Shedlads, I'm out of my depth.
I need to glue some perspex parts together, so was looking at some acrylic cement to get a strong, airtight join.
But I wonder, will poly cement do the same job? I already have loads of that from my little toy soldiers. I don't have any spare material to test it on annoyingly.

You'll need a proper acrylic cement, unless you don't mind the glue causing the perspex to get cloudy. Otherwise you could use superglue to do the job. Poly cement won't do it though.

Depending on what condition the teeth are in, you could probably polish the rust off and it'll cut soft wood, but I doubt it's worth it. A £10 saw from B&Q will be way better.

If the teeth are sharp and straight then absolutely. If they're not then still probably.

It's too rusted for the teeth to be sharp. Saws are sharpenable, but it's not something I'd suggest tackling unless you've got a reasonable amount of experience with sharpening chisels and plane blades. Probably not worth the effort TBH. The rest should come up fine with a bit of elbow grease.

Reason I ask on a glue board is that I've looked into netting for the window on my flat

uPVC has reasonably good chemical resistance, so you can use white vinegar, isopropanol or even dilute acetone to remove any adhesive residues from window frames. If you need to stick anything to a painted surface, use 3M Command Strips.

This would be the case, painted wood you see. Although I'm not sure 3M have what it takes as it'll need to hold magnets, mesh and metal bits over a 52 x 38 space. I use the hooks internally but for a window that could create some force if the winds is pushing at the mesh.

Check to see if you can see where those bits come out underneath. If you can, get the cheapest thing that'll fit the spacing. If you can't, then you have a top fixing which means you'll need to shop around to find a suitable seat.

Though if you're renting, then it's likely wear and tear which means it's on your landlord to fix it.

When this happened to mine there were big plastic thumbscrews on the underside that were fused closed through age/piss and they had to be undone with pliers which managed to chip a sharp piece off the porcelain which fucked my thumb up. Hopefully that knowledge helps.

Properly cured polymer clay is basically PVC, which has excellent water resistance but relatively poor resistance to oils. In the uncured or partially-cured state there'll be a lot of filler material and unbound plasticisers that aren't necessarily stable in water.

OP here an update: the plastic putty absolutely did not withstand exposure to regular warm water, and despite hardening like a rock, softened and came away in bits.

I've now been arsed to go to the shop and buy a proper waterproof glue and a caulking gun.

Lesson learned, don't be lazy when it comes to water and heat tolerance.

Lamp fitting wattages used to be important in the days of incandescent bulbs which put out a shitton of heat. If you put a 100w bulb in a 60w lamp, it would get very toasty in there and possibly melt or catch fire.

With LEDs its a bit more complicated. If you've got a lamp with a separate transformer putting out 12vdc, going over the W rating could end up burning out the transformer.

But I'm guessing this is probably a mains powered lamp you've got, in which case it's hard to give a good answer as the efficiency and heat output of different types of LED bulbs varies hugely. I would say that as long as the lamp is fairly open with space for air to circulate around the bulb then there should be no problem with it.

Why would you take the switch connection from the low (switched) side of the solenoid? Are you trying to build an oscillator this way, to make the bell ring?
Rule 3 of electronics: Amplifiers oscillate, oscillators don't.
At least be prepared to put a capacitor between B & E , and even then, be prepared for the bastard thing to just fins a bias point and sit there burning power in the transistor until it fails.

Because it's less of a pain in the arse to wire it that way when you take into account the physical construction of the doorbell and the existing wiring, and because it's a doorbell not a finely tuned SMPS.
Even if there's enough capacitative coupling in the cable to cause it to oscillate it should act as a charge pump via the B->E junction of Q1 until the base voltage gets pushed far enough below the switch on threshold to kill any oscillations.

sage because the proper answer is to replace the button and/or cable rather than mod the doorbell to work for a bit longer with failing wiring.

The joy of electronics is that it doesn't give a damn if you're trying to build something trivial, the same rules still apply.
I think you should reduce R1 (possibly to zero), or you'll be pissing away volts across, and power into, the transistor. You want the transistor on hard. As it turns on, the voltage available through the switch will drop, as more volts appear across L1. No need for a current limiting resistor on the base, by the time the transistor is on enough to pull the bottom of the inductor to 0.6V or so, it'll all self-limit.
Bear in mind also that 9V batteries are shit. Alkalines start out at 10Ohms, end up at 1K. Make sure your doorbell solenoid won't just drain it in a couple of uses. A battery holder with 6 C cells has vastly better performance if you can find the space. (or 4 C cells, given that the pp3 will be wilting pretty much from the start).

When carrying some furniture through to the garden, I left a ding in my stainless steel fridge-freezer door just a few mm in diameter. My girlfriend says no sane person would notice it and not to worry, but I hate causing damage and not at least trying to fix it, and it is visible from a very low angle. I'd estimate it to be 3mm - 5mm and not maybe 1mm depth at the deepest point.

What could pull out a tiny dent like this? The other side isn't accessible to pop it out. I have a feeling a standard toilet plunger would be too large to target the dent.

Would heat work, with the consideration that there's a freezer going on the other side?

I'd obviously prefer not to spend money on an expensive gizmo or cause more damage.

Small dents like that are really tricky to pull, because there's less surface area and more plastic deformation. Your best chance is with a PDR tool (about a tenner from AliExpress).

Lads. Something happened to two of the carpet tiles in my current flat, and I'd like to replace them rather than lose my deposit. I carefully took one up and found no manufacturer identification, just the number '50718' printed on the back. Googling "50718" "carpet tile" gets me sweet fuck all.

I'd rather not alert the landlord of this, so before I go asking for new carpet tiles from them, can anyone help me ID this?

It must be fixed to a sturdy wall (not just screwed into dry wall without anchors) if you want it to be solid, but if can be sure no toddler will try to climb it and you follow above given advice about heavy at the bottom, light at the top you'll be ok. Pretend its Jenga and the damn thing wants to topple over, basically.

Also bear in mind that, when fixed to a wall, there'll be little flex in the structure. When that's absent, it can flex however it wants. Even if you keep your lead bar collection on the bottom shelf, you still can't use the top shelf to store heavy things because the structure is a bit flimsy.

What's the trick to getting a bedframe that won't fall to bits after a few years? I'm quite 'heavy arsed' and a giant so breaking beds is something I do. Low-beds are maybe one solution but there are a host of reasons why people don't sleep on the floor.

I'm specifically annoyed with the problems slats can give. Big Bear knows full well that slats break, bend or, in the case of metal, will just come off the frame.

It doesn't have to be nearly a grand as >>2838 mentions, but a good bed costs money. You can build your own if you're handy around wood, but if you're buying one anything which comes as a kit with fancy nuts and bolts to screw it together is, very likely, a bunch of tosh. The metal frame shown in the picture, for example, looks exactly like the kind of trim you find on a tube framed bit of cheapo nonesense.

If you don't want to go DIY, find a (semi-)local bed maker and get something that's made of squares and screws together with plain wood screws. Then apply >>2839 and reinforce it; the entire bed should, if at all, move and flex as a single unit. Any play in the component parts will get stressed incessantly as you toss and turn during sleep. When reinforcing, bear in mind that you put more pressure on the bed around your hips and mid-torso than your head or feet both when sleeping in it and when falling into bed or sitting down/up on it, so the centre area is particularly important to reinforce.

I'm no Big Bear at *mumble* over 15st, but even I learned that slats are wear parts. It does depend on your mattress and how well it spreads your weight across them but having a half dozen or so spare at all times is a god sent. Check your bed every 3 months or so to replace slats that appear less than perfect. You can even do a rotation, move slats from near the end of your bed towards the centre and get some more use out of the centre ones near your feet for example.

Torx is close to mathematically optimal. The only real down-side is that a) it's quite hard to distinguish the sizes by eye and b) it's quite easy to chew up a screw head by using an under-sized bit. It's perfect for manufacturing, but slightly annoying during servicing and repair.

I've probably had the least grief with internal hex, but it's not suitable for a lot of applications due to size constraints. External hex is still probably the best option for tough environments subject to abrasion or corrosion, but those buggers owe me a lot of knuckle skin.

"Cross-head" is an absolute shit-show, because there are so many almost-compatible standards.

Pentalobe can fuck off. Tri-point can fuck off, come back and then fuck off again.

My favourite is the Pitlock, which is the only removable security bolt I've used that is actually secure. Totally niche, but invaluable if you need it.

I should qualify that I accept that many other solutions may be technically better, but the availability of specialist bits is a huge letdown for me. You can't really bodge a torx like you can a posi/phillips or slotted, and fiddling with often fragile driver bits is a real turn off - ironically any sort of torque applied through a torx bit will snap the bit easily. Maybe I could just buy more expensive torx bits, but fuck you - I've never once snapped a Philips bit.

In my experience those gas fireplace things work best. You know, like your nan used to have with the three ceramic panels, but on wheels. They kick out more heat than leccy ones and they're not as bad for emissions as just burning wood.

I think they make portable camping ones, I've seen it on that YouTube channel where that madlad Canadian fella sleeps in the back of rental vans for a laugh.
