wheel size less a problem on its own, but if requiring something with suitable valve gear then it is more difficult.

A Southern Railway N class chassis with the leading set of driving wheels removed may be an option. Wheel diameter is similar, 5' 6" for the N, 5' 6" for the H. Not sure about the wheelbase though.

Wow G and H classes - just what I need for my P4 layout.

 

I am in the strange position of having the wheels already (from the old Mike Sharman range) so over the next 4 months when I am at home, self-isolating, will have to start on the chassis.

 

 

(Once I can persuade the other half I really need the bodies :))

I want to do an F class but can't find either a drawing or dimensions apart from wheel size and wheelbase. I think it is similar to the E class. Certainly looks lke same boiler and front end. Looked at the preview of a drawing on HMRS, but looking closely I think it is actually an E not an F class. Will probably do the E class next, then when I have enough info on the F , I can use it as a start point.

Hi,

 

My late father used to drive F class locos for London Transport. He always referred to them as "the big engines" and the E class as the "little engines".

 

When I was little he took me into Neasden (it was the late 1950s, can't imagine that happening nowadays!), and I couldn't see the difference. He pointed out the wheel arrangement, but as far as I remember  body wise the only real difference was the F class had a bigger bunker, and seem to remember it stood higher - but I was only 9 at the time!,

 

There used to be a F class body shell kit available way back - GS models. I think it was RThompson of RT Models under a different guise but could be wrong.

 

SE Finescale also produce a kit, and as far as I can see the only real difference is the bunker - but don't know where they got the details from.

 

Jim Snowdon managed to "liberate" many of the old Met/LT drawings - which is how his Met Rolling Stock book came about. I wonder if he can help?

 

<edit> Have just phoned someone who should know (used to work with my father), and he has confirmed what I thought - they were identical except for bunkers, wheel arrangement and steam heating (F class wasn't used for passenger stock work - although he understood they were substituted for E class on occasions during WW2.

 

Forgot to mention I answered a similar question on another thread:

 

The F class, although very similar to the E, was in fact nearly  1ft longer (my dad who used to drive F class locos for LT, used to call them the "big engines" when comparing them to the E class - I won't say what he called the panniers when they arrived ). I think the difference might be because the F class had a larger coal bunker.

However the boilers and cylinders were the same as the later E class (the earlier E class cylinders were 0.5 in smaller than the later ones - definitely won't be noticeable in 2mm scale!).

Some basic dimensions:

Overall Length 33ft (over buffers)

Footplate width  8ft 5in

Driving wheels 5ft 6in (wheelbase 7ft 5in)

Bogie wheels 3ft 9.5 inch

Not them but I expect someone on here will clarify .....

 

I've a GS Models F-class and also the SEFinecast one, both in the roundtuit pile.

The GS body kit advert (which was in MRC at the time) said that Roxey Mouldings was to produce a chassis kit. So thought I'd wait until that was available, as at that time I was new to modelling. After a while I got round to asking Dave when the chassis would be available, and he said that was the first he had heard of it. So never got round to buying the body kit.

thanks for showing photos. The basic info*(drawing) was very limited, but the small number of photos helped.

As for selling stl files, only for what some might think a high price. Once they are out there, I have lost them, and people would share them, what ever they said. Having said that I am prepared to work with anyone who can 3D print models to sell on, but I think some find this is more difficult than they expected.

Would a license or product key to protect the stl file and limit the number of downloads/computers it’s saved on be possible?

 

I completely understand and support the need to protect one’s intellectual property, but I too am unimpressed with some of the quality /price issues on shapeways especially compared to using a  resin printer of my own.   I’m currently drawing up files for my own projects and I’m sure a (very) small minority of lunatics would find them of interest, but without a way to protect my IP it seems that shapeways is the only option...

I doubt if there is any completely secure system.Computers are basically very sophistic code braking machones!

The idea of something that allows only single use would be a good idea. There are now tools which protect pdf files so something similar might be done for stl files. Having said that someone who knows their way round files and computer systems could probably override any controls as they are probably quite crude mechanisms .

Until someone does bring in something which protects stl files then chances of stl files being made available is very slim. Andthis is only really for personal use. What happens when 3D printing becomes the main method od manufacture, and done at home, rather than large factories, it is not just a few individuals and their time that are at risk, but big companies.

Back in the 70s and early 80s IT companies did not appreciate that companies would only buy one copy of some software, then copy it to all of their computers, but when they found out, we saw many more controls including dongles for some hardware connections. Having said that, within the IT world we tended to share ideas and adapt, and as a result probably did a lot more that=n if we had limited ourselves to what we had been officially taught(traing courses were relatively rare, except when they were essential).

something different, and these were requested so have given it a try. The BR class 310 EMU introduced in 1960s when West Coast mainline electrified.

 

It should also be noted that Shapeways is still operating at the moment

had a request for some LMS non corridor coaches, but not specific on type, so sarted with period 1 and 2 lavatory stock. This is v-basically the same as the old Airfix/Dapol ones which are period 2. Just need to work through all the other LMS non corridor coaches, including the articulated ones. Long slow job,so will add them one at a time.

Started on some more District stock. Someone asked, so had a look. Thought I had drawings , but could only find one for E and B. I am not happy with the B on as it has an obvious error with respect to width, but shoud be able to do something.

Done the E stock. Luckily it had been designed to be suitable for conversion from motordriver to trailer and visa versa, so onlyone design which can be added to if required. The C and D stock is said to be similar design , but with clerestory roof, and there were some mods done to cab windows for different versions over the years. The B stock is different(wider and longer) but I should be able to do something.

Took the chance to add O and G1 versions to the F stock.

back up north, with the fist of the LYR electric stock for Southport line. Luckily I had a cpy of a couple of the drawings as well as another less detailed drawing so could work out the designs, but unlike other railcar/coach designs there did not seem to be much logic with respect to window positions so have done asbest as I could.

following a request for an LNER G59ex NER O) class 0-4-4T loco, and with some decent drawings have done 4 versions, from original to theone with an extended hopper bunker.

I think the question is often asked because you are listing your business products in the "Skills and and Knowledge" section. rather than "Small Suppliers, where sharing is not to be expected.

Skills are not resticted to those who make but also those who specialise in designin. Maany of those who want stl files just want to print models using their own printrs. There may be some sjkill in setting up a 3D printer, partly because we most machines are not yet totally plug and play, but there is a lot more skil involved in designing models. I struggled with CAD software (despite spending many years in IT) until the package I use was suggested, but t wasn't instant, I have built up my skills using it over past 5 years, and hopefully got better.

I am happy to offer advice to anyone wanting to do 3D design from my own experience.Forums such as this are good places for advice, but not everything on forums is correct or should be taken as gospel truth, so discussion is useful, so we can all learn.

I wonder where the idea that 'sharing' designs comes from. It has probably come from the IT world, where ideas are shared and so much software is free, but often only a sample just to get interest, otherwise there would be no IT development.
