Having “fun” with things

I was playing around with the nose piece last night because I’m the only thing moving after 0100 or so. This gives me more room to work with stuff like checking the fit of the nose compared with the body. Last night I mocked up the nose at full width just to see how it fit before modifications. The answer was “not good”. Seriously the full width nose is wider than the T-bucket body. I even took pictures.

The filler panel at full width flush to the side panels

And getting a good comparison to the body width.

See how much overhang there is compared to the firewall?

And the other side without moving the nose or body from the previous picture.

Still way too wide

And after moving things around to make room the nose as it would be in relation to the body.

The nose and body how they will be fore and aft of each other.

And the nose compared to the body from the other side.

This is how a car looks in my living room from the kitchen

And if you don’t have a car being built in your living room, why not? Do you just not have a car to build, or do you think cars should be built in uncomfortable spaces? Anywho, I’m doing some of the mockup in the living room because people have stacked a bunch of stuff in front of the door to the garage and also because my garage is where projects go to die of neglect and lack of parts. I have more parts coming for the Sprint-T as soon as they get off the boat from China, honest. So as long as I keep the project in the living room I keep the project going.

Also, I checked with the mock radiator and it almost drops through the space where the filler panel goes across the gap between the sides. On the car the sides are flush against the ends of the radiator so there will be a lot cut off the filler piece to keep the filler piece the right width to fit flush with the depressions in the sides. Also I know from the catalog the radiator filler cap is located on the driver’s (left) side of the car with both hoses on the passenger side. There is a slight possibility that I might have to make the center panel from the roll of HDPE plastic visible on the fireplace if the cut lines go through the decorative embossing on the filler piece. Edit: several hours of measuring later the amount I need to cut off is just outside the embossed decoration by less than 1/8” each side. The filler piece will fit flush to the nose sides with the radiator flush to the inside of the nose sides.

Now the black strip of tape is where the steering column goes inside the car, and also the driver’s centerline for mounting the seat which is also visible inside the car in about the place it fits with me in it. So, looking from the front in the third image you can kinda see where I would be if I was sitting in the car. My skinny butt fits with no problem but my shoulders are a major squeeze to fit still despite how much I have been beating on the rib restraints. I have already posted pictures of me in the seat post hammer-fest on the rib restraints, back a few weeks ago.

And with all the pictures I have used enough bandwidth for today so posting now.


I get lots of ideas on my walks

On today’s walk I ruminated in background on 2 problems: enough room for fuel tanks, and getting as much surface as possible for downforce including the windshield. Also I’m not a fan of the pinched cowl of the ’23-’25 model T, it offends my aesthetic and aerodynamic senses (which may be the same thing).

So, what to do? Well obviously blend the cowl into the windshield and the sides of the body, so that the widened firewall and hood sides flow the air smoothly down the sides of the body while the transition from the hood top to the windshield deflects the air up and forces the car down into the road, complementing this downforce generating nose .Downforce generating race nose

This is what I have to work with as shown with SAD (stick aided design). I literally duct-taped a thin stick to the side of the body to establish a smooth curve from the sides to the front axle past the firewall.
See how much gap there is at the firewall? Ugh!

Use your mind's eye to fill that space in and make it smooth.

Much easier to see how the front of the car would look from this angle.

This is how that nose looks on the kind of cars it was designed for.

My idea is in side profile to roll the hood over from the nose to just below the base of the windshield and make a smooth transition to the 30° angled windshield with the hood sides making an equally smooth transition to the side of the body like the stick taped to the side does, only all the way down to the frame, including the tuck-under at the bottom like the rest of the body. I’m still debating whether or not to put the little side fences on the hood to keep the air on it or to roll the top similar to the bottom or the top contour of the firewall.

This will look cool with the Monoposto seating in the center of the car. BTW that body mod will be 36″ wide at the original firewall and taper down to 29″ at the front axle, compared to the 27″ wide firewall it has now.

And it’s getting late again.
