Pzuzu The Isuzu Build (RIP)

Yesterday I did my outer body mounts. Quick photo of them done.

Then came the sucky part of the day. Removing the 2x6 1/4 wall tube rockers from the chevy since its $130 worth of metal. I was gonna use 2x6 3/16ths but I already had that sitting there on the truck and it was gonna get scrapped so I figured I should re-purpose it.

I think Harvester of Sorrow was written about taking parts off of past loves...

Rear bumper shat. Frame side of the truck.

Bumper side of the mounts.

I had the bumper mounts just the two piece of 3/16ths plate with the holes in it. When the plate is slipped over the box tube on the truck its super beef but once you pull it off its dinky so I was concerned and decided to put the 45* guessets I had bought from kert 6 months ago to use.

Now its super beef all the way around.

Obviously this is just the center basis of the bumper. I feel its easier to build off a piece of box tube rather than build it straight from plate.


Laura took this cool picture of me.

So I took a picture of her ass.

Im gonna try to finish the bumper tomorrow. I plan on doing a compound angle and taper into a piece of 2x3 box tube under the rear corners to the wheel well. Im gonna use a piece of 4in 3/16ths flat stock on the top to close the bumper to the truck and use a piece of 2in flat stock on an angle on the bottom to give the bumper more dimension then just being square tube.
 
Put wings on the bumper tonight after work. Still gotta plate it all in, put a piece of flatstock across the top, pintle hook, shackle mounts, swing out, and the extensions that go under the rear quarter to the wheel well.

:doah:

Yeah I got some more, err alot more work ahead of me. I did order a swing out pivot from kert though.

Got the metal to finish the actual bumper structure itself. Swing out tire bearing is on its way and I got a latch from McMaster.

I realized last night its gonna be tricky placing the pivot so my back doors can open all the way...

Also taking the tcase, trans, and motor out of the chevy today.
 
Finished my bumper today. Cant believe how long it took me but it came out great. Cant get photos up photo bucket is being stupid.
 
Finished the bumper. Also have some shots of the mockup and hanging it for paint. I decided to go a little wider on the side guards looking towards the future putting tube over fenders for protection so the width now will make the bends easier later on.

Mocked up

Capped, grounds down, hanging for paint.

Painted and mounted on the truck. Unfortunately I need to raise the passenger side of the bumper about 1/4in. Considering the fact that its gonna have recovery points and a hitch on it in the future slotting the holes is not an option as the bumper will just move. So I have to weld the holes up and redrill them higher.

He likes to hang out with me under cars when Im not making too much noise.

My tire carrier hub kit came from Kert today so wed Ill probably start making a spare tire carrier.
 
Side tube fender protection...sorta like the Aussies do where they have tube that follows the rear lower body line around the wheel openings, becomes sorta nerf bars/rock rails, and then follows the front fenders up and to the front bumper?

Cool. Always kinda digged that on the Aussie rigs.
 
Looking good.

I liked my old Isuzu pup. Tough as hell. I beet that truck to death. Twice. Wheel that Zu and enjoy it. They are a lot tougher than most people realize.
 
Got my tire carrier 85% done today. Only have a few pictures of when it was light out still. I got the whole swing out done, tire mounted, and tomorrow Ill finish making my highlift mount and finish the pads that the swing out lands on so its solid.

Spindle frenched into bumper corner

Arm. Made of 1.5in box tube with an 1/8th wall.

Because of the way the doors open out I had to wrap the spindle and the latch around the side of the bumper. Was kind of annoying, especially with the latch which Ill have pics of tomorrow.
 
Finished shots of the tire carrier.


This is how I wrapped it up last night. Painted, tire on, no supports under the arm when latched, highlift mount not done.

No tire on it.

So that was my basis this morning. The swing out really needed some feet for when it was closed so that was the first order of business.

Off to wally world for a $2 plastic cutting board. Easiest way I know of to get a sheet of Delrin locally :D

Much to my dismay this did not fully solve my wobble problem with the tailgate closed. It did help and was definitely needed so that the weight was off the spindle when closed. Especially since I plan on making a ladder over the smaller barn door up to the roof rack.

Heres the clearance between the door and the swing out.

SDC13215.jpg


And a couple shots of how I clearanced the tube at the end for gripping the release handle. I plan to cut, bend, and reweld the handle to get it closer to the tube. That was the point of what I did.

Heres a short video I made of the wobble the tire gets up top. It doesnt move too bad when driving but this is the thing that leads to spindle failure after a few years. I dont want that.




I have a solution for this. Seen here are the old holes for the door mounted tire carrier.

SDC13216.jpg


I was originally going to make a piece of flatstock with an adjustable rubber bumper on it to preload the carrier and prevent the wobble, or at the very least make it so its only moving off the bumper when its opened.

Then I had a thought back to highschool. Earth magnets! They have ridiculous holding force. At first I thought theyd be too expensive but after some googling I found a 2x1x1 magnet with a 90lb holding force!

Thats no joke and would definitely do the trick. Plus its only $25.

O and I also plan on adding "lanyard" sort of with a length of coated 1/4 steel cable going from the 45* brace on the spindle to the bumper, just in case.
 
Well when I first saw the 2 bolts holding the tire I thought, this is going to wobble bad, then I saw the pic with no tire and I saw the brace, it's not good enough to hold the back of the tire.
You need that backing to have a cross tie somewhere so the tire has a triangulated backing. 3 spots for the tire to lean on and then tighten the bolts. 3 bolts would be better but 2 could work as long as the tire rests against 3 non linear spots.
PLus the bar that is the base of your carrier is also not stiff enough it's linear and it cannot hold the leverage of 2 feet of tire weight wobbling.

Looking back at the pictures:
can you weld another bar from the top of the spindle that ties at the top of the tire carrier and then cross tie it a couple of places to the lower one.
It will really stiffen things up.

Green is what I was already going to add. This would provide that 3rd "rub" point for the tire. Right now it already rubs the existing triangulated bar and the vertical bar.

Red is what your saying to add correct? I have it drawn to the angle but I could put it all the way to the hub. The thing is that the tire is solid left to right. I dont see how bracing it more horizontally is going to eliminated front to back wobble no?

Re-reading what you said you dont think the base material 1.5x1.5 1/8th wall is stout enough for the length of the swing out?
