Small Machinist Jacks for "What's in your box? 2016 Tool Giveaway"

[Paul Jones]

Now that there are thousands of members to HomemadeTools.net - Encyclopedia of Homemade Tools, I am sure others are contributing tools to this year's 2016 "What's in Your Box" tool giveaway hosted by Keith Fenner on his YouTube channel.


This year I decided to make the small machinist jacks and accessories I had previously featured on HMT at http://www.homemadetools.net/forum/m...st-jacks-19843 . The new versions are made from 1144 Stressproof steel and parts of the accessories use O-1 drill rod for added strength. These jacks also have the retained 0.250" ball bearings near the bottom of the top hole in the jack screws. The ball bearings provide a smooth surface for rotating the accessories.





I also tried something new by milling the v-groove to one of the accessories using my geared head lathe and a fixture that clamps in the QCTP. The fixture locks the part in place with a M8X1.25 dog point set screw and proved to be very strong and helped produce a smooth finish using the power cross feed. This way only a lathe is required to make these machinist jacks.









The "What's in your box?" tool giveaway that also includes several machinist toolboxes is a very worthy event and a wonderful opportunity for others to contribute.
