Ernies 7mm Wagons - 21 ton MDV

Recommended Posts

Just found an HMRS drawing on line https://hmrs.org.uk/drawings/16-ton-all-steel-mineral-wagon-2-side-2-bottom-1-end-door-9ft-w-b-19ft-6ins-o-a.html

 

This shows that the clearance on the Chas. Roberts Minerals is not massive on the prototype, so will go with it.

 

I seem to be on a bit of a roll today.   Adjusted the alignment of some Cooper Craft pushers.  It will be fitted ar$e about face, so I might drill out the pin holes, just for fun, and add a wire safety loop....

Quite please with todays efforts.  Fitted couplings to several wagons.  Also sorted out some stuff in the workshop.  I also got some underframes ready to fit.

 

Here are some of the couplings, need some nice thin paint to weather them...:

I made sure I did a bit today. Straightened a few buffers and cut a body to shorten to the right length for a 9’ wheelbase version. 

 

Here they are, with the newest first.

The Cooper Craft Underframe has been screwed in place. It can now be unscrewed, slit into 2 and the spoked wheels replaced by 3 hole disc. There’s also a pair of brake blocks to come off.....  

Tonight it will get stand in buffers and drawgear. It can then run if required.....

Working on the principle that you can never have too many projects on the go. Guess what  it’s made from and guess what this will be. The clues are a spare set of 12’ wheelbase solebars and I have a picture showing one at Hayling Island.....

One of my minerals is using the original chassis shortened. The ends are located using the corner pips. It actually sits up inside the lower extension to the body. It has scrap styrene glued underneath, so that when sawn in half it sits evenly.   As usual everything is held together by screws

I drilled out the axleboxes to take Peco bearings. Enlarging the holes to let it sit at the right height....

Here is a stop gap headstock fitted.

The axle boxes will be filled when the bearings are set up at the right height and flat fronts added to the boxes.

My own view is is that this modelling style is the true spirit of O gauge.

The 'red' 'no top door' version has had some more body parts added.  To enable running I have fitted some couplings to the 'stop gap' headstocks..  I have used some Dapol links from their 3 link version, These are slipped into the Peco RCH hook,

The 'red' one has a Cooper Craft Underframe.  The 'green' one has a Big Train Underframe, bodged to enable its use.  To get the ride height correct it gets mounted inside an evergreen 'skirt'.  I therefore needed some cosmetic solebars to complete the illusion.  Luckily I had some spare evergreen channel that has been added, just need to wait for the cement to dry and to fettle the ends to join to the headstock.

 

This one needs the rest of the door and end detail added, plus some couplers, then a first coat of grey will take them to that next stage....

I want to get to the end of my Mineral production line, so am seeking to batch each job where possible, as I want to get them to the 'running stage' as quickly as possible

 

I cut a sheet of thick styrene to form the base to give the extra height to the Big Train / Lima body.  I have used my 'weapon of choice', the small circular saw blade in a dremel, to hack out the door and trim to allow assembly at the new shorter scale length.

 

Cutting the next 4 bases...

So 4 more doors to make...

Here are my 'too long in the workshop' specimens...

 

The one on the left has the Cooper Craft Chassis split into 2 and screwed to the body.  The 'stop gap' buffer beams are also screwed to the body.  I want to try making some of similar shape, but with sprung buffers.

 

The use of the Big Train / Lima underframe is too much of a work up and is not likely to be repeated.

 

So tomorrow Matthew I'll be making doors......

Slightly different subject tonight...  I'm always thinking about the numbering etc and how it can be quite random in font style.  I had been musing about the old 'John Bull Printing Outfit' and the hours of fun as a kid....

 

So a quick search on ebay got me a cheap Dormy set of 3 and 4 mm letters / numbers..

 

Being as patient as always I had to give it a try.  Here is the first attempt with some acrylic white.  The number was random.  I need to cut the holder down as it would not sit down evenly.  It has spurred me on to get more practice in.

 

This is the effect, then below the cruel close up.  Has anyone else tried such a technique?

I have been talking to a Rubber Stamp company today..

 

Most enlightening, they actually do white ink and 2 mm letters /numbers,  So I've placed an order for various items and included this beast in the order.

 

So am looking forward to seeing how the white ink compares to the acrylic paint...

I’ve been churning out the cut and shut doors. Here’s the latest recipient.

I’ve also extended the side stanchions downwards. 

 

This one has got a Slaters wooden underframe rejigged to look like steel.

Plus a couple of standby buffer beams. Frigged up to screw on...

Today I've been fitting couplings and buffers.  I can now shunt with them, setting the ride height, so the tops are all even.  The second wagon is a 'Lionheart' model, the rest are Big Train/Lima conversions.  It will be good to get to the stage when they get a coat of grey paint...

Hi Ernie, 

I’ve been following this thread with interest for ages. I thought I would share a pic of my Limang minerals, done some time ago. They are all corrected to 9’ WB and bodies shortened, some without top doors. Unfortunately I was unaware the bodies were not high enough or that the doors were too narrow so these errors were not corrected. All have scratch built chassis with added bits from Slaters, Parkside and sundry white metal bits. The wheels a mixture but all metal tyres. They were fun to do and when run together without a Lionheart nearby they pass muster.

I apologise  for the contrast between morning sunshine and shadow here in Cyprus but I think the pic gives some idea of the result. 

Glad I did it as I can now see I’ve forgotten the brake levers on one wagon, that will be corrected later.

I look forward to the next episode.

Bob
