Keeping the hump from bending?

<< < (4/4)

Hey this is Denny,
   Come to help you on the hump thing.I have been building my Pinto wagon derby cars the same way for about six years now.I am a consistent winner.
   First off bolting a gas tank to an area of the car that bends is kinda silly.You are asking a container with gas in it to re-inforce your car?
   Most places around here make it mandatory to run a door bar behind the seat.(from post to post)I run a 2-1/2 " door bar across,then from that I weld in a piece of steel from the door bar to the floor.On the floor I always weld a piece of flat stock down first.@3" X 6".To this day no official has questioned this because it is part of the door bar system.
   There is a couple things to know about where to place your dash bar also,and the one other thing that it can do for you.This is one of my secrets.
   Also in the rear area of the car there is a spot where you can weld in a piece of metal about the size of a fifty-cent piece that adds incredible strength.No one has ever found this.Even after being told to look for it.
   My best advice-when you get done wrecking your next Pinto,don't haul it off right away.Sit down and have a couple of beers with it.(Before you start drinking the beer jack the car up so it is safe)Then crawl under it,over it ,and look all around it.Pay close attention to where the car bent and tore open.Then look at a fresh car and decide what you could do different next time you build one.This was advice I received when I was eighteen,I am now forty.I still demo,and I still do this.I believe that this has taught me the most over the years.


                     When in doubt,hit 'em head on as hard as you can!
                     Especially when the other person isn't expecting you 
                     to turn into them flying across the track.I love it!I     
                     think I have actually scared people enough that they
                     broke their flag!

       More to come!  #68
