As to whether noggins are required: This from the British Gypsum White Book.

Some git will always point them out! On a serious note we cut all the ceiling holes first and managed OK as first time plasterers.

? When all's said and done you know it's all in jest and happily take it on the chin.

Sir Whingealot! Everybody else's fault but yours. Next you need to blame your builder/ neighbour / neighbour's cat and how everyone's ganging up on you. Edit: Sorry, thought the OP was a different person. Is it me or is that vent slightly off centre? (Grabs coat and runs).

Btw, stop pm'ing me please.

So did you not bother asking your BCO? No need I guess now you have the answer you want.

You left yourself wide open, I couldn't resist!

No problems. What size, 3XL & ruined? http://dildo-generator.com/

The plasterer will thank you for it.

@pocster be honest now.....this looks shit! ? No way of moving it to the right, dead centre of the horizontal section?

Like I said offer's there. This is typical: https://cults3d.com/en/3d-model/home/cover-fan-air-conditioner-grille-pour-air-climatise

Could I maybe 3D print you something? Just made my mate an insert to go on his stairs wall for a low down, recessed occupancy sensor. All I'd need is OD and ID of the pipe and some idea of the hole pattern you want. VID-20200512-WA0002.mp4

So you don't like the idea of doing something because it's extra work even when good reasons are given. You're now going to go and ask someone else (the BCO) hoping to get the answer you want? Just ask them in future. Gasket blown.

Let's be honest any local plasterer is likely a mate of your builder.

I have half an idea they, noggins, giving full support, might be required for added fire resistance.

I would yes. Btw, I tried that "Google" search engine thing someone recommended. Effing brilliant tool. I typed in "noggins plasterboard ceiling"... https://www.homebuilding.co.uk/how-to-fit-a-plasterboard-ceiling/

Table saw if you do rip them down I would, with dust extraction. I've spray glued extra strong Bacofoil onto boards before where the foil has come off. Works well.

Something like this. Not the most flattering shot. It'll look better when sanded and painted up with it's "glass" sides and door! Who needs IKEA? ? All the wooden bits connect together with the 3D printed PLA bits at the corners OK. (Though I did break one hinge...I had had a couple). You can just see the door hinges on the front. 9mm ply sheet on the back. I'm a couple of mm out somewhere but I'll get away with it with a bit of trimming! Can't decide whether to let a clear panel into the top. A kilo of RS Pro black PLA coming tomorrow for some reprint bits. Not tried it before, it was just the quickest I could get any.

Dark blue is your 320mm wide bit. What will dictate whether you start with a full board (light blue) on the left is what the end of the board sits on. You MUST ideally have the right hand end of that board on the centre of a joist. Again, imo you want a line of noggins between the light and dark blue:

That size is no issue at all but better with two of you putting it up. In answer to your earlier questions. Plasterboards are shown blue & green, joist bottoms in black. Without noggins, shown red, there is no support under where the edges butt up to each other.

No @pocster, dont get exited: https://passivdom.com/home/ & https://haus.me/

Well...the repaired mower deck is good but the mower gearbox isn't well. Factory filled apparently with (mega expensive) Bentonite lubricant and then the casing sealed with "Permatex 599 Ultra Gray". It changes up/down OK but it feels like something is slipping in the gearbox, it's SO slow. Belt is not slipping. Went off to a neighbours yesterday to rescue the seemingly good gearbox from an abandoned mower that hit a stump and has the front end all bent up. (Social distancing on a 5 acre plot is not an issue btw ?). There were in fact two similar mowers there. Both in a very sorry state. I had permission to turn both over on their bonnets. The salvaged Peerless (American made) "crash" gearbox c/w wheels/tyres removed and back home sitting atop my mower after a cursory jet wash and attempt to pump the tyres up. The nuts and bolts that attach the gearbox have been put in an open topped plastic bag and lowered into the citric acid barrel for it to work it's magic. Of the two salvaged wheels one pumped up OK to 10psi the other is all cracked and leaking like a sieve. Typically as is the case with these mowers the n/s rear wheel was seized solid on the shaft of this salvaged gearbox/axle. (People will bin them just for this). Lucky tbh it's not both wheels stuck as was the case with my mower under the tarp. I managed way back to get the o/s wheel off as it's that you have to remove to access the brake caliper. I still have to get the n/s off of mine, not done as its a mission but I'll have to now. Sods Law the stuck wheel on the salvage axle had the perished tyre. The stuck wheel on my mower has the good tyre! So that was one problem to sort. Sat it upright with copious amounts 3 in 1 & penetrating oil on the end of the shaft hoping it'd seep down. Left it a couple of hours then the stuck wheel came off after some persuasion involving a pair of trestles, two pieces of 4x2, a drift and a hammer. Actually easier than with the gear box in situ. Shafts all emery clothed and lubed. Bosses in the citric acid bath. Next problem: The gear change rod attaches to this lug atop the gearbox (yellow gearbox filler bung just behind): That won't move for me to check the gear changes until I can un-seize the brake which is solid.: It was this that stumped me for a while on mine until a mate in the States kindly sourced me a new caliper from over there. That's on, working a treat and all lubed up on my mower with the now suspect gearbox. Needs to likely come off and go on this salvaged one. The problem is the aluminium caliper and two fixing bolts etc become "one" through the corrosion. Last time I sheared the heads of both bolts I'm pointing to. Again I've lubed it up with penetrating oil and I'll come back to it. Just waiting for the brake to free up! Might end up barrowing it to another neighbour and trying his oxy torch on it if MAPP gas doesnt help. Tried getting the rusted pulley off the gearbox but the circlip just disintegrated and the pulley wouldn't budge. More penetrating oil, more waiting, can't find my really big gear puller either!

Very popular in gay nightclubs.....apparently.

What genre out of interest? I'm betting Hi NRG.
