WHAT ARE THE BLACKTOOTH SHIPPING DIMENSIONS?

Actual table dimension: 4'x8' is 56.078"x 121.50" (the overhang in the illustrations should be 3/4" thick)
To determine the frame dimensions, first consider using the frame height shown of almost 3' (2.86'). The width of the frame should be 4" narrower than the dimension from rail edge to rail edge (6X rail to rail is 80.078"). This will provide a 2" overhang on both sides (4X frame width should be 56.078").
The length of the frame should be 4" shorter than the desired length of the rails to provide a 2" overhang on both ends. The travel length will be 20" shorter than the rail length due to the space occupied by the gantry sides.
Two long pieces of 3/4" material will need to be placed on top of the frame with the 2" overhang on the sides and the end. These long strips of material will receive the rails and the chain mounts on the ends.

The VFD (Variable Frequency Drive) is not supplied with plugs, cable or connectors. You provide the cable and power plug or connector for the VFD. All you need to do is get an extension cable and expose the three wires of the cable and connect them to R, T and Ground. Please see the datasheet on this page for wiring information: https://www.buildyourcnc.com/item/spindle-inverter-2!2kw-spindle-novfd

Our pumps only have a 110 volt input, so you will need to purchase the pump in your country.

WHAT IS THE SHIPPING WEIGHT AND DIMENSIONS FOR GREENLEAN?

The Federal Communications Commission (FCC) is the primary federal agency responsible for safety aspects of modern-day wireless telecommunications systems. The FCC's Internet address is shown below. Recently FCC published an excellent report, cited below, to assist citizens and local governments dealing with siting of telecommuncations towers. This report contains charts and figures describing the characteristics and performance of telecommunications antennas. The report also contains practical guidance on application of provisions of the Telecommunications Act of 1996, which is the governing legislation regarding safety and siting of wireless telelcommunications facilities. Web page: RF Safety Program Page. Report title: "A Local Government Official's Guide to Transmitting Antenna RF Emission Safety: Rules, Procedures, and Practical Guidance." The Local and State Government Advisory Committee (LSGAC) and the FCC have developed this guide to aid local governmental officials and citizens in understanding safety issues related to radiofrequency emissions from telecommunications towers.

I AM TAKING THE FINAL YEAR PROJECT IN BASE STATIONS AND AIR INTERFACE. WOULD LIKE TO HAVE SOME INFORMATION.

Cellular telephone base stations are low-powered radiofrequency (RF) transmitters which operate at around 850-900 or 1800-1900 MHz (depending on the technology and region of the world). RF energy in a similar frequency range is used by many other technologies such as microwave ovens, UHF television, other communications systems, and radar. Health and safety issues related to RF energy have been studied for many years and there is an immense literature on the subject. Here are some sources that review health and safety issues related to RF energy from cellular base stations.

A fact sheet published by the World Health Organization. There is also a Spanish version available on the WHO EMF website.
Also see the IEEE EMBS Committee on Man and Radiation Report. Other reports are available through its website.
The International Commission on Nonionizing Radiation Protection (ICNIRP) has published a lot on health and safety of RF energy. See its website. The ICNIRP published an article that describes the ICNIRP exposure limits for RF energy and their scientific rationale. See "Guidelines for Limiting Exposure to Time-Varying Electric, Magnetic, and Electromagnetic Fields (up to 300 GHz)," Health Physics Vol. 74, No 4, pp 494-522, 1998.
A very detailed assessment of the scientific evidence related to health and safety of mobile telephones and base stations is in the recent (May 2000) report by the Independent Expert Group on Mobile Phones (IEGMP) titled "Mobile Phones and Health" This study concludes "the balance of evidence to date suggests that exposures to RF radiation at levels below [international exposure guidelines] do not cause adverse health effects to the general population" but that "there may be biological effects at exposures below those guidelines." Public exposure to RF energy from cellular base stations is invariably far below the ICNIRP exposure guidelines.
