you will need two more axle bearings to prevent the "VW" syndrome on the rear tires.
They will tend to tilt inward at the top. been there.
I do remember the posts about the problem you had.

In my case, the frame is engineered differently, which eliminates that problem.
I have a cross member in the back that is doubled in the center, .....very strong.
Additional bracing yet to be installed, which will reduce/eliminate frame flex in that area.

Also notice that the hubs are quite substantial, and are up against the pillow block,
further reducing any chance of bending from normal driving conditions.



With the newly made, body bottom frame, that will bolt to the chassis frame,
adding additional strength, I can't fathom how I would ever have the same problem.

I may add an additional pillow block in the center area, for the drive,
but I'm leaving that, until I know how much room, I will have left after the body is finished.
I have allowed +/- 12" -18 " behind the seat, for batteries and drive components.
Seat bottom cavity design comes into play as well, thus additional room if needed.

Feels like I'm frying ๐Ÿ”ฅ...But I'm out here trying !

Oops !
And for 'your' chuckle of the day.
I guess the picture speaks for its self.



Body frame bottom attaching bolt holes drilled and home made bolts installed.
I have some threaded rod, so thought this would be a way to use it, and save money on bolts.
This being a low stress area, I thought why not.



The first of four side frame supports.

It's a probably a good thing, that I'm not working for a metal fab shop.
To look at what little I've accomplished all day, .... well you get the idea I'm sure.

Anyway, four done. Need two more for the back, plus a couple of angle pieces, to weld to the back corners.



Next is to finish welding these pieces.



Square up, and tack to the frame.
Then cut the three horizontal pieces.



What's nice about this 'body off' method, is that when it comes time to do panel work,
I can remove the frame and work on it, at angles that make it easier to apply the panels.

I am forward thinking, and will be using my 12 volt electric winch,
to assist with pulling the complete body, when it gets to be to big, for just me to handle.

Rear View Modification

  • Will go with flat back on bottom. (Access door will be easier to make)
  • Changed stop lights, to ones I had for the PVC car
  • Added flames received from Savarin
  • Moved license plate back down below.
  • Added some gold pin stripping
  • Back up lights are just a maybe. (May become reflectors)
Disclaimer
I reserve the right to change my mind, and alter the design and construction...on a whim !

Any idea how much weight you're up to so far?
***
The last time I weighed the various components, it was at, +/- 88 lbs.
Since then, I've only added the cowl, windshield and radiator.

I weighed the three pieces of 1 x 1 at about 25 lbs.
I've used maybe 1, for the cowl frame brace/s, and now the body bottom frame. So roughly 9 lbs more.
Add in about 10 lbs for the rear axle, hubs, pillow blocks @ +/- 13 lbs

So the total at this point, is around 110 lbs.
My goal has been to be under 200 lbs.

here is where you need to be next year
http://www.soapboxracer.com/
watch the video and get a good laugh while reading the rules
enter the streetrunner as an art vehicle
Way Coool !

I would absolutely do that, if I lived in that area.
Some of the RV group, are camping up that way as we speak.
Actually I have 3 days left to finish, and get up there....Nah, guess not.
Hmmmmm...maybe I'll make a trip north next year.
That looks like so much fun.
And some of those builds are wild, and some are real quality. I liked the #8, wooden body racer.

Thanks for thinking of me. Aren't you closer than I am? How about your entry.

Another blistering day.
Depending where you stand....

Covered patio..................................................99 F
Shop-both doors open/2 fans blowing........106 F
Outside the shop front in direct sun ...........112 F


Work awhile... cool off awhile...repeat.

Finished the four risers, for the body frame. But not without one problem.
One leg just didn't want to conform to the project, putting the frame out of square.
Had to partial cut, bend, weld, repeat. Took three tries to get it to finally settle on the measurement I needed.
Result is a not so pretty welding job on that one. Lucky, I suppose. It could have been worse.



As I'm using 1x1 tubing, when I cut the 45 degree angles, the measurement grows to 1 1/2".
So off to the metal supplier, early this morning. I was their first customer of the day.
Bought 20' of 1 1/2" tubing, (extra for later projects).



New tubing cut and tack welded in place.



Now that the easy part is nearly complete, it's time to put thought to how to frame the upper portion.
What compromises will I have to make, while still trying to maintain the look of the drawing.



I have a 2 1/2 " overhang, in the rear. Helps to break up the large amount of flat area.

My cozy little nook in the corner!
112? o_O HOLY COW! ๐Ÿ˜ฑ
The hottest day I've ever experienced in my life was 106!
That was a personal record I hope to never break!

Looks too crazy but fun

The wife's going visiting to Palm Springs, which is about 95 miles south of us.
Today's forecast for there is....are you sitting?. It's forecast for 117 degrees F (real feel (120)

I have actually made restaurant deliveries in Palm Springs @ 1 pm or so, and the temperature was around the 117 mark.
But that was back when I was younger and in better shape to take the heat.

I once measured the temperature in the back of my delivery trailer (Las Vegas)....@ 122 degrees. But the delivery had to be completed.

As Promised...I'll keep it clean

Taking time to clean up. I was beginning to feel 'deja vu', from the previous shop clutter.
I figured with all this heat, I might as well open up the shop and move the StreetRunner out for some fresh air.


FYI - Just in case.
Click on the photo. When it enlarges, click on it again, and it will enlarge even bigger.
At least it does on my computer.






A 'selfie' to give you an idea of size and perspective.
The top, of the top, (back half) should come to just about my eye level.

Windshield top brace tacked into place




Ground out a bit to much, Used a nail for filler.




Measuring the 1 x 1 1/2, to be used for the back wall of the body frame.



Need 44 " in the middle, then the curved corners, and then two legs at,... +/- 38 ".



Laying out where to cut the kerf's, for making the top curved corners, of the back frame.
Using a 5 1/4" Coffee Mate lid for sizing





My one main concern is the start and stopping point for the kerf's.
To little or to much it won't fit the 44" middle measurement.



After cutting the kerf's, I will bend the tubing, hoping to maintain a 'true curve'.
This tube is 1" less in diameter, so should nearly match the inside of the tubing I'm using.....I think ๐Ÿค”

Work a little - cool off a lot...Whew !

The next step.

Not wanting to 'step in it', I did some pre-cutting on some 1 x 2 furring strips.
I wanted to get an idea, of how far out to make the kerf cuts.


First attempt, but quickly learned the cuts weren't far enough through, and of course, the wood was dry.



Second try, much better.
And to my surprise the inside diameter is the 5 1/4".
If I counted correctly, there's 32 kerf cuts.
This practice piece broke soon after this photo was taken.




Jig, nailed to the floor, for after I've taken the plunge, and cut into my good steel tubing.
