Good quality 100% ASTM A449 Hex Cap Screws to Bolivia Manufacturers

The balance of forces is very precarious. The dexterity is very inportant, and also very important to have time and patience. I spent two days to find the right balance of all the elements. Shape and weight of the spinner, alignment of the magnet base perfectly level, align the axes of the two ring magnets. For me it was the most challenging experiment done so far.

the top is made with a pencil, cut into 3.3 cm. on the tip of the pencil I glued a piece of aluminum foil. To fit the ring I used thick rubber made from an inner tube of a bicycle, but thickness can also doing many turns of electrical tape. To add weight, I attached magnetically 3 washers iron magnetic ring.
Pay attention to detail, this experiment is not easy. A tape around more or less change the weight of very little but can make the difference.

For this experiment I used these two magnetic rings.

PRE-Engineered Building System

*Characteristics

P.E.B. is an abbreviation of the Pre
Engineered Metal Building System and provides space efficiency due to its long
span structure of up to 90m without an interior column.
It is a 21st century construction model with functionality as well as aesthetical beauty, with its cutting
edge materials and constructional aesthetic design.
It is a new construction method that can be suited 100% to the customer’s needs and wants in all stages of new constructions or extensions of existing buildings.
It uses a cutting
edge design program imported from LOSEKE, a US company, reducing construction time and cutting costs from 20% to 40% when compared to the existing steel structure method.
It is manufactured precisely by computers so there is no need for onsite welding, so the construction time decreases substantially.
Uses: Large-scale factories, warehouses, logistics centers, shopping centers, sports facilities etc

Lighteight-Engineered Building System
*Characteristics

LEB is an abbreviation of Lightweight Pre
Engineered Build System and is a high quality lightweight steel skeleton system developed first in the United Kingdom for use by small/medium businesses for constructing factories or warehouses. It is considered the most competitive out of all existing structural systems.
Through precise calculations with an exclusive LEB program, a high level of safeness and more importantly economy can be achieved, with cost reductions of up to 50% possible when compared to existing steel structure systems.
The materials manufactured at the factory can be easily put together on site with only bolts, and direct construction by constructors is also possible. Disassembly is also convenient and it is 100% recyclable.
Construction time is also very short, with a 200 pyeong sized building taking about 15 days from the order to construction.
Uses: Small/medium business factories, warehouses, agricultural machinery storage, granaries, barns (cattle, pigs, chickens), mushroom houses etc
