Welding close to being done

One major challenge we had was on the jack points.  I made the "mistake" of inserting the MGB jack into our re-attached jack point and we saw it bend before the tires were off the ground.  Not good.  So we went back to the drawing board and created more structure for the jack points, including buying a 24 inch piece of 1/2 inch U channel as raw material.  Here's what we ended up with:


In the far right portion of the above shot you can see the portion that goes straight up to the "beam" in the car.  Then the jack point tended to rotate CCW in this view when using the jack so we put the additional piece of channel tying back to the body cross member.  Problem solved, here's a picture to prove that the jack will now lift the car without the jack point deflecting:


Per the prior sketch, we created pieces to enclose the back side of the rocker.  Here's the inner sill:


The inner sills were attached two ways - automotive adhesive on the top edge which slid between the beam and the remnant of the prior inner sill, and then welded to the beam itself.  This should work awesome.

Then Nick formed the inner pieces to complete the boxing in behind the inner sills, here's the blanks he created:


Then here's these pieces welded to the inner sills.  We elected not to weld them yet to the castle rail channel by the floor yet in order to facilitate moving the inner sill in/out if needed for good rocker alignment.


We got the rocker panel installed on the passenger side top edge, looks real good with good door gaps:



Finally Nick welded up the passenger side door's typical crack at the wing window.  He used a 1/2 inch wide piece of steel about 5 inches long to reinforce the crack from the back side:


We are taking a break for the Christmas Holidays.  But the remaining list of work to be done is getting short - install driver's rocker panel, weld driver's door crack, weld trunk catch in place, then weld remaining pieces of rocker panel enclosure in place while getting good alignment of bottom of front fenders.  These words probably don't adequately describe the work being done, but essentially we are re-creating most of the traditional MGB structure while also tying everything into the beam so we think we'll have an MGB that's even stiffer than it was from the factory.
