What's new

CJ5 wild stretch and full build (Big Booty Judy)

A little arts and CAD tonight to work towards an inner fenderwell.

Dont have to remove anything to slide it out from behind the coilover.

started shaping. Will fill the cutout with either a welded in or aircraft riveted section and enclose the top with some light rubber flashing to allow for flex.

Got this coolness today for a little extra engine insurance. If you don't run an oil accumulator, as a former hydraulics tech I would highly recommend one. 1-3 extra quarts of capacity (this one is 3, and by far the most cost effective, and the only one with billet mounts). Gives you extra time in an off camber or rollover situation to keep oil flowing at full pressure. I also bought a normally closed solenoid valve, so when the key turns on, it dumps the accumulator and acts as an engine prelube device to prolong engine life and prevent dry starts.

that's my sales pitch for the day.:lmao:

Then I prepped and cleco'd the coilover closeouts.

With plenty of roon for the fitting to clear. Going to fill the remaining gaps with rubber covers for flex.

and made a cover to close out the sides of the shock towers for a little added ooh factor when you open the hood. Drivers side is done other than mount tabs for all this crap. These will all get painted body color to really tie everything together.

Looks great. I know that was a lot of work.
Thanks. Yeah. It was a stupid amount of time and a lot of cardboard and tape to get them right. I really think it will make the front end look "right" when everything is painted and assembled. More of that making people guess what's actually been done to this thing.

Figure 4800 Fluids, fuel, upholstery and glass. Rear tank and upholstery should push it to 50% F/R bias.

There it is fellas. Not quite as light as I was hoping, but still shouldn't cross 5k lbs.
 
That's lighter than I would have guessed.
I've tried to cut weight everywhere I could. 120 wall frame and 3/16 steel and aluminum armor as compared to 3/16 frame and 1/4" armor many people do on their builds shaved a ton of weight. I was bs'ing with Rodney Hendrix (the green stretched flat fender all over insta) he's 4700+ because of frame and armor. That's nuts.
 
Holy cow! Where have aircraft rivets been all my life. This is my first time trying them (and I made some minor mistakes) but these are the best thing since sliced bread. So much easier than pop rivets, though more time consuming. They almost disappear. Also made the whole structure way stiffer. Installation was a breeze.

Dzus tabbed and installed the drivers side. That was enough for me today with the heat.

Oh no, that's not going to cut it at all. You can't drop the aircraft rivet bomb and just walk away like that.:flipoff2:

What the deal with them? I don't think I've ever even seen one in the wild. Are they the things that are hammered into place? No mandrel? Do you need to be on both sides of the part at the same time?

Spill the beans:flipoff2::beer:

They look almost flush. I dig it.

I can leave you hangin' if I want to, and there's not a damn thing you can do about it:flipoff2:












But, if you really want to know...... yes, you have to have access to both sides of the panel. They sell bucking bars, but any flat piece of steel to back it and fit you object shape will do for aluminum rivets (the better its polished, the better the overall finish)

I got mine from McMaster. They come in a few different head styles. I'll concentrate on flush head (thats what im using for now). You have to pick the rivet length for the material thickness you're trying to join, but there is some leeway since we aren't building aircraft.

You can get them in mil spec anodized if you want some color

Or unfinished raw aluminum. I went with raw. $2.89 for a 250 pack as opposed to $10 plus for a box of 250 mil spec.

you can use a hand squeeze, depending on the final finish and depth of panels

Or a rivet set (air hammer) with different styles of hammers to set the rivet.

Biggest thing is the time consuming prep. You have to fabricate, drilling some pilots, Cleco, finish drill your holes, chamfer (for flush head, round head you just drill holes) and then take everything apart and deburr all panels both sides. If you do this, with proper spacing on your holes, the panel will be water tight.


Then you put the panel back together, cleco, insert a rivet, and hammer it home, repeat til done. I'd say it wasn't worth it, but they are so much cleaner than pop rivets, and once you get to install, it's so much easier and faster to put them in.
 
Thank you for that kind Sir. Sounds like you just need to pay more attention to the prep. The tools don't seem bad or overly expensive ether.

The finished product certainly makes any extra effort worth it. It looks fantastic.

And yes, you held all the cards. All I had was begging.:flipoff2:

Forgive my scribbling and bear with me. This is more of a placemarker for memory than anything else. Here are the front and rear driveshaft lengths and angles.

Front min. (Comp.) length: 39.125"
At ride height: 39.375"
Full droop: 40.500"

Build length 39.8125 inches

Body changed angles vs axles as I was lift and lowering the body.

Front angular change through travel:
Compression:
T-case flg: 83*
Axle flg: 85* (2 deg change)

Ride height:
T.C. Flg: 83*
Axle flg: 87* (4 deg change)

Droop:
T.C. flg: 65*
Axle flg: 91* (26 deg change) (should be 6.5* max on each joint at cv, and 13* at Axle, should be fine)

Proud of the numbers on the rear shaft
Compressed: 37.25"
Ride height: 37.375"
Droop: 37.25"

1/8" overall change through travel :eek:

Angular reference:
Comp:
TC flg: 82*
Axle flg: 85* (3*)

Ride height:
TC flg: 96*
Axle flg: 84* (12*)

Droop:
TC flg: 90*
Axle flg: 83* (7*)

Max differential rear will see is 3* and 3* at cv and 6* at Axle. I can live with that for sure.

Front retube needs to be:
Stock shaft (1978 chevy K20 shaft) length (31.875")
Add 8" to tube length (stock tube length 15.5" needs to be 23.5" ; 2.0" OD tube)

Rear shaft:
Stock 09-18 dodge 2500 front shaft:
31.500" from CV flange face to center of slip flange U joint.

Length needs to be 37.25" at center of slip joint

Add 5.75" to tube
Tube length: 14.25"
Cut and face tube to 20"
Pilot inside to 2.260" to a depth of .695" one side and 2.250" pilot to depth of .355"
