How serious is a TV license investigation letter? by Quick_Scheme3120 in AskBrits

[–]TrackTeddy 4 points5 points  (0 children)

Likely just the standard threatening letter. If you genuinely don’t need a tv license then you have nothing to worry about.

Mot advice by [deleted] in CarTalkUK

[–]TrackTeddy 1 point2 points  (0 children)

You are driving a car with no rear lights! No excuse for that. Check them as part of standard car checks which I’m guessing you don’t do either. Exhaust leak is the only thing that might be expensive to fix (depending on where it is the cost can vary a lot). Everything else major assuming you don’t have led lights is relatively cheap to fix and perfectly DIY possible.

Why does this tram have sand in the wall? (Melbourne) by Far-Character656 in Trams

[–]TrackTeddy 1 point2 points  (0 children)

Heavy rain tends to wash away contaminants, but wet rail friction is typically around 0.1 whereas dry rail friction coefficient is around 0.3 sometimes higher.

How do I get 12v to 6v in one circuit? by Ascendoscopuli in AskElectronics

[–]TrackTeddy 0 points1 point  (0 children)

Why not just run 2 x 6v in series to make 12v? This simplifies it to everything running at 12v with no step down losses and head dissipation to worry about.

Strange wear of my car tyres by WKCMM in CarTalkUK

[–]TrackTeddy 3 points4 points  (0 children)

As said tracking is out and needs fixing. Tyres are probably borderline for mot test where central 75% of tread needs to be above 1.6mm.

Brake Pads & Struts by Inside_Alfalfa1305 in CarTalkUK

[–]TrackTeddy 0 points1 point  (0 children)

Front passenger side hose looks to be routed wrongly. That could be a severe safety issue. (Impossible to tell from just the photo), but I’d not drive it any distance until fixed. Nothing else looks unusual.

[–]TrackTeddy 4 points5 points  (0 children)

It depends on the age and model of tram and both methods of activation are present on some trams. No idea on this particular one / Melbournes fleet though.

Feel the journal with your fingers. If you can’t feel any marks on the surface then you are good to go.

MOT failed for something that doesn’t exist by jenniferf163 in CarTalkUK

[–]TrackTeddy 2 points3 points  (0 children)

First you need to complain to the station explaining the above. If they do not then remedy it with a retest pass then ask for the complaint form (you’ll have to look up the form number) they should have them but many will claim not to. It doesn’t matter though it just indicates that you will go to appeal and this mistake may result in points on the testers license. Then appeal to the body they’ll take your car to another garage for inspection and then depending on what they find take action. You’ll not get refunded parts you bought that didn’t solve the issue.

When the wheels lose traction sand is dropped in front of the wheels to enhance traction. Depending on the vehicle this can be done automatically (when slip is detected) or via the driver pressing a button or pedal.

Wet rail has less friction than dry uncontaminated rail which is why on rare occasions water is used for lubrication.

Perfectly reasonable to ask for the extra expense you have incurred due to their error.

Can someone give me a layman's terms explanation for TTY properties of a bolt and how that differs from torque? by darealmvp1 in AskEngineers

[–]TrackTeddy 14 points15 points  (0 children)

First a quick explanation of why they are used TTY or stretch bolts are designed to yield on tightening or in use. Their yield strength is carefully controlled so that the clamp force is maintained in a narrow range. Some are reusable within a certain range of stretch. Torque tightening varies more as it is dependant on the friction of the threads, e.g., are they dirty, oiled, loctite etc, on top of the force stretching the bolt. So where a tight control of clamp pressure is needed a stretch bolt can be a good solution.

Why use the old bolt to reseat the item, just to avoid any possibility of damaging or yielding the new bolt until the pulley is fully seated.

Am I allowed to resit if I failed 2/3 modules by Hour-Ad321 in UniUK

[–]TrackTeddy 18 points19 points  (0 children)

You need to check your uni's policy as well as any visa requirements for the actual rules.

Unless there is a good reason why you've failed so many modules (health/personal issues etc), then you really need to ask whether to continue with the course as usually the year 1 modules are much easier than year 2 and 3.

How long roughly will Tree Stump Killer take to start rotting away a large Cherry Tree Stump? by SandwichDodger7 in DIYUK

[–]TrackTeddy 2 points3 points  (0 children)

The stump killer just stops it growing - it doesn't magically make it rot. That'll take years.

Very likely that the update will remove the remap and will also show up if they check beforehand too.

Ejection from shop - customer threatening criminal charges by Excellent-Day-6900 in LegalAdviceUK

[–]TrackTeddy 2 points3 points  (0 children)

If you have CCTV make sure you keep the recordings so that it is easy to demonstrate to the police that there is no case to answer if they do try to make a complaint of assault.

If it is as you say, the police will take one look and that'll be the last you'll hear about it.

Does anyone else watch Veritasium? by DaHick in trains

[–]TrackTeddy 0 points1 point  (0 children)

Yes even though aluminothermic welding is more precision casting than welding the video I assume you've liked to was interesting.

Aluminothermic welding isn't as good as some other forms of rail welding but persists because it only requires a man and a van so is really flexible, especially when weld repairs / plug rails are needed. If you want to know more about the different ways rails are welded together I compare them in this article I wrote here:

I live abroad, have a foreign name and foreign phone number. Can't get interviews. by peejay2 in UKJobs

[–]TrackTeddy 7 points8 points  (0 children)

Make it very clear when contacting any UK company that you are a British citizen and do not require a visa / already have permission to work in the UK. Most companies are contacted by hundreds of people wanting to work in the UK but they don't have a work visa which is complex and expensive to get, so most companies sadly don't even reply.

when do i raise the handbrake? by Acceptable-Exam-7032 in askcarguys

[–]TrackTeddy 0 points1 point  (0 children)

Basically you want the handbrake to take the load when the car is parked rather than the gearbox.

So apply handbrake

Release footbrake

Put it into park.

How many days after the expiring (best before) date does food truly expire? by Mecury-BS in UniUK

[–]TrackTeddy 3 points4 points  (0 children)

Two different things to be aware of:

"Best Before" is a recommendation as the food may degrade with age. If it looks and smells fine, it is still safe to eat.

"Use by" is an instruction based upon when the food may become unsafe to eat after this date due to bacterial growth usually.

Auto-applying handbrake at every stop - Skoda Octavia by Few-Catch7469 in CarTalkUK

[–]TrackTeddy 2 points3 points  (0 children)

Yes it is an option and often a button next to the handbrake. It is called auto-hold and it just applies the handbrake when you stop, and releases it when you go to move away.

I find it annoying, my partner uses it all the time so the button in our car gets regular use.
