BR built (Shildon, 1949 - to LNER design, Diag 1/031, Lot 2032) 13T Shock Open Merchandise wagon B720128 at Water Orton - c.1959. 

Note the off-set positioning of the end "shock stripes" - the original style for these.

 

An excellent inspirational picture.  It gives some great detail of the wagon.  It has spoked wheels...  I thought that 3 hole disc were standard, but I'm sure that in the dark days of austerity any wheel sets available would have been used..

 

A big thanks to John Turner, Merry Christmas

FRUIT Van Continued

 

My theme this year is to finish things off.....

 

So combined with an office/work room sort out, I could find all the parts I needed. plus each part finished model sits in a project box with its own work sheet.  The worksheet is a record of what's required.

 

In this case I dug out the LNER Fruit Van...  I'd used the Parkside buffers on my 10'WB Mineral..  This one therefore got a very nice set of 'Welcome Models' buffers.  I think the are really smart.  The bases are cast and need just the slightest bit of cleaning up around the stub that will fit in the headstock.  The Parkside headstocks has the holes opened up a tad and the bases superglued in place.

A Stenson Models RCH hook and a Dapol Screw coupling were added. 

 

I was thinking I might give the body its first coat of paint this afternoon...  However the ever cruel pictures shows that the corner joints need a touch of filling...

The Shock open has been making progress.  I had something lines up for the dimples, but forgot what it was....  So a search of the odds and ends box offered a piece of round sprue, a few slices were cut off and cemented in place.  A run of cement was placed round each dimple to smooth it off.  A piece of wood is ready to be used as the weight for the wagon, plus it will keep it all square.  I have a  cunning plan to square them all to the same thickness....

Ernie,

 

I hope you enjoyed Christmas and will have a prosperous New Year.

 

Your shock wagon is of renewed interest to me. For Christmas I received a Slater's Wagon Kit, 7064 BR Standard/Fruit Van. It has parts to allow some variety in construction.

 

One of the enclosed sprues is X7060C which is supplied for the Vac cylinder and some brake parts. The rest will be unused including the shock underframe sole bars, shock springs, headstocks, axles guards, axle boxes/springs and 8 brake shoe rigs plus other bits. 

 

So following your build I should, along with a bit of scratchbuilding, end up with two wagons almost for the price of one. It really is Christmas!

While tidying up ( a continuous process) I came across the missing brake blocks..

 

post-2484-0-08514900-1546275860_thumb.jpg

 

The buffer shanks have now been fitted.  The chassis and body are screwed to a wooden block to ensure squareness....  One end stanchion has been shaped, need to do the other.  I have a list of things to do tonight, will see how that goes....

 

post-2484-0-22581700-1546275825_thumb.jpg

 

I need to think about a load, probably a crate of equipment destined for the Navy..........

BRAKE SET UP

 

Once I had located the errant set of brake blocks I could proceed with the brake set up.  I'm in a slight quandary as the brakework needs to be reasonably robust, but at the same time allow the wheelsets to be removed if required without destroying the rigging...

 

I started to construct the Vee hangers using some Parkside parts that I will not use for their designed purpose... 

 

The Slaters Chassis comes with RCH style 4 block pusher brakes, this version has the LNER style 8 block clasp arrangement.

 

The cranks and connecting rod were from my 'general brakework' box...

 

post-2484-0-80896800-1546340064_thumb.jpg

 

Once these have set I will add the other leg of each Vee Hanger.

 

In the pictures below I have placed some Parkside Brake Beams between the Blocks.  I think they will be trimmed as in the 'red parts' in the diagram below.  The green parts are the Safety Loops, these 'catch' any brakework that becomes disengaged.  I think these can be made to fit last.  The two loops for each axle made from one piece of bent wire, hopefully they can be sandwiched between 2 pieces of styrene and then secured using the screws that hold the chassis through the body to the wooden block.

 

 post-2484-0-04936900-1546341757_thumb.jpg

 

Using my trusty Tatlow book I see that the brake cylinder is offset by 6".  Slid between the chassis and the underside of the body is a piece of backing paper (non stick) from paper labels, this will stop any stray glue sticking it all together...  Once I have worked out the correct 'jaunty angle' for the cylinder..

ASSUME makes an ASS out of U and ME, how true....

 

I fell for this one, cemented the brake cylinder in place, started fixing the V hangers and I had an Oh Sh*t moment, something wasn't right.....

 

I checked various pictures, still confusion, then the penny dropped....

 

The views in the Tatlow book are from the side and from above, in my stupid head I thought I was looking from below, my excuse is that's the way I normally see wagons.....

 

Here with re-located vacuum cylinder.....  One of the Vee's has lost a leg, I've got it and will cement in place later...

 

post-2484-0-56205900-1546371900_thumb.jpg

 

A bonus was the realisation that the drawing in the book was 7mm......  I think I get 'duffer of the week' award....

I'm adding all the bits of the brakework.  Some Parkside beams were added and after positioning at the correct angle, cemented in place.  As they looked a bit on the flimsy side I've added some additional material to the beams, hopefully they will 'reduce in size' when it's all painted in gungy brown... 

 

post-2484-0-12822300-1546543326_thumb.jpg

 

The main brake shaft was fabricated using a piece of brass wire, Parkside parts and a piece of evergreen tube.

 

post-2484-0-19090700-1546543317_thumb.jpg

 

The brake shaft will be sprung into place last, between the vee hangers.  I'll bend some brass levers, with some brass strip formed into the guides, soldering the two pieces with a pin through the two pieces to allow mounting to the solebar.

post-2484-0-90829300-1546543330_thumb.jpg

 

When the cement has all set up I need to do some fettling with files and fine sand paper, just a little easing to shape the brake blocks etc.....

With the work on the Shock Open progressing I have started to catch up with the brake work on the LNER Fruit Van, Both are Clasp brakes LNER style.  The van has rigid axles, home made solebars with Slaters (I think) guard irons.  After the success of mounting the brake hangers directly to the floor on the open, I have started adding the outer blocks on the van...

 

post-2484-0-85416000-1546646695_thumb.jpg

 

You will note the green arrows to ensure the brake assembly is fitted the correct way round...

 

post-2484-0-20664200-1546646713_thumb.jpg

 

I used a green paint pen, so now I know which is my left hand...

 

post-2484-0-75707800-1546646726_thumb.jpg

 

The axles are kept from having sideways slop by some thick spacers that are slipped over the brass bearings.  These will be cemented in place when the axle boxes have been made...

 

post-2484-0-95873500-1546646751_thumb.jpg

 

There is just an axle box to be fabbed up and cemented to each axle guard.

 

post-2484-0-90979000-1546646739_thumb.jpg

 

This is the axle box I'm going to make...

THINKING ABOUT THE LOAD

 

As the SHOCK OPEN nears completion I need to think more about the load.  Looking through books for inspiration I turned to one of the Larkin 'Working Wagons' books.  One picture shows 218741452260 (SNCF Railway Owned Steel Low Sided Open) passing Nunhead in 1974.  It is loaded with 4 large crated items.

 

post-2484-0-83434200-1546676580_thumb.jpg

 

I think the wood is used as a 'one journey' protection rather than a crate as the construction doesn't seem durable in the long term for use.  There looks to be one diagonal per end.  Might try some coffee stirrers...

When I worked in engineering stores, non-returnable wooden cases were treasure trove. Any store-keeper worth their salt would keep a claw-hammer and a nail-bar under the counter, and could reduce a large crate to its component parts in half-an-hour of someone else's time. At various times, I used timber from such things to make a foldable artist's easel, a garden railway, path edging and a compost bin.

Cases usually had a lot of stencilled lettering indicating consignor and consignee, which way up it should be, where slings/ forks should and shouldn't be placed etc; sometimes, these were observed..

The Grey Funnel were great users of cases, 'conveyance of materials for the use of', the Army and RAF less so.

We had a Chargeman at Dover who had the epithet of 'Jewson', he worked to the same principles, he would scour wagons for any loose dunnage etc.  Some was still nailed to the wagon decks, that was soon removed....

A grand tradition of cadging; if it could be carried on a bicycle crossbar, it probably would be. We used to have a hen cree when we lived in the North-East, made largely of planks from NCB internal-users from the adjacent colliery. Bizarrely, it also incorporated a sheet of Perspex, painted with the RAF arms and motto; fortunately, our chickens didn't have any Latin.

The 'door bangers' on the shock open stick out quite a distance from the solebar, so I thought they need to be quite robust.  Looking through the material available, I was planning to use some Ambis levers and the spare fret had a suitable section.  This was tidied up with a file, then the strip was bent around the shank of a small drill.

 

post-2484-0-93208400-1546705315_thumb.jpg

 

The in true Blue Peter fashion I made use of a toilet roll tube (We keep ours for use as compostable seed pots) that was handy in the workshop.  Flattened and folded the 4 thicknesses of card was just right to stop the bend being crushed in the vice.

 

post-2484-0-22081400-1546705320_thumb.jpg

 

The piece ready in the vice.

 

post-2484-0-52258100-1546705328_thumb.jpg

 

A razor saw made short work of cutting the strip into 2 pieces

 

post-2484-0-35540100-1546705293_thumb.jpg

 

The pre-bending allowed the end to be tweaked to give the correct shape to the end

 

post-2484-0-90034100-1546705296_thumb.jpg

 

The other end of each piece was bent to fit in place on the underframe and the the end is trapped by cementing pieces of scrap styrene around the end.

 

post-2484-0-05098500-1546705282_thumb.jpg

 

Here is the under frame upside down.  The brakeshaft is made of evergreen tube.  I'm thinking of soldering a fine pin into the brake lever, the pin can slide into the hollow shaft.  The assembly being retained by the paint, everything being able removable at overhaul if required.

Ernie,

 

Great work. Thanks for posting some very useful photos.

 

I like the tip for differentiating left and right hands. Do you have any tips for up and down? I could do with one.

 

Ian Major.

Ian

 

I have no trouble with up and down, all my missing stuff ends up on the floor......

Did a bit of soldering tonight, got the short shafts on a few levers and bent up and soldered as brake slide.  I really like the improvement of the etched levers.  Don't want to sound unappreciative but the levers can be cut from sheet and bent up.

Most plastic levers are pretty flat.  Real levers are anything but...

I've been busy with the safety loops.  I was planning to solder these to a piece of scrap brass, but ended up using a piece of fibre glass PC board.  The loops are made from handy paper clips.  They might be a little on the big side but quite bullet proof...

 

They are straightened and soldered to the board.  Using some wooden clothes pegs to hold the parts and a big 'f*ck *ff' 100 watt iron I felt like a proper O gauge modeller...

 

 

Here when bent into shape,

The wooden block has been trimmed down as the 'crate' will need to sit over the top...

A couple of detail shots, first one from the end...

 

post-2484-0-00148400-1546994302_thumb.jpg

 

The last shows the loop hiding away, The cross shaft and levers are to be added.  I do like the look of the door bangers....

I'm on a mission to finish the Shock Open.  The definition of finished is to get it painted, some numbers added etc.  It will need to have couplings fitted for shunting.

 

It also needs a load..

 

Whatever the load is, has now been crated up.  It is built around a block of wood.  The glue needs to dry overnight, then the body will get a light sand and finishing off...

The packing gang must have been on 'Job and Knock' this morning.  The crate looks to be ready for loading..  I can't see any nail heads...  Not sure what to do about that ones as I couldn't see them in my reference picture... plus this is a looking too close, I'll be at least 2 feet away....

I loaded the crate into the wagon.  I'm not sure if it's too big?  Not high enough?  It might look different when the wagon has been painted and weathered...

 

post-2484-0-73810300-1547417255_thumb.jpg

 

I fixed the body to a stick to hold it whilst painting...

post-2484-0-61645200-1547417234_thumb.jpg

 

The colour is not solid, but that's not a bad thing.  It gives some variance for the weathering.  I will apply the numbers next, then start with the weathering.

 

As I have numerous tins of paint I recorded the colour used on it's 'record card', the sheet is a bit of fun, but at the same time a record of the work history etc.

  • 2 weeks later...

We went to Canterbury last weekend, but had to come home early because of Flu.  It was the 'Final Fling' of Tonbridge West Yard and I had also been to its first outing to Blackburn over 30 years ago..

 

The Flu has been slow to go and am not completely over it.  The only modelling of any kind has been shuffling of storage boxes...

 

Tonight I thought I'd add the etched brass covers for the shock absorbing springs.  I scored the etched fold line to make the bend easier, look how it turned out....post-2484-0-22496800-1548537799_thumb.jpg

 

post-2484-0-31577700-1548537713_thumb.jpg

 

Pretty crap effort if you ask me......

 

So I've just knocked up a couple of styrene versions....

post-2484-0-99723100-1548537721_thumb.jpg

 

Hopefully I can add them tomorrow, that should allow a base coat on the underframe.....
