V2.36 - Happy New Year

So, here we are at the end of another year. Wow… I always heard that the older one gets, the faster time flies. After studying that for a few years, I think I know why. When you’re 2 years old, 1 year is one half of your entire life. When you get older, 1 year is only one-50 something of your entire life. So time really doesn’t go faster, it just seems shorter. That’s my story and I’m stickin to it.

2012
The year that “they” say we’re gonna expire. There’s a Greek word for that – Baloney. I’ve read the last chapter of THE Book and some things it says must come to pass have not. It also says that Man does not know when the end will come, only the Father knows (Matt 24:36). So, come next Dec 22, we’ll still be here, although there may be fewer of us around. Now, having said that, I fully believe that we are well on our way towards the end. My clues are taken from the Holy Bible and some of the things it mentions are lining right up.
Years ago, no one could imagine that ‘the whole world’ could see anything at the same time (Rev 11:9). Now, it is not only possible, but routine.
We’ll get to the point that we can’t buy or sell anything without a certain mark (Rev 13:16-17) and even now, we can see the technology maturing to the point that this would not be impossible like it was years ago. You know, I’ve always thought that this might play out like this… Gov’t handout money is put on ‘smart cards’ and big momma gets to the register and says “I lost my card, but you gotta give me stuff anyway”. So the gov’t says, “Here, we have come up with a way to be sure you never lose it again. We’ll put this mark on your hand or forehead and all you need to do is put your number in front of the scanner and all is well.” So big momma says, “I’ll do it and the guy who come up with this idea is sooo smart. He needs to be President of the World”.

Oh yea, I’m probably wrong, but it IS coming. If you are still here when the “President of the World” shows up, do whatever you need to do, but do not take that mark. If you do, you will shut the door on any chance you’d ever have of seeing heaven. (Rev 14:9-11)

God Bless you all and we’ll see you in 2012.

V2.34 - Some Tools Defined

We’ve talked about some of these machines, so just in time for the holidays, here are some definitions for those who might be thinking about buying someone a tool for Christmas.

DRILL PRESS: A tall upright machine useful for suddenly snatching flat metal bar stock out of your hands so that it smacks you in the chest and flings your coke across the room, denting the freshly-painted project which you had carefully set in the corner where nothing could get to it.
BAND SAW: A large stationary power saw primarily used by most shops to cut good aluminum sheet into smaller pieces that more easily fit into the trash can after you cut on the inside of the line instead of the outside edge.
WIRE WHEEL: Cleans paint off bolts and then throws them somewhere under the workbench at the speed of light. Also removes fingerprints and hard-earned calluses from fingers in about the time it takes you to say, 'Oh, dang!'
TABLE SAW: A large stationary power tool commonly used to launch wood projectiles for testing wall integrity.
HAMMER: Originally employed as a weapon of war, the hammer nowadays is used as a kind of divining rod to locate the most expensive parts adjacent the object we are trying to hit. It is especially valuable at being able to find the EXACT location of the thumb or index finger of the other hand.
TWO-TON ENGINE HOIST: A tool for testing the maximum tensile strength of everything you forgot to disconnect.
SKIL SAW: A portable cutting tool used to make studs too short.
PLIERS: Used to round off bolt heads. Sometimes used in the creation of blood-blisters.
PHILLIPS SCREWDRIVER: Normally used to stab the vacuum seals under lids or for opening old-style paper-and-tin oil cans and splashing oil on your shirt; but can also be used, as the name implies, to strip out Phillips screw heads.
STRAIGHT SCREWDRIVER: A tool for opening paint cans. Sometimes used to convert common slotted screws into non-removable screws and butchering your palms.
HYDRAULIC FLOOR JACK: Used for lowering an automobile to the ground after you have installed your new brake shoes , trapping the jack handle firmly under the bumper.

Yes, these tool definitions are a bit ‘tongue-in-cheek’, but the underlying theme heads right back to: Be SAFE, not sorry.

V2.33 - Rusty tools? What to do.

We got a good question from Donald in Arlington, TN for this week (my, does our paper get around or what?). Donald says: “I don’t use my woodworking machines a lot, but when I do try to use them, they have a coat of rust on the tables. How do I stop that?” Hint: the more you use your tools, the less rust will be able to grow on them.

While I am tempted to just answer Donald’s question, I think you all might be better served by knowing what to do when you find the rust, then we can learn how to prevent it. First off is to clean the rust from the surface. How to do that really depends on how severe the rust is. For this column we’ll just deal with light surface rust. You can use fine or medium size steel wool, or a palm sander with 220 or 400 grit paper, or even wet or dry sandpaper and sand the rust off. My favorite method is to use a sanding block with 220 grit ‘wet or dry’ sandpaper and sprinkle a bit of nail polish remover (acetone) on the table and use that as the paper’s lubricant. Sand the whole table and then wipe the surface thoroughly with clean rags soaked in acetone. Once the surface is clean, dry the area very good…because now comes the ‘How do I stop that?’ part.

The ‘old school’ method is to coat a good rust-free surface with Johnsons paste floor wax and lightly buff it. Don’t remove all the wax, just try to make the coat spread evenly. The modern ‘hip’ method is to use a product called Boeshield T-9® (you can find it at Sears) and follow the directions on the package. CAUTION: Do NOT use automotive wax. Most of them have a high water content and will actually cause the rust you are trying to prevent.

On woodworking tool surfaces Boeshield T-9® recently topped all other surface treatments in Wood Magazine's article on “Rust Busters”.
The formulation is based on a unique combination of solvents and waxes and is designed to penetrate metal pores and dissolve minor corrosion, then leave a resilient waxy coating that lasts for many months.

During my years in Technical Service on woodworking machinery, we consistently recommended the paste floor wax and our customers had great success using it. It’s like a ‘tried and true’ method for preventing surface rust. Fortunately, I’ve heard so many good things about Boeshield T-9® that I am confident in that, also. Thanks for your question, Donald.

V2.32 - Safety - it’s what’s for dinner

Let’s shift gears a bit this week and introduce a subject that should be near and dear to all of us - Safety. Specifically- Personal Safety in the shop. This came to my mind because of the article I did about using safety belts.

Safety is one of the basic building blocks in any shop. In fact, safety is something that we all need to be aware of in every aspect of our everyday life. Without a constant mind-set of being concerned with your own safety, you might tend to drive without using your seat belt. Without this constant awareness, you might cross the street without looking both ways. Safe thinking is something that we all need to keep on our mind.

This is especially true in the woodshop. If you ask an experienced woodworker what their most prized possession is, many of them will proudly hold up a full set of 8 fingers and two thumbs. These are the woodworkers who have been safety conscious for a long time, yet many of them will also tell you stories of how they have been very fortunate in certain situations to have escaped serious injury due to their own lapse in judgment. Many of the stories one hears of “being lucky” start out with, “Well, I was in a hurry and thought I could just do this one thing quickly…and I almost didn’t get away with it. It was really stupid on my part.”
Remember, the best safety device that you have access to is your own good sense. If something you are doing creates hackles on the back of your neck, it just might be your intuition telling you to stop before you get hurt. Don’t get in a hurry. Think through your actions first and be prepared to work safely.

You should never work on, or operate, woodshop machines if you are taking medication that makes you drowsy, if you are very tired or if you are under the influence of alcohol. These substances may cause you to ignore potential safety hazards. You should always use proper safety equipment. Eye protection is first and foremost on any safety equipment list. It should comply with the American National Standards Institute (ANSI) Z87.1 standard. Hearing protection is also important and it should comply with the ANSI S3.19 standard. Even if you install the best dust collection system that money can buy, it is always wise to use a proper dust mask. Many people use the white disposable paper masks; however, those type masks typically allow too many smaller particles to pass thru them. I recommend using a good respirator mask that has replaceable cartridges. In extreme dust environments, there are other respirators that supply fresh air to an attached hood.

V2.31 - What a ‘shocking’ development

With winter coming on, and it being the time of the year with very low humidity, I’m thinking it’s time to talk about the stuff that makes us jump out of our skin. Static electricity in your woodshop. I’m sure we’ve all experienced it when using our belt sanders. You’re just sanding along, minding your own business, and then your finger gets too close to the table and POW, all of a sudden you think your wife snuck into the shop and zapped you with her Taser. But no, it was just your ‘friend’ Static Electricity. It can show up on all rotating equipment and especially in your dust collector ducts.

Static electricity in a wood shop is mainly caused by two things. First is low humidity in the air. Static is especially troublesome in winter when the outside temperatures are low. A rule of thumb is the colder it is outside, the lower the humidity is inside a heated shop. As a result, static charge builds up easily and causes shocks when the electricity discharges through contact. The problem is even worse if a shop’s dust collection system exhausts its air outside the building. This builds an additional requirement for fresh air coming in and the fresh, cold air will have low humidity once it has been heated indoors.

The second thing that causes the static electricity problem is motion between two things. In the case of a belt sander, it is the motion between the belt, platen and pulleys that causes the build-up of electricity. In the case of the dust collector or Shop-Vac, it is the motion of the particles through the hose. There are two places where the charge can build up. One is in the machine the dust collector is attached to and the other is on the person who is operating it. Fortunately, grounding the frame of the machine will eliminate the buildup of the static charge. All fixed machinery, such as a table saw, jointer, planer etc., should have its frame grounded to a water pipe or at the very least, to the ground conductor or conduit sheath of the machine’s electrical wiring. Sometimes this is not possible, especially if the machine is electrically double insulated, as is the Shop-Vac.

Beyond grounding the machine, the best cure for static problems is to try to keep the humidity in the shop from getting too low. This can be done by using bag-type dust collectors that re-circulate the same air within the shop after the dust has been removed. These collectors will also reduce your heating bill. Other ways of adding moisture to the air, such as using humidifiers, are worth considering. Another thing you can do is wear shoes that bleed off the static charge rather than allowing it to build up.

V2.30 - Bench Grinder: Tips & Techniques

Ok, back to farm…We’ll finish up our look at Bench Grinders with a few Tips & Techniques. Every once in a while, we run across something new about Bench Grinders, but most of our knowledge is tried & true, and time-tested.

First off, every ‘store-bought’ grinding wheel that I know of has blotters on its sides. ‘Blotters’ are those pieces of paper, or cardboard, on each side of the wheel. While they might look like just a convenient place for the manufacturer to put warnings and such, they actually do serve a very critical purpose. When a wheel is put on a grinder, there are metal flanges that squeeze against the sides of the wheel. If the wheel had no blotters, those flanges would be tightening up against the actual rock of the wheel and you would stand a very good chance of cracking the wheel. Blotters provide a ‘buffer zone’ between the flanges and the wheel rock and thereby cushion and distribute the tightening force. Bottom line: Don’t buy a wheel that has no blotters or, if you do, don’t put it on your grinder without making some blotters and using them.

While we’re talking about blotters, they have another use. Most manufacturers put their product warnings on them and one of the major warnings is “Do not grind on side of wheel”. Now, do most of us follow this warning? Probably not, but I am here to tell you that if enough sideways force is applied to as grinding wheel, a wheel explosion is a very real possibility. Years ago, I saw a training film (yes, “film”- not tape or DVD- I’m dating myself) wherein a grinding wheel explosion was created and it is not a pretty sight. Even though I might use the side of the wheel to do some very light & delicate, precise grinding, I’m only able to do so because of my many years of experience with this and I know that I am not applying any sideways force at all. My general advice to everyone is: Don’t grind on the side of the wheel.

Lastly, always keep the tool rest adjusted as close to the wheel as possible, in order to provide the most support for what you are grinding on. Use your safety glasses. Keep the grinder’s eyeshield in place to provide added protection. Make sure the spark arrester is in place and adjusted to within 1/8” of the wheel and always keep an open container of water handy for cooling off your material. If your grinder has a factory water pot, that’s even better. Keep it full.

These hints, and our previous bench grinder columns, should help you get the most out of your Bench Grinder. Happy Grinding!

V2.29 - Seat Belts – buckle up, please

If you’ve spent any of your precious time reading these little articles of mine, then you’re probably aware that I’m known to go off on a tangent at times. Welcome to the latest one.
We recently had another youngster die because she was not wearing her seatbelt and got ejected from her car in a vehicle accident. I’ve seen reports that ‘she was doing everything correct- not speeding, not drinking, etc’, but when she chose to drive without her seat belt buckled, she was putting her life at risk when this just did not have to be. Please understand, I am not ‘piling on’ and saying she caused her death. I have nothing but compassion for her friend and relatives. I am so sorry that they have to go thru this, but people, if you don’t want your folks to possibly go thru this - buckle your dad-burn seat belt.
How anyone can drive a car without fastening their seat belt is beyond my understanding…but it was not always this way. I used to drive cars that did not even HAVE seatbelts. (Please note that I have installed seat belts on all 3 of my antique cars. I will not drive without them) I can remember driving my 1950 Ford all over the country without it even having a seatbelt. It does now.
My ‘moment of realization’ came in 1990. I had been driving my dirt stock car for 3 seasons by then and wouldn’t even THINK of racing without wearing my 5-point harness. (On the side note, I wonder why all racecars have shoulder harnesses and lap belts? Perhaps because it can save the life of the driver in an accident?... well DUH) So, here I was driving down the interstate in Memphis, TN on my way to work in my 1982 Chevette (yes, I had one - don’t laugh) no seatbelt on and it was raining cats & dogs. Well, all of a sudden, I started hydroplaning and the car began to slide sideways on the road. Fortunately, there were no other cars close to me and I just let off the gas pedal and when the car slowed down enough, I got traction back. Well, I got to thinking, ‘what if I had slid far enough to slam into the guard rail? Most likely, I would have been thrown across the car and would not have even been behind the wheel any longer. You can’t drive if you are not behind the steering wheel.’ Those were my thoughts…and I immediately buckled my seat belt and have not driven a car without doing so since.
My point is, why risk your life if you don’t have to? EVERY time you get out on the public road, something my happen to you. They are called ‘accidents’ for a reason – no one plans them. PLEASE buckle your seat belts and live to tell about it.
