While perusing Hatton's this wagon caught my eye (I'm going to have get drops for that):



Really quite good to my thinking, above the sole bars anyway.  I don't like that the brakes are mile away from the wheels and the brake gear seems a bit wimbly.

Side doors really do open and the fit is very good - you can't easily see the join can you?

Buffers and couplings are sprung.

I've ordered some Bill Bedford kits from Eileen's Emporium - sprung W irons and brake gear.  When fitted this wagon will look super.

The parts I need to upgrade the Dapol wagon arrived.  I spent some time today taking the thing apart.  Flippin' 'eck, the glue Dapol used to secure the W iron/brakegear moulding is strong!  I ended up using a cutting wheel to remove material around the moulding until I had enough leverage to wrench it off.  Not for the faint hearted this.



The underside of the wagon body looks a proper mess but it'll tidy up as we proceed.  Note the solebar overlays.



The two Bill Bedford kits required for the upgrade.  At top are the sprung W irons - I've discussed these before.

At bottom is the brake gear fret.

The model W irons look quite thick - I might just chop them up for the springs and axle boxes.

Now that I have the new layout benchwork done and waiting for points, I spent some time today on the Dapol PO wagon.



I assembled the Bill Bedford W irons and blackened them.

The white strips on the floor of the wagon are 0.060" plastic strip which should bring the W irons to the correct height (it did on my previous two wagons).

In looking through a Slater's kit for a standard BR van, I found that there was a sprue for manual brakes and one for clasp brakes (no yokes etc. but I can make these) so I robbed the W irons and chopped them up for the springs and axle boxes.

I discovered why the wheels have so much side to side slop, the axles are 2mm shorter than Slater's wheels.  Must think about that, the slop really is unacceptable to me.

State of play with my Dapol wagon:



Fortunately I had my Parkside wagon to compare to.  You can see I packed the rear of the solebars to push the W irons inwards.  The axles engage the bearings now.  I still have to install the brake lever, but I think I'll paint first.

I'm about to bring my brake van to completion:



These shots illustrate the completed interior, although my friend complained that there was no bucket or brush.  :roll:

It's difficult to see, but there is a stove.

I can finally stick the roof on, after which no-one will be able to see all this - tccch!

I finished my Dapol PO wagon:



Main improvements are that the brakes are properly close to the wheels, there is no ridiculous side play and wheels are sprung.  I also replaced the ring retainer for the coupling spring with a split pin.

Eventually this wagon will be depicted in "end of life" condition as most were in 1962.

I don't think I'll buy another RTR PO wagon from Dapol.  Lionheart PO wagons look to be a lot better.  Anyway, I've enough wagon kits to keep me busy for some time.

That looks really nice, John.   :thumbs

Are the chains the right scale?  I'm always over scale with chains.   :roll:

Thanks Max.  Y'know, I don't know if the links are right, they look right to my eye.  I know in 4mm, they always seemed overscale.  The compromise required to make using 3 link a practical proposition (although it never was for me).

The last thing I did on my brake was to add safety loops under the brake yokes.  These are not provided in the kit, nor is there mention of them.  I made them from 0.032" brass wire, chemically blackened:



I think I can call construction complete.  I will be weathering this at some point.

My next kit is a Slaters BR Standard Van.  My friend is building the same kit so I want to be able to see what he's complaining about.  Mind you my plan is to build this in the slightly less common 8 clasp brake version.

The kit comes provisioned for the 4 brake version but does include a fret with clasp brakes and axle guards.

Being me, I opted to use Slaters sprung W irons and made these up:



All really self explanatory.  Whenever you're dealing with small springs things do get fiddly.  To Slaters credit there are a load of spare springs in the packet. :Happy

The half etches were initially a mystery to me and I only just twigged that the W irons are cranked slightly outwards using the half etches as bend guides.  :roll:

So, on to the van.  The instructions don't have much text and there isn't a step by step guide.  I suppose there's an assumption that the builder has some experience and some familiarity with the prototype.

I found a lot of great photos of this van here:  Paul Bartlett's Photographs | Britain's Railway Wagons & other rolling stock   :doublethumb

Therefore I just put the van together, floor, solebars, sides and ends - not rocket science:



I blackened the W irons.

Underneath:



The floor ribs are stuck on and embellished with plastic strip to make them channel.  The brass wire is the vacuum pipe.  I made holding brackets from wire and secured everything with CA.

I've been steadily working on the van:



Wheels and clasp brakes installed.  You can see the coil springs above the axle boxes.  Very smooth running.

Fast forward a few days and the wagon is nearly finished:



I have the axleboxes and springs on.  Brake gear is also installed - what a faff!  There are lost wax door catches and brackets on the solebar.  Still have the brake levers to do.



Here's a view of the underframe showing brake gear.  It took a bit of brain power to figure out but I think it makes mechanical sense.  The white bits are handmade with plastic strip, copied from a Parkside kit with a similar arrangement.  There's a pipe connected the vacuum cylinder to the vac pipe.

Note also the safety loops around the pull rods and yokes.

I am waiting for Oleo buffers so that will take a week or so.

After I took the pictures in the previous post I was disgusted to discover, when I scrutinized photos of the clasp brake version of the van, that I had it all wrong.

I spent the last while figuring out how to represent the prototype and here's what I came up with:





You can see that each side is quite different.  The side opposite the vac cylinder at top, has an additional hanger for the brake lever to pivot on.  Brakes are actuated by the brackets connected to the lever and brake rod.

On the vac cylinder side, The V hanger has a hole midway up to act as brake lever pivot.  The brake lever is extended and connected to brackets.

This arrangement means that the direction of pull for manual braking is correct.

You'll also notice that the body has been primed and the underframe painted black.

My Oleo buffers arrived yesterday so I spent some time detailing the van ends:



I got the buffers from Invertrain, they are made by Haywood Models.  

The vacuum pipe is lost wax and is inserted into a hole under the buffer beam.  Note to wagon kit builders and bashers, vac pipes go UNDER the buffer beam.

The hose is a fine wound metal, don't know what it is, I wanted to blacken it but my solutions won't touch it.

The connector is also lost wax.

There's a bracket with a connector on the buffer beam just peeping out behind the LH buffer.  The vacuum hose would get connected to this to maintain vacuum if the van was at the end of a train.

Lastly, there is a lamp bracket, again for use if the van is the last vehicle in a train.

Still to fit is the screw link coupling after paint.

I think we're done and painting is next.

With respect to the vacuum pipe, have you thought about using a black permanent marker?
Looking good so far!

LOL Jeff, exactly what I have done.  Paint is too thick. 

I think the hose connector might join to an adjacent wagon hose and stay by spring force - we'll see.  There are also tiny magnets that could be glued to the connector.

I really like that you get so much more detail in this scale Max.

India ink works well.

I have a marker but no India ink.  I need to get some so I can try weathering techniques with it.
