67 CJ-5..... 2 yrs or less build

And that arc didn't burn you?

Don

 

Nope. High frequency tickle. Now if I was touching the ground clamp, way different story.

 

Are those 4" Wrangler springs? Just looking back at previous photo of rolling frame. Lots of arch in those. Are your shackles long enough to let those springs go flat at full flex? I got mine right on the second try when I had a 4" lift.

 

Yes they are 4" wrangler springs. I will measure them tonight and give you the length. I never measured the stock ones so I don't know what they are since I torched them off.

 

Measured the shackle length and its 3.750 center to center on the bolts.

 

If your shackles are too short you can bend the main leaf at flex. I measured my springs along the arc of the spring and from eye to eye. The difference is how much your springs will "grow" when flexed to flat. I had no problem on the trail compressing my old springs until they were flat. I only bring it up because it was an unforeseen problem that I encountered. If you add length to your shackles it will take angle out of the shackles. For example, if you have your shackle angle at 45* and you add 3/4" to the shackle length you'll find your shackles are now almost vertical. The only way to get the 45* angle back is to move the shackle hanger or the main eye hanger. That's why it's best to just tack your hangers in place until you get the Jeep back together, ie: full weight on the springs. Same concept applies to the spring perches on the axles. I had my Jeep fully assembled before I set the pinion angle and welded the perches fully.

 

Measure your springs along the arc from eye to eye and in a straight line from eye to eye. Post up those measurements.

 

That was 42.5" straight across eye to eye. 47" roughly across the arc.

 

OK, so your springs will lengthen about 4 1/2" at full compression. If your shackles are 3 3/4" center to center and your shackle angle is 90* (straight up and down) they won't allow the spring to extend fully. If you have a decent angle on the shackle(40 to 50 deg.) you'll have even less because that angle gobbles up some of your extension. Hope I'm not confusing you with my explanation. Some of that can be mitigated by using bump stops to limit up-travel on your springs. Personally I'd only use bump stops to keep the tires from hitting the inside of the fenderwell, not to limit articulation.

 

Not confusing at all.. Makes good sense. Basically saying your shackle length should be the same if not more than the difference between a spring in the rest position and flattened position therefore not binding the spring through its travel.

Didnt even think of that. Thanks.

 

Exactly!

 

Ok so today I made the kid get out of bed and help me build this rotisserie dealio. Made one other change to the pivot point which I will post a pick of tomorrow. But the jeep is sitting on it and Pielut's easy to follow plan worked great. The kid did all the welding. Had to cheat along the way cause the term "square" wasn't sinking in to well. I had all the material already except for the square tubing. 40' of 1 3/4 and 40' of 2". The leftover 2" will be for another project.

So tomorrow I finish the stand then finish stripping all the stuff off the body that I don't want. Basically I'm going to end up with just the tub.

 

You are going to love that rotisserie by the time you are done. I don't see how I could have done my tub without one.

 

with a lot of burnt skin , hair,and clothes...

 

Well I have to order some more steel tomorrow so I can have it by friday. Hopefully I can get the frame stretched and the front boxed in since its gonna be a 3 day weekend. And maybe get the steering box mounted.

 

Cut 1 is done. More pictures tonight.

 

How'd it feel making that first cut? The "commitment" cut! How much are you planning to add to the length?

 

Cutting was the easy part. I have one side all tacked in place now. The hardest part is getting everything straight and square again. I'm adding 12".

 

Ok here are the pics from today. Still have to finish welding it and plating the inside.
