Good for mythbusters, I've seen plenty of burnouts leave flaming piles of rubber in their wake.
Actual fire coming out of the rubber or smoke?

I'd tend to agree with this, mainly because they have to restrict what they show from a legal standpoint. If they say "yeah if you drop your clutch at 5000 RPMs you'll set your tires on fire" guess who is going to get sued when some dumbass goes out and does what he just saw on TV and ends up setting his car on fire.
Have you seen the poo poo they do on Mythbusters? Getting sued because of what a viewer might do doesn't seem to be a big concern. Dropping the clutch @ 6000RPM (with the tires submerged in gasoline) would be amongst the boring poo poo they've done.

Potentially stupid question, but why don't engines have some sort of thermal protection that shuts them down before they get hot enough to catch on fire or sustain damage? I mean clearly there's a temp sensor since an overheat light comes on, why doesn't it just shut off?

My guess is it wasn't the engine itself that overheated, it was something close to the engine that overheated due to lack of airflow and revving the piss out of it for an hour.

Before buying a car people should have to study kinetic and static friction. When there is no relative motion between two objects there is static friction. Static friction rises to meet force until it hits its max value (weight*grav*μs) then it drops incredibly fast and flat-lines at its kinetic friction (weight*grav*μk).

Rubber on concrete has roughly a 1.0μs and a 0.8μk whereas rubber on ice is closer to 0.15μk (can't find decent rubber-ice μs values.) The drop off for a slipping tire on ice is massive compared to concrete.


Years and years ago, I worked part time at a auto parts store. I had a guy come in and he wanted an emergency tow strap for his little poo poo box. Honda or something. Note he wanted it to do an illegal tow (IE: Just moving it) from his buddies place to his or something.. not to actually recover the car stuck in a snow drift or anything.

Anyhow, the thing was rated for 4000lbs breaking strength or something like

:2bong: MAN! It'll break for sure! This is a piece of poo poo! You shouldn't tow a motorcycle with it!

:) Well, I'm not going to say it isn't a piece of poo poo (I like rope/chain combo personally) but I'm sure it'll work for you. What are you moving with it?

:2bong: My Accord (or whatever)

:) Is it stuck?

:2bong: No! But this isn't enough safety factor

:) Um, you do realize you're not lifting the car. You're just pulling it

:2bong: :confused:

:) I mean, you understand you don't need 3000lbs of force to move your car. You can push it yourself right?

:2bong: Yeah

:) There you go.

:2bong: :confused:

I was told by an instructor in the automotive program at a tech college (who'd been instructing for 15 years, mind) that you should never ever touch the brake pads with your bare fingers because the oils will cause the pad material to blister and expand outwards under heat. Sort of like why you don't want to touch headlamp/high-wattage lightbulbs.

I'm pretty skeptical of that and I don't think that's a fair analogy. Any miniscule human oils on the surface pad would be worn off the first time you touch the brakes. With a headlight bulb that remains on the glass.

Practically, most of us that have installed pads have not done so in a super clean environment using gloves at all times handling them. I personally haven't had any funny wear/early failures that I could even remotely equate to touching them.

Got a call from a good client of mine the other day.

:phone: Hey Slidebite! Mind dropping by the plant? We've got a parallel shaft reducer that's getting a little noisy, I'd like you to take a look at it.
:) No problem. Be there in a few hours

(2 hours later,)

:phone: Yeah, uh, we'll just send it to you. It started sounding pretty bad so we're putting the spare in. See what you can do to replace it or rebuild it for me, K? Thanks. :love:
:) Love to, fire it over.

Next day, a pallet arrives in my warehouse.


Oh, yeah, there's your problem.

Ooooooooh


For reference, at one time this was a spherical roller bearing and looked like this


This is around a circa 1970 gearbox and while I can indeed get a new one, it's about a $60K touch for this exact unit which is stupid. I can put in something a little more modern including an integral motor for about half that which would also get rid of the V-belt input.

At this point, I'm hoping for the clients sake the first stage of reduction is salvageable and we can get away with just the secondary gears and hopefully reman it for <$10K but I am really not optimistic they're relatively unscathed. The amount of material in the sump was something to see, even though it was already drained.

Went out for dinner with the folks last night and drove their 1998 Accord. I swore to god that thing had no headlights at all and told dad to come by our place today to check the car out. He didn't think there was a problem because "whenever they change the oil they check the lights" :v:

Pics to follow (they are actually in my garage trash but I should pull them) but the 9005 and 9006 bulbs were original from 1998 when they moved to Belize and drove the Accord there and back, several times since. They still worked (sorta) but had a definite black tinge to them and a couple had a couple of melted glass bulges.

I can picture the Honda oil guy saying "OK, turn on your lights" and seeing something resembling "light" so A-OK. Check. I was kind of surprised they weren't blown.

It's got some fresh Walmart Sylvania Specials in them right now so while not exactly high-end, they'll look like awesome HIDZ to the folks I'm sure.

When I was in Hawaii last month my rental in Kona was a 200 and it was absolutely abysmal in so many ways. Quality, performance, ergonomics, pretty much everything except fuel economy which I will say was reasonable. The Malibu I had on Maui immediately after was literally 3x the car. I can't imagine how someone could buy a 200 if they just test drove basically anything else in the same class.

Alberta used to have milk in bags but then something happened. We also had home milk delivery and fake bricks on the outside of our homes in which to place money for the milk deliveryman and in which he would place the milk to insulate it against the cold.

:bahgawd:

That's old even for me. I remember grandpa and grandma having milk delivery and how they left tokens for the delivery man. He had a full dairy price list in tokens, like 1l of milk 2 tokens, cottage cheese 3, chocolate milk 2, etc. I thought that would be the coolest job ever when I was 5 years old.

I am thinking that disappeared in the early 80s?

I can't remember the last time I saw milk bags. I will keep an eye out next time I go shopping to see if they are even available here.

When I was a teenager I worked at a tire shop and that was an almost everyday occurrence.

Salon lady said sure and motioned to the door in the back of the salon. 10-15 minutes later, lady comes out just saying "I'm sorry, I'm so very sorry" and leaves $20 on the counter and books it out the door. Salon lady goes WTF and heads into the crapper.

Even if it doesn't weld the elements (spherical bearing in the pillow block) it's an express way to fluting the bearing which will lead to premature failure.

Is that grease? It sort of looks like it but you don't usually see zerks on motors that small. Either way, that kind of thing is usually a result of someone absolutely greasing the everloving gently caress out of the bearings; which is also why sealed bearings are better than greaseable bearings for most of applications.
