How Much Better Is the Updated Quick-Lok Power Head?

I want to get the brush cutter quick-lok attachment. I have the older 2825-20 power head, string trimmer, and hedge trimmer attachments already.

At the HD I can get just the brush cutter for $169. Or there's a deal for the brush cutter as well as the new 3016-20 power head, another string trimmer attachment, and a forge 8.0 for $349. So an extra $180, for the head, battery, and spare trimmer.

Another on here said the new power head is much better. And I do overheat/load mine on occasion where it stops working for a bit. Another battery would be handy, I do have a lot of Milwaukee now and can always use another good bat. And I guess a spare trimmer head couldn't hurt.

Maybe I could sell or make a gift of my old power head and older trimmer head.

Kind of sounds like a deal worth doing, but I'm open to opinions. A lot depends on how much better the updated power head is. Thoughts?

Counter Intuitive Traction Observation

I've observed that when my AWD car is understeering badly if I apply throttle it'll rotate more. This makes sense on a loose surface like gravel or snow, but I've observed this on tarmac as well.

This goes counter to everything I've seen or read about traction. Everything I've seen or read says that applying throttle during understeer is exactly the wrong thing to do. It transfers weight off the front and puts the front tires even further outside their traction zones. Yet I keep observing this.

I can't be 100% sure at this point that the car's ESC system isn't doing something to cause this. It doesn't have any of the fancy torque vectoring differentials and I'm not noticing it doing anything, but it might be applying inside brake that I'm not noticing. Though still this seems unlikely as if it was it'd likely do it off throttle as well and it feels like the outside front is pulling not the inside dragging.

Maybe the way my AWD system works it's actually slowing the front tires relative to the rear. It's a RWD based clutch system, so applying power causes the clutch to grab. Because there's no center diff and the front tires turn a larger circle, it may actually be slowing the front and spinning the rear more. But again as I said before it feels like the outside front is pulling the nose of the car around.

Has anyone here noticed such a thing, there's quite a few here who track FWD cars. I figured maybe some FWD drivers might observe something similar.

Talk To Me About The Lawn Mower

So I got the string trimmer when I was tired of dealing with a gas one. Then got the chainsaw when I was tired of dealing with my gas one. And now I'm tired of dealing with my gas lawn mower. And could use a couple of Forge 12.0 batteries for my trimmer, saw, and vacuum.

So is the lawn mower worth it? Does it rock? My yard is 1/4 acre and flat but I'm constantly being invaded by blackberries, these cat tail things, all kinds of other crap, so sometimes I'm really working my lawnmower. Would the Milwaukee stand up to it?

Admittedly the string trimmer struggles at times, I overheat/overload it and it quits on me me sometimes until I give it a few min and a fresh battery. And I also often stall my gas mower cutting my thick grass and weed mix.

The homeless despot has the mower and 2 Forge 12 bats for a $1000, is that the going rate?

Edit: I bought it.

M18 HD12.0 Battery Crapping Out, Options?

Got a couple of these suckers and one just isn't performing. When supposedly charged the indicator never shows more than 3 lights, and in use on my string trimmer it gives up quickly.

It's 2-3 years old but started doing this last year I've just been dealing with it. Now it's getting worse and a problem trying to get yard work done this summer.

Edit, it's out of the 3 year warranty.

Do I have any options besides just buying another new battery? Warranty, repair? I'm kind of handy, can I figure it out and fix it?

Tire geometry, using tread width, wheel width, and section height to determine sidewall angle.

I'd think we can all agree that having a wheel width wider than the tire or at least tread width is preferred. That it provides for a much more responsive sharper handling tire. But how much wider and which numbers do you use.

This effect of using a wider wheel at least in part presumably is an effect of the triangulation of the tire. That when on a wider wheel the tire is a trapezoid instead of a rectangle. If so then the profile/section height matters as well. A higher profile means it'd take a wider wheel to achieve the same triangulation.

So then would be be possible to use some observations and basic geometry to determine an ideal sidewall angle? And then use that when deciding our tire/wheel widths?

-

I'll use the data in this Tire Rack YouTube video as an example. They tested two tires on two wheels. Both tires are RE-71RS in 225/45R17 and 245/40R17 on an 8" wheel and a 9" wheel. The basic conclusion of the testing was that the 8" was bad all around, slower and felt sloppy. The interesting part was with the 9" wheel the 225 was just a hair off the pace from the 245 but the 225 felt more responsive. Clearly of the 4 combos the 9" wheel was right for the 225 tire. It's interesting to note that the suggested wheel widths for the 225 is 7-8.5". I also suspect had they had a 10" wheel the 245 would have been better.

So the 225/45R17 RE-71RS has a tread width of 7.9" and a sidewall height of 4", on a 9" wheel. Put that into an online calculator and we get a sidewall angle of 82.1deg.

Do the same for the:

  • 225/45R17 on the 8" and it's 89deg
  • 245/40R17 with a tread width of 8.4 on the 9" and it's 85.7deg

This small data set suggests the ideal angle is between 85.7deg and 82.1 degree. So could it be possible to gather enough data on which combos work best to better narrow down that ideal angle? If so how useful do you think it'd be? Or am I just off on another one of my weird tangents.

SpaceX Sun Synchronous Orbital Ring

I don't think Elon has said anything about an orbital ring. But I got to thinking and doing some rough math and at the scale he's talking about in the recent video about space data satellites. That appears to be where this is heading.

The only logical orbital inclination for the data satellites is a sun synchronous orbit. So while the satellites can vary in orbital height, the inclination will be constant.

The circumference at the orbital heights he's talking about is roughly 43,000km. The proposed AI1 satellite they showed has a wingspan of 70m. With those numbers to put enough satellites up that they'd touch at the wingtips is 614,285 satellites. A staggering number, considering there's currently about 10,000 Starlink satellites.

One might then think that's it, such hypotheticals are ridiculous. Then he goes on to talk about 100GW and even TW power levels. The proposed AI1 satellite is 120kW, 100GW worth of those satellites would be 833,333 satellites.

Even if we ignore the satellite specifications, the governing factor here is solar panel area. If we figure it at 250w per square meter, 100GW is 400 million square meters of solar panel. If that was one circular panel orbiting the earth it'd be a panel roughly 9m wide, at a TW of course that becomes 90m

Now of course in reality if SpaceX ever does put up that many compute satellites they'll put them at different orbital heights so they don't impact each other. But at a point it'd start making since to link them together physically. And at that point they're building an orbital ring.

Custom Uppers?

On the website in "design your own boots" > "lace up - build your own" at the bottom of the options list is "custom uppers".

Does that $100 charge get me pretty much anything I think of as far as uppers go?

Furthermore there's a $200 charge for 16" height, and all tall boots are custom uppers. How would these two options overlap? Could I select both, pay $300 and get anything i want at a 16" or more height?

Ohhh and I don't see the double mid sole option anymore, is that no longer available?

Best car to fit my desires?

I'm in the US and pondering options vs my current ride. Maybe you all can point me in the right direction. So I'll throw down a list of what's important to me, what car does this list best?

  1. Big luxurious sedan, I like my elbow room, comforts, and trunk space.
  2. Power and performance, I'm an um assertive driver and would like to take it to a track.
  3. AWD, RWD based and able to shut off the front as well as traction control.
  4. Towing and hitch. I find it really handy to use a 2" hitch for racks, towing, etc.
  5. Range, I want to stop for fuel when I choose, not when the car does.
  6. Self maintain, repair, and mod. I currently do it all myself and want that to continue.
  7. Bang for the buck, how much I get for my dollar matters much more than the total. I've never bought a new car and it'd have to be a really compelling car/deal for that to change.

The effects of different steering rack ratios?

I don't have much experience driving with different steering rack ratios in otherwise similar cars and conditions. I thought maybe users here might and could offer some thoughts.

I've been thinking a quicker ratio would be good. My car was produced with three different rack ratios. Either my current 16.5, 15.5, or 14.4, so I have those options easily open to me. It's a rather simple hydraulic rack, no EPAS, no variable ratios, and it's a 120" wheelbase. This car is a daily that I sometimes track for fun, not a track car that I can drive on the street.

The question is really two fold. What are the things to consider? And do I swap in the 15.5, or jump all the way to the 14.4?

Camber's affect on scrub radius?

When scrub radius is explained it's often explained as where the centerline of the steering axis contacts the ground in relation to where the centerline of the tire contacts the ground. However I think it'd be more accurate to say it's the center of the pressure where the tire contacts the ground. This would mean it's affected by camber. But I've never seen anyone talk about scrub radius and include how camber affects tire loading and in turn it's affects on how scrub radius affects handling.

In the image above the left side is the common representation of zero scrub radius, shown with zero camber. To the right I've added some negative camber and the purple line for vertical, presumably the center of pressure while going straight. In the right image is scrub radius effectively negative?
