Who had the LNC2 jacks? I'm interested. Thanks.


Scotty,

I have seen several scary looking jack designs for the LNC2, so be careful.  The main problem is that several of them have the lifting mechanism pressing directly on the floor rather than pressing part of the jack to the floor while lifting.

The attached photos show what I use.  I had a local welder construct a tripod of angle iron attached to a plate steel "floor".  At the apex of the triangle is the very top of an existing auto jack stand with a square opening at its top.  A square, hollow, steel tube is welded vertically inside the existing opening.  The lifting element is a slightly smaller square steel tube that passes up through the first tube and is raised by either a hydraulic bottle or floor jack.  In either  case the hydraulic jack sits on the floor plate during the lift so the system is very stable.  The inner square tube has a top welded on with a bolt protruding and ground to the right shape for the jack point.  Originally, there was no plate at the bottom and the jack was very unstable while lifting as nothing pressed the system to the floor.  Once I added the floor plate, all was well.
