Going to cut my truck in half!

<< < (2/4) > >>

I personally had a mini truck some years ago. And from the cab back was a complete custom frame. And I know they make back half kits for the TJ. I am pretty sure phantom is running something in this sorts. Just saying. But like Clark said post some pics

I wouldn't trust anyone who throws out a specific number like 18", the true answer as with everything is "it depends".  Depending on how you reattached the frame or add in a new section and how much fram rail left you have to make a solid connection to will ultimately determine your number of inches.  Joint design will play into it significantly as well. But I don't think you are limited to not creating the wheelbase you want, it just may take a lot more work than those who cut only 18".

I am not shortening the length of my frame but, I cut my truck both on the front and the back....does that make it 1/3?  //???//

The 18" thing came from a guy who was doing something similar on a 75 f250, I think it was on the fordification forum. I may have misquoted him a bit, what he was saying was that you couldn't take more than 18" while keeping the rear axle in the same spot on the frame, which I do plan on at least until I can fork up some cash for a four link. I think I should be good to take out at least 24" with minimal trouble. Really just looking for a bit of insight this will be the biggest fab work I have ever done.

We build rat rods on the side for folks and you can cut as much as you have material to work with. I would not do a straight cut on the frame but rather do what we call a Z cut. Find a common point to measure from on both rails. Measure 4-5 times cut once. When you put the rails back together,tack one side then tack the other side. Guy in my shop was putting rails back together one day didn't tack both sides and put a heavy bead on one side. The hotter he got the one side the wider the gap got on the other side. Also cut out some fish plates drill holes in them to lay over where you butt welded the frame rails. One for each side of each frame rail. Put them over the welded joints and weld in place. Then weld up the holes you drilled in the plates,do this on both sides of each frame rail. Use the frame rail you cut out to make the fish plates.

I don't have any pics but will find some if you want to help explain what I'm saying

The explanation was excellent...even I could follow it.
