Removing material weakens the thread while shifting material elevates the density of the thread at crucial points, specifically at its root, thus enhancing its quality.
We have a load roller for the pickup, but it doesn’t really work when there is over 2000lbs of material on it. The trailer holds 6000lbs+ so I doubt any tarp is going to survive that. Great tip though. The load unroller is a godsend when we want it all in a single pile.
This year has gone down as one of the toughest years in many for the global nonferrous scrap industry and the recycling industry overall. With new initiatives getting launched in every corner of the world to reduce waste and increase material recycling for the manufacture of new products, one would think there would be less ending up in our landfills. Unfortunately, that simply has not been the case.
History, it is said, is made up of hundreds of different narratives. Which one of these we choose to tell, depends on who is telling it, and to whom we are telling it.
Oh another thing — if you trash the head of a Phillips or Robertson screw trying to remove it, here’s a trick: take a dremel and turn it into a slotted screw head. Hopefully you can remove it without the straight-blade screwdriver stripping it.
Put simply no self-respecting toolbox is complete with one. They come in various forms from retractable to fixed blade to breakaway.
Thread-forming screws for steel parts feature closely spaced threads that have a 60-degree flank angle. Such fasteners are too aggressive for magnesium parts, says Tripp. The metal will gall and seize in the threads.
These shortcomings along with the arrival of the industrial age brought along many inventions from necessity, the most popular being the Phillips screw head. There were a lot of simultaneous invention going on, and it’s not clear who the first to invent was, or who stole what from who. However, the Philips screw let people on assembly lines turn a screw by hand or with a power tool and succeed most of the time. It had some huge downsides, for example, it would cam out really easily. This was not an original design intent, but the Phillips company said, “to hell with it!” and marketed it as a feature to prevent over-torquing anyway.
The Recycling Research Foundation (RRF), a nonprofit organization closely associated with the Institute of Scrap Recycling Industries (ISRI), has announced Army veteran Joshua Daniel as the recipient of its 2018 National Veterans Stipend. Recognizing the need for financial aid as veterans seek to complete their degrees, the scholarship awards up to $8,000 to those who have served in the U.S. armed forces. The stipend covers $2,000 per year and is renewable for up to four years or the length of study.
The pride of the new transporters was mirrored in the emergence of excessive decoration that has become the hallmark of Pakistani trucks. When in 1963, Gohar Ayub acquired the monopoly to exclusively import Bedford trucks, it inadvertently created a standard form for decorative elements that continued for decades until adapted for more modern, long-wheelbase trucks.
There is a continuous thrust on renewable power production across the globe, in the wake of global warming and a sustained need to protect the […]
“Single-start means that there is only one “ridge” wrapped around the cylinder of the screw’s body. Each time that the screw’s body rotates one turn (360 deg.), it has advanced axially by the width of one ridge. “Double-start” means that there are two “ridges” wrapped around the cylinder of the screw’s body. Each time that the screw’s body rotates one turn (360 deg.), it has advanced axially by the width of two ridges. Another way to express this is that lead and pitch are parametrically related, and the parameter that relates them, the number of starts, very often has a value of 1, in which case their relationship becomes equality. In general, lead is equal to pitch times the number of starts.”
