For today's project, we will be finishing up the shop made machinist's jack build.
Last week we completed the main body of the jack, as well as the adjustment bushing, used for adjusting the jack-screw up and down.
This week we will be making the main jack-screw and the work support platform.
To the make the main jack-screw we will turn down stock on the lathe and then single point cut a 7/16-10tpi left handed acme thread.
The work support platform will be made from 360 free machining brass.
The brass will be turned down in the lathe, and drilled and counterbored for the screw that will be used to fasten the platform to the main jack-screw.
I will demonstrate how an integrated arbor can be turned directly into a part when there is sufficient stock, and how that arbor can be used to hold onto a small or odd shaped part that might otherwise be difficult to hold and machine.
I will demonstrate the use of a collet block for work holding in the milling machine and show how a surface plate can be used to locate and align features with work a holding fixture.
This all demonstrates how a bit of forethought and some simple "old school" tricks can be used to hold onto, fixture, and machine small or odd shaped parts and features.
