  • wHAT IS THE SMALLEST LENGTH SHAFT I CAN USE FOR YOUR #25 DRIVE SPROCET?

    The hub length of the drive sprocket and the other mechanical devise that is used to connect on the shaft will determine the length of the shaft needed for use with the drive sprocket.

    The hub lengths for our drive sprockets are 1/2". So if you are connecting the drive sprocket to a motor, your motor shaft will need to be at least 1/2" in length.

  • WHAT ARE THE HEALTH RISKS OF LIVING NEAR A CELL PHONE TOWER?

    There is very little radiofrequency (RF) energy exposure to people inside a building from a cellular base station located on its roof. There are several reasons for this. First, the transmitters operate at low power levels. Second, the antennas are normally mounted near the edges of the roof and are aimed away from the building. Third, most cellular transmitters use "high gain" or panel antennas. Such antennas transmit most of their energy in a narrow beam (in the vertical direction) from their front surfaces, away from the building. They radiate very little energy downwards towards the roof or backwards from their rear surfaces. Finally, building materials absorb a significant fraction of the RF energy passing through them. As a result, the RF signal levels at any location inside the building are invariably low and far below safety limits. The situation might be different in some locations on the roof itself. RF signal levels close to (within a few feet) and directly in front of cellular base station antennas can easily exceed safety limits. Some precautions are needed to prevent people from walking directly in front of the antennas while they are transmitting. This applies also to paging and other systems that use rooftop antennas, some of which transmit at higher power levels than many cellular base stations. Kenneth R. Foster, Ph.D.

  • WHAT ARE THE BLACKTOOTH LENS SIZES AND FOCAL LENGTH SPECIFICATIONS?

    The lens is 20mm wide and a 50.6mm focal length (the one included). This lens will stand up to at least 30PSI air assist.

    The mirrors are 25mm wide mirrors.

    Focal length is the distance from the lens to the material for the laser converge into the best focal point. If a lens is listed as 2". You measure 2" from the lens to the material, this will be the tightest point the laser can go before it starts to re-expand again losing focus.

  • WHAT ARE SOME USEFUL MODIFICATIONS CAN APPLY TO THE BLACKTOOTH LASER CUTTER?

    Temperature probe monitor. Very valuable. This keeps you up to date on your coolant temperature levels.

    Voltage meter. This will tell you the exact level of voltage/power you are running telling the laser to run at instead of an arbitrary mark on a drawn wheel around your POT.

    Ammeter sensitive to 1mA. This will be sure your not over driving your tube and reducing it's life significantly.

    Hour meter. This will tell you exactly how long your system has been 'on' giving you a more accurate bead on the length of your tubes life.

    Exhaust fan upgrade. The current fan included is 100CFM. You can buy 120mm fans that push 250CFM and I have included a guide on how to go about doing this here. http://buildyourtools.com/phpBB3/viewto ... 8cdd1802bf

    To push the exhaust fan even further, if you have the room/power, I would highly recommend investing in a 600+ CFM "Dust Collector" system. 250CFM is still not suffice to draw all the smoke that can come off of 3mm or 1/8 MDF cutting job.

    A cutting surface. I bought myself a aluminum 'egg crate' mesh from my local HVAC company. They are used a cover for fluorescent lights and work great for low impact cutting surface. They come in 4'x8' sheets and are easily cut to fit. The other side is if you can find a steel honeycomb cutting bed to fit. These can be quite costly or fairly affordable depending where you are looking. The benefit of a steel honeycomb is you can use high power magnets to hold material down.

  • WHAT ARE THE DIMENSIONS FOR GREENBULL TABLE?

    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.
