OK first things first and then PICTURES! I did what I said I would do, cut the floor for the scale mockup of the TGS2. When I got done with that I couldn’t get the brain to shut down, even with chemical assistance, until after 0800. Then I woke up at 1100. 1200, and 1400 when I got up and said the heck with it. So if this seems a little less coherent than usual you can blame lack of sleep. Or something.
So anyway work. I laid out and cut the floor for the scale mockup TGS2 last night, measuring to the thousandth, marking and cutting to the hundredth of an inch. In scale that’s measuring to the 1/32″ and cutting to the 1/4″. Here is what it looked like after laying out the front wheel cutouts.
I decided to go with a straight leading edge on the floor for more downforce, even though the curved cutout looked better. It turns out the curved cutouts induced attached vortices that reduced airflow under the floor which in turn reduced downforce. I may cut back the strakes between the nose and the rest of the floor for the same reason, they may induce an attached vortex. Or they may prevent detached flow under the floor which would seriously reduce downforce. That’s why we make mockups.
Here’s the rear wheel cutouts.
And the cut version.
And with the bucket from the Mini Sprint-T resting on the floor.
You can see why I can’t use the Mini Sprint-T bucket for the TGS2 mockup, I already installed the windshield.
And the view from behind.
I expect this to be a popular view of the car.
And for perspective with one of the kit wheels and the tires I’m not using on the Mini Sprint-T.
Sticking way out there because wrong width. In case you were wondering I was going to build the old school hot rod version of the kit with these tires.
Showing the position of the outer edge of the tire.
And how close the inner edge is supposed to be. This is still much further out than most T-buckets run their rear tires. Some are so close the inside sidewall rubs the body in hard turns.
The pictures with the tires showed the approximate ground clearance when racing, thanks to the stock Model T tires in the kit. Fortunately 4 pennies stacked is the correct thickness to portray the street clearance.
Unfortunately I don’t have a tripod to show exactly how much higher this is.
And I have put about 4 hours in on this, time to put it (and me?) to bed.
