Eliminator Body Problem

[Mister B Racing]

I am building a new ladder style Eliminator. I drilled the axle holes straight using GoatBoy's drill jig. I narrowed the right front 1/16".

When I do a slow roll on my piece of track the car is dog tracking. The right front wheel rides along the rail, but the left rear is also riding along the rail.

Did I narrow the right front of the body too much? Axle holes missed aligned?

I'll probably scrap this body but before I do I was just wondering if there was anything I can do to take the dog tracking out of it.

Thanks,

These are just ideas, since I don't have hands-on experience with Eliminator cars:

Have you done any diagnostics on the rears? Tried putting drill bits or pin gages into the axle holes and checking for alignment and perpendicularity with the body?

Have you tried swapping the axles in the rear to see if anything changes on the slow roll? Swapping the wheels?

Yep, you narrowed it to much. You can try a thicker washer on the front, that's about it.

Did you have it weighted and steer set when you slow rolled? That can change it.

@Kinser - No the car was not weighted, just the body and three wheels. I will weight it and and do the slow roll again and see what happens. I will also add a second washer to the front too and see what happens.

In the next couple of days, I will let you guys know if your suggestions have helped.

Thanks for the tips!

I don't think that 1/16" is enough to make the LR wheel make contact. I have narrowed 3/16" and still not made contact.
I wouldn't scrap the body. Like Kinser said, you can run a thicker washer up front. Will be interesting if the slow roll is drastically different once the car is weighted.

On one car that I narrowed too much, I glued a 1/32" strip of plywood to the DFW side and just popped the drill through from the opposite side.

Here is the Eliminator body that I am having the problem with.

My best guess would be that you put weight in it and it'll change.

3/16"? That's a lot!

I've also added wood. It was easier than routing and drilling another body.

You can take bent out of the DOM axle also, that will move the left rear over.

That's a beauty! I hope you get it running how you would like!

Steve that is a great looking body! I also agree with all the tips that have been provided here. Spacing out the DFW or taking some bend out of the DFW axle should get that left rear off the rail and into good running form again.
