Earlier in the week I found time to visit the scrap yard for a look around. One of the things uncovered was large version of
the familiar machinist jack. It is actually a house jack or sometimes called a railroad jack from long ago. It had to be
sitting outside for years as it was a rusted piece of history. Heat was used on the screw housing and the top rotating part and
finally I was able to get it apart and cleaned up and even painted. These jacks are not very efficient, probably 20 percent at
best but will always work, unlike the hydraulic jack that at times needs attention before it can be used. In the casting is inscribed
"1 x 6" which I assume is one inch diameter threads and 6 inches of lift.
Here's a photo of the jack after several hours of toil and some oil. I added a handle to the find using a foot or so of hot roll material.
Of course, the Foreman had to claim my treasure as his roost.
