Short history of the Original Ramchargers

https://www.youtube.com/watch?v=LT5LG-mJua4 is a 22 minute history (late fifties) of the Original Ramchargers club.

This was done a few years ago. I'm 82 in 2018.

Re: add an antiroll bar?

Just remember that an ARB "works" only if there is roll. In other words, it can never completely solve the problem. It's like that old "halfway to the goal line" football puzzle. It's better to dynamically reduce or eliminate the problem

General comments on ladders

You've seen at least a zillion ladder bar cars in the pits. Here's a thought: Have you ever seen a ladder bar car with only one ladder? Of course you have! This would include all of the early Fords and Chevys. OK, they were called torque tube drive cars, but they were actually ladder cars. The torqu...

Re: Weight Reduction

If you're REALLY serious about reducing weight, I saw a neat trick on a Mini Cooper. The rules required 2 operable doors. This car's "doors" were flimsy Fiberglas pieces that hinged at the middle of the top and opened like a 300SLR. They weighed a few ounces each.

Re: Ladder Bar Mod

Put a rubber mounted bushing or a Heim at the front of the block marked "Solid" and it's great. This does have an advantage over Ron's design in that finer adjustments are available. The price is a bit more time to make the change.

Re: Ladder Bar Mod

Don't think it would be all that difficult. The following would be the procedure with the 3 Heim design: Place jackstands forward of the frame brackets with enough load to stabilize the car. If the car has positive preload.... Should have been: If the car has NEGATIVE preload.... http://www.racetec...

Re: Ladder Bar Mod

Not sure how one would use your idea on a leaf spring car.... My bad. I didn't read your post closely. Still, this presents an interesting design problem. If the front of the leaf spring could be somehow "captured" in a piece which embodies Rod's design concept, it would enable a wide choice of ant...

Re: Ladder Bar Mod

I want to put some of those ladder bar adjusters on my John Trac's.. Looks like they would be handy. Okay, but use Rod Cole's design and not mine. Both a brick and a flyswatter meet the design goal of killing a fly and are thus flawless. Compared to Rod's design, mine is the brick. http://www.racet...

Re: Ladder Bar Mod

What about the preload, have you ever try to remove a bolt out of preloaded rod end? Your gonna have to unload it to get the bolt out. I have solid rod ends in my set up, it going to be a little hard even doing it with jacks and jackstands. Don't think it would be all that difficult. The following ...

Re: Ladder Bar Mod

A poster on the Yellow Bullet forum has offered that which I consider to be a better design. He pointed out that, rather than moving and rotating plates, why not simply have 3 Heims, arranged like tines on a fork, and put a bolt through the hole you want?

Love it!

Yes, except the red line passes through the tire patch and the front pivot. This is the line of action of the force acting at the rear tire patch.

Re: Ladder Bar Mod

The front of the ladder bar with a plate that rotates 180* but holds the hiem in the same location when rotated right? Wrong. It's the ladder bar that's kept in the same location. Aren't you still applying leverage at the same point the hiem is located to the chassis? The idea is to keep the ladder...

Re: Ladder Bar Mod

Billy, how would that leave the pinion angle unaffected? The ladder bars are simply solid extensions of the rear axle housing. As they're moved up and down, the pinion axis moves with them. This modification would allow the ladders to remain in "fixed" locations while different holes are selected a...

Ladder Bar Mod

Here's a mod for the ladder bar which allows convenient front hole changes and leaves the preload and pinion angle unaffected.

Re: Anti Roll bar questions

...it shows the body rolls a tad the right side. Look closely and you'll see that every RWD beam rear axle car is doing the same thing, to a greater or lesser extent. The driveshaft torque tends to unload the right rear and load the left rear. The reaction to that driveshaft torque, taken at the en...
