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.
I really need to replace my futon, because I lack padding on my right hip and when I sleep on my right side I get a painful not-quite-a-bruise on my hip. I never in my life though I would ever say I wasn’t fat enough, but … I really need a new bed.
I’m doing the channel bounce as there is a F1 race and a Monster Energy Cup race on at the same time, and the NHRA race just started broadcasting. I’m mainly sticking with the F1 race as Hamilton had a flat tire on the first lap and there is a ton of drama because he went all the way to the back of the field and he could clinch the championship this race depending on where Sebastian Vettel finishes, unless Hamilton finishes 5th or higher. As I type this Hamilton is leading the points by running in 9th with Vettel in 3rd at the finish to clinch the driver championship two races before the end of the season.
Watching the Monster Energy Cup race now from Martinsville.
Just got a text that the Shadowrun game we had going tonight was dropped because the GM has another class to attend, and one of the players for our group is having some kind of health issue. This makes me slightly upset, but not totally broken. As the saying goes, shit happens. I’m just getting tired of shit happening to me.
Speaking of that, I didn’t win the lottery again last night. So I’m still p’, too impoverished to buy a vowel.
This Sunday I took a fall when I pushed up from my chair and before I could get my feet under me the chair went rolling backwards, dropping me on my tailbone. Then yesterday I did 3 miles even to max out my check-ins in as little time possible, only it took longer because of poor route planning. My butt didn’t hurt while walking, but it made up for it when I had to wait for the check-ins to become active again. I will know better for tonight.
I did a bit more Googling and I now know how much that engine and transmission weigh as a group. The Pentastar V6 engine weighs 326, the 62te transmission 220, right on my previous estimate based on the 41te the 6 speed is derived from, so the total is 546, one pound heavier than the SBC 350 without a transmission. Or rear axle, driveshaft or a whole raft of other things that are part and parcel of the 62te in the picture, but not the halfshafts or suspension that are also in that picture. The traditional 350/350 engine/trans combination for a bucket comes in at a combined 670 pounds, throw in the cast iron 9″ Ford center section and differential and you have about 740 for the (almost) equivalent of the picture. Thing is that picture is of the drivetrain of a full sized commercial van with a GVW of 8550 pounds, not some wimpy minivan. The drivetrain in that picture would have no problem with a 1500 pound Mid-Bucket. It is a pity then that I’ll never get to install it in one. The Mid-Bucket weighs about half the cargo rating of the van the powertrain in the picture comes from! I could literally drive the Mid-Bucket inside the box and drive the van away without overloading it. I mean how cool is that? And using that transmission on a vehicle with a GVW of 8550 pounds means they finally fixed the reliability problems of the 41te.
Enough car talk, I need to get ready for my walk.
