WORKBENCH-JTA 2011

GAS SPRING WAS USED AND ALSO A LINEAR GUIDE BEARING WAS USED AT THE BACK FOR GOOD ALIGNMENT. ROLLER BEARING WAS ALSO USED FOR ALIGNMENT OF THE ROD. I USED THE SAME MECHANISM WHICH IS BEVEL GEAR FOR THE UPWARD AND DOWNWARD MOVEMENT. I PUT SOME ROLLER FOR EASY MOVING IN ONE PLACE. ROLLER IS OPTIONAL. THE BASE FOOT CAN HAVE ADDITIONAL HOLES FOR GAS SPRING ADJUSTMENT. I USED SCREW KNOB FOR LOCKING.
