I've done exactly that myself before, however, knowing what I know now... You get cold bridging through the battens. You've also got to dig into the 50mm pir to run cables in channels, or conduit etc. Easy to put extra sockets in with the service cavity (you can save cable too by going horizontal between sockets). Plenty of benefit for losing that extra inch.

Could you afford to lose nom. 82.5mm inside? 50mm pir, 25mm battens then 12.5mm plasterboard? It'd give you an uninterrupted, nom. airtight, 50mm insulation layer, a 25mm cavity for cabling. You could use 35mm dry lining boxes for sockets and switches. I'm thinking of doing exactly that.

Just sat and worked out I've 8 different external wall make ups here. 1) Render/9" block/1"batten/1/4" hardboard. 2). Render/9" solid brick/render/plaster. 3) Render/4" brick/2" cavity/4" brick/2 - 4" pir/vcl/12.5mm plasterboard or Aqua Panel/tiles 4) Render/4" block/60mm cavity with 50mm Rockwool batts/4" block/50mm battens with 50mm Rockwool batts/12.5mm plasterboard. 5) Render/4" block/render/plaster 6) Render/9" block/render/plaster 7) Render/4" brick/2" cavity/4" brick/render/plaster 8)Tiles / felt / 12mm ply / 4" studs with 100mm roll insulation / 3/8" plasterboard. 4) Is the warmest room in the house. Be easier to knock my place down ?

All a bunch of C**ts! Celts that is...

I seen to remember our Ulster born and bred German teacher saying when he lived in Germany he was complimented on his German for basically lack of a foreign accent.

They're just Geberit copycats.

More ginger, bloodshot eyed, strong smelling and very, very drunk surely?

Basically giving you the old two fingered salute.

Think he extruded a line of triangles on the X axis, then the same on the Y. To get like a "mat" of pyramids.

There's some really clever stuff done with 3D scanning of affected limbs. Enables exact fitting prostheses to perfectly fit the stump or whatever. Used in restorative dental work today. Mulling building a simple scanner here at the moment (uses a mobile phone strapped to it). Could push your hand into algenate or similar, cast in plaster, 3D scan, make a socket etc. There's a lot more to it than that in terms of comfortable fit etc. How about an exoskeleton for your hand with the missing finger(s) "driven" by the remaining ones? ?

I reckon you must have a leaky roof.

Just because you have 100, 90 or whatever mm on the walls doesn't mean you have to have it so thick at the reveals.

The Lidl set doesn't have one in ? I think you mean a riffler file?

Nice files. I won't be contravening the VCRA any time soon trust me!

Bloody kids.

Do you have trouble keeping it "fed"?

What for a Star Wars blaster?

Indeed, I was assuming to do it properly you would need to add MVHR. Saying that there must be cold bridging issues at the floor adding EWI to existing housing stock and no continuity at the ceiling. Is it "worth it" without addressing those other two areas?

Is it an issue if there's a gap between the back of the EWI panel and original wall face? I'm thinking that may be unavoidable anyway if your original wall isn't plumb or the finish stippled, rough etc. Presume the new EWI goes in nice and plumb?

So now I have to figure the trigger (that rhymes ?). In the original box section type it's quite simple as the inside faces of the box side walls provide a bearing surface for the plastic trigger: Shouldn't be insurmountable though. A bit of time on the CAD should have it figured. I'm thinking it'll be a case of cutting a slot with a Dremel in the underside of the copper pipe. It's amazing what you can do with a Dremel and all the various cutting discs and grinding stones, that and some needle files: I need to sort that bottom corner where I overshot with the grinding tool. (Yet another unfinished project ?)

Says the master! ? What system is that out of interest? I presume it all starts with a bottom rail, straight and true? Do you block any existing air bricks? What's the m2 cost on materials excluding labour roughly? Cheers

Steady on now, there's the whole not losing interest / finishing it issues to overcome yet! ? The great thing about this 3D stuff is it's scaleable. So you could make a bigger one for bigger loads or bigger operators even. Good old Fred Taylor! Interesting with your situation hand wise as you could make custom grips etc. A wrist brace might compensate for lack of hand strength to hold the thing and so on.

I did the basic 3D model in AutoCAD and exported as an STL. My lad tweaked it and added the chequering in Fusion 360 I think.

The MK1 handle is printed and the 15mm pipe is a lovely transition fit. Likely a tad loose but PETG is inherently a bit hairy I find, so that helps with grip. The holes in the grip will make it a doddle to drill through the copper and fit some roll pins to hold it together. I might even just use split pins so I can field strip it with just a Leatherman... ? Really happy with the chequering effect my lad managed on the grip. However... The ergonomics leave a bit to be desired. I have really big hands so should really scale this up a bit. I think it looks a bit lost: If I extend the copper out the back, up to a wrist brace, then it pushes into the flesh between thumb and forefinger. I wonder if that will rub and / or leave me with a green mark? It needs to be perfect so it's the envy of other trash pickers like an Ulfbehrt sword... Options are to make the grip bigger, lessen the grip angle maybe or raise the tube higher. As I designed the grip by laying a real trash picker on a flatbed scanner and tracing round the image in AutoCAD I'm happy for a first go. Trigger next I guess.

Should rename you Roy Castle!
