Laser engraving is an art and a science. It requires a special laser engraving machine. Not all laser machines can properly engrave on anodized aluminum. Even if you have the right machine, you need to:
Try engraving some test pieces to find the right voltage
The right number of passes
The right position on the Maglite® barrel
The right size of imprint, so the logo doesn’t get distorted at the top and bottom edges.
Make a jig, so you can engrave all the barrels at the same exact place.
The best way to get a Maglite engraved is to find a professional engraver, and one that engraves Maglites® all the time. Of course, the internet is the best place to find such a company.
Nobody buys Tally Books that already have a picture of an oil well. Why?
Everyone wants to give away tally books that have their own company logo.
Sometimes business owners want to put a picture of their own equipment on them.
Sometimes company owners want to have their own conversion charts printed on the back vinyl cover, or on the inside of the cover.
With today’s high tech printing methods, a full-color picture can be printed directly on the vinyl cover. There is no longer a need to print it on a piece of paper, and cover it with an extra layer of clear vinyl to protect the picture.
Multiple logos and pictures can be printed on the front and back cover.
Diameter tape measures are made for wrapping around pipes and poles, to find the diameter. That’s a good enough reason to keep one in your tool box, garage, and vehicle. But there’s one feature that no one talks about, until now….
The other side of the diameter tape measure is a regular tape measure, in inches or centimeters. It measures length, not diameter. So, even though it is a special tape, it is also a handy every day tape, too. Lufkin, and the other manufacturers, thought of everything when they designed these handy pocket tapes. Everyone should have one or two.
There are distance measuring apps out there, but measuring the diameter of a pipe presents a unique measuring situation.
Calibration. There will need to be some way of checking to see if the app is working correctly. You will need to measure a known standard to see if the app is measuring right. If not, there needs to be some way of calibrating or adjusting the reading, to make it accurate. In other words, if you measure a 2 inch pipe, and the app says 2.1 inches, you need a way to adjust the setting to read 2.0 inches. Otherwise, when you measure a 3 inch pipe or any size pipe, the measurement would be off.
Calibration should be done with different sizes of pipe, to make sure you will get an accurate reading at any of those sizes.
The curvature of the pipe needs to be considered. You aren’t taking a picture of a 2D object. The pipe is 3D, so your camera may not see the top and bottom of the pipe as being 180 degrees away from each other. If you are too close to the pipe, you wouldn’t see the full 180 degrees. So your measurement would be too small.
Resolution of measuring. A pipe diameter tape measure normally has a resolution of 100th of an inch diameter. Can a smart phone app be that accurate?
The nearness of the object. For calibration, we would need some standard distance from the cell phone. Maybe this could be accomplished by using an object like a 12″ ruler, placed between the pipe and the phone. Hopefully, a less mechanical method will pop up.
If you know of an app that can accurately measure pipe diameter, please let me know. If one does not exist, I’m sure it will be invented in the near future.
