A router table is an important part of a milling machine where a worker positions their work piece to mill it. There are three types: standard, rotary, and CNC. Most routers come with a table attached, but custom machines can be created by purchasing parts separately. All mills require a table for safe and efficient […]
The number of natural elements on the periodic table is debated, with some considering elements 93 and 94 as natural. Unstable isotopes and short half-lives make some elements rare. Four elements, technetium, promethium, astatine, and francium, are questionable. The number of natural elements ranges from 88 to 92, depending on which elements are included. Natural […]
Flat tables are used for surveying and mapping tasks, with a solid surface mounted on a tripod and an alidade for telescopic sighting. The table can be oriented using a compass or visible point, and multiple stations can be used for large projects. Flat tables were used by NOAA to map the US coastline and […]
Humidity tables collect temperature and humidity data in graph form. One type compares air temperature and wet bulb temperature to find relative humidity, while another indexes relative humidity and temperature to provide absolute humidity and dew point. Different units and layouts can be used, and some charts are calibrated for higher altitudes or changes in […]
Naming new elements in the periodic table follows basic guidelines: names must end with “ium,” not be previously considered, and not be named after a living person. Some elements have been named after deceased scientists, replacing the use of Greek terms or geographic locations. The letter “J” is not found in any atomic symbols or […]
A rafter table is used by carpenters to cut roof rafters correctly. The table includes the pitch and width of the roof, and is used to determine how to cut jack rafters and calculate the bevel required for jacking beams. A rafter table is a set of numbers used by carpenters to determine how to […]
When buying a tabletop oven, consider the available space and intended use. Options include convection, microwave, and traditional toaster ovens. Convection ovens cook evenly, while microwaves are faster but less suitable for baking or grilling. Traditional toaster ovens are the cheapest and most readily available. If you’re considering purchasing a countertop or tabletop oven, one […]
