Planning a trip

I’m going to make a trip to Harbor Freight tomorrow to pick up some things. I need a new 12v power supply (battery charger) for electrical testing, and they have a sale on kitchen shears ($0.39). Also I need to get a cordless version of their take on a Sawzall . This will be necessary to cut the headlight buckets out of a car or truck in the junkyard so I’ll have a way to mount my headlights in the front fenders.

Along the way I’ll also pick up lottery tickets and some candy for Mrs. the Poet because she’s getting a little stir-crazy from not being able to leave the house. She’s been stuck here since she was released from the hospital back on 3/8. I need to get some stuff before I can do anything more on the Mini Sprint-T.

Speaking of which, I have maybe solved a problem with the Sprint-T. One of the things I want to do is use a Tri-Y exhaust manifold, which is expensive as Hell for LS architecture engines. The reason I want to use this is the Tri-Y configuration improves low and mid-range torque without restricting flow at higher RPM for peak power. Well what I want to do is use a dual inlet, single outlet muffler on both sides to act as a large-volume collector and massively boost low and high RPM power because that’s what theory says it will do. Another thing this will do is quiet down the engine a bunch without restricting it any. For the model there are muffler bodies without inlets or outlets available that can be customized exactly for this application. Unfortunately I can’t link to these because the web site they’re sold from doesn’t let me link to individual parts and when I try the links just go back to the products page. parts See?

So, after lunch I get to catch a bus, wait a while to catch another bus, ride for a while, shop, and wait again for the bus home, unless I time my shopping trip right, then wait some more to catch the bus home. [Yay!/s]

Robert Burns was an optimist.

In case that went over your head he was the one who wrote the comment about making plans whether you were a mouse or human. Depending on which transcription you have the last phrase reads either “gang aft agley” or “oft gang agley”. Well today’s plans went very “agley” because after being awake for nearly 20 hours and spending several hours on various “devices” my neck decided that I wasn’t going to be taking any walks. And paying taxes required a long walk of about a mile, more or less. So connecting the dots, working the Venn diagram, whatever you want to call it, I was not able to pay taxes. And I didn’t get to bed until about 1400, which was shortly before I got up yesterday. Now tomorrow will be fun as I spend another 20 or so hours awake to reset my sleep cycle to something resembling diurnal. After I get back from grocery shopping.

Speaking of shopping one thing I still need to get is butane for the plastic bending torch. That original sentence was “rod bending” but then I remembered some of my raw stock was only available as tubing in the size I needed, so “plastic bending” now. And I’m finding out stuff about what I need to use for the bending form. The SFI rule for certifying roll cage/bar bends is they need to have a minimum centerline radius of 3*D where D is the outside diameter of the tube used in the structure. That means I need to make my bending form 2((3*0.060)-0.030) in diameter for scale SFI-certifiable bends, or 0.3″ diameter which is almost exactly the OD of a 5/16″ fine-thread bolt over the threads. So my bender would have a 5/16″ bolt with washers permanently fixed just over 0.060″ apart held in some kind of fixture and the OD of the washers turned down to 0.420″ to allow for the bender follower to force the stock against the OD of the bending form. And I know that’s a lot of technical babble for a paragraph, much less for a single sentence, Gomen nasai and I really hope I spelled that right, it has been more than 20 years since I was in a Japanese class. In case I didn’t spell that right that is the Formal Apology (I don’t remember the informal form), because when you inflict your mistakes on strangers like I just did you must use the Formal form to apologize.

Moving on… the weather has done a Texas Weather thing, we are going from nearly 70°F this afternoon to just above freezing with rain and gale-force winds in the morning. 😡 and 🤒 At least both cats were smart enough to come in from the rain this time. 😼 The forecast for grocery shopping is less rainy, warmer, and less windy.
