No game this week, again

Family tragedy struck one of the players in our group as her father-in-law died a few days before game. Also, I have been beset by allergies that have really upset my sleep cycle as my sleep aid is just a double-strength allergy pill, minus the buffers. So, instead of putting me to sleep, it just clears up my nose and eyes for the night until it wears off. I was awake after 0700 this morning even though I put myself to bed by 0500.

I ended up sleeping through most of the race today, but I did manage to tune in for the last 20 or so laps, watching Kevin Harvick chase Joey Logano and almost catch him until Joey used dirty air or lapped cars to slow him down to keep Harvick from passing. It was a master class on how to defend a lead in a Cup race. I’m not a fan of Logano, but I do give credit where credit is due, and Joey drove his butt off keeping Harvick at bay.

No progress has been made in the Sprint-T redesign. I have all the major pieces in place, and until I can get some raw stock, which is really hard to come by these days because of the one-two punch of tariffs and COVID19, I really can’t build anything. Even in the case that I was able to find the raw stock, the combination of the stock thickness and having tools sized for bicycle building and not hot rods leaves me with stock with the dimensions laid out but no way to cut and drill to the sizes needed and make the part. It is frustrating to have drills that won’t handle drill bits over 3/8″ when the smallest hole is just under 1/2″ and the big hole is 9/16″ to allow for the thread depth of the bolts and the tap that cuts the thread so those bolts can screw into the part. It’s a combination of lack of power in the motors and the chucks just not being physically big enough to hold the larger drill bits. And for my cutting tools the 1/4″ thickness is pushing the limits of the equipment because when I bought the tools years ago when I was building bicycles 3mm (1/8″) steel or 5mm aluminum was the heaviest stock I was going to ever cut. Building hot rods wasn’t even on my mind. Let’s just say I was in a bit of a state over cars since someone tried to kill me with one, actually several someones tried several times with varying degrees of success, but nobody actually killed me thank [$DEITY]. So for most of this century since the wreck, I have had varying degrees of antipathy about cars.

OK, let me take inventory of tools, parts and raw stock that I need to complete the Sprint-T. I need something that can make square or mitered cuts in stock at least 1/4″ thick in mild or chrome-moly steel. I need a drill press that can handle 3/4″ holes in the 1/4″ steels, and up to 1/2″ thick in aluminum. I need a welder that will weld over 1/4″ thick steel, and that will weld aluminum. I mean I can use oxy-hydrogen to weld aluminum now, but that is a very tricky technique for someone with cataracts to work with, and I’m not sure that it didn’t contribute to giving me cataracts in the first place. Anyway, after the tools I need lots of raw stock, DOM or chrome-moly seamless tubing in 1.5″ diameter and 0.120″ (7 sticks) and 0.060″ (5 sticks) wall thickness, some 1.25″ diameter DOM and 0.120″ (2 sticks) wall for making the tie rod, drag link, panhard rod, and the torque arm. Also needed is a metric buttload of hardware to connect things that have to be able to move in relation to other things, in various sizes from 3/4″ fine thread (pretty big) to 4-40 (tee-niny).

It’s getting late, so I’m wishing you a good night and pleasant dreams.

Well, that was quite a race!

It didn’t turn out quite the way I wanted it to, but wow! what a race on the Roval at Charlotte. It was raining at the start, then stopped, then eventually got sunny leading to a track that was tricky to drive every lap. And tricky to drive leads to exciting racing.

I’m not going to lie, my guys didn’t win, and they were in a “points below the cutoff line in a cutoff race” situation. Those were Clint Bowyer, who is retiring at the end of the season, and Kyle Busch the reigning champ. Clint I just wanted to see have a shot at the championship in his last season, because he’s always been a good driver and also a good person from what I can tell. Kyle just didn’t get a fair chance this year because of the rules changes caused by the Stupid Virus. Kyle’s style is to make the car perfect in practice, and there was no practice this season after the Stupid Virus. My problem was they can’t both win, and the only way for both to go to the next round was for the 88 car to blow the engine on the pace lap or similar and Clint and Kyle to finish 1-2 in that order. Did I mention I don’t particularly like the driver of the 88?

In other news, I’m still evolving the mount for the steering box and changing the front bulkhead in the process. I decided the car would be faster if I made the bellypan all the way across the car to the outside edge of the fender, which meant I needed to do something to support the leading edge around the front tires. Since the front tires would get pretty close to going parallel to the front axle, I subtracted the diameter of the street tires from the axle width to come up with 31″ clearance at full lock, which just happens to be the same width as the radiator. Which means the extension of the front frame rail really needs to be on both sides of the car, making the bottom of the front bulkhead way wider than the original design of a point at the bottom intersecting the main frame rails also coming to a point.

The new bulkhead is radically different. Where there was a straight tube across the top from one shock mount to the other with a tube from each shock mount to the center V-point and some internal bracing to prevent flex, the new design has a straight bottom tube that runs across the intersection of the main frame rails to the rail extensions spaced 31″ across outside to outside, and a tube from that intersection to the shock mounts and another horizontal tube across to support the downforce-generating nosepiece from underneath so it doesn’t need to be cut and fitted around the bulkhead, and is way easier to install and remove for maintaining the steering, and has the secondary effect of making as much downforce as the nosepiece can make. This upper tube will be 31″ wide and the vertical from the extension to the upper tube will also act as the mount for the steering box. And then there will be another tube from that intersection to the shock mount, triangulating the mount, and a tube from the intersection of the upper bar and the vertical from the extension to the point where the main frame rails intersect with each other and the front bulkhead to triangulate the steering box mount and the place where the load from the shock mounts feeds into.

I really need to draw this out and show what I’m writing about, because while there are a lot of words, there are not a lot of tubes involved, only 10 total in the front bulkhead, and just 6 more that intersect it. Which sounds super complicated, but not so much when I visualize it. I just wish my hands worked better and I had the tools and the paper to draw it like I see it. But if wishes were horses we would all ride everywhere. And that is a saying that predates bicycles it’s so old.

And I didn’t finish my statement about supporting the front of the bellypan. Well I need to establish the swept curve of the tires moving to lock between straight ahead and the tire parallel to the axle, which is a fancy way to say I need to trace out the curve of the outer corner of the tire tread, all the way until the tire is at right angles to straight ahead, and then copy that curve on a tube roller (which I still have from building bicycles) on a chunk of light 1.5″ tube. That will be the leading edge of the bellypan from behind the tire to the frame.

I will have other tubes on the outside edge to support the bellypan all the way to the edge so I can use it as a step to get in the car, and so that any downforce it generates goes all the way to the suspension like good ground effects. I already know that there will only be a tiny amount of downforce even on the freeway, but I want every ounce I can get.

I was also thinking about the A-Mod car because I had an allergy attack that made me sleepy so I went to bed, but then wouldn’t let me sleep. So I stared at the shadows on the ceiling and planned the Next-To-No-Car-There-Car. Basically just enough frame and body to hold a body to the right of center with outriggers to mount coilovers and the bits to hold the left side of the suspension in place, and a big empty space to be filled with a motorcycle engine that gets moved from side to side to balance the body in the part of the car designed to carry the body. That’s about as far as I can get without drawing tools and paper.

So, that’s what happens when I have too much time to think, and there’s a really good race on the next morning.
