How a reflector gunsight works

[old man emu]

We know that they exist, but did you know how they worked?

No

I'm just usually a SIGHT.  Nev

[nomadpete]

You might reflect on that. Nev

[facthunter]

I've only got a finite number of brain cells, so I keep them for important things.   Nev

My neurologist tells me they don't wear out if you use them.

[facthunter]

Believe me I'm certainly not stopping thinking but you can't get too distracted or you have no organisation or order. Are we stall capable of being decisive? Thats critical.  Nev

I am deciding to refocus on the housing shortage.

 

Could be cured by making a 12 month pause in immigration. To allow the building industry and bureaucrats to catch up with demand.

 

Yeah, I'm  disorganised, but i am critical.

We are short of workers.   A lot of what we're doing is too Labour Intensive.   Nev

Short of workers!

They were here a few years ago , but then , they were expendable. 

My ' painter decorator ' grandson could not get work . He started his own business. 

SO

 He now employs quite a few workers , that couldn't get " normal " work when needed .

Those ' banks ' , with their billion dollar profits are next In line , to be taken down by ,

' people power ' .

It Has started already by mortgagors.  Banding together to lower that interest rate .

Next ' get the ' banks ' financial backers to come to a ( mortagagor ) " co- operative " table directly.

I used to be indecisive but now I'm not quite sure.

We've developed an automatic brick-laying machine here, that should solve the bricklayer shortage problem. It still needs a bit of fine-tuning, though.

Robotically laying bricks is so last week! Now we can 3D print houses 

 

[onetrack]

I'll put my robotic-bricklayer-laid house up against your dubious strength 3D printed house, anytime - especially in a storm! - or on a 45°C day, where the plastic is starting to sag!

I believe it's printed in concrete.

[Marty_d]

Funny thing is, it looks very like my printer only about 300 times bigger.  The printing head moving along the the X axis beam which itself moves on the Y.  Only difference is that my Z axis is done by the hot plate moving down,  whereas that one moves the XY up.

I guess the concrete mix would have to be perfectly consistent all the time too, wonder what sort of additives they put in it.

The tool attached to the Z-axis on my printer or CNC moves up and down while the X and Y remain at the same height above the base of the machine.

Marty - Ahhh, O.K. I didn't watch the entire video that OME put up initially, because I was under time constraints - I thought it was the German 3D printed building that was using recycled plastics.

 

Now that I've had a chance to watch OME's video fully, I see it's some kind of cementitious mortar. I did a Google and came up with this .... it's called "i.tech 3D N" mortar, and it's Italian ....

I wonder if your robotic bricklayer heads straight to the pub after work like the other brickies.

[onetrack]

No, that's the beauty of the robotic bricklayer - no hangovers, no whistling at passing skirt, no sickies (well, maybe an occasional blown hose or a leaking seal), no whinging about having to work overtime, no stopping to watch the football, just continuously laid bricks, that are dead straight and level!!

That bit had me prostate on the floor, laughing.

Can anyone show me a youtoob clip of these machines 3D printing  the reo bars as they go along?

I was wondering how the subject of reflector gunsights drifted to the building industry. But then I realised most people who know what a reflector gunsight is live in a house, so it's all related.

[nomadpete]

It's all just random thoughts, thread hijacks and distractions.......

 

And reflector gunsights don't seem to get much use around here.

[willedoo]

I wonder if the robotic bricklayer can do this:
