regardless of what Y'all say or do according to years of doing "this" ...being a pseudo engineer(having slept at an Extended Stay O America oncet).....this torque arm? to the lower rollbar connection keeps me up at night. Yes you've mentioned that y'all will circle back and address these sort of things,but I'm just a bit concerned for y'alls safety ....I know you said finish seam welding will occur but will there be additional gussets at the base of the roll bar attachment????

I'm not sure what it is in this photo that you are concerned about ? It looks rather nicely done to me.

look at the attachment of the roll bar to the top of the frame rail may we have a gusset plate please????

Okay...I'd have cut the bracket for the suspension link off and run the main roll bar hoop down to the top of the frame rail. Given the number of interfaces there now a gusset to the main frame is probably in order.

In reply to 759NRNG (Forum Partidario) :

It is difficult to show in a picture, but the plated top of the LCA mount(where the main hoop lands) is thicker material than the frame rail and gusseted down to the frame rail end cap, between the LCA mount tabs. This is a closed box, and the LCA ears act as additional gusseting further down the rail caps.

The 3rd link will impart some bending load on that section of main hoop as it reacts acceleration and braking forces. However, the span from the base of the main hoop to the door bar(a gusset which is not welded in yet and not shown in some pics), is less than 12" of 1.625"x0.083". The upper link plates would likely tear themselves off the face of the tube before the main hoop will fail.

I appreciate the concern, but in this case I feel that by focusing on one zoomed in picture, you are missing some perspective of how the roll structure as a whole is one giant gusset for the frame rails, and how several parts of the structure serve multiple functions in the chassis.

I have no issue with the upper link mounts. If a car can generate enough acceleration or braking forces to bend a roll cage tube I'd be impressed. It was just the detail of the tube connection to the Ford chassis rail that looked "off" to me, but now I understand it better.  The welding looks great.Carry on !

I'm pretty sure that anyone capable of fitting and welding tubes that well can build a car without any of my  input. Carry on gentlemen.

Question.........just how far through the "hood" is the engine going to protrude? Will the valve covers be above the body line? I have visions of some T-shirts I used to see in Hot Rod Magazine  50 years ago, stuff by Ed Roth. smiley

This has been quite a journey and you have only been working on the thing for a few months. This thing is awesome. Makes me realize that I need to try harder if I plan to go to the Challenge again.

There were things accomplished today.

Flipping the right side exhaust manifold revealed an interference, so I rectified that

 

Also, CB worked on another bracket for the rear axle which neither of us captured digitally.

What's the eventual plan for exhaust routing? With both manifolds facing north, you can imagine many of us onlookers are having dreams of a certain "t" word that I won't mention... That said, a hater-pipe with tractor flap would be very "Midwest" and should net 5 extra concourse points in a perfect world.

Perhaps something similar to this $0 unit I snagged back before Christmas?

Extra dumb $0 solution- wonder how much boost that would make if you just bored the compressor housing out until nothing touches any more?

better idea: how about using the a/c compressor (make a switch for the clutch) to pressurize a tank and then use the compressed air direct to the intake manifold for instant boost at the push of a button?

Sort of like a "lag-controlled supercharger"
