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.

OK nobody will ride with me

I was getting used to the idea that Mrs. the Poet was not going to be riding in the Mid-Bucket, but I just found out that unless I took all of the bracing out of the halo my BFF would never be able to get in, and also that my grandson was not going to ride with me either (his mother remembers my driving her and friends in a 2-seat sports racer from before I quit driving back in the mid-’90s). So I’m going to go Monoposto with this car. That means I’m only putting in the one seat in the center of the car. This will make getting in and out much easier as the escape route will be unobstructed, there will be a place to sit on top of the cage and swing my legs over, and I can put my feet on either side of the seat instead of standing on the cushion.

Going Monoposto will make racing easier by letting me see both front wheels going past the cones, and make driving between events easier by putting the snacks and drinks in easy reach on each side of the seat. There will also be room for a day bag on either side of the seat down by the pedals with a cargo net to keep them from interfering with the pedals. It will also let me move the seat forward because I have the whole width of the firewall to use as a foot box all the way up to the firewall, about 26″ of inside width. Compared to the Sprint-T this is like having the whole state of TX to spread out in after living in RI.

This will also require some changes to the steering column and steering box mounting which then feeds back into changes in the gas tank. The steering box will have to go in the middle of the nose with an access trench through the top of the gas tank instead of down the side when the driver sits on the left. The trench is also needed to give the master cylinders a place to go on the firewall. The alternative to the trench is just restricting the height of the fuel tank to what clears the steering box and column.

And now it’s very late and I need to go to bed. I will think about the Mid-Bucket some more tomorrow when I go get a latte at my local Starbucks with the cards I have been generously donated and earn 150 bonus stars and a free drink.
