Take cover again, I’m still thinking

Well it’s not as dangerous as some other times I was thinking, but ideas hazardous to the status quo might be promulgated. I’m still thinking about the Sprint-T, since about 52 years of cogitation hasn’t been enough to make it a reality. But I also think about other things than the Sprint-T, like getting Mrs. the Poet to come to bed with fewer clothes, making safer infrastructure for everyone, not just for cyclists, and making police less likely to kill unarmed people who are not criminals but just happen to be near where crimes happen.

The problem with that last one is some LEO think everyone in an area is a criminal because there are a lot of crimes there, when in truth only a few people are committing the crimes and most of the population is either uninvolved or a victim. And yes there are documented instances of crime victims assaulted and killed by the LEO summoned to take the report of the crime. That happens and police wonder why they can’t get cooperation from witnesses. Also there is the problem with racist cops who think every person of a certain shade or darker is a criminal just by existing. Cyclists sometimes get this treatment, because we are not in cars when we are on the street, but nowhere near as bad as POC get it around racist cops.

This problem actually has a solution, a simple one to implement in theory, but very hard to do in reality. Test every cop for racism and fire the ones who test positive. Like I said, hard to do in reality, unless we start at the top and work our way down to incoming recruits, because unless racists in the chain of command and the ones who decide on promotions are gone the bad apples who remain are going to once again ruin the whole barrel. So we have to get out the ones who ruin the whole bunch, then replace them with non-racists. And as we have seen, the racists are unlikely to go without a fight. The only way is to treat racism as a communicable disease, which in some ways it is.

Like cancer, the only way to stop this disease is to remove all traces of it from the body, which again brings us back to testing every officer and removing the ones who are racist or potentially racist. That one is going to be the sticking point, “Well, you aren’t displaying signs of overt racism, but you are showing signs of incipient racism.” In a way this is like those Sci-Fi movies where people are arrested for being capable of a particular crime, or thinking about a crime. This is a very slippery slope, so maybe put the ones who show signs of potential racism on some kind of permanent probation, or just put everybody on the same footing, a zero tolerance against racism policy. That would be the best thing, get rid of the overt racists immediately, then everyone else is on a one-strike racism policy.

OK, let’s spell it out and see where it takes us.
1. Test everyone from the commissioner on down for racism and fire everyone who tests positive for racism. All the overt racists are fired immediately, no recourse.
2. Everyone else is on a one strike probation, any displays of racist mentality and you’re on the street permanently barred from LEO in every jurisdiction.
3. This extends to all public interactions including social media. Belonging to racist Facebook groups, logging on to racist web sites, or making racist statements on Twitter will be enough to get fired and banned, unless such activity is needed to find people involved in crimes that might involve racism. I can see how some criminals might try to use this to plan crimes on platforms where LEO would otherwise be banned. This could be done by using people who are not allowed to otherwise interact with the public as LEO.

Yes, I have been thinking about this a lot.

Take cover, I’m thinking again

I’m thinking about the Sprint-T again, except I’m “thinking” with a bunch of catalogs and web pages open at various rear axle kits. I’m comparing prices and features for the Ford 9″ kits compared to the two quick change options. Now if budget was not a concern, like if I won the lottery, then my choice would be the 8″ ring gear quick change with the magnesium centersection polished in clear powdercoat, with magnesium bells and aluminum tubes, and the aluminum locker differential. This is the best balance of weight and performance. There are other options that are lighter, but at a cost to performance. There are options that have a slight potential for better performance, but at a major weight penalty.

And then there are the less expensive (can’t really call them “cheap”) options in the Ford 9″ housings. The main thing against these is because they are made from steel they weigh more, in some cases a lot more. But they are way less expensive, $1K±, compared to the $4K± of the “no budget” option in the first paragraph. This is a hybrid option, a race housing, hubs, and brakes with a “performance street” centersection, ring gear, and differential. Now for both of these the aluminum spool is lighter and cheaper than the differential, which means if I’m not seriously considering it there has to be a performance cost. Yes there is a loss in performance in the intended use with a spool, locking the rear wheels together makes the car understeer in tight turns that are part and parcel of autocross. And understeer is SLOW in autocross.

Now how much performance difference is there between the $4K rear axle, and the $1K rear axle? Maybe a few hundredths of a second, maybe nothing, depending on how smooth the track is. The rougher the track surface is, the better the $4K axle compares to the $1K one. And of course there’s the difference between a polished quickchange and a painted fabricated housing, the polished quickchange wins every time. But this isn’t a show car, it has a mission. Looks are important, but looks that don’t improve performance are expensive nonsense.

(Aside about that last word, it took forever to come up with “nonsense” because for some reason my brain wouldn’t go there, I got “ostentatious”, and “frippery”, but not “nonsense” until I started browsing thesauri online. I even knew the word started with the letter “n”, but going from “n” to “nonsense”… too far until I found the right thesaurus)

Anywho, there is another thing the $4K axle does is allow adjusting the final drive ratio from race to race and also for highway cruising between events. I mentioned this in a previous post, but it bears repeating that with the quick change I’m not stuck with a 4 or 5 speed overdrive automatic, I can get a 2 or 3 speed that might be lighter or cheaper. In other words if I spend an extra $3K± on the axle I can save a couple hundred on the transmission, or what’s really important, I can save maybe 150 pounds in the weight of the transmission. In actuality the weight savings are more like 60-70 pounds as Powerglides are about that much lighter than 4l60es unless I really need the 4l80e in which case then we are looking at over 100 pounds weight savings. Now 100 pounds less weight is a big chunk out of a car that will weigh less than a ton with driver and race fuel load. If I got my sums right, we are talking about under 1800 pounds on the starting line with driver and race fuel load using an aluminum block engine and PG transmission.

Also the $4K axle is maybe 20 pounds of unsprung weight lighter than the $1K axle. Now 20 pounds in a car that weighs less than a ton is not insignificant, but 20 pounds unsprung weight? That’s a bunch, particularly in a car that has as bad a sprung/unsprung ratio as the Sprint-T. And one of the things that has a major effect on handling on rough pavement is having a high sprung/unsprung ratio, unsprung weight is bad for keeping tires firmly in contact with the ground.

Foot problems are keeping me off the computer

Can’t take too long this time. In a nutshell I have been spending too much time sitting down, which makes my feet swell, which then makes my feet hurt, and so far the only relief I have found is lying down and elevating my feet.

And while I’m lying down, I think. It’s almost a reflex by now, the feet come up and the brain goes into gear. Since I’m lying down during the day I have light to read by and I bring a Speedway catalog with me. This at least keeps my mind from wandering off on tangents instead of solving problems that need solving for the least amount of money possible.

Something else I should mention is I won a $25 gift certificate to Speedwaymotors.com that had a limited lifespan, and I wanted a shift handle so I got the one in the link. The gift certificate covered all but $0.38 after the handle, shipping, and sales tax. So I have the style shift handle I always wanted for $0.38 out of my pocket.

And I just faceplanted in the keyboard again, so I’m calling an end to this post and time for bed. I guess I shoulda said I haven’t been sleeping well to go with the foot problems.

We don’t have any, but happy Pi day to everyone else!

Last week we were more than a little short buying groceries, so we left out the supplies for Pi(e) day, but I highly encourage everyone else to get theirs. [Billy]I like pie![/Billy] Really, Pi(e) day kinda snuck up on us this year. My favorite is cherry, but really there aren’t many things that can be legitimately called pie that I won’t eat, and like. The one exception to that is peach, because during a very bad period of my life that was the only kind of fruit I got, and it kinda leaves a bad taste in my mouth because of that. I associate everything peaches with that bad time, and just generally avoid them.

The weather is temporarily wonderful, mid-70s F but a bit breezy. The trees haven’t started shedding pollen yet, so I can still breathe sorta. The dust is a little bad and sometimes stops things up for a few minutes. It’s nice to see the sun again after about a week of cloudy to mostly cloudy skies. If I had a car waiting to get an engine pulled this would be the perfect weather to do it.

I have also been doing some more walking practice, disguised as “pacing” which is something I do when I’m thinking, pacing, I pace back and forth when I’m trying to pull an idea together. I’m trying to overcome the effects of spending too much time behind the computer by remodeling my stride to reduce the natural limp caused by the short leg. The limp causes me to burn up too much energy when I walk, leading to losing my balance and falling down. That is generally considered as “bad”. Or “not good”, if it isn’t actually considered “bad”.

Excuse me, speaking of “bad”, but there is a bad cat on my lap demanding attention from me. Back in a few.

Now to resume, I pace when I think and I’m not thinking at a keyboard. This is something that started back when my age was in single digits, so I don’t think I can break the habit any time soon, and even when I’m behind a keyboard I sometimes have to get up and pace to get my thoughts together on a subject. About the only thing that can keep me from pacing is a case of COL (Cat On Lap). Then the cat gets rubbed on while I think, something they can’t stand for less than 20 minutes.😸 But thinking, I do lots of thinking while I walk, putting things to the back of my mind and letting them run as background processes (yes, I’m a programmer from long ago, I learned how back when Fortran and Basic were still bleeding edge). Eventually an answer spits itself out, but I might be in another county by the time it happens. And the walking practice (remember walking practice?) helps make sure I don’t fall down while I’m pacing. I think of this as rehab, that I’m doing because I lost a lot of muscle mass behind the computer after the hip began keeping me off the bike. Well I have to build up endurance again so I can get around like I used to.

My soundtrack while I’m writing this is from my YTM app and it’s algorithm has decided I want a mix of electroswing, real ’30s, ’40s, and ’50s swing (mostly Duke Ellington and Benny Goodman) and classic rock, with some New Country. And nearly every song is something I either clicked “like” on or from an artist I had clicked “like” on, or “similar” to something I had liked. I like the old stuff from when I was a kid and before because I respect my music history.

Now go eat some pie.

No NASCAR race, and trying to rain here

No race to watch on the flat screen, and the weather is threatening so I can’t go for a walk. That means I have to post something here or go crazy. Going crazy is no fun, and I think you have figured out by now what choice I made.

On really good thing about the Pentastar for the Sprint-T is its extremely short length. There’s 43″ between the firewall and the centerline of the front axle on the Sprint-T and allowing for movement the steering linkage is 7″ behind that so 36″ from the firewall to the effective limit on the space. There’s a 3.5″ thick radiator to leave room for and a 9″ long steering box with a steering shaft that has to snake around the radiator, that goes between the radiator and the axle. Measuring the space from the part where the Pitman arm bolts to the rearmost part of the box as installed on the car and adding the working length of the Pitman arm (7″) I get another 12.5″ between the steering linkage and the radiator leaving just 23.5″ unless I put the radiator over the steering box like they do on the Speedway T-Bucket kit. Putting the radiator in the space between the front of the box and the steering linkage solves a lot of steering issues at the cost of raising the CofG slightly, but the radiator is only 19″ tall and there is literally 27″ to put it in. Mounting the steering linkage below the axle leaves even more room for the radiator in front of the steering box because the radiator can go over the linkage and still leave room for the axle to travel up and down. At this point in the design the radiator is a box that is 26″ wide by 19″ tall and 3.5″ thick that can be moved back and forth and up and down until room has been found for everything else. Anyway, the engine is a 20″ box in front of the firewall that leaves 16″ for everything else. And here you are reading in real time my thought processes as I build the front end of the car.

Recentering my thoughts, there is 16″ between the steering linkage and the front of the engine, the problem is the steering box and the radiator are trying to be in the same bit behind the axle. I could put the radiator on the right and the steering box on the left and have room for both. The steering box is 4.5″ from the mounting face to the right side of the box, 5.2″ total width, and I have 34″ of width to play with behind the axle, 17″ on either side of center. That means I could stuff a 28″ radiator in the car and still not hang out past the frame rails/4-bar if I put the radiator next to the steering box. If I choose to slide the radiator between the steering box and the steering linkage then I have more room for radiator width, but only just, and the radiator outlet would have to be passenger side to prevent interference. The widest radiator I can get a passenger side outlet at the places I’m looking is 31″ which is the inside to inside width of the bottom frame rails when I build to a width of 34″, serendipitous isn’t it?

And it’s time to check e-mail and get ready for bed.

Walking and thinking

As I take my daily walks I think about things. Politics, sexual fantasies, how to run a Cox TD .049 on FAI fuel (been working on that one for almost 30 years now and still haven’t solved it satisfactorily, the last attempt set the model airplane on fire and me, too), RPG characters… Anywho I was thinking about making the blog better. One thing I could do is write better posts, but alas I’m writing at the best of my ability as it is. Another thing I could do is change the graphics theme for the blog, but I wouldn’t want to do that without input from my current readers. So I will put a poll up and see what you want.
