I keep wanting to add “and the Feed” to headlines like that, except I don’t do that any more. Any bike wrecks I see online are incidental these days, instead of being the result of a deliberate search.
Anywho I gained 5 pounds since Mrs. the Poet’s return, and we may have figured out why I’ve had high blood pressure since I was a kid. Way back in 2002 I had to get my BP under control for an operation, so calcium channel blockers were prescribed and they did what can only be described as a “bang up job”. Also one of the identifying characteristics for my other condition is a high blood calcium reading that leads to the extreme bone density, which in my case is something between “concrete bridge support” and “actual rock”. I think I might have mentioned getting tested for this by a guy studying the condition, and that one of the things tested for was blood calcium level and that mine was in the range that defined the condition but he didn’t tell me the exact reading. Which is typical of doctors they run tests and say it indicates this or that but they never give me the actual numbers unless I press them on the subject.
So, next trip I’m going to bring up the subject with the Lab Rat Keeper and see if we might get some other kind of treatment for my hypertension, to go with the current diuretic. The guy studying the super thing said that diuretics are part of the standard treatment for the condition to prevent kidney stones. I need to bring the blood calcium levels and calcium channel blockers up because this could be a key to why I still have high blood pressure.
As for the other “stuff” I found out that the 4.8l crank and rods in 6.0l and larger LS blocks is popular for building higher RPM middle-displacement engines to run on 87 octane. The theory is the longer dwell at TDC gets a more complete burn and more expansion of the burned gasses with less spark advance to heat up the combustion chamber and cause detonation or pre-ignition, and has been proven to generate more power per pound of fuel burned. That’s a fuel economy thing, moving the car the same speed with less fuel, but it also is a performance thing. I guess it also would work with a standard stroke LS (3.622″) with shorter piston compression height and longer rods, but the effect is amplified with the 3.26″ stroke and 6.275″ rods from the 4.8l engine because there is a limit to how short a compression height you can get imposed by the separation between the second ring and the oil control ring on the piston. The oil ring can intersect the piston pin location, but that is as high as you can go and still have a functional engine with current piston ring technology. Also the increased rod ratio (rod length/stroke) of 1.932 for the 4.8l crank and rods means significantly less piston wear from side loads regardless of the RPM range and still allows the use of standard pistons for the size block chosen. As a point of comparison the 383 SBC has a rod ratio of 1.52 with stock SBC rods, and the 350 SBC has a rod ratio of 1.638. This is a substantial improvement for the 4.8l crank and rods. I’ll have to do “something” to bring the compression ratio back up after installing the 4.8l crank and rods reduces the displacement of the cylinder compared to the original crank and rods. “Something” in this case is reducing the combustion chamber volume by the same ratio as the change in displacement from the 3.622″ crank to the 3.26″ or about 11%. That’s a major change in volume, for the smallest factory LS head that would be more than 6cc (6.829). That’s a large cut to the head combined with a thin head gasket to get the combustion volume to the point that the same place it was before the crank change. I guess I can live with the 11.3:1 with the stock heads and the 0.027″ compressed height Cometic composite (not MLS) head gasket.
Well that’s enough rambling about a fantasy engine, time to put this post to bed and eat the dinner Mrs. the Poet has been working on. Oh yeah they just announced that the total number of twisters that hit the area on Sunday was 10 as they found another damage track in an unpopulated part of the area.
I forgot the picture of the stuff I got for the Sprint-T, and I forgot to tell you what I weighed after fasting at the Lab Rat Keeper. And other things as well.
First things first, this is a picture of the stuff I got combined with stuff I already had so you can see how it goes together.
These Heim Joints have 3/8” holes and 5/8” shanks to fit the brackets and the links available. The brackets obviously have the holes and can’t be drilled larger without weakening them to the point that a minor wreck would tear the holes, requiring major repairs to the axle. So what I have planned is making the weak link where the links meet the frame. The plan is to use cheap, fragile aluminum body Heim joints that break at impact loads but still strong and rigid enough to not flex in regular use. And the next weak link is the links themselves, internally threaded aluminum tubes, that bend under impact loads but like the frame mount Heim joints don’t flex during normal operation. The intent is to absorb impacts by bending or breaking cheap parts that are easy to replace without damaging expensive parts that are difficult to replace, or have a long lead time to replace like the 4 week lead time for the front axle.
Now, my weight at Wednesday’s visit to the Lab Rat Keeper showed just how much I have for breakfast, particularly how much coffee. I weighed 211 pounds (95.7 kg) the previous visit, but only 208 (94.3 kg) this visit. My normal breakfast before a visit is a package of PopTarts and a “my cup” (750 ml) of coffee, and I usually have a light meal right before bed at about 0300. I have measured the capacity of this “cup” several times and the only way it reaches the manufacturer’s 1 quart rating is to leave the lid off and fill it to the brim, but measuring to the inside top of the lid gets 750 ml. But anyway no 0300 meal and no breakfast has me at 208 pounds.
Also there were races today, but if you were interested in that you would either have watched them yourself, or accessed a sports site to find out who won. I will say that the semi-local IndyCar race Will Power broke while leading. 🙁
I have been away from the house almost every day this week doing something or another, or recovering from being away from the house. I have things to write about but either no time or energy to write about them. Well I’m still low on the energy but I have the time so here goes.
Monday I deposited a check and made a trip to the hardware to get supplies to do a kludge to fix the bathroom, then used the supplies to do the kludge. We have an ancient (1984 or so vintage) bathroom faucet that can’t be fixed because parts to fix aren’t available, and has been installed so long that new feed lines have to be made to install a new faucet. I can change out the faucet if the feed line fittings are still intact, but these fittings are so old I don’t think they will survive removing the old faucet, so a kludge to prevent the leak from flooding the vanity was to corral the leak so it goes down the drain when the faucet is used instead of all over the vanity.
Tuesday was getting transportation to go hang with my friend in TN before he moves his family to DC to rejoin his wife who works for the Corps of Engineers as a civilian employee. She used to work in Nashville, but got a big promotion and raise to work in DC on more national projects than her position in Nashville. Late June everybody is moving to DC to live, so their kid doesn’t have to change schools in the middle of a school year. So before that move we are going to have one last visit to TN, and I spent most of the day pricing options and setting up transportation. So too busy to write.
Wednesday I went to the Lab Rat Keeper to participate in more Basic Research (yay!). Someone has discovered a New Protein Marker that in animal testing showed up when hypertension was caused by a physical process but not when it was a stress reaction or other externally-instigated reaction. This test was to determine if that marker was present in humans, and could result in people getting a lot less medication for high blood pressure that they don’t really need because they have White Coat reaction that temporarily raises their blood pressure or other external things. This means less chance of getting hypotension and the problems that go with it, like fainting and excessive urination…
Yesterday was a fiasco as I missed the bus for the appointment to see if I can get free Lasik and had to reschedule for next week. And one thing cascaded into another so to salvage something out of the day I used a coupon from Whataburger to get Mrs. the Poet a free Mushroom Swiss burger for dinner. I got the Bacon Cheeseburger meal, and then because it was quicker than waiting for the bus I walked home from the Whataburger, over a mile. When I was younger, like 3 years ago younger, a mile one way wasn’t a problem, but things have not gone well on the joint pain front and walking a mile is significantly more difficult now, as in the recovery period is almost as long as the walk. And again, when everything was done I did not feel like writing, at all.
Which brings me to today, where I have time, and sorta kinda have energy to write. And there you have another slice of my life. Thrilling, wasn’t it?
Well, today’s appointment was rescheduled again, this time because a massive thunderstorm with 60+MPH straightline wind gusts and street flooding took out the power at the Lab Rat Keeper’s office, leaving them with no phones, no lights, no lab equipment, no AC/heat… The appointment has been rescheduled for next week. This makes over 30 days since the original appointment back in February, about 6 weeks if the rescheduled appointment works out. Not quite as arduous as Sisyphus’ eternally rolling a stone up a hill, but just as frustrating.
Nothing else to report on as after they called I went back to bed, then read some comics after I got up the second time. Also, still thinking about building the Sprint-T, but can’t even do anything about thinking about the Sprint-T because no $ for parts or even thinking about parts. So, if you have a front-engine RWD vehicle with an automatic transmission that runs and shifts that is otherwise on its last legs, I can give it a home. I’ll pull the engine, transmission, and possibly the rear axle, do what it takes to make them work in another vehicle and then send the hulk to a recycler with a flower taped to it to mourn its passing.😔 I’ll split whatever the recycler pays after towing. So, take a dangerous vehicle off the road, give life to the Sprint-T, get a few bucks, and everybody wins!
There was a problem with scheduling at the Lab Rat Keeper so I’m here and not there today. I have a new appointment same day and time next week, and this will be a fasting draw, meaning I get up and take my pill with water and don’t have anything to eat until after noon and nothing to eat after midnight the day before. Now ordinarily this would not be a problem but I eat a snack about 0200 so that I’m not famished as a bear in Spring when I get up. So I will be consciously monitoring my mood so as to not to bite anyone’s head off.
We are having game tomorrow instead of Sunday because there were multiple schedule conflicts on Sunday and everyone can make it on Thursday. And after I post this I’m going to get my toes done because they need it something awful because it has been a few months since the last time. Seriously they are starting to hurt again because the nails are that long. So another shower to make sure I smell nice after lunch and off to the nail spa for shorter toenails.
I have a visit to the Lab Rat Keeper the day before Valentine’s day for a quick blood draw and BP check, and maybe a hamberder or something at one of the several fast food joints in the area. The covfefe house is closed, but despite having a large chunk of the building burned away the Mexican chicken place almost across the street from the office is still serving food. I’ve never been there, it might be a good time to try it out.
On the Sprint-T and Mini Sprint-T front, there has been a minor change in the design around the main cage. Basically the upper frame rail is now running in segments inside the hoops instead of over the corner after I did another stress analysis that showed too much bending stress on the hoop with the rails running outside the bends and the diagonal braces welded to the top and sides through bends and/or bent gussets. What I had before was the rails welded to plate brackets on both sides of the hoops in line with the horizontal and vertical legs of the hoop. What I have now is the rail welded to the top of the hoops right at the end of the bend and also where the diagonal welds to the hoop, kinda sorta. Actually the diagonals have the same size bends as the hoops so the bends line up, and using the same bend to make the connection to the vertical leg as a gusset to carry those loads directly into both legs of the hoop without imposing bending loads that have to be carried through the bend in the hoop. That’s because the bend is the weakest part of the hoop, but by using gussets and routing loads away from the bend it can be made to not fail in a wreck.
On the down side dividing the upper rail into segments and welding it to the top hoop next to the bend slightly reduces the d4 effect for torsional rigidity, because this change moves the top rails about 9″ closer together side-to-side. Instead of being 48″ apart they will be 39″ apart across the top of the cage. That’s a 56% reduction in stiffness in that plane, but that plane only contributes 25% of the overall torsional resistance of the frame. Basically this keeps both of the side planes that resist forces up and down of the total twist vector at the same stiffness, and has no effect on the bottom plane at all so even though that one plane is reduced 56% the total stiffness is only reduced by about 13% total in torsion. Noticeable but not critical. Second downside is the reduction in the access hole in the top of the cage by 4.5″ when it was already barely wide enough to get in and out without twisting sideways. So guess what I get to do getting in and out of the car?
In things that have nothing to do with me or the Sprint-T personally, the squirrel apparently made its escape prior to the arrival of the people we paid almost $400 to remove it. Also Mrs. the Poet has fallen and bruised her backside, enough that she makes involuntary noises about every other step, sometimes very loud noises accompanied by rude words. I’m not so bothered by the rude words as I am the volume used and the frequency. If her butt hurts she needs to lie down and let me take care of her instead of running around complaining I’m not doing anything for her.
The good news is I weighed in at 210 again, and my BP is slightly high but still “under control”. The bad news is while they are scrambling for a drug that can replace Valsartan, it will be more than a year before human trials can begin. This is what happens when you put too many of your eggs in one basket, and somebody drops the basket. In this case the basket was a Chinese pharmacy company with questionable safety practices that managed to corner almost 80% of the world market for Valsartan, and dropping the basket was not properly controlling the process and allowing known human carcinogens to get made as part of the drug. Now there are several ways this could happen, but the most likely would be contaminated feedstocks, the chemicals they use to make the drug. My guess is that more than one was contaminated, and probably with chemicals that individually are not problems so they were allowed through, which then reacted with each other and the actual chemicals that were supposed to be there to form the carcinogen(s). But then again I’m just a technical writer with a background in chemistry and making explosives from “indigenous materials” for my first enlistment, not a trained chemist.
In other news, it wasn’t beastly hot today. I don’t think we even broke 90°F thanks to a cold front and heavy morning cloud cover. And I can’t remember the last time we had a morning low that close to 60. And that was a very noisy cold front that came through at 0500 and woke me up, so I’m trying to not faceplant into the keyboard right now and mostly succeeding. And when I don’t it isn’t a real faceplant, more of “my nose brushes the keyboard and I wake up with a start” so my laptop doesn’t take any more damage than it already has.
It’s really annoying to need to get my toes done, because I can’t see it before I feel it. The first I know my toes need doing is when I feel the pain of the nail catching the inside of my shoe. Ultimately I need to get slightly larger shoes before too long, but these shoes are not wearing out as fast as the cheap shoes I used to buy. The wear is literally proportional to how much I spent on them, the almost $60 per pair shoes are showing about twice the longevity of the $30 shoes.
My Sweatcoin mining is proceeding apace. I have more than 40 Sweatcoins in my “wallet”, currently valued at $0.05 each. Yeah that is “not rich” by any measure, but I got out of the house and I did get something out of it. The only downside is as explained in the first paragraph, if my shoes don’t fit right there is a price that has to be paid in pain.
I have a trip to the Lab Rat Keeper tomorrow, so no post. I have to get up about 0700 so I can eat, get caffeinated, and shower and dress and get out the door. I finally get to use my Reduced Fare ID. Sorry I don’t have more to write about, but nothing much has been going on around Casa de El Poeta. I have been following the Uber wreck with a cyclist in AZ, but they still haven’t decided if the person was riding the bike or pushing it, or even which side of the street she came from. The only upside is because this was a test vehicle everything was supposed to be recorded and preserved showing why an autonomous vehicle was unable to avoid an adult cyclist or pedestrian. Obviously corners have been cut because AV are supposed to be able to easily avoid people in the street, in fact the Google implementation can be stymied by a cyclist doing a track stand at a stop sign because of the slight movements made to remain upright. So the evidence points to some non-action on the hazard-identifying function for small vehicles in adjoining lanes.
And since I need to get up early tomorrow, and I still need to do my e-mail, I’m done with this post now.
