I’m melting, melting, what a world…

Heat indexes have been off the charts lately, from what I can tell. I haven’t been able to go for my walks so I have been spending most of the time indoors and hardly check the weather, but it’s 86°F in my office as I type this with the AC going. So it can’t be anything but hot outside. But just FYI my phone says it is currently 98°F outside. At 1855. So by deduction it must have been over 100 at some point today, say like between 1400 and 1500. ETA the 2200 news weather report had a 100° high temperature. And the urban heat island effect keeps the nighttime temperatures up, too. And this is where today’s headline came from YouTube

I’m not happy with the way the floor came out for two reasons. Number one is I forgot to include the front support for the front fenders, and 2) I made the rear cutouts too wide, as shown in the pictures. Seriously I left enough room for a 16″ wide tire and the widest race tire I have been looking at seriously was 14″ with the street tires in the 12″ range. And I have plenty of raw stock for the floor, finally. So the floor will get a do-over. And that’s why those 9″ wide tires in the pictures looked so lost in there. Even the 10″ wide tires for the Mini Sprint-T would have been swallowed up.

While I am on the subject of the TGS2 I have been looking at a pull-rod spring instead of direct mounted springs for 2 reasons. One reason is I can change the spring rate just by changing 2 bolts, either a little or a lot, The second reason is the unsprung part of the pull-rod is much less than the direct mount spring because the entire spring and shock are moving with the car. Yes they move with the axle but they are entirely supported by the frame so they are sprung weight. The bellcrank and mount add a couple of pounds but it is all sprung weight. But the primary reason to go with the pull-rod springing is adjustability, I can change spring rate and ride height in just a few seconds and swapping a different length pull-rod is much cheaper than swapping different shocks and springs. Literally a dollars to donuts comparison, I can buy or make a custom pull-rod for about the price of a dozen donuts where a spring and shock absorber are $200-300 assembled. With my budget this is a cost-benefit ratio I can most definitely live with.

And I need to take a shower and hit the hay.

Still working on the spindles

I spent hours working on one bushing last night and it still won’t take the kingpin. It’s getting close but won’t let me slide the pin through the bushing, and I have 3 more bushings to go after I finish that one. Either the stones are worn out or these are very hard brass bushings. I think they are actually bronze rather than brass, but still, not supposed to be that hard. I was using cutting oil and everything so unless the stones are worn out already from the axle boss I’m at a loss.

Moving on to the scale mockup TGS2 I found some more card stock to use for the floor. There was an expired TGIFriday mailer under my computer that was printed on extra thick stock. I have revised the clearance cutout for the front tires, so now all I have to do is find time to cut it out. I think if I skip a day blogging I’ll have the time to do a couple of floors, maybe?

I’m going to have to switch to my backup scale bucket body because I have already modified my first one to build the Mini Sprint-T. That means I have to open the chopped T-Coupe rod model. I really haven’t decided what I want to build from that one. There are so many choices… And I have really no time to build models. Models from boxed kits that is, mockup models are required for, reasons.

And because I need to get to work on something I’m closing this one down now.

Mrs the Poet has only been gone one day and already my diet has gone to pot

Just got back from my first walk in over a week. Slight right glute pain because that’s my “long” leg and has to work more, and in my left foot which takes more of a pounding because it’s on the short leg. But otherwise I’m good after 2.6 miles there and back.

Tonight I had frozen Mexican Pizza for dinner. Yeah, I know, but I wasn’t in the mood for beans and rice. I took care of most of the leftovers last night, the little half-servings of stuff that was too little to make a meal out of but too much to throw away earlier in the week. And I think I might be dairy-intolerant in my old age. I have always had gas that varied from infrequent toot to crime against humanity in volume. Well just for grins and giggles I stayed away from cereal and milk, used non-dairy creamer in my coffee and skipped my nightly dab of yogurt and had a gas-free 24 hours. Next test is soy milk on my cereal, and maybe in my coffee, and no yogurt. The no yogurt thing is what is gonna kill me since I have some almost every night.

I have been thinking about how to show you guys what I have been thinking about, since my (free) CAD program doesn’t output files that can be read except by that CAD program and a few 3D printers and I don’t have a 3D printer (yet). What I do have is a bucket body in 1/25th scale, some tires in various widths and diameters, and some card stock, both the plastic and paper kind. So I’m thinking that I can dispatch two avians with a singular lithic projectile and get some actual building done while I make a visual aide for the blog. And actually see my thoughts in 3D outside of a computer screen or my head. Mostly my head, but I have managed to get it once or twice on the computer.

I’m listening to my YTM channel while I’m posting this, and it’s almost as ADHD as I am. The last 4 pieces were a Charleston demonstration, “Les Toreadors” from the Opera Carmen, “Immigrant Song” by Led Zeppelin, and Skynyrd’s “Simple Man”. There’s classic rock, classical, electro swing, ’60s surf rock, boogie woogie, psychedelic, ambient… and nearly every one was something I “liked” or similar to another I “liked”. I have probably caused the electronic equivalent of an aneurysm to the poor algorithm trying to decide what I like based on what I already liked and disliked. And now I really tossed a monkey wrench into the works by searching for the theme from the Alfred Hitchcock TV show under its real name “Funeral March of the Marionette”. And “liked” two of the pieces. My playlist “Opus’ fun junk” is almost as bad but I have at least listened to the whole thing end to end.

I have meandered on long enough, time to shut the brain down for bed.

I should do something with the mini Sprint-T

I have been neglecting the model version of the Sprint-T in favor of trying to fix the handling problems inherent in the design of the TGS2. I mean I know I should be doing something on it, but the inspiration has been lacking compared to the TGS2 and posting in the blog.

After it quit raining Sunday evening I went for my walk and picked up a bag of cereal. Yes I’m cheap and buy the bag cereal. It’s slightly cheaper per ounce than the box, we just don’t always have the $ to pay for a bag. I also get PopTarts in the big box except when the sales on the small box makes them cheaper per breakfast. Why cold cereal and PopTarts for a grown man’s breakfast? Simple, those are relatively non-lethal to prepare when I’m pre-caffeine. Cognitive functions generally don’t kick in until the second half of the cup, and it’s much safer to have things that don’t require the use of the stove or anything more complex than pushing the lifter down on the toaster. Even the measuring out of the various ingredients of my cup of coffee have become mostly autonomous. I can’t quite do them in my sleep yet, but I’m close. It’s when things change like switching from milk and sugar to pre-sweetened creamers that stuff gets messed up. More than once I took a swig of what was supposed to be coffee and got a slug of liquid candy instead. And for some reason that stuff just seemed to get sweeter and sweeter during the day. A few hours after pouring my coffee in I felt like pouring it out.

Speaking of my walk, it was so humid after all that rain I could have almost gone for a swim instead. It was 71°F with a 70° dew-point. UGH! sticky! At least it wasn’t hot to go with that sticky.

I would do more writing but my neck and shoulder are starting to bother me and make it hard to type.

Yay beer! And other things.

Just got back from the store with a new (to me) beer, Shiner Homespun Cream Ale. I have a new favorite beer. Seriously, this is the beer I have been looking for for years, slightly sweet and not over hopped with just the right balance of sweet and bitter. I must send a letter to Shiner and tell them this.

Work on the Mid-Bucket has slowed while waiting on the parts to arrive, some of which are still not made yet. I mostly have been analysing the frame for things to leave off and make it lighter. I have found 2 tubes that are redundant so far for a total weight savings of 5.5 pounds.

yay

On the Mini Sprint-T I’m almost done resizing the wheel halves for width after taking some time off for the Mid-Bucket. Filing the resin wheel halves is much quicker than the stainless steel steering arms on the Mid-Bucket, but because they have to be within a thousandth of an inch precision it’s only quicker in how long I spend actually filing them down compared to fitting the steering arms on the Mid-Bucket.

On the RPG front we are having some difficulty creating my character based on my life. Specifically my HP and natural armor or DR or in the terms of the game we are playing, Body and Hardness. Here’s the rub, the getting hit by cars doing from 25 to 30 MPH and walking away with minor abrasions is how Hard my body is in game terms. Getting hit by a truck at 60 MPH and barely dying is how much Body I have. Un-dying is a whole ‘nother kettle of fish that is covered by the rules but only for creatures in-game. And in-game I’m 129 years old, Mrs. the Poet has been dead at least 40 years, and I’m still living in the same house in Garland. I’m still mostly riding my bikes to get around except when I’m being a Runner when I have a couple of vans and cars. Also I’m an actual walking Urban Legend in-game having been a Runner since the events that created the game world. There are a number of people in law enforcement who don’t believe I actually exist, there are rumors I’m not actually human, that I’m some kind of avenging spirit, and even weirder stuff than that. This is going to be FUN!

On another front, my musical tastes are giving my YTM app apoplexy. So far on my saved music I have Jazz, Swing, Hip-hop, Classic Rock, Acid Rock, Electronica, Ambient, Trance… and whatever they classify Blue Man Group as. Seriously my tastes cut across so many genres My Channel is like listening to a radio that can’t stay on-station. If you can, do a search for Opus’ Fun Junk playlist. And prepare for your mind to get blown. 😀

And now I’m just doing the keyboard equivalent of babbling to hear my own voice, so I’m packing it in now. Happy Easter!

I have been busy even without Internet

Even without Internet access I have been busy on the Mid-Bucket and the Mini Sprint-T. For the Mini Sprint-T I have been modifying the resin castings into the right width wheels with the file and the digital calipers to keep track how wide the front and back halves of the wheel were. That takes a couple of hours for each wheel. For the Mid-Bucket I have been sketching to get the things I see in my mind on paper where you can see them, but not yet because they look like crap and are only partly done. I got the basic ideas down but as I was working I realized I had forgotten something very important, I neglected to include a mounting point for the front 4-bar on the frame. That’s kinda important as that’s what keeps the front axle in front, and not someplace in the middle of the car. And also controls axle wind-up under braking.

How I discovered that was I was thinking about what size links to put in my build list, and couldn’t remember how far the axle was from the 4 bar mounts. Then I tried to remember where the mounts were by remembering where the structure went when the penny dropped and I realized I had left some very important bits off the frame. And also left off the bits that triangulated the mounts for both the front and rear 4 bars. Not a great tragedy, but there would be some flex in the mounts without the bracing, enough maybe to feel under hard braking while racing. I did figure out where to mount the frame ends of the 4 bars, on the roll cage front and rear hoops. And I did figure out how to brace them so they won’t move around. It made the frame about 10 pounds heavier, but really there was nothing else I could have done except leave the mounts all floppy. Also the braces make getting in and out of the car much easier, like having a ladder permanently mounted on the side of the car.

The other thing that sketching out the frame did was confirm the engine mounts will in fact come naturally close to frame members, especially the front and rear mounts on the center rear frame member, but the left and right mounts are going to be right on and real close to the rear diagonal frame members, respectively. That means all the engine mounts are going to be on the bottom plane of the frame, but with the braces the rear of the frame is going to resemble a Birdcage Maserati.

All those tubes but no rollover protection...

Look at all those weld joints!

Now obviously I’m not going to go with such a complicated design, especially since it isn’t any lighter or stiffer than what I’m doing.

And since I need to get up early-ish tomorrow I’m putting this one to bed, and then me right after.

This is when I write about what I did

Earlier this week I was too busy doing things to write a blog post. Now I have a few minutes to write what happened. All I need to do is get the story straight in my head so I can put it on the screen. That is easier said than done.

Big news first, I lost my wallet again. Exact same way I lost it last time, from the same pair of shorts. I thought I was putting the wallet into the pocket, but it didn’t stay there. I probably lost it when I was sitting down after buying the day pass on the first bus of the day.

Second thing is I am no longer hairy. Well as hairy. I used a ½” guard on the top of my head and no guard at all on the beard. Then I charged up the electric razor and finished off the beard. Voila semi-fuzzy.

On the Mini Sprint-T, I think I have my tire mounting problems solved. I mentioned in an earlier post that I would be using a discarded insulin syringe to inflate the tire out to the edge of the wheel, well the other problem is the wheel making the tire grow larger in diameter by a substantial amount because it’s just too thick, for structural reasons. The resin used to cast the wheels is not as strong as the styrene plastic used in commercial model kits so it has to be thicker, basically all the way out to the flange diameter of the wheel. This in turn stretches the tire diameter by a similar amount, which drastically alters the scale relationship of the tire to the rest of the car. Well I’m going to try sanding out the inside of the tire bead so the oversize wheel so it doesn’t force the tire larger and see how that works. I have a spare set of wheels, and tires that I won’t be using on either model, to experiment with.

And I’m starting to get fuzzy around the edges of my mind, so I’m quitting while I can still hit the correct keys on the laptop.

A State of Detent Has Been Reached At Casa de El Poeta

Mrs. the Poet has been complaining about how I’m “not helping” her throw away my stuff when she does it during the part of the day when I’m still asleep. I don’t understand this. I don’t complain that she’s not helping me write when I start composing stuff at 0300 when the Internet is fastest locally and I can get to reference materials most quickly.

So we reached a compromise, in that Mrs. the Poet will not start throwing my stuff away until I get up, and because we both have things to do over the weekend I will start helping her on Monday afternoon after I have had coffee. There is something in the garage that she calls a “box full of rusty metal stuff” that I’m almost afraid to open. Then we don’t go into the garage again until after I get up Friday.

On other things I’m playing some more Shadowrun tomorrow, and there is a late race on Sunday, the Las Vegas race for the Monster Energy NASCAR Cup. And now that I have a new tube of GOOP™ I can continue to mock up the Mini Sprint-T street version. I haven’t found a model kit that has the Pentastar V6 as an option so kitbashing is right out. But I have that first wheel glued up and ready to test fit to the tire when the glue dries. I’ll probably do that Sunday while I’m watching the race during commercials.

I think too much

I was on a long walk to get some stuff at the hardware, and well, my mind also wandered. Specifically it wandered around the Sprint-T. What I was thinking about was what it could be like with the Pentastar 3.6l V6 DOHC aluminum block and heads engine that weighs a factory-claimed 326 pounds (as compared to the 545 claimed for the SBC and the 413 for the 3.8 pushrod engine out of the minivan) and delivers 305 HP in stock form. As a comparison the “performance” SBC in the first-gen Camaro was rated at 290 HP. In the Sprint T with the SBC and a TH 350 transmission I was looking at just over 1700 pounds empty, with the Pentastar V6 and the 42RE transmission coming in at 1450 pounds but that 42RE transmission would be dicey for racing use. The later models used 6 and 8 speed slush boxen that would survive racing but also weigh considerably more, the 8-speed being strong enough for the legendary Hemi. The transverse version of the 3.6 would bolt to the 41TE transaxle in the mid-Bucket and take 87 pounds off the weight and rear axle, while adding more than 200 HP over the engine as it sits in the minivan. Do I want one? Not if I had to buy it from the dealer with a car around it. Would I take a similar deal as I got on the 3.8l pushrod engine, remove a derelict vehicle to remove the stuff I needed to make a car for free? Hell I would even pay for a car that got wrecked in the back as long as it wasn’t more than $1K to get the 305 HP version of the engine and then swap the FEAD (Front End Accessory Drive) for the transverse installation. I mean 200 HP more and 87 pounds less would I take that? Hell Yes I Would Take That!

So the reason for the walk was to get the 7/32” drill bit and the small tube of GOOP for the bike and Mini Sprint-T respectively. I logged 3.93 miles and 25 checkins on Map My Walk and M Plus Places respectively and burned a lot of calories in the process. The weather was perfect, just warm enough and just breezy enough with a high overcast so that it was bright but not blinding.

And I have to get the rest of the stuff I do offline done so I can go to bed, so I’m putting this post to bed first, then me.

My toes are done and other things

OK I did my toes yesterday and picked up my meds. The toes were the same cost as usual, but my meds went up almost 500%, 471% to be precise. My usual pharmacy changed suppliers on this med and where the old supplier had a discount for monthly prescriptions the new one doesn’t. The new pill looks completely different in shape and color from the previous one. While I was going down the road I went ahead and got my bag limit for check-ins on my phone game, which is also working like it’s supposed to work. I just cashed in the gift card I earned last week and I’m close to getting another gift card on the side quest mission, just two more days to go on that one.

On the Mini Sprint-T I have been playing with the windshield frame from the donor kit to see if I can make it lay down like mine will with the posts I got from Speedway . Short answer: Yes indeedy. Unfortunately it takes both hands to hold the frame aligned with the body without using glue and since my mockup adhesive has gone walkabout I can’t put it together to take a picture. Since I have to visit the LRK early in the AM I’ll stop by the hardware and pick up another tube of Goop and some drill bits to install the tail light on the seat of the new bike. The mounting bolt measures 3/16” so that’s the drill I’ll be looking for or maybe a thirty-second larger.

Well, I have to get up at Oh-Gawd-Thirty in the Aye-Emm so I’m going to let it rest now.
