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
