Frame Work

Frame is DONE!!

Final fab and paint were the name of the game this weekend. I had just a couple of pices to cut and weld in this weekend and then started painting. SAS, engine mounts, and rear suspension mounts are all done. Peronally I think the engine mounts are sweet and they are beefy, 1/4 inch plate. It does still need a cross member towards the back for the fuel tank and shocks, but I am wainting on those things untill the body is on. For paint I used Hurculiner bed liner after canding everything to bare metal and priming it. The engine mounts and the front SAS hanger still need thier coat of purple but that won't be hard. It's been a long time coming, but that won't take too long next week.

  

 

  

 

Engine mounts / slow work


 

The last two weekends have kinda sucked around here. I spent most of my time painting or messing up parts and having to make new ones. I got the back half of the frame primed and ready for bed liner. I also got the rear suspension mounts painted. After finishing up that stuff I started working on the engine mounts, which I am modeling after Marlin Crawlers F-Toy.

I got everything laid out on cardboard and then started to cut it out of steel when I realized that I had forgotten to make sure the engine was sitting vertical, and of course it wasn’t, so I had to start over. That cost most of sat, so I didn’t even manage to get them taced to the frame before Sunday. On Sunday I taced them up and I was tired and had to do some brake work to my dad’s and go order some parts for the truck car so I quit.

I stopped out at the farm to get some parts this weekend and discovered that the kids out there heaved a chunk of concrete through my windshield. I’m still pissed as hell about that because it was a new windshield and they are about $300 installed around here. I’m not really sure what to do about it because I don’t know the family really well and they are letting me store my shiat there for free, But that is a lot of money and those kids need to learn a lesson and some respect for others things from this.


 

  

 

 

Major Frame Work Done


Finish welding the new frame

I didn't get anywhere near as much done over the weekend as I had hoped. I ended up getting the framing completed. The gussets and plating are not welded on yet, as we ran out of argon for the tig welder, but they are cut out and ready to go. I also got the front suspension squared away. It still needs to be welded but I am still trying to figure out how I am going to paint around the frame tubes so none of it is taced or welded. Since I am using the rears up front I decided to put the front spring hanger in the stock location. This as measured is moving the axle 2 to 3 inches forward of stock. I then put the shackle hanger tubes 42 inches back from the hanger hole and 2.25 inches up from the bottom of the frame. All I have to say about those tubes is what a PAIN IN THE BUT!!! I had trouble with the darn hole saw ceasing and then come to find out I hit basicly two major internal gussets. One of which I had to cut out with a tourch. Those stupid holes took me about 3 hours to do (I took a half-hour break from anger after the first hole), and I managed to completely destroy a brand new hole saw.

Once I got the front stuff layed out I started on the rear suspension. This went much easier. I measured the axle center position on my other 4 runner and marked that on the new chassie. Then I just started looking at it and decided to move the rear axle back about 1.5 inches. This should give me a final wheel base of 108 inches.

After tacking up the rear suspension I began preping the new steel frame rails for paint. It is raining here this week so I wanted to at least get most of the new stuff covered so it did not rust anymore. Unforcunatly Nate didn't get the new bottle of gas untill after I was done painting, so none of the hanging welding has been done yet. I hope to get that done on Friday after noon and then finsh painting and such the rest of the weekend.


Measuring to recut the old frame.

 
 
Finally welding the new frame to the old, and $1400+ in new parts laying in the driveway.
 
Heres a pic of that stupid gusset, and no I'm not planning to mount the axle on top of the springs, its just there for center pin width.

Reconstruction Begins

After a long winter I finally got to start work on the frame. I started off by building a "jig" out of wood to hold the chassis while I work on rebuilding it. this frame did not take nearly as long as I thought it would. Once I finished that I went on to looking at how exactly to make the replacement parts.

I looked up measurements and took measurements that I thought I needed before first cutting off the rear two body mounts. Knowing that I wanted to extend the chassis by 2 inches I started making templates out of poster board. The templates were relatively easy and did not take much time at all. I then stated cutting and fitting the steel tubing. Fitting the tubing together took considerable longer than I was expecting, but went well over all. The two frame rails were then tacked together. I marked out the old frame and cut it off. This is where things went south. The driver’s side frame rail is rusted quite badly from the inside. The passanger’s side is in pretty rough shape also. So I am going to cut out some more of the chassis and replace it with the last piece of steel I have. To prepare for cutting out the next part I went ahead and tacked up the new frame sections.

I am now going to mark out the original frame and cut it off again, cut out the rest of the new rails, and tac it all up. I hope to get that done near noon and then start working on either the plating work or the rear suspension mount after noon.

      
 
   

Reconstruction Plan

The frame for this truck is starting to add up to be a lot of work. To start off with the IFS had to be cut off. Then it became apparent that the front driver’s side is twisted and the rear of the frame is badly rusted and weak. With these trucks being rare here in the midwest I have decided to just rebuild this frame. My plan is to cutting the frame off as it starts the upward bend in the rear and replacing the entire back half of the frame. I will be using 2X4 inch 3/16" wall rec. tubing for the rising portion of the frame and then 2X3 with the same wall for the flat portion that extends back to the tailgate.

I am also going to extend the rear a couple of inches so I can mount the cheve springs a little farther back, and have easier bumper mounting. I am going to fish tail and plate all the joints and it should look nice once it's done. I am going to take out the little hump in the frame over the axle because it does not seem to be needed. I picked up the steel last week and ordered some parts from sky's that will be here this week. Bring the frame home Friday night and starting Saturday morning. As for the front part of the frame, I have not decided what I am going to do yet. The twist I am just going to plate on both sides to try and keep it from getting worse. I am also going to plate the outside driver’s side frame rail because of bad rust pitting. I am going to do away with the stock engine mounts and make some trick new custom ones that, most likely, will drop the engine around .5 to 1 inch. Stay tuned.

IFS junk gone

I finally got all the IFS mounts cut off of the chassis. Next step is to cut it in half and start rebuilding the weak areas of the chassis. That will prove to be a fun process ;).
