get it really shiny, use any good polishing compound and a buffer.

A few hours of work and she will come back to life...

Look at some of these:

http://www.v> There's an old Craftsman table saw in the basement of the building my Dad had

his office in. It's probably 30 years old, and never saw much use. I'm trying to fix it up a bit to use it on occasion.

the nice folks here for some advice.

"bubbling". The "wings", if that's the right term were more badly rusted around the edges, which had been bare metal.

came out passably well, I think. The wing edges still look rusty, but I flattened them down enough, I think.

ago, before I did any brushing. So now I have a slurry of rust particles and WD-40 covering the table top. I could use some sort of degreaser to get it off, but then I imagine I'd need to cover it with something to keep it from rusting again. Wax, I'm thinking.

I worded it so poorly. I forget sometime that these groups are international and sarcasm does not translate well from one language to the other, sometimes not even from American to British.

This was a comment on a previous post about graduating from school.

Self esteem = "having a good opinion of yourself"

Many schools and teachers in America feel that it is more important for the student to have a good opinion of themselves than to know subjects like Math, history, language, etc.

Hence they pass students on to the next grade when they have not learned the subjects in their current grade. (Should have failed and been required to retake the courses.) In these cases even though they graduate from high school or college, the only thing they have when they graduate is that they think highly of themselves but have no knowledge of the subject matter they were suppose to have learned.

That is ice tea. Remember there are those on this newsgroup that drink tea hot.

Are you brother? This is starting to sound like one that I had with my brothers about events in our past.

[Swingman]

Worse than that.

According to our wives, our brains, if nothing else, are cloned identical twins. :)

What do their beliefs have to do with their theories? I hope you're not one of those who sees no difference.

I hope that I am right in thinking that that is being reconsidered. We're not doing kids a favor promoting them if they did not master the essence at least of the material taught them. I know there is more reliance on summertime remedial classes, and that some schools do not promote. (it is not always the teacher nor always the kid that is the problem).

You can have heated debates between scientists who both are very convinced they are right, and at first glance from their arguments they both are right, but, wait, that can't be ... So the problem becomes who made a mistake in reasoning, or viewpoint, or observation. It sometimes isn't easy to see at all. And that leaves out those arguments that are indeed based on flawed basic points, which there are too.

"Quite warm" was likely pretty humid too. The cold front dropped the temp of the air which cooled the steel, and the absolute humidity (mg of water per cubic meter, or oz per cubic yard) stayed the same - raising the relative humidity - and the dew point and surface temperature met. The relative humidity of the cold air was likely 90+ %. If you had simply cooled the metal quickly to the same temperature, without changing the air temp, you would most likely also have experienced the condensation or "sweating" of the metal.

[clare]

No moving required Han. Say it was 30C and 55% humidity. and the cold front dropped the air temp to 20C. The relative humidity would be 102%

If it's 90F and 55% RH, anything cooler than 71F will get wet. If it's 30C and 55% RH, anything cooler than 19.96C will get wet.

Reduce the RH to 50% and it happens at 18.42C

More likely the garage was open, the cold front hit, and they pulled the garage door down. The cold damp air cooled the metal and the now "supersaturated" air condensed out on the cool surface. See previous post re: RH and dew point.

You guys down there in (central?) Florida have a lot of high humidity

-We get it up here in Central Ontario for a couple of weeks a year - and I experienced it a LOT when I was in Zambia. Didn't know you COULD have RH over 100% - but under certain conditions it happens - it's not raining, or even really "misty" but swing anything through the air at any speed and it gets wet (instead of drying off). A drop in temperature and everything in the shop got wet - particularly if a slight breeze and the shade of the roof kept the inside shop temp just below the outside air temperature (Thermal mass of concrete shop cooled off over-night and sun on the ground in the yard heated the air above - nothing to have air temp out in the yard

46C, (115F) and the shop a relatively comfortable 35C (95F) or even cooler, then have the clouds and breeze move in and the outside temperture drop a few degrees.

With Victoria Falls, the worlds largest humidifier 10 Km down the road, October was HELL. The humidity was aproaching 100%, and you KNEW it wasn't going to rain for another 6 weeks!!!

But seldom from a glass- - - - - -

[Leon]

Close but the door stayed open when this all happened.

[Leon]

Very humid it was! Sounds like you may have the answer here.

[Leon]

The RH was probably closer to 80~90%, common in Houston. And we probably saw a 20 degree temp drop in 10~15 minutes.

[Leon]

I believe you have also witnessed the situation!

[Keith Nuttle]

Relative humidifies over 100% are possible, and can happen with quick change in temperatures. They can also happen when there is nothing to cause the formation of the precipitant,(condensation).

Supersaturation is use a lot in the chemical industry when the product requires a precipitation of purify the product. In some incidences the supersaturation is produced by boiling, either at room temperature, to reduce the volume and increase the concentration of the material.
