Well I have been thinking about putting a new frame in the Bockscar for several years.  Pork Pie started working on new canopy and top drawings to eliminate the engine bumps.  The old frame held up quite well for one that was out there for the first time 41 years ago.   The helmets outgrew the cage we installed in 1984.... we redid it... but they seem to be headed that way again, so the cage will grow a little with the top. 

Since the accident I have been trying to decide if we really want to build another car from scratch... and spend half my retirement money... with the salt in such a questionable condition.... and I have decided no!

That's no to spending half the retirement.... I think I can do it on 30%... going to reuse as much of the old car as possible.  Will it be ready for SW18? Couldn't tell ya

I have to start this by saying thanks to my first sponsor Sparky Bill Smith, he gave me the 20 ft long 29 inch wide build table he had stashed in his back yard.  I picked it up after WoS on my way home.  It needed to be mobile, so I put wheels on it, then it needed to be stable so I put retractable legs on it so it won't rotate unless I want it to. 
Started welding and squaring up fixtures on it today so I can put some pipe on it soon

That's a nice looking jig. You should be able to build something really nice using that. Good luck!

Bob,

Hmmmm . . . . .   66 huh?   Same age as I am, so I have some suggestions:

A/   DO NOT let the build budget negatively impact your suds budget.   Seriously, there have to be: PRIORITIES

2/   Refining/updating the design seems like a smart idea to me.   I'm thinkin' you are not going to want to do this over because of some small unconsidered detail.

d/   Another member of our "66" club, Tom Petty, has recently departed to places "unknown".    I'd say: "Git 'er done!!"   After all, we are all "walking wounded" at this age . . . . . .

As always, if you need anything from me, you know how to get a hold of me.    Even if it is just an infusion of "Dragon's Milk" . . . . . .

 cheers cheers cheers

FB, not to worry, that 20% is my lubrication budget...  rolleyes so I can't really count it against the car. 
Usually spend most of my money on racing, women and booze.... and waste the rest...

So I have decided to build the front 140 inches of the car (less the nose) first, that will be front suspension, drivers area, engine bay and rear suspension mounts.  Hoping to not screw it up, we have been refining this thing for 33 years.  I know I want 2 or 3 more inches of climb in room, for the knees that are not getting any younger.... or more agile...
I am trying to figure out how to make an engine mount that just installs the mount and engine in the bay to eliminate the major fight we have getting engines in and out.... it may include the removable frame rail or not... time will tell if I can figure it out. 

I will make all the curved parts and weld them to the 24 X 16 rectangular section later.

Since you are building a new chassis, consider putting the rear engine & drivetrain in a section of the chassis that will break off from the rest in a hard crash. Getting rid of the energy in a heavy component like that will allow the section with the cockpit to come to a safer stop.

One might think that the mass of the drivetrain, if still firmly attached, would slow the deceleration of the vehicle upon impact, and limit damage to that bag of bones and water inside the roll cage.

F=MA.  Reduce the mass and you reduce the force.  I think the benefits of a break away chassis is fairly well understood and adopted in a few different forms of motorsports.

Stainless, Bockscar has always been one of my favorite cars for as long as I could remember - Ben Jordan was an early and great influence on me and my brother.  I'm glad you're bringing it back and hope you can maintain a majority of it's original form.  Looking forward to seeing it out on the salt again.

F=MA. Reduce the mass and you increase the acceleration. Lighter vehicles are easier on things they run into, but that's not the issue here.

Yes, Stan. My chassis is designed to separate between the rear of the roll cage structure and the chassis members that contain the engine, transaxle, and rear suspension & tires. I like the idea of the heavy stuff bouncing along separately from the part with me in it. In a mid- or rear-engine layout this is feasible; a front engine, not so much.

Actually, it is just the opposite- the heavier pieces have more energy; that must be dissipated so they tumble down the course further.
