Answer: A dab rig is really a sort of water pipe developed specifically for using tobacco concentrates or oils. It commonly includes a glass chamber, a nail or banger attachment for heating the focus, plus a water filtration method to cool and filter the vapor.
The fore-and-aft Middle of work over a sail system is usually marginally guiding the center of resistance on the hull,[a] so which the sailing craft will usually turn into the wind In the event the helm is unattended.[seven] The peak of the sail strategy's center of effort and hard work above the surface is restricted from the sailing craft's power to stay away from capsize, that is a functionality of its hull condition, ballast, or hull spacing (in the situation of catamarans and trimarans).[8]
The notion of truck-mounted rigs emerged from the necessity for hugely mobile drilling models, specifically in exploratory drilling and workover operations.
This is very worthwhile in endgame PvE content, wherever obtaining extra Supers available for your fireteam could be the distinction between good results and failure in difficult encounters.
It is employed strictly for output drilling. Normally, many of the wells in the sector have now been drilled, and after that the TLP is positioned over the pre-drilled wells as well as generation traces operate to the present wellheads.
Filtration is a lot less of a difficulty with dabbing, but when you're taking big dabs or accomplish that normally, then a rig with excellent percolation is finest. Percolator dab rigs neat down the vapor and filter it to get a smoother hit.
The platform is completely moored by the use of tethers or tendons grouped at Each individual of the structure’s corners. A group of tethers is known as a rigidity leg. A attribute of the look with the tethers is they have reasonably large axial stiffness (low elasticity), these that just about all vertical movement on the platform is eliminated.

The auger can be a helical screw fabricated from steel casing with curved flights that rotates as it's pushed into the bottom by a drill head. As being the auger rotates, it brings excavated product to your surface area, which allows hold the borehole open and prevents it from collapsing. Augers is rigs usually mounted on vehicles or other machines and are available in several lengths and diameters. Auger drilling is used in many fields, which include building, environmental studies, and geotechnical investigations. It can even be utilized for a number of other functions, like:
It is actually typical to run the halyards (traces utilized to boost and reduce the sail) and sheets (strains accustomed to trim the sail) to the companionway over a junk-rigged boat. Which means that regular sailhandling could be executed through the relative safety with the cockpit, or even when the crew is beneath deck.[citation desired]
On several ships, sails earlier mentioned the best (a System just earlier mentioned the lowest sail within the fore, principal and mizzens masts) were mounted on different mast segments—"topmasts" or "topgallant masts"—held in wood sockets referred to as "trestletrees".
The need to propel larger sized plus much more greatly laden boats led to the rise in vertical sail. Even so this introduced extra instability to your vessels. As well as the special creation of outriggers to resolve this, the sails have been also leaned backwards and the converging issue moved more forward to the hull. This new configuration essential a loose "prop" in the course of the hull to hold the spars up, in addition to rope supports over the windward aspect.
