|Thread: Tools needed to build a 3 1/2in gauge Tich|
I would try to find a design with outside valve gear , valve sitting on top of cylinder.
You will know why when you come to .make minor changes to your inside valve gear .settings.
Being brutally honest here , don't confuse small with easy. And if you do decide on Tich make sure EVERY drawing dimension is right because LBSC used a very special ruler for his dimensions.
A Gauge 1 Project is a guaranteed confidence builder , and it works.
Then build your bigger locomotive.
|Thread: Galvanic Corrosion|
As said, too late to stop the problem now but the 'ignorance' of designers ' to foresee the problem continues.
Entry of moisture /electrolyte down to molecular size is the enemy , permanent contact of oil/grease the friend ..
|Thread: Ambiguous words|
The last word?..............................dying.
|Thread: Wind - trivia|
Correction that should read Menestheus !
Being somewhere at sea off Cap Wrath , MV Menetheseus , Jan '68 , in the worst ever recorded weather in the UK was quite exciting too.
|Thread: Before calculators|
The actual question was part of my 1961 4th form tech drawing papers , now consigned to the bin.
Show how you would make a square of exactly six square inches.
Who remembers how to find the square root of a number with a tape measure, piece of string and a pencil. ?
For example 6.
Draw a line 6 units long, mark , add one unit of length .
Now draw a semi-circle radius 3.5 units.
Draw vertical line up from the 6 mark, measure length where it crosses circle.
Answer 2.44948 units long.
Might come in handy to know one day.
|Thread: Boiler gas burner|
As in full-size , so in miniature.
Do not expect the same output from the boiler with the change you propose.
The paraffin flame was a different colour to your gas flame and the difference will be noticed in the steam raising ability , unless other changes to the boiler design are made.
|Thread: Central Heating Control|
Anyone remember the system Beal were trying to develop , to use the waste heat from a gas boiler to drive a Stirling engine to generate electricity ?
|Thread: UK plans eight new nuclear reactors to boost production|
Even the major news channels keep talking about eight new nuclear power stations instead of eight 'reactors '
as in the first government statement.
In any event , our ( UK ) ability to build reactors, boilers, turbines, etc , of sufficient size or quantity has long gone.
Houses ,warehouses, no problem , real factories no chance.
Where did the 'off-the-shelf ' small modular reactors go ?
We could certainly make coal a 'clean enough' fuel to use economically to make electricity , until such time as the cleaner alternatives could replace it..
However , that is too simple , it is not in the future plans of our leaders for us.
|Thread: Is it really a joke|
All charged by the eight 'new' nuclear reactors we are going to build and have running by 2030.
Ten if Hinkley C is not included plus the 25GW of additional windmills ...............
Any bets ?
|Thread: Why is electricity so expensive?|
Things will get even worse now that National Grid have sold off all our gas grid to an Australian mining co.
|Thread: Central Heating Control|
Phil H1 , a nice ex-Flying Fortress, electrically heated flying suit , is what you are looking for.
Problem is.....getting the rest of the household to wear one as well .
Good luck , and do let us know how it all works out.
We all may finish up wearing one before this energy thing is over.
|Thread: how to make it stay in ?|
A 'loop ' pin in each plug with a 'rubber band' through the hollow axle .
|Thread: Rob Roy boiler; help needed.|
As above , plus the correct sequence of 'assembly' is vital , one wrong step guarantees major problems further down the line.
|Thread: Does anyone recognise this model engine?|
As above plus keep your fingers well away because it looks like everything moves !
