** UPDATE **
So this week I managed to get the new jack stands 80% done...
Started with the base plates (200mm) and drew center lines, Cut the uprights from 38mm pipe (3,5mm thick) and cleaned them up, and cleaned the edges of the supports too...
Got some M20 threaded rod and nuts. Cut the rods (250mm x4 units and 300mm x2 units)
Then placed the nuts and smoothed the bottom nuts down so they can fit into the pipes.
Welded the bottom nut and top nut in place...
So in the pics you can see there were holes drilled in the pipe. The idea was to originally weld the bottom nut in place as a guide so that the threaded rod can move between the two nut. So I did the first one and welded it all up but then stuffed it up and locked the thread in place...
So that is why I had to cut the threaded rod shorter. Originally I was going to build 6 units of 330mm thread (4 units for the frame and 2 units for the rear end) but after I messed up the first one, I managed to cut the rest into shorter pieces so that I can still get 6 units out...
