I believe that the beer should deserve an adjective too, strong, tasty etc.
|Thread: DVLA Scam|
This is not a process that I am happy with, the automatic annual extracting of payment from a debit card once you have used it once.
I used to pay my Model Engineer annual subscription by cheque, and each year received a reminder that the subscription required renewing. One year I paid by debit card instead, and since then it has been automatically renewed.
Maybe there is way to opt out of this procedure, but I would much rather that it was configured so that you had to opt in.
|Thread: Old Computers - why do people bother|
I first used Autocad on a Apricot PC, the computer had neither a hard drive or a maths co-processor. The version of Autocad that I used (v2.03) ran off a 3.5" floppy disk. Later on, to speed things up, l bought a second hand 8087 processor.
If my old Dell decides to give up the ghost I will be able transfer the virtual machines over to a new machine that I have installed Virtualbox onto. Although I do not have any msdos virtual machines running, if I had, they could also be moved across.
The main problem with running old programs is the ability to access ancillaries (printers, plotters etc.). There will not be drivers available for modern equipment, and if you still have the old appliances in working order, the new computer will not have the interfaces for them (centronics, rs232).
I am still using a 12 year old Dell computer that was hardly state of the art when I bought it.
The operating system is Windows Vista home. The only program that I have run on this , is Virtualbox.
On this virtual machine I have Autocad 2000 running under Windows 2000. Solidworks 2003 running on a separate Windows 2000, and Lubuntu for accessing the internet and running the few other office and graphics programs that I require (I used to run Ubuntu but later versions became too resource demanding).
This system still meets all my computing needs.
|Thread: Learning CAD with Alibre Atom3D|
To edit a STL with Alibre Atom3D you will first need a program to convert the mesh to a vector file that Alibre can import.
Blender can convert a STL to a DXF.
Both Fusion 360 and freeCAD can convert STL's to STEP files.
|Thread: Painting! There one day, gone the next!|
When paint does not remain attached to an oxidised aluminium surface, is it the oxidised layer that lifts?, or is there a weak bond between the paint and the aluminium oxide?.
|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.
