SAM
Semi Automated Machine
These Two Machines has been Replaced by SAM 22
Actually SAM 22 did not work out to well for this job, so SAM 12 a&b is still in use.

Two Threading Machines that cut the 1/4-20 threads on the 1/4" aluminum rods that are used to make the M/B II Mounting Bracket.
They are made from two drill press heads. They are bolted down to 2 ft sq. piece of particle board. They are each driven by a small 24VDC gear motor with direct drive. The box on the left of each unit holds the PIC 16F84A board and relays for the motor. |
| The rods are cut to length, then bent 90 degrees. They are then set in the simple jigs and a simple clamp holds them in place for threading. |

SAM12a is pre programed to do the 20 threads on the long side of the rod.
SAM12b is pre programed to do the 5 threads on the short side of the rod. These have been in service since Aug. 04. Amazing how something so simple can be so useful. |
