Slip Joint Body Mounts.

This chassis is based on a 12" from the center of the guide plate to the center bushings on the motor mount.
Length may vary, I have made some from 9 1/2" long to this length.

1. Slip Joint next to 12" ruler.

2. Side body mount on top of hinge, you can use round pin tubbing,
stack so you can use longer pins.

3. Front mount, pin tubing with hats on top and bottom.
This can also be done by inserting a small screw into the guide thread area.

4. Rear length for motor mount. 4" from under the back of the motor mount
to the hinge.

5. Close up of stack for side pin tubing mounts

6. Close up of front body mount.

7. Close up of the sliders/spring/torque bars, we based this
on the length of the motor box 4" long. So the overall length
is 8" for the sliders.

Once you have the chassis done then sit your body on the
chassis and mark and cut/trim off the bottom of the body
for the look you're trying to accomplish.
One tip on the chassis build is to make sure the chassis remains
as flat as possible, so it won't bind when you're running it.

Re: Slip Joint Body Mounts.

Bill give me a minute to show you other motor mounts I have used.

Now the reason for stacking the pin mounts is that you don't have to cut the pins, easier to find when you drop them.

I'll post pics of motor mounts in a few...

Re: Slip Joint Body Mounts.

Bill here are other motor mounts I've used.
Now on the right one it need a piece of tubing on the back so the motor mount will not distort and the bushings/bearings won't bind.
We did something like that on the World Tribute car.

Re: Slip Joint Body Mounts.

Bill here's the tongue I marked (exaggerated)  then I cut the excess.


Here's an underside picture when I use that cut down tongue, I add another piece of brass for the body mount and weight.

Side pins seen from under the whole dragster:

Your question about this part, I don't see where if you were to solder the pin tubing side to side instead of stack would make much difference, and like I post above, the uncut pin make it easier to work with.
