Column #47 - Toodle-oo to 2010

So long, 2010, 2011 is upon us. Back in 1985, I could not even conceive of still being around in 2011, but here we almost are.

Sitting here trying to think up something cool to say for the New Year is coming close to leaving me fingerless (which is the same thing as ‘speechless’, if I were a radio talk show host). I know we were in the middle of talking about Industrial Planers but Christmas, and then New Years, only comes around once a year. So, here I sit.

One thing I would like to know for next year is: What do YOU need to know about? I really have no idea how many people may be reading these columns, but whoever you may be, on my best day this column is for you.
Do you have tools? Is there something wrong that you may be wondering about? Ask Me. It’s what I did for over 25 years and I’m doggone good at it.

I’m also pretty good at making people laugh, so I thought I’d close out the year with a short story: A man is flying in a hot air balloon and realizes he is lost. He reduces height and spots a man down below. He lowers the balloon further and shouts: "Excuse me, can you help me? I promised my friend I would meet him half an hour ago, but I don't know where I am." The man below says: "Yes. You are in a hot air balloon, hovering approximately 30 feet above this field. You are between 40 and 42 degrees N. latitude, and between 58 and 60 degrees W. longitude." "You must be an engineer," says the balloonist. "I am," replies the man. "How did you know?" "Well," says the balloonist, "everything you have told me is technically correct, but I have no idea what to make of your information, and the fact is I am still lost."
The man below says "You must be a manager."
"I am," replies the balloonist, "but how did you know?"
"Well," says the man, "you don't know where you are, or where you are going. You have made a promise which you have no idea how to keep, and you expect me to solve your problem. The fact is you are in the exact same position you were in before we met, but now it is somehow my fault."

Enjoy the New Years holiday weekend, may Our Lord Jesus Bless you all - send me your comments - and we’ll see you next year.

Column #46 - The True Reason for the Season

“Happy Holidays”…what? Uh…”Happy Holydays”? Well, that’s a little better. How about “MERRY CHRISTMAS”??? It really frosts my pumpkin to hear happy holidays. Sure some say that this time of year was a pagan holiday long before Christmas- so what? It isn’t now, and hasn’t been for hundreds of years.

Christmas 2010 is here this weekend. We hustle, we bustle and we shop until we drop. Sadly, so many of us seem to ignore the true reason for the celebration. The birth of Our Lord Jesus. My pastor has some good thoughts about the commercialization of Christmas. If I remember correctly, he says that it is really a cool deal when everyone, no matter HOW they do it, is celebrating Jesus’ birth. I must agree.

For this weekend’s column, I could find no more appropriate words than these: “Now the birth of Jesus Christ was as follows: After His mother Mary was betrothed to Joseph, before they came together, she was found with child of the Holy Spirit. Then Joseph her husband, being a just man, and not wanting to make her a public example, was minded to put her away secretly. But while he thought about these things, behold, an angel of the Lord appeared to him in a dream, saying, “Joseph, son of David, do not be afraid to take to you Mary your wife, for that which is conceived in her is of the Holy Spirit. And she will bring forth a Son, and you shall call His name JESUS, for He will save His people from their sins.” So all this was done that it might be fulfilled which was spoken by the Lord through the prophet, saying: “Behold, the virgin shall be with child, and bear a Son, and they shall call His name Immanuel,” which is translated, “God with us.” Then Joseph, being aroused from sleep, did as the angel of the Lord commanded him and took to him his wife, and did not know her till she had brought forth her firstborn Son. And he called His name JESUS.” (NKJV)

The words are there and we read them… but do they sink in? God’s Son was born… not in a palace, but in a barn. We love barns in Tennessee, but would we want our kids to be born there? Little Jesus, Son of the Most High God…in a cradle. It strains our imagination, but the written record is there. All we need do is believe.

Merry Christmas to all and May God Bless us - everyone.

Column #45 - The continuing saga of snipe

As I had said a week or two ago, I am still a rookie at the newspaper column business and it reared its head in my column from last week.

There was a very important paragraph that got mangled up because I used odd characters. Here is what came out… “In other words, if you need a _” thick piece, take your adjustment to 1” and bring it down to _. Do not start at _” and go up to _ and then plane it. If you do that, you are leaving the backlash in the lead screws & nuts and that will be increasing your chance of snipe.”

As you can see, the dimensions I was referencing got obliterated. I thought I had best rewrite the paragraph so that my meaning is crystal clear. Here is what I meant to say. ”In other words, if you need a Three-Quarter-Inch thick piece, take your adjustment to One-Inch and bring it down to Three-Quarter-Inch. Do not start at One-Half-Inch and go up to Three-Quarter-Inch and then plane it. If you do that, you are leaving the backlash in the lead screws & nuts and that will be increasing your chance of snipe.” Hopefully, you can see the difference and why it is important.

Alright on to new business - the Industrial Planer. Most Industrial Planers have bed rollers and they are height-adjustable. Ideally, bed rollers are for use when you are planning very rough or warped boards. Yes, planning warped boards is not a good idea; however, in certain instances (like sawmills) one needs to make a pass through a planer and then go on to other machines. In most IP’s, the bed rollers are directly underneath the infeed rollers. This helps put the ‘squeeze’ on the stock as its going through the planer. As I said, the bed rollers are usually height-adjustable and very rough boards can use a bed roller height at 5 to 10 thousandths. If one is trying to get a snipe-free surface, the height of the bed rollers should be level with the bed or even 1 to 2 thousandths below the bed. If a smooth surface is the objective, having the bed rollers above the surface of the bed can actually create snipe because of the upward force of the board as it bumps up onto the bed roller.

Yes, there are many issues with an Industrial Planer, and it’s gonna take quite a few columns to work through them. I’ve got time, do you?
See ya next weekl

Column #44 - Our ‘snipe hunt’ continues.

Last week, I gave you the most basic description of what snipe is and how it happens. The “why” it happens and how to minimize it, is the subject of this week’s column.

Setting the stage, your lunchbox planer has a movable head for depth of cut. It has no bed rollers, and the distance between the infeed roller and the outfeed roller is 4 inches. With that foundation, our snipe would be 2” long at the front and 2” long at the rear of the board. “Why” do you ask? Good question.

Here’s why- as long as the board is underneath both rollers, the head will be shoved upward by the force of the rollers pushing down against the board.
The early lunchbox planer designs were notorious for the problem of snipe. Later designs, and the ones most often found now, had a head locking mechanism made into the planer that allowed the operator to actually lock the head in place, which has pretty much eliminated snipeing on this design.

One thing that will do much to decrease your snipeing is [on the movable head style] to ALWAYS make your final depth of cut setting by moving the head downward. If you will do this, it will remove the backlash out of the lead screws [the threaded rods that the planer head moves up and down on] and their nuts. In other words, if you need a ¾” thick piece, take your adjustment to 1” and bring it down to ¾. Do not start at ½” and go up to ¾ and then plane it. If you do that, you are leaving the backlash in the lead screws & nuts and that will be increasing your chance of snipe.

On the early design lunchboxes, there were many different methods attempted to eliminate snipe. Some were easy, some were weird and most did not work every time. Once the planer makers figured out that customers were not in the mood to accept snipe as a way of life, they went back to the drawing board and did something about it. Hence, the head lock I mentioned earlier.

So far, we’ve been talking only about the lunchbox planers. Let me tell you straight up, snipe on industrial planers is a real happening, too. The Industrial planers have an inherent advantage because most of them have a movable bed, not head. This design difference makes snipe a lot easier to control, but there are so many adjustments that other things can go wrong. We’ll ‘go there’ next time.

Column #43 - Yes, a ‘snipe hunt’ is a real thing.

It’s Thanksgiving weekend as I write this and since I am new to the art of writing a weekly column- well, yea, I’ve done a few, but this is my first Holiday season- I am just learning that I should be a week ahead if I want my column to seem ‘on time’. Point being, I should have used last week’s column to wish everyone Happy Thanksgiving! Now, by the time you read this, T-day will have been gone for a week. Anyway, I’ll get better and more timely as I learn.

This week I’d like to introduce you to one of the most frequent problems of a planer. Snipe. Yes, it really IS called that…among other things. The basic symptom is that after the board has been run through the planer, the thickness of the ends is thinner than the middle of the board. Remembering that the purpose of a planer is to make the board the same thickness in all areas, Snipe is not an acceptable outcome.

Snipe can also be known as ‘cut out’; ‘dip out’; ‘notching’- names like that.
Essentially tho, one looks at the board surface and sees where, for the first few inches and usually the last few inches, the knives have made a deeper cut than they do on the rest of the board. For the purpose of our discussion, we’re going to limit ourselves to lunchbox planers that do not have bed rollers. [Bed rollers, which are mostly found on industrial planers. create other situations that we aren’t ready to talk about].

Alright, so you’ve sent a board thru and you see and feel snipe on the ends of the board. The first thing to realize is that this is being caused by the head of the planer rising as the board gets underneath both feed rollers. Again, we’re talking about lunchbox planers that usually are pretty simple- they have a fixed bed and a movable head. The head moves up and down to adjust the thickness of the cut.

So what happens- as the board is placed on the bed and pushed into the planer, the infeed roller grabs it and pulls it in, about 2 inches into the planer, the board runs underneath the knives and starts being cut. About 2 inches after that, the board runs underneath the outfeed roller and starts being pulled by both rollers, AND this is where the snipe stops… on the front end of the board. As it comes out, it leaves the infeed roller and snipe starts on the trailing end of the board. In this case you would have a 2” snipe on each end of the board.

Lots of background I know, but knowing the basics is essential to knowing why snipe occurs and what to do about it.
