Squeak and I are designing and making a Museum Donation Box in the form of a mechanical diorama, with cars, tractors, boats, tram, train and plane and various other moving parts. I will paint the Heinkel tomorrow, too tired to start now!

Photobucket has changed its site and now nothing works, will try summat else:

they won't let you hot link to images.
you have to download it and then attach it to your message like this:
-
Cheers Jim! It used to be easier, and I tried lots of different ways (as suggested on the Attaching photos thread, but I can't get my pc to do downloads!
-
Have been trying again: All New Photobucket now has two sets of commands, one set is in blue (i.e. Links) and includes "Download". Helpfully NOT, these are not active and serve no purpose at all. The other set of Links includes HTML, IMG, and others but no explanation as to which to use so I tried to embed each one in turn and NONE of them work. Well done Photobucket, you really know how to waste people's time!
So all I can do is post 4 links from the title bar
Painted, front view (match stick for scale):

I bid three pence for the little wooden model!
You should talk to Dave Hambleton about Dioramas. He wants to create one of the Trojan works for the Trust's display. I love things like this and could happily return to model making if I become house bound.
-
3 pence? THREE BLOOMING PENCE?
It took me several hours to complete that model....2 pence is more than enough, do you want it wrapped?
-
Progress as of "Tools Down" at 7pm:

Its coming together Marcus.
Isnt this where Barry usually comes in and says, you don't wanna to do it like that , you wanna do it like this with a CNC machine and computermobob software?
-
Cheers Bob, photos don't really do them justice as they are so small that I have to get in really close, and then you see all the imperfections which you do not notice from normal eye viewing distance!
As for CAD/Cam etc., the whole point of this Diorama is that everything in it is a bit lop-sided, wonky, tumble-down and oddball, for instance Sleepy Hill Station has props to keep it up and it will have a palm tree growing through its roof! A giraffe will pop its head out of the Coach's roof. programming it all would take far longer than getting on and making them!
Besides....I LIKE making them!
-
"the whole point of this is that everything in it is a bit lop-sided, wonky, tumble-down and oddball,"
If only I could get away with saying that to my customers! ;D
-
Yup! That's why this project is so much fun. It was odd though, having to deliberately make things "wrong"!
Most of the vehicles are "cartoonised or wonky" real ones...The loco is a mix of "Gazelle" (at Kent and East Sussex Railway), but with the cab of a Black Hawthorn iron works loco, the coach is a British European Airways AEC Regent 1 1/2 decker, the car is very loosely based on an Austin 7 Chummy, and the glider is based on Sir George Cayley's glider which was the World's first ever Heavier-than-air craft to carry a person aloft.
-
I've given up on believing who was the first to do this or that in aviation history, its a mine field. I'm still fairly convinced that Gustave Whitehead flew in 1901 before the Wright bros though. There were eye witnesses that came forward some time after the event.
-
It all depends how you specify it, but it is VERY hard to nail it down, but I believe these are beyond doubt:
First to get human aloft lighter than air craft : Montgolfier Brothers, hot air balloon
f t g h a : heavier than air: Cayley glider
ftgha ; powered: Clement Ader, Eole
ftgha ; powered sustained controlled : Wright Bros
There are all sorts of other balloon firsts for animals, then powered balloon, then powered dirigible balloon (i.e. steerable!).
Then for heavier-than-air there were various glders and then powered planes without 3 axis control.
Plenty of people flew powered planes, and Maxim's would have flown but was deliberately held down by its rails.
The Wrights were not the first to glide or fly powered craft, their "sustained" first flight was less sustained than other flights which did not have 3 axis control!
The Wrights are defined as the first to fly powered, controlled (i.e. 3 axis control) and sustained. However, many claim that the Wrights early flights were downhill, and/or in strong winds (i.e not capable of taking off or flying sustained without slope or wind assistance!)
The Wright's have largely been credited as the "first" because they had mechanisms to control all 3 axes, but many modern craft fly fine without 3 axis mech....fighters (computer flown) hang gliders and micro-lights and various others.
This means that the 3 normal definitions (powered sustained and controlled) are NOT all necessary, therefore arguably Ader and others DID beat the Wiights.
The Wrights win by the right definition, but the right definition is wrong..... :)

Nothing finished yet but starting to look colourful:

The Rowland Emett style train and the Tram are now pretty much finished:

Great "little" project. The bloke in the bath, is he modelled on anyone we know? ;D
-
Cheers Rob!
Not modeled on anyone, but could be named after some people, like
Spike Milligan, who had to endure a Jeep Bath (senior Officer got first use of the water.....!)
or perhaps
Alexander Thynn, eccentri Marquess of Bath:

Saw an autogyro or is it giro as my phone tells me ? Over the beach today - I don't think I have ever seen one before - great fun and fast !
-
Yup, Autogyro (UK) Gyrocopter (USA). Great fun, always wanted a go, see them over Camber Sands occasionally. Celebrated Autogyro builder and pilot (inc 007 fillum) Wing Commander Ken Wallis died last year, top British boffin. I considered an Autogyro for this Diorama but already have 3 flying things listed.
-
Was driving past Rochester aerodrome, Kent last week and an Autogyro took off right over me, great sight!
Now getting to grips with the mechanism.....<<Stanley Unwin; "Deep joy, counter-rotatey mechanold with Ball-Beary smoothly go!" :

Looks like a planetarium at the moment
Solly cistern in big Unifold. To goldly bod where humouman begone foretime, oh no!
The Autogyro, Microcar of the air?
-
Great micro car analogy: small, simple, light, cheap, fun but dangerous if you take liberties.
Good Planetarium analogy, yup a bit like that or an Orery. The inner and outer vertical shafts will have pulleys and belts to 2 vertical counter-shafts. The handle will be on a shaft with two worm gears, these will drive two spur gears of different sizes, one on each counter-shaft. That will ultimately give two "layers" of model going clockwise at one speed and two more layers going anti-clockwise at another speed. The models show transport by water, rail, road and air.
Once that is done it will be time to get the "layer" base-boards made and fitted (the basic structure of the hill part of "Sleepy Hill". THEN it will be time to start making the cams and bell-cranks to work the non-transport models and just hope not too many mechanisms snag on too many other mechanisms! Exhausting work, brain hurts!
-
Three R's in Orrery Marcus. Sorry to be pedantic , a lot of them have passed through my hands over the years.
-
GODDAM SPELL-CHECK! I wrote it with 3, Spell-check queried it, so I altered it! I HATE spell-check, especially as it is ALWAYS set up with American mis-spelled versions of words!
-
My iPhone is frankly ridiculous , as I am away a lot recent contributions have mainly been via this channel . When I re-read some of my sentences the whole thing is quite different to what I typed in , it doesn't just respell words it actually will re-write a section with TOTALLY different whole words and phrases . I emailed my office today to mention Much Wenlock Pharmacy and it was hilarious what it made of that !
-
Well come on then, tell us!
If I recall correctly, the first Modern Olympic Games were held at Much Wenlock and included Poetry and Flower Arranging. I don't even know where it is.
-
There's the rub Marcus once I corrected it my phone seems to remember so I can't remember ! Much Wenlock is in Shropshire , Wenlock Edge , Long Mynd, Ludlow,Shropshire all very Enid Blyton Famous Five - a really beautiful part of the country which has recently become my favourite county
-
Had a look on Google, near Telford, not an area I have been to, even though I have traveled a fair bit.

Talking of spelling errors, I received this email from Jean today.....
"Not only have I been laid low by some anti-inflammatory drug prescribed to me but my email jean@rumcars.org has ceased to function. I am hoping you may get this email to ask you and Christ to keep the RumCar flag flying until I can get things sorted out."
Hilarious! Either Jeans thinks I'm better connected than I am or she is revering Chris a little more than she should!
Poor Jean, she must be feeling rough to have made such a mistake.
-
Miracle cure needed!
Get well soon Jean!
It makes me laugh when the government goes on and on about education and teaching kids to spell. My answer: make it illegal for computer companies to sell computers in UK with American spell check software; by Law the software should be supplied translated to English. I have analyzed my speling and recognyze that it is getting werse because Spel cheque keeps querying English spollang!

I nearly bought an old forge north of Craven Arms on the main road through the counties behind Clee Hill. It is very Rural and to the west you have empty Marches into the Welsh Highlands. A great place to do up cars and have adventures. Trouble is because it is quite empty there are few folk to be friends with and a fair old step from anyone.
Interestingly there is an enclave of Valesman up near Longden/Wenlock as it is very like the Vale used to be before they started building everywhere and the townies moved in. So I was repeating a thought process of the older countrymen who did not like what was happening. As it is I will stick for the moment. But the unrestricted building is getting very bad and the area threatens to become like one continuous outer suburb. Did you know that up into the '70's Wiltshire was so sparsely populated it ranked as the same risk as Scotland for insurance! Not anymore, you can hardly move.
-
Living a few miles from Craven Arms Al you make out that we live in a wilderness I think its very rude to say it is quite empty in the Marches I do not know where you get you information but that's have no more of it!!
-
If you lived here you would probably relish your density of population there. The South East is filled and it seems we are next to be forced to be overpopulated. Probably as I can reach London, Bristol or Birmingham in an hour.
There is a difference between underpopulation and rural. I like rural, its where I grew up, but it now only exists in the far corner of the Vale (Actually the Vale itself, part of Oxfordshire who annexed it from Berkshire, and than added its name to it so it sounds a nice place. The rest is in Wiltshire. If you cannot see Uffington Castle, you cannot be in the Vale. Idiot Governments.)
I apologies for liking where you live.

Have just completed speed tests for the counter-rotating mechanism using a cheap plastic worm and wheel set. I have to plan for people turning the handle as fast as possible so have now settled on 10 : 1 reduction for the top two levels (one not yet in place) and 20 : 1 for the counter-rotating lower two levels. It will all be hidden inside Sleepy Hill, but I could not resist attaching the Tram model for this film:

Progress video. mechanism disconnected while I start to build the four levels, here it is with the first two roughly in place and turned by hand. The railway level has all 3 models, the canal has only 3, and there will be two more.

The hammering sound is someone making a boat outside, NOT the mechanism!
