I have this which was my Grandfather's workshop lamp, which he bought between the wars apparently, and with a modern LED bulb fitted is very good - I restored it in 2017 - It is a Herbert Terry model Model 1227 and has all its original features including the adjustable spring holders.

I have a Rolson Magnifying Visor, which I wear for high detail stuff, it has a little light but I never use it.

.... from what I know, the american air system had a set up so that as the coupling pins were retracted the brakes were applied - it could be something like that ? - any how, I have been doing a bit more as and when work and family allow !

any one any ideas on what the second vac pipe was for ?

https://www.youtube.com/watch?v=XDRzc16CWzc - looks a bit duff to me.

... now for the top bit !

.... basic geometry done

.... fixed it !

.... now with 30" wheels, altered underframe with repositioned pivot and adjusted wheel holder casting.

.... conversely, the adapter bogie frame looks a lot better with 30 inch wheels !

.... did nobody spot the major error in my work ? - today I started to assemble the adapter bogie and then it hit me !  - those wheels look small, I thought - a bit of checking and I have done all the work on the underframe etc upon the Roadrailer on 2ft rail wheels like the US version ! , the whole way through I have for some unknown to me reason worked with the wrong size wheels ! - when I look at there are proportional clues it is obvious - how did I not spot it ! - 

.... this will require some major rework of the underframe components, as they will be 3 inches too far rearwards and the big casting is 3 inches too short, all the brakes have been done to fit around a diameter that is 6 inches too small - what a fool !

OK - its been detective time, looking at the bottom photo below -:

.... it shows some extra bits that are not on the prototypes (circled) - I know what some of them are as they are in the 'Eagle' illustration as below,

... but what is the indicator board part, it seems to fit around and to the right of the vacuum brake handle (that is on the prototypes) and the needle points down and slightly rearward when in the rail configuration - there are a couple of other parts that I am not sure of as shown above (not on the prototypes) - any help appreciated ?

I was intrigued to the date/timeline of this photo so started looking - the cab of the lorry tells a story - it is an Leyland with an LAD cab, but not the late 50s version, it has the later rounded arches, after a while I had deduced it was a Leyland Beaver, then some luck - whilst looking for Leyland Beaver images I found a dated photo of a Leyland Beaver with a Roadrailer Trailer ! - incorrectly labeled as Container semi-trailer “RoadRailer” - looks like its outside the factory, like some of the other pictures of it and the one above, that I have found (from the same set ?) .... its date 24-09-1962

it is available here http://www.britishcommercialvehiclemuseum.com/image-archives/product/leyland-beaver-power-plusl069499a/

All these items are only on the production versions from what I have found - any proof otherwise greatly received.

.... definitely Brush ponies - I have a picture where you can see the Brush logo 

.... it is not just a compressor, it's a complete little 3 wheeled truck (as below) and proportionally I would say that sheeted down it about the right size for one of the black lumps, perhaps there were two of them ?

... any recommendations on wheels and bearings?, I see you can get 14.1mm metal disk wheels, and brass top hat bearings, I have started the model underframe and bogie so have to plan for what to fit, and how to make it so as to be able to be assembled relatively easily. 

..... of interest -: I bought a magazine with a free 'grounded wagon' kit attached and have taken a close look at the detail and rivets - the angle iron frame is 0.5mm thick (38mm true scale) as is the rivet diameter, best measurement I could get on the rivet head thickness was 0.46mm) so was probably the same. It gives a convincing visual representation of a wagon so some scale fudging may have to be done (like the original kit)

Andy

... OK, this has come out better than I thought ?

.... but in my rush I did not wash it properly !  - (stupid boy !)

1/2" rivets at 2" spacing in 1/76 scale - straight off the printer -:

I have got it in position for a trial 3D Print, to see how the rivets look before I do any more detailing -:

Hi Andy,

 

I've been following your thread with interest and may I say, excellent work so far !

 

Your comments upon the size of rivet heads is an interesting one for there are various sections of materials that do not necessarily scale for instance, a steam locomotive's buffer beam at 1"thick would scale to .013" or .33mm in 4mm scale and the only rivets that might stand out in true scale would be boiler and main frame rivets at approximately 1.25" head diameter. The Roadrailers were not built quite so solidly built as any steam locomotive.

 

I would suggest that leaving the small rivet detail off is as good as offering fair representation of rivets and comes down to a matter of choice dictated by what anyone ought to be able to see over what anyone might think that they should be able see.

A tricky call. one that I would answer by saying, if it looks right it is right.

 

Gibbo.

 

.... yes " if it looks right, it is right" was often used at work before it went all CAD and CNC - but so was "good enough for spares " !      

.... the simplified kit assembly shown above does not have all the detail items hung onto the parts yet - far easier and simpler to get the fit and build right with simplified components and then add the correct amount of detail too it - there are 144 component parts to the detailed CAD model !

.... looking for ideas as to what other modelers do or what people actually want from a kit ? - the scalecraft kit version has 16 rivet heads of around a scale .75 inch diameter spaced approx 4 inches apart (this gives the idea of it looking something like real but is not) -  in reality there are 38 .375 inch rivets spaced 2 inches apart - will this just be unrealistic at a scale size - in my test they are barely visible at 7mm scale to the naked eye, but look good with a magnifying glass ! then at 4mm they are there but barely visible even with the magnifying glass.

Do people just want a reproduction of the scalecraft kit, with more correct details in certain areas - for exmple the roofline, wheels tucking under etc. ?

.... here is the latest -:

..... this is just the beginning of the kit,

Will the body be hollow orvserator seperate sections to join ?
If it one solid piece it will add to the cost.
Seperate doors at the back at least would be good as it would provide an easy solution to have the rear doors open

...... at present I have not gone for openable doors, but it is hollow - I may look at doing it but it will involve more scale fudging to make it possible.

I am doing the pre production, and production variations now.

... the model draws closer - a few bits to tidy up and then it is detailing the kit parts  

.... getting the details right is taking time -:

..... and I now have this -:

....  a bit more accurate ?

EDIT :- .... no, no no    ! - wrong wheels for that sign !

You'll have to be careful with the lettering on the board in that format. As far as I can tell that format was only used on the two prototypes whilst running with the early style of roadwheel and at the Marylebone exhibition.  (and travel to from?)  By the time of the commercial Motor show a few months later, the simpler styled overall blue with just the capitalised "roadrailer" script was fitted.

 

I think the BRS was dropped due to British Road Services developing resistance to the overall Roadrailer project.

 

P

.... I agree, it would be very time / date specific like that - I do have the other wheel type and roof line planned, so my kit will have alternate parts so you can do what you like, prototype, production, road wheels up, road wheels down, landing legs road wheel, landing legs rail wheel, landing legs retracted, I will also make a US prototype 1, US prototype 2 and US production.
