The fur kids are starting to miss Mrs. the Poet, Happy 4th of July

Clint and Clyde have noticed that Mrs. The Poet isn’t here to sit on, on the couch. Actually I think they noticed she isn’t here to wait on them hand and foot.

I’m running out of paper cardstock for the scale mockup because we have recycled so much of our junk mail there was only one small sheet left, so when I screwed up the front wheel cutouts for the floor there wasn’t enough left to do another one. And now I won’t get any of that kind of junk mail again for a long time, because I actually want some.

I could make mockup tires from 1″ dowels sliced and painted black. The IRL tires I’m looking at are all 25 to 26″ tall which is 1″ to 1.04″ in scale, and 7″ to 12″ wide which is 0.28″ to 0.48″ in scale. Doweling is cheap and easy to work with, so that might be the tire solution, cut them slightly wide and then sand them to the correct width.

I need to get my act together this morning and get to Harbor Freight for their 4th sale. Mrs. the Poet wants me to get a screwdriver set because I left mine where I was working out in the garage and people have been moving things around and just putting my stuff anywhere in spite of repeated admonitions to not move anything so I could find it again. But nobody pays me any attention when I ask to leave my stuff alone.

Anyway I need to do a lot of travelling locally today so I had better get a quick nap in before I have to go.

I didn’t want to do it this way, but I have a working tire pump now.

Well I had two pumps, one that failed somewhere in the piston and the other one that had a rotting hose from the pump to the chuck. I only have to send one back, so I put all the bad parts in the return box and assembled all the good parts into a working pump. I then used that pump to get my tires back up to the minimum 70 pounds per square inch to prevent pinch flats on potholes.

And after I did that I felt like Superman™ so I tried to mount the tires to the wheels I had just mocked up that afternoon. It was a struggle, but as you can see:
Wheel reduced from a scale 10 inches to a scale 8

I got the front edge even with the bead on the tire, but I need to pump the tire so the back side matches the front.
Back side sticks out a little bit, don't it.

It’s hard to see from that angle, so this is easier.
See all that white? Not supposed to be visible.

So what I do now is talk to my diabetic friends about getting some used needles and syringes to pump up the tires to meet the beads of the rim.

And there’s something good coming on Science Channel, so I have created enough with the words and pictures, Opus the Unkillable

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.

Just chillin’

I need to go to the hardware and get a file or 3 to fix the steering arms so they fit the spindles, but right now my foot still hurts, so I’m sitting tight and just chilling and reading Twitter and web comics on separate devices. I prefer to use my phone for Twitter, and my laptop for webcomics, so until just now I was bouncing back and forth between the two like some kind of screen addict. Now I just have the laptop active while I do the blog post. The weather forecast is that tomorrow and Wednesday will be much warmer so I’ll do my walk then and get the files. Actually I’ll probably go to Harbor Freight on the bus and get a whole set of files. And I can also use these to make the Mini Sprint-T, files are useful tools.

So I just finished my walk to get the $$ for tomorrow’s shopping trip and it was about the same temp outside as it was in my office when I left, but now my foot hurts again. Tomorrow should be better.

I spent most of yesterday unconscious, also a large chunk of today

There is something out there that is trying to kill me, and not even aware of what it’s doing. Some tree, weed or grass is attempting to reproduce and in the process is making me miserable. I have burning eyes, a nasty post-nasal drip, and a hacking cough from the post-nasal drip. I have a treatment for it, but that treatment is also the same thing I use to go to sleep at night, and the known dose for treating allergies is twice what I use as a sleep aid at night. So I have a choice between awake and miserable, or asleep and not feeling like I’m stuck underneath a stampede of small cattle. That caught under the stampede feeling is because the intercostals in my chest are exhausted by all the coughing caused by the runny nose/post-nasal drip.

On the Mini Sprint-T front I have almost determined the length I need to cut the rear axle tube so that the rear tires track is the same as the front. The stock for the rear axle tube protrudes exactly 0.125″ inside the hub, and the brake disk has to be 0.1428″ from the front of the wheel mounting surface for a scale caliper to fit between the hub and the disk. Subtract the .0675″ thickness from the front of the mounting surface to the back of the hub as received and the back of the hub needs to have .0753″ of added material for the mount for the brake disk. That means the front axle will have (2 * .1428) + 1.92 inches or 2.2056″ between the mounting flanges, and the rear axle tube would be 2.056 – (2 * .0675) + .250 or 2.3206″ long, leaving .68″ for making the standoffs for the front hubs which would be the same 0.200″ as the rear hubs. Yay! for having more than enough raw stock on hand. I’m still pondering the choice of material for sculpturing the back side of the hub for mounting the disk.

Off on another tangent, I madecollected $6 this weekend from that game app on my phone that pays me to play it. So Yay! money from playing on my phone like it was a job. This is the same source of funds that I used to buy the rice cooker/vegetable steamer back in July, so perseverance and patience will get me good stuff. I have also used these funds to purchase most of the things I am using to make the Mini Sprint-T. The kits I bought for inspiration and as a source for making the body, the engine for the SBC version, the tires for the street version, and all the raw stock for making the frames, were all sourced through Amazon. The water pump and front engine mount, the LS7 engine and the 700r4 transmission for the SBC engine were sourced through VCG Resins, while the wheels, hubs, rotors, and rear axles were sourced through Ron Coon Resins . Those items were bought with money from other side gigs.

And that’s pretty much all I had to say today.

I live, I die, I LIVE AGAIN!

OK if that sounds familiar it’s a quote from Mad Max Fury Road. And it’s perfect for the day I started composing this post, because 15 years ago I died. Not that I try to keep that a secret. But yeah, one more year and I can drive again.

Now, I promised that my next post would have pictures of the new wheels and rear axle for the Mini Sprint-T.

First up, what fell out of the bag after I broke the seal.

Wheels and hubs and the brake rotors in a small plastic bag.


The rear axles, center sections and axle tubes. The 1/1 scale center sections are stout but light.

The brake rotor on the hubs as delivered does not leave room for a caliper.
If you look carefully you can see the hub resting against the rotor. Not good.

Wheel outer half, hub, and rotor sitting separately.

The hub in the wheel.

The axle tube will become the standoff for the rotor so there is room for a brake caliper between the hub and the rotor.

The hub on the tube with the rotor.

Now you can see how the standoff is supposed to work.

And you can see the problem with the wheels and tires as a team.

You can see how far the whole wheel sticks out past the tire.

As you can see I have a bit of work to do to make these fit the models, all the hubs need to be fitted with the standoffs and the axle tubes trimmed to the right width for the car, the standoffs need to be slightly sculpted to match the 1/1 hubs so I will be buying some Sculpy to bridge the gap between the hub and rotor. But this car build is moving along.

The next issue to take care of is the differences between Henry’s Tin and Speedway’s Fiberglass. As I was laying out the frame I noticed the body wasn’t lining up properly, so I did a bit of measuring on the model body and the Speedway body and a bit of research on the Internet I found out that the kit body was pretty close to the 1925 car it was modeled on, and the Speedway body had been “stretched” a bit to fit “late model” humans in width. With the cowl problems I already noticed that means I need to do a lot to make the kit body fit my frame. So what I decided to do is a 3 step process to go from the AMT kit body to the Mini Sprint-T body.

Step one is filling all the holes in the AMT body with plastic Goop-ed in place and pulling a mold off that. Then I can remove the fill pieces and use the kit body as intended for the kit. Using this mold I cast a hard resin plug to use for stage one of the body mods, work the plug over to correct the contours of the cowl and back but don’t widen it yet.

Step two is taking the cleaned up plug and pulling another mold from it, then pulling a vacuformed body from that mold. The vacuformed body is then corrected for the width issue, filled with resin and cleaned up to make another plug for another mold that I can use to vacuform the final body. If I like the way the final body turns out I might do a run of bodies until that final mold wears out. If there is enough interest I can then use the final plug to make another mold and the process continues until I get tired of it or people get tired of buying the body. Step 3: Profit! 😀

And a little late posting, but here we are.

The parts came in today!

The hubs, wheels, brake rotors, and rear axles for the Mini Sprint-T came in the mail today! Yay!

Everything is going to require some kind of modification from the delivered state except the brake rotors for the front wheels, they are within a couple thousandths of an inch of being the right size and only the rears will require any change in diameter since they are about a half-inch smaller in 1/1 scale and that would be noticeable in 1/25 scale.

The wheels measured out as 10″ wide bead-to-bead in scale, with the street tire wheel needing to be 8″ and the race tire wheel needing to be 14″, some work needs to be done on all of them. The back half of the wheel measures out about 2″ too wide for the street version, so narrowing that to the right width will get most of the adjustment for the street tire. The back half measured too narrow for the race wheel by a couple hundredths of an inch and the front half was over 0.1″ too narrow for the race tires. Both of those will require some finicky work to get the right width.

One thing that will require work is getting the rotors the right distance away from the back side of the hubs. As delivered the rotors mount to the rear face of the hub with no clearance, but 1/1 the rotors are spaced away from the hubs in different widths depending on the brake calipers being used. The solution for that is very easy. The rear axle tube is just the right size material for this and the tube will have to be trimmed a large amount to get the width right in the back. So the hubs and rotors will be glued to the rear axle after trimming for the right width and brake rotor offset, then the leftover bits of the rear axle tube will be used to build the front spindles to the right size and brake rotor offset. The tires won’t roll, but that is a small price to pay to get the offset right. That does leave me with two metal axles that run inside the rear axle for the tires to roll that are redundant. The front wheels won’t turn left and right either as my tools won’t let me work that small.

Naturally all of these modifications will work much easier with a lathe for making square cuts in round parts. Hint, hint.

I’ll have pictures ready for tomorrow’s post, I promise.

More on not being depressed, this might get a little repetitive

So far this week I have gone to the Lab Rat Keeper, and bought a stamp and mailed a letter at the post office in one day, taken a 2 mile walk to buy cat food, fixed dinner (beans, rice, and vegetables) and had a conversation with Mrs. the Poet on another day, took another two mile walk and had another long conversation with the Mrs. on another day, had a shorter conversation with Mrs. the Poet, went grocery shopping, had another two mile walk and stopped to correct a $0.40 mistake on the grocery bill yesterday, and so far today I had a conversation with Mrs. the Poet plus all the regular maintaining life functions stuff and the day’s barely half over. The conversations are what has Mrs. the Poet excited the most. Seriously this is like meeting an all new person for her as I was already depressed (but didn’t know it) when we first met.

The letter was an order to Ron Coon Resins in NE for 8 Wide 5 hubs, 8 disk brake rotors, 8 wheels, and 2 quick change rear ends. I’m at the point I can’t do the front axles without the actual hubs I’m going to use, so this will let me move on with the build(s). Yes that was a plural on the build, I’m making the “ultimate” build with the LS7 engine at the same time as the “most probable” build with the Small Block Chevy, so I have a 3D blueprint for making either one of them. I’m still trying to find brake calipers for the rear brakes, I found some good ones for the fronts but GM Metric calipers are very hard to find in 1/25 scale. In contrast 1/25 or 1/24 scale 4 piston calipers are common. Most are not cheap (except the Model Car Garage die-casts at $5 a set of 4) but they are available.

On another note I have been thinking of how I could get some pedal time in while I’m on the computer, but I’m at a technical impasse. Anyone know how to make a Chromebook shut down gracefully when the voltage is taken away from the charge port? I think this would be a software thing. I’m trying to get my computer to run on a pedal-powered battery charger and use the battery to keep everything going in sleep mode when I quit turning the pedals. I’m thinking connecting the pedals to a car alternator to make dirty 12VDC then filtering that to the clean 9VDC the computer needs with lots of caps and “stuff” to make an LC filter and a linear regulator for the final output with another filter cap across that output to make it absolutely ripple-free, and then plug that into my computer.

One week until my Death Day celebration

That’s right, next week will be 15 years since I died. I’m trying to decide how to celebrate it, I’m thinking another zombie theme party complete with Jello “brains”. But I am open to suggestions. This is a celebration that while I died, I didn’t “stay dead”. I think the same thing that enabled me to fight through 40 years of depression without giving up completely also wouldn’t let me stay dead in the street after I got hit.

This year I would like gift cards to Starbucks or Amazon, or a small lathe if anyone has one they want to get rid of. I could do so much with something that would let me turn stuff up to 2″ diameter and down under 1/16“. I could make my own tires as a fer’instance. I could make my own rims from aluminum barstock, or widen and narrow kit wheels to fit other tires. There would be a lot that I could do with a small lathe, things that I could monetize. Building a model race car and need some oddball size race slicks? Easy peasy. Making road tires would require turning the tire to size and somehow carving the correct tread pattern into the blank, I’m not sure I could do that as I’m not a sculptor. Thinking about it I can follow a pattern that I could print off and transfer to the blank, by making the pattern from a picture of the tire in question. That would be time-consuming but doable. And then cast a rubber tire from a mold made from the blank. Thinking about it some more I could also make tires that don’t exist but could, like a 26X16.50R-15 Hoosier Pro Street. Currently the shortest 14″ wide tread Pro Street is 29” tall, that nobody makes a scale replica of anyway.

But enough of lathes and what I could do with one. What kind of party do you suggest?

Sorry I haven’t written…

OK catching back up, I’m on antidepressants long enough to have them adjusted twice now, and I’m “officially” not depressed, and the side effects are easing off. This particular med has some side effects that are distinctly unpleasant if you have had a UTI and that’s all I’m going to say about it.

I took several days off right when Mrs. the Poet got back from NY to go to my 40th HS reunion. I found out my face hasn’t changed much since I graduated based on the number of people who recognized me at the pub during the pre-reunion meet and greet. I also found that there were a number of girls wanting to go out with me if I had just asked, but since I didn’t…

I’m finally getting enough parts to start building the Mini Sprint-T. The order for the wheels, hubs, brakes and rear axles goes out tomorrow. I’m building two versions, so I’m getting the running gear for both in the same order. The main difference is one car I will have to narrow the wheels for, the other I will have to widen them. One will have 10″ street tires on 8″ rims, the other will have 14″ race slicks on 14″ rims. One car will have the LS7 and the other will have the SBC backed by a 700r4 automatic transmission. Both will have EFI, it’s just that the one on the SBC looks like a 4bbl carburetor with an extra fuel line and electrical cables.

I have found the steering box I’m going to use Classic Performance Products VEGA-PSB Power Steering Box. This box has almost the same ratio as the $600 Sweet 800 box for a lot less money and is a lot easier to integrate into the front end. The Vega box is much smaller than the 800 box and fits the same mount as the Vega manual box. I went to the manufacturer’s web site and downloaded the dimensions so I will be able to accurately model it.

And that’s pretty much everything I didn’t mention last time I posted. Opus
