    I didn't have to go to 90° on the bottom bends, but since I had to bend the leading edge of one and the trailing edge of the other (because it is too wide to fit below the bender; only above), it made my math a lot easier. I was willing to burn 2 feet of tubing to save 12 redoing it.

    The work is great so far. I do have one concern. In a hard roll over I am worried the bolts through the dash will sheer off and the front of the passenger cage will collapse. I know you want to keep the doors as open as possible but I think a solid post down to the floor plate from the front hoop would be a better option.

    It never crossed my mind, because I just assumed the .120" wall tubing would collapse or 'give' long before the bolts would shear.

    Some quick calculations with some numbers I found online.
    Tensile strength of grade 8 hardware (150,000 psi) x section at minor diameter of 3/8"-18 (.0678 sq in) = 10,170 pounds of shear per bolt x 4 bolts = 40,680 pounds per plate (plus overcoming of the friction of the plates).

    I guess it's a risk, but then again, any of the plates could be under the same risk with the right impact. If you guys think it should be considered a real concern, I could probably fit 7/16"-20 bolts in there. That would bump it up to 69,000# per plate if my calculations are correct.


    I was just ready to hit "post reply" and thought of something. I can drill matching 1" holes through the center of the plates (inside the tubing) and weld in a short section of 1" round stock as a shear pin. That should fix it for good. (y)

    Thanks for looking out for me.

    I just crunched numbers on the shear strength of 1" round stock and they are low. I'll use a big grade 8 bolt shaft and be careful not to lose the hardening while welding.

    I think my calculations are right?

    1" grade 2 = 4710#
    1" grade 8 = 117,750#

    What do the future seats look like, Containment/ racing? What will the seat belts be, full 5 point? What will the head and neck restraint be, Hans device or doughnut? Will helmets be worn at all times? I don't think that the occupants of the vehicle will know if the bolts held or not........
    I don't mean to sound like a smart donkey, but unless you have some serious safety equipment, and use it properly, your most likely dead before the 3/8" grade 8 bolts break. I have never flipped a race car, but I have been in a 80mph to zero in to a concrete wall, t boned a car while accelerating and many others. Car was trashed but I walked away due to all of the safety equipment above. My dad on the other hand had a basic seat with 5 points and a helmet with no neck support. 60-70mph while accelerating hit another car head on that spun. He fractured his atlas vertebrae when his head/ helmet hit the steering wheel. He is very fortunate to have the mobility that he has today.

    Who wears a helmet in a Jeep to get ice cream?

    The side-bars on my 3b had been through hell and back. They took the most abuse of the whole cage. They'd repeatedly get smashed against trees and rocks to the point that the leading edge was smashed flat when I finally retired them. This is the front DS mount, and the reason I hadn't given any thought to the structural integrity of the plates in question.

    I just want to know the date of the ecj5 group ride in N. Idaho when the Varg is revealed. I'm putting it on my calendar and I'm coming.

    You have a 2024 calendar?
    I might have to drag the 3b to the trails one time this summer.

    Maybe I can fit it in the dump truck.

    Finally got this PITA front hoop fit. Something is out of whack... I didn't have time to figure out if it's the tub or the windshield, but the one side sits 3/4" lower than the other when I line it up to the windshield. I know the tube legs are identical from side to side.
    Held in place with sticks and tape at the moment.

    Looks fine from here with one eye shut and my head leaned to the left!

    The question my brother always poses when we are working on cars and confronted with small alignment issue is, "can you see it from the drivers seat?" If the answer is yes, multiply the alignment error by your personal OCD constant. The resultant will be number in hours you should devote trying to fixing it.:D

    This is the color I want to go with for the cage, and she wants the body a mid/dark blue.

    Front hoop is welded and in. That thing is solid! I can finally get the windshield into storage and out of harm's way. Now I can put in the spreader above the cowl that will support the steering column. I'm reaching an end to what I can do, materials-wise. I'm about out of tubing, and I need a Pull-and-Save run for steering and brake parts and a radiator.

    [​IMG]

    Oh yeah... the alignment issue was the windshield frame. I'm still not exactly sure how, but it sits a little crooked on the cowl. :shrug: Probably just in the adjustments.

    Great color for the cage. Race car cages are grey so cracks show.

    My roll bar in my Blazer is grey. I bought it from Jackman Wheels at there garage sale. The bar is 4" round, but it fits with blocks perfectly...

    The whole family has been sick except for me, so I've been playing doctor (and plowing snow) instead of fabricating.

    Back at it.

    Major milestone today! All the front suspension components are done! (Fabrication-wise.)

    I made these brackets that bolt to the lower coil buckets. The lower tabs hold the spring in place at droop, and the upper tabs are the sway bar link mount.

    For the links, I cut up the stock Grand Cherokee links and welded in a section of 1/2" pipe.

    [​IMG]

    It really stiffened this thing up!

    That looks like Gloss Navy Grey, which is the color I'm painting my old trailer, with the fenders being Navy Blue!
    Great combo!!!!!!

    Well I mean, if that's the best you can do, I guess it is alright :D

    Impressive engineering and execution as always sir! (y)

    This is the picture we've had on our computer since shortly after we bought this jeep. (Just a random pic off the internet.) She loves the look of this one, and it's sort of the inspiration for the build.
