not going to do a shackle reversal?

good to see your still alive mike! hope school is going well, Mechanicl Engineering, right? i'm green with envy, you have access to all kinds of nifty tools and equipment. hehe i might just hit you up and try to con you into making something for me if'n you can.....we'll see what i can do on my own first.but i digress...


no. no shackle reversal. i really have no scientific reason why not i guess. i thought about it quite a bit though. i noticed most of the 4wd vehicles that really had to perform had shackles in the front. look at all the older WW2 and Korean war vintage trucks: shackles in the front. also i want to divert any movement away from oil pans and body or whatever.my uneducated guess also made me feel that having a pivot point in the back would contribute to more axle wrap(something i have a vauge but nagging concern about) i guess i figured some other folks had allready put a lot of thought into the design, and who was i to second guess.

probably the biggest reason is i didn't really see the need. I like getting out in the wild and wheeling a bit. but i dont do it all the time. i really doubt i'm gonna be taking this thing up anything hairy enough to worry about aproach angles. and lets face it....the lv isn't the best vehicle to try to turn into a serious rock rig.....the thing is a small bus, with waaaaay too much overhang on the back end so departure angle would be the thing that kills me. i hear that i can improve road handling though, and i'll be spending most of my time on pavement. but everything being everything....i just couldn't see what it would do for me...besides, i think it looks meaner and tougher with the shackles in the front.


i really have no justification for my decision. it wouldn't have been any harder, or much more work. its just that everything i've read never really lead me to believe that a shackle reversal would make anything much better. i couldnt find any rock solid arguements for one. i've never really seen any posts here or anywhere else that were like...yeah, a shackle reversal would make that problem go away, or not having a shackle reversal made this break.i can tell you i dont have any real experience driving a rig with a reversal...so i couldn't tell you if it makes a big difference. but all the vehicles i had with shackles in the front did just fine for me. i'm sure folks have an opinion on the matter.....i wouldn't presume to anyone they are wrong for doing or not doing a reversal, but i'm sure there are plenty of other posts where all the vagueries of shackle placement have or can be discussed.
 
so i finally worked up the stones to tackle the roof...i dunno why it waited so long.i thinking i was intimidated by complex curves. i've been brewing on how to make it happen for a while. i thought about making a template out of wood for the corners, then peening the metal into shape,or buying an english wheel. both of those options seemd to take a level of craftsmanship i dont feel i have now. and i'd probably tear my finger off on an english wheel.

i decided to further expliot my endoskeleton and simply use it to build the roof on. the old roof i didn't stomp down and measure, but when i threw a tape on it ocross the curves it was over 5'. try as i might i couldn't find any sheetmetal over 5' wide. so i got a 5'x10'. i also got a few other pieces for the sides and ends. the more my plan formulated the more i liked the idea of shaping a a few pieces rather than try and shape one big piece. all it would take is one mistake and the whole piece would be hosed. i'm not getting much more precise, but i am getting better at hiding my mistakes:p!


piecing the roof together will mean the roof will lack some of the graceful curves the origional roof had. this i can live with. i allready changed the look of the rockers, and now the roof, but i do want to preserve the factory lines of the body. well as much as i can.

i tackled the back first. i used a combination of things, measuring, marking, templates.....once i got to where all of the marks worked congruently i made the cuts.i got a new tool, a corded sheet metal snip. wastes about 1/4" of sheetmetal but its way easier to control and will pay for itself in not buying cutoff wheels(yay!). i did forget my trigonomitry lessons and made the first piece too short on the sides....well its gonna be the front piece now.

i laid my piece along the gutter and on top of the endoskeleton. mostly i just put pressure on the corners and kinda tried to let it take its own shape. luckily i'm fat enough that i could just push with my hands and use my superior weight to mold it. i gave it a few relief cuts where it looked unhappy, and some fine tuning on the sides. i tacked it from the center out along the gutter first. the c-clamps would kinda push the metal so i held it in place while i tacked it. i gave the excess on the top a trim, sliced it into little tabs, and tacked it to the skeleton. be working on the sides today....wish me luck!
 
forgot pictures, sorry.

the front was just slightly easier.the metal laid down a bit easier 'cuz the angle to the skeleton wasn't as steep. i was a bit more familiar with the process also. after saying all that i kinda mangled the corners a bit. ones not too pretty at all. it will be under another piece of metal though. no sleep lost.

i have been thinking a lot about the gutters though. the forensic evidence leads me to believe that the gutters were the downfall of this vehicle. well that and being 45 years old, and sitting in a field for 10 of em. the gutters didn't seem to divert water, just retain and channel it into the body. thusly i have decreed: the gutters gotta go. i will exploit them by folding them back over the roof panels i'm installing. maybe use some seam sealer on that joint. it dosent matter to be if i get dripped on getting in or out, as i'll probably be in the rain or snow anyway. if'n i have to i'll put some smaller ones over the windows, just to keep drips out of the cab.
 
looking good!
You may be onto something there with the no gutters idea.
 
finished the sides of the roof. used shorter sections that i could bend on the brake. not a whole lot of bend on 'em, just enough to match the skeleton. working on the big sheet o' metal now, big pita.
i did get some motor mounts in the mail today, good thing too. the 327 mounts must have been way up at the front of the motor. if i re-used those the fan would be through the grill. hopefully payday i can get some u-bolts. i'd like to get all the drivetrain, suspension and rear axle on. then i can measure for drivelines, pinion angles etc. hopefully soon i can have a rolling chassis.

Great Idea !

I"m impressed on your roof !! nice to see some other ideas on fixing the LV rusted roof problem !!! Good job !
 
Porten, you still around, bro?
Got me worried here.


Hope all is well, this is a pretty cool build.
 
Whatever happened to this guy? This was a wicked build.
