Several people have placed their bite bar through the motor box, I think most people have found the best location is just before the motor.

Once upon a time, a long time ago and forever … I looked up to the Chassis Gods.
In 1965 all that could be done with a Weller Gun that a buddy had was to burn myself, the table and endbells too. Throbbing fingers and toxic shock sinus and brass stuck together at all the wrong angles thinking .. "How do those teenager kids do that"? ... There was no trainer … I was 9 years old.
So today’s special is a highly tunable, two rail, torsion pan Retro Stock Car designed to be used as an “Any Track car” as a first (and only for now) 4.5” car.
Can’t fool me … you guys know what you’re looking at and how this stuff works. I’ll start at the front.
Shown with the car in photo #1 are the six tuning springs.
The Front:
4 wires for inserting into the pin tubes at the rear of the pan.
This sets the front ride height, adds cross weight when using the long spring inserted into the inner angled pin tube at the back of the pan.
The 2 short wires do not add cross weight but maintain spring pressure on the front axle keeping the load on the spring and just off the shimmed ride height setting screws. These act as the ‘Bump Stops’ keeping the pre-set ride height when the spring load is loaded.
These four straight wire springs and is designed for a “Soft Spring “Cross Jacking” set-up for flat and intermediate type tracks.
The 2 ‘Paperclip’ spring wires fit in the pin tubes that are also supporting the front axle uprights. These are for the “Stiff Spring” set-up on high speed banked tracks. The long springs can be used also to add some cross for hard hitting on steeper banks.
There are 2 springs not shown that mount like the paperclip fronts but these hold the axle up on the bump stops.
The middle:
It really is a fixed 2 rail car with 2 floating rails in a box that are tunable for “Forward and Side Bite”.
A rail in a box … in a box …. Or not … long or short … one side or both.
The back:
Some good stuff going on back here starting with a CR motor bracket. Drilled for torsion pan limiters and then braced heavy with box tubing for the floating rails and square “Bite Boxes”. Add .062 lower slight V and an.047 lightweight upper V braces. The upper is formed at the top and slotted into the tube holders. Vertical brass tubing provides a lot of support to the axle tube. These also are there for locking down the ‘Bite Boxes’ and provide a location for a body support upright if needed.
The concept has rattled around in my head for about a year and 6 months of it on (and off) the RetroPro jig. I am slow but everything was thought through before building. My building skills are unrefined and need much more practice like cutting two pieces of wire the same length. . . lol
Even with the recycled pan ... If it was sanded, filed, tumbled and polished it sure could be pretty too.

It's nice to see someone using the adjustable front wheel supports.
Sales on them have been less than stellar.
While a few guys like Jay Guard have constructed chassis with screws for various adjustments, I'm sort of surprised more
haven't utilized them.
I predict in the semi-near future, you'll see more of it.
Just like the Z-rail chassis, you just need a few in the winner's circle for other guys to follow suit.

First, I needed another Can-Am chassis. Until I built this one, I only had 1 chassis that was raceable. Once I finished this chassis, I was very happy 'cause I then had TWO Can-Am chassis'! It may be obvious from the pics, but it wasn't to me when I built it.... this is a pretty stiff chassis and turns out it's only decent on a King track. It was pretty heavy too, so I drilled the crap out of it. I'm even going to lighten it just a bit more in the nose; that's .062" brass up there, ya know! At LEAST I now had a 2nd chassis to run if I damaged the other one.

Looks good Tex, Are you locking down the bar with the screws? Like full float or no movement?

Kind of reminds me of a Pablo-Flex chassis from a couple years ago
Nice clean build Pablo,
Rail in a box? Interesting hinge location ... how does it handle?

Bob, the Pablo-Flex chassis is in the hands of Greg Gilbert, and he does real well with it. It seems to like swoopy hi speed tracks.

Cool, I know you're good . . . you get to build for the legends!
BTW: who doesn't like swoopy hi speed tracks ?....
