2014.08.18 - UPDATE! - HALESTORM & THE IRON MAN.......!!!
Saturday "honey dos" were completed, and the weather was perfect on Sunday morning...... it was time to roll up the garage doors and get to work!!!
OK..... the shop was a bit messier than it usually is at the START of a build day, but the other critical items were all there...... there was a hot cup of coffee and some fresh iTunes downloads of some Halestorm (thanks to Zim for posting that music thread!)

TIME TO ROCK OUT!!!!!
There were still 3 more bracing plates that needed to cut and shaped for the upper strut tower area. So that got knocked-out first... (this photo also shows my highly-secret and proprietary "radius drawing tools" in three different sizes.)
I put a fresh 36-grit on the 20" grinder so that I wouldn't waste any time, and after a couple of hours of fussy shaping and fishmouthing the remaining plates were all tack-welded into position.....
Another little-known secret to getting super-hero type results on a garage day is to make sure that you get plenty of iron supplements! By the time I was ready to weld those brackets there was PLENTY of extra iron (and cutoff wheel debris) in my coffee....... YUM!
It was finally time to spend a lot of quality "under the helmet" time with the welder.... there is nothing like extended periods of welding to really sharpen-up the skills again.... the first welds of the day were kind of "meh", but by the end of the session things were looking pretty tight and professional...
Here's a fun shot of the upper strut mount (from the top side) that shows the HAZ from all the new welding that was completed. Obviously, there was PLENTY of heat and penetration, and you can see the cross-hatch pattern of overlapping plates and the way that everything ended up tied to the triangular tubing structure that surrounds the strut hanger.

I think this is going to work well and I have no remaining concerns about it's strength or long-term durability.
Once the welds had cooled a bit, I pushed the entire workbench over to the front of the truck to prepare to re-install the engine cage..... this is no small feat now, as it's been getting heavier and heavier and more awkward to handle....
In a move that OSHA would certainly "NOT" approve... I basically stood on top of the rolling workbench, then used my shoulders to lift the cage up....then slowly walked along the tops of the framerails to get it into position before slowly lowering it down onto those new "saddles" and against the firewall area..... The saddles actually make it a lot easier than before, the cage can't really fall off the frame to either side once those saddles start to engage. In effect, it sort of finds it own way as gravity pulls it down.
Nice.
The two front engine bars up to this point were still only "tacked" to the perimeter hoop....and one of the mounting plates had already fallen off when it's single tack weld broke... so with the cage completely bolted and torqued-down tight it finally seemed like the right time to rework those front plates, and get those bars squared-up and positioned correctly.
Check that one off my list as well.....
The only lingering issue related to the engine cradle / strut mounting scheme is that I'd still like to add a couple more tubes (animals) to my farm....

Ideally, something that picks up that unsupported front "triangle" on the perimeter bar and locks it down to the framerail like everything else..... remembering that this is an area where the tire will live under "full stuff" articulation, it makes sense to use a curved tube to provide adequate clearance. Having a curve will also help to define the "wheeltub" shape and give me a good starting point when I start trying to fit some sheetmetal (or fiberglass) wheel tubs.
So here is the current idea rendered in small-diameter solid rod, to show the possible tube shape and position:
I think a "rolled" tube would look pretty cool for this little detail, but I don't think I'll be able to create a smooth looking one with my currect tubing bender.... the best I could do is bend a couple of degrees...shift the tube maybe 2", bend another couple of degrees, etc, etc. I'm sure I could get a quasi-curved shape but I doubt that it would have the smoothness of a truly roll-formed part???
Now that I've written all this.... it sure does seem like a pretty big day's worth of progress after all.....
