The Machinist Jack
Machinist Jacks are simple projects that use only basic techniques. Each jack consists of a long nut cut down to length and machined flat on one side for use as its foundation.
The top loose piece is also knurled and equipped with an all-through hole to accommodate a hex key, helping it remain still and avoid slipperiness.
Early Life and Education
The Machinist Jack is an adjustable screw jack used on drill presses, milling machines and planers with adjustable screw and swivel head that can be set at any position. Crafted out of cast steel for greater lifting capacity (approx. 454kg (1000lbs), production time should not take more than several days by following some basic techniques. You will require 1″ round or hexagonal rod, two nuts, a 1-in. long 5/16 – 24 machine screw and an 11″ long 5-jaw chuck, tailstock drill chuck and lathe for assembly.
Achievement and Honors

Machinist’s jacks are a type of jack screw or jackscrew (a type of jack operated by turning a leadscrew), featuring an adjustable screw and tilting swivel head for levelling purposes on drill presses, milling machines, planers and any other place where levelling may be necessary. Their lifting capacity approximates 1000 pounds.
Machinist Jacks are simple projects that you can complete using just some steel rod, two jam nuts and a long 5/16-in machine screw. In addition to serving as an excellent way of learning lathe techniques, this project offers another convenient method of testing them at home! You can find one online at an attractive price point.
