Not much to say today. Mrs. the Poet’s incision from her back surgery is healing nicely and she may start PT as soon as they start allowing home visits by the Physical Therapists, which are stopped because of the COVID19 pandemic to prevent transferring the virus to people who are medically fragile. As the headline stated my allergies are bad this year, this was the first time my eyelids were so swollen that one split over next to the corner. Other than that and some pains in the reconstructed hip I’m doing good. I’m not sure but I think the pain in the hip has something to do with sleeping 14 hours on Wednesday followed by much walking around Thursday.
Speaking of running around on Thursday, on the way home the bus took me through the local large shopping area, what was built to replace the promised mall but is only several large retailers in close proximity and sharing parking lots. Anywho except for the places selling food with drive-throughs the place was a ghost town with literal acres of empty parking lots. Local retail has been clobbered by the shelter in place order for Dallas County, and will take years to recover if it ever recovers.
On the Sprint-T I have been designing a fairing for the front tires that also houses the headlights and supports the front edge of the front fenders. It’s simple, a half cylinder to split the air in front of the tire and a tapered rear fairing at the rear edge of the tire, with a flat or slightly curved top, all made from HDPE sheet. I checked TX regulations and purchased some headlights that are legal, LED replacements for the 4656 sealed beam headlight. The have both low and high beam and are above minimum and below maximum lumens so are legal in TX, about $40 shipped with tax for a set of 4.
Now to install them on my car I need to run by a junkyard when they open back up and get a headlight assembly for one side of a quad rectangular headlight car, because I only need one per side. I need to get the plate the buckets mount on, the adjusting screws and springs, the buckets, and the bezels that retain the headlights to the buckets. I just need to mount the backing plate to the vertical piece at the back of the half cylinder and between the side pieces of the fender in a place that clears the tire at full bump and full lock in both left and right. Nothing to it. I just need to make a drawing of the tire at full lock in both directions and on top of that drawing put the headlight at the height it would be in relation to the tire at full bump which is about 1.5″ higher than normal ride height. I know the vertical part of the front fender fairing will be a little forward of where the front of the tire will be at the straight ahead position so that it will clear the tire at full lock. I have been thinking about making this part slightly curved for more clearance at lock, and more rigidity. This is also why I was thinking about curving the top part of the fender, to make it more rigid in use.
Now something else I have been thinking about is making the front fenders quick-release for when I’m racing, because light weight is way more important than reduced drag in the kind of racing I’m building this car for. The courses will never allow anything even close to top speed where drag reduction is more important, all of the sanctioning bodies require top speeds on course be no more than normal street or highway speed and one body requires no more than 30 MPH. So especially for that one sanctioning body, light weight is more important than drag reduction. On the street drag reduction is less important than light weight, on the highway light weight is less important than drag reduction but I need fenders and headlights either way. Now for this kind of racing being able to see my front tires is a slight advantage for placing my car on the quickest line, maybe a half second on a 1 minute course. That is a good enough reason to make the front fenders and headlights removable. But I’m still cogitating about how to do that and not change headlight aim when removing and replacing the fenders. More thought is required and maybe wasting some raw stock on different prototypes to test for rigidity and repeatability when removing and replacing.
