Start of the DS engine mount

I was planning to post when this was done, but I lost a few days to doing actual work in the evening.  I also posted now since this is a pivotal day:  This is the first day where my effort takes me closer to a working car instead of further from a working car.  I always feel better after that key moment.

Here is the space to be filled with the mount:

 I had some 4 inch 3/16 thick box tube around so I decided to use that.  Since the plasma doesn't leave that nice of an edge, I started cutting with the cutoff machine, which was epic.

 I decided to try the plasma with a guide.  It doesn't do bad.  I just left it a little strong, scribed the line I really wanted then used the bench grinder to take it to the line.  MUCH quicker.  Abrasive cut off machine cut 5 inches in about 20 minutes.  Plasma cut 5 inches in about 10 seconds + 5 minutes on the grinder.  In the image below top edge was plasma (shown pre-grind), bottom edge was cut off.

 Plasma with a guide:

Here is the tube in the car.  Yes, there will be more bracing to be added to the mount, don't get excited.(even though a quick FEA indicates that this actually is enough...)
