SAM 7 drills the holes in the 1" sq. boom for Solid Element Antennas.This one uses Two Drill Presses, one mounted Vertical & one mounted Horizontal.While the Vertical one is drilling the 1/4" hole for the element, the Horizontal one is drilling a small hole in the side for the element attaching screw. (Both holes are centered to within .005 of an inch.) Uses almost the same transport system as SAM 6 Three IF photo sensors are used on this one, the third is used to detect a "Bolt" hole. Just like Sam 6 the master boom is clipped to the boom to be drilled, and both are inserted at the right of the machine. Each Master Boom can have up to 4 different Masters, if they are the same length. Talk about a time saver, and it does a better job too.SAM 1 - 7 are all controlled by a board with just 5 IC's - 555 Timer Chips. (SAM 1 has some counting chips too.) Let me tell you, SAM 7 really pushed the limit of what can be done with just five 555 timer chips. (SAM 7 has been upgraded to a PIC Micro Chip) From now on, I will be using a PIC Micro Chip (16F84) as with SAM 8 & 9 |
