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

[Paul Jones]

Toolmaker51,

I have the original set I designed and built, and these have served me well but I discovered some "improvements". The set for the "2016 Tool Giveaway" incorporates these improvements and much easier to make the second time around. The knurled lock nut can be removed if the space is too narrow to fit the jack with the knurled nut still attached, and the handle can also serve as a thread lock because the side threaded hole goes all the way through to the bolt. As you pointed out, I selected the 20 threads per inch to allow for a way to estimate an adjustment knowing the thread pitch.

Thank you and good luck with finding the shop where your talent will be used and appreciated.

Paul
