Petra in Jordan. The scale is breathtaking

The reason why I think it's a bit cheap is because when you compare it to an SMLE, it just is. L sights (or ones that don't work too well), stamped barrely bands, issues with floating barrels bending, magazines not seating properly and so on and so on.

Our group has several No.4s and there isn't one that doesn't have some issue with it. I adore both my No.4s but they're just not as good as the SMLEs that we have.

I'm rather partial to the P14, too, even if it is half way between the two.

Re: Lee-Enfield.

Your "L-sights" are a wartime expedient, which should have been replaced with "milled" Mark 1 sights at some later time in their history. I will send some, if you wish.

Better still send us the rifles and we will refurbish them. That is our business.

That's very kind of you but I must keep it wartime standard - it's used for re-enacting.

What's your company?

I've PM'ed you.

How about 'Flip' then

Once it gets to the operating location, it's tipped over like this:

So why doesn't the lifeboat flip as well then?

My guess is, in an emergency it is dropped and self rights and then the staff jump for it.

I would guess its safer that way.

This may have already been posted but....

I always thought that this was a great piece of engineering:



A great high speed video of the insane flex in the thing when it fires:

Don't fire it to close to your car, this is some muzzle blast:

Why? There's nothing clever in it and it's reputedly not even a particularity goof rifle.

If you want a clever weapon system try this or this.


The first working caseless ammo design.


Designed to use a very high velocity flechette round which had an extremely flat round trajectory - the round hits where you aim.

Probably not that doesn’t look as though it would self right its probably just a transport craft, the life boat will be in the white drum on the top level.

I think the lift raft at the top was designed for normal usage and not that.

It's mounted to high to be any use in that set-up.

I love this thread!!!!!!


So many to choose from but i thought i'd put one up a little different to everyone else's....




And one at impact, amazing the energy transfer....

Taisun. The world's strongest crane.

Here it is lifting a 14,000 Ton Deck Platform onto the Rig Hull in a Chinese dock. Not its heaviest lift though as it was tested with a 20,133 metric tonne water-filled barge. The heaviest lift ever by a crane.

Bugatti Veyron engine.



And gearbox..May not be cool, but an amazing engineering achievement. 7-speed Dual Clutch DCT gearbox engineered and built by British company Ricardo.

How does the dual clutch work and how is it better than a single? Is it the same as a DSG gearbox?

407 BHP on the first dyno run in 1967. Up to 500 BHP within a few years. Pretty amazing figures for the time.

Always a favourate of mine, simple design but worked very well.



Such a shame she never saw action....although I am sure most captains of the day would have run a mile.

Ah, HMS Warrior. Superb end to a day out and an eye opener. Never realised it existed given its construction.

A cryptic one.

The rocket test site on the Isle of Wight?

That's the fella, A lot of history behind it and something called Prospero came out of it (well, not launched from there).

http://en.wikipedia.org/wiki/Prospero_X-3

All related to this



Fascinating program on R4 last year interviewing the people who worked on it.

[Shar2]

They also did a bit on the Coast series. They found that Prospero was in fact still working, quite impressive. All brought to a halt by the government who said they couldn't afford both the rocket program and Concorde, and as there wasn't a business case for satelites at the time Concorde won.

Also, maybe not the coolest thing ever but thought these Formula Student uprights were pretty cool when I finished designing and building them.

And I hope you added an extra bit at the lower wishbone pickup to put it in double shear, rather than single.

No single shear on the bottom was fine, we upgraded from 8mm to 3/8 bolts after the first test after that no problems.

The judges generally dont like single sheer however FEA shoes double sheer is not necessary. I don't recognise Nobody's uni but they are not the only people to use single sheer on the uprights.

Trying to fix a a rose-joint at the bottom of a upright is horrendous if designed to be in double sheer.

i went on holiday to the ilse of wight when i was maybe 11-12 yrs old. the standout memory is of finding one of the doors to those structures open so me and my dad went in for a nosy. the rotten decomposed corpse of a dog [i presume] on the stairwell made for a hasty exit and just a little bit of sick....
