    You make any like these?
    I am looking for good quality fuel gauge replicas to finish the Hampden panel.
    Cees

    Cees, I can have a go ….:)

    You would need to supply me a drawing in .dxf format with the holes, cut line and graphics generated by an application like TurboCAD/AutoCAD.

    Horsepower is a LINEAR measurement, not an ideal measurement for most machines because they use…
    TORQUE for movement, translated into linear movement by wheels or cogs to a rack.

    NO 😡
    Power can be expressed in angular units as

    Power = torque x angular velocity

    or in linear units as

    Power= force x velocity

    It is meaningless to say that one thing uses power and another uses torque because they are different physical quantities.:)

    It looks like the faces I have made on a CNC milling machine (not this exact one) …..

    Judging by the cutouts, some aircraft with 70’s 80’s instruments? Possibly twin engined?

    I am thinking helicopter, it is like a Bell jet ranger 2.

    I don’t see how the aircraft speed comes in to it ?
    It would suggest that if the aircraft were stationary the engine would produce no power.

    Yes, it transmits no power to the aircraft!

    Power = force x distance / time

    (It is a little less clear in imperial that the lbs are used as a unit of force here rather than mass.)

    All the other clever stuff is covered in the thrust rating of the engine at a given aircraft speed.

    Yes 1 HP = 550 ft lb/second,
    550ft/second is 375 MPH,
    so at that speed the thrust in lb equals the horsepower.

    Attended by 300 Bomber Command veterans, according to BBC Lincolnshire, the event was overflown by several aircraft including “the current McRoberts Reply, a Short Stirling bomber”. Say no more…….

    Any pictures?

    Just pulled one out of a switch and it was 6-32 UNC.

    (In fact the label has the three circles on it signifying the Unified thread standard supposedly linking Britain the US and Canada.)

    I don’t doubt this, but member smirky in post #567 does, hence my query!

    Rob

    On the contrary, I was commenting on post 565 where a member stated as a fact that the seats were inert, before going on to say that he found it surprising.

    I found it incredible.

    The police were concerned that the ejection seats in the wreckage might still be live. However it turned out that they were inert. I found that surprising.

    I find it incredible, what is your evidence for this?

    There has been as much balls talked about the seat as everything else.

    I don’t think we should be so dismissive of the Sun, it is simply echoing the questions that I have overheard people asking today and that after all is what sells papers.

    The underlying question with the benefit of hindsight is a valid one and I don’t expect that manoeuvre will ever be repeated in such close proximity to a busy road.

    Rather too new – it was a prototype with serious design defects.

    On the contrary, I agree with Moggy.

    Mr Humphries was only posing the obvious questions that public opinion demands.

    It was up to the interviewee to refute any inaccuracies, to add perspective and to respond convincingly to the devastatingly clear logic behind the question (i.e that the technical causes of the tragedy were immaterial to the question of whether the ‘stunt’ should have taken place over land).

    Just heard the BADA representative being questioned by John Humphries on the wireless – not a good performance.

    Are there questions to be asked and answered as to whether this ‘stunt’ should have been performed over a densely populated area? Well obviously, but would this bloke admit it? Nope.

    I hate that word ‘stunt’ it is so disrespectful.

    by and large things carried on much as before

    I was not around at the time but I thought that the Farnborough tragedy lead to significant safety improvements such as not flying over or towards spectators.
