This might sound like somewhat of a dumb question but Im going to go ahead and ask it anyways. Building a set of leaves for a roundback wagon and last time I flat stacked them I had it too low and it got driven over. I am asking whether I should leave them all upright and not flip any or if the leafs would resist bending up better if I flipped just maybe one or 2 leafs to give resistance down? Im allowed to chain the rear humps and it will be tight! Right now I have all of the leafs upright but got to thinkinig maybe i should flip at least 2 to give resistance back down. maybe its just a dumb thought...

no thats not a dumb question. i flat leaf a round back and tore the quarters right off the floor. so i would maybe just flip couple but leave alittle arch to them.

I had 7.00 15s on the back of the last one that I ran and it was still sitting too low in the back. The main thing that I am wondering is if they are all left upright without flipping any leafs, will it have as much resistance to stay straight since the leaves will be more naturally laying with each other as opposed to having a few flipped where the flippped leaves would be putting pressure back on the other leaves. If that makes any sense at all of how im looking at it

Anytime the leaf flexes , at all , no matter how miniscual of an amount, the car will be able to buckle inside the radius of the leaf pack.....
Best solution, cold roll steel handbuilt leaf pack with the minimal amount of stagger that you can squeak by with, plug welded and straight with the top frame shock tray tied to the rear housing
Next best solution, restack the entire pack to make it straight
Still pretty good solution, leave pack alone and tie it to package tray and with the car on the ground, slowly take a acty. torch and heat the back of the long single leaf spring where it meets the shackle. Do it in the center of the exposed section between the leaf bolt and where the second longest leaf stops... If you heat it slowly with weight on the car it will slowly ^ up and start to roll back up over itself. Dont push it to far or heat it more than one time, it will become slightly more brittle. Some guys claim to have snapped them off after doing this but i probably ran half a dozen clamshells back in the day this way before peps started pulling leaf packs and modifying them and cars always performed excellent. The only place i used to add a leaf back in the day was in the pass side rear piller where it came down to meet the tailgate..
Run a mid size tire in the back and if its a 75/76 roundy with the bigger rear bumper i used to weaken the back side of it in the center where the license plate mounted so bumper would buckle in , in the middle. Never had a problem with em being too low myself.

I take the bolts out of my rear bumper put a small weld on each side so the bumper will buckle under then fall off if the bumper stays on is buckle the frame if you beat with your tailgate your pushes in

Been trying to look how flat stack can't find any threads on it. Do I just use ready thread and have some holes through some steel plates and have the leafs every which way inside of the ready thread and the plates and keep tightening down till it's flat?

I do remember there used to be threads before everything was lost, good pics and stuff that I would love to see back.

The basics are as you described. I get the pack in the order I want. then tighten the nuts on the all thread.I build mine with the main leaf installed on the car. use a big old bottle jack with a chain that's connected to the base of it. Wrapped over your pack. To the other side of the bottle jack base. Jack away. Throw some c-clamps on there. And tighten your all thread only as an alignment pin. And tap and smack the stack with a hammer.so the leaves settle and stay in line. If u don't smack. The all thread will be at an angle when your finally compressed

DO NOT USE ALL THREAD TO COMPRESS THE SPRINGS!!!!!!!! sent a bolt flying through the roof of my buddies shop. Pulled the threads clean out of the nut

Dont have any pictures but if you weld 2 pieces of c channel with the c's out and a piece of 1/2 plate top and bottom then torch or drill a hole in one end and weld a nut on that end and use a piece of 3/4 allthread to compress the leafs together. The other method I use is track clamps and a piece of all thread to keep the leafs lined up.

I have access to a brake press with a hydraulic jack. What I was thinking of is is stacking all of the leafs to go for flat leafing take 2 pieces of c-channel and weld something on the sides of the pieces of c channel that goes the height of the stack and put that in the press and press it down with the channel holding it in place. I hope I described it well enough this would be my first time as well. Good or bad idea? Flat stacking 9 leaf springs together off of a chevy 1 ton.

We have built several sets, we alway put half the springs arched one direction and half arched the other direction back to back. Put your center pin in then start with either a BIG and I mean BIG vise or a couple big c-clamps and start near the center pin and work your way out to the end of the springs clamping them together as you go. When we were building them we could run 7 springs so we put 4 arched one direction and 3 arched the other direction.
