|Thread: My really awful week!|
A crystal set.
|Thread: How to upset the neighbours!|
There is a company that is producing an updated MGB. It seems that it produces to an electrifying experience.
|Thread: Scale gauges|
The origin of having a set of standard gauges was introduced by a toy manufacturer in 1891 (Märklin ) . They were gauges numbered 1 to 5
Number 1 gauge = 45mm
Number 2 gauge = 54mm
Number 3 gauge = 67mm
Number 4 gauge = 75mm
Number 5 gauge = 120mm
The only one that has remained to its original dimension is gauge 1.
More likely that someone who has chosen to build with a correct scale/gauge ratio has decided to build a model of a prototype for which no drawings or castings are available. There is a lot of extra design/drawing work involved in producing a more authentic representative of a given locomotive from a published standard design. For example see the current ME series of articles by Doug Hewson on updating LBSC's pannier tank locomotive "Pansy".
|Thread: Electric Cars|
I foresee five years from now the uptake of electric vehicles being no where near the figures being currently predicted. In fifteen years nearly every new road vehicle will be an electric.

|Thread: Coal Merchants Wagons|
I remember as a lad, seeing in the windows of coal merchants, large scale models of railway wagons (they could have been 7 1/4 inches gauge or even 10 1/4 inches), painted in the livery of the company. After a brief search on the web, I have not found references to these models. Were they a wide spread phenomena?. Does anyone know of any that still exist?.

|Thread: Making a Start in FreeCAD|
Onshape is free to hobbyist the biggest restriction being, that the free subscription only allows public data. in other words anyone has access to your work.
FreeCAD has the advantage over Alibre, Fusion and Onshape, in regards that , you do not find yourself waiting for the other shoe to drop, and what has been "free" up until now, you are suddenly charged for.
|Thread: DraftSight no longer free|
Maybe not. I use Onshape rather than Fusion 360, but the free use for non-commercial users is pretty much the same deal. I do not believe that model engineers, that are predominantly older chaps (Not being a sexist here and I realise that one of most accomplished model engineers in Britain is a woman) are the principle targets for these free arrangements. The vendors of these products are trying to win over young people with design aptitude, being well aware that once someone has invested time and effort into learning a program they have an incentive to stick with what they are familiar with. These youthful users may well be in commercial positions later on to specify the software the companies that they are working for will be using.
|Thread: Why a round bed?|
Tried calling Guildford 153, but so far no response. I wonder if the M.O.D. still have some in storage that they would be willing to sell off at low cost.
|Thread: Chinese Lathes|
Sorry, I double posted.

Pregnant lathes!, so you would never have to buy another one. Pity though that they would be out of commission for 9 months.
|Thread: "Screwing" a car round a corner!|
The late James Hunt former Grand Prix world champion, owned a Austin A35 van. He was quoted as saying that it was his favourite road car because he could drive it at the limit without driving illegally.
|Thread: Myford colours|
I am certain it is not light Admiralty grey (Naval light grey), as one company that I worked for, produced equipment for the Royal Navy that had to be finished in that colour. It appeared to me to be a pale blue, though none of my colleagues could discern this. The colour though was a lot lighter than the finish on the Myford ML7 lathe that I had to occasionally use.
|Thread: Machinery Directive and CE marking|
I did find the current topic a little worrying, as my last completed project was what to do with a 1970's vintage Black and Decker electric drill.
|Thread: Rulers - my pet peeve|
This one came out of a Christmas cracker, I keep it in my wallet, it gets a surprising amount of use.
|Thread: Logging in to forum|
I find that regular logging is a good practice, otherwise I tend to forget my user name and password.
|Thread: Testing for isolation|
I once manged to lay a spanner across the terminals of a 12v car battery. Lucky I was not holding on to it at the time. The cable insulation immediately begun to melt away. With the advent of the newest 48 VDC vehicle electrical systems, I should imagine that result of such a short would be more spectacular/lethal.
|Thread: Gatwick Drone 'Attack'|
Drones could provide a much more cost effective way to keep track of the scum bags than the helicopter.
The drones now appear to have moved on to Heathrow.
