Been out this afternoon to Lynn (Kings) with Linda, discovered a not bad model shop and a Caribbean Restaurant, double bonus.

 

Couldn't wait to try the under frame.  I had to pull out some of the bits of card I'd stuck inside the body.  Near enough for a test run.  Posed it on the Brighton Works headshunt, showing off the LED lighting...

In handling I've slightly bowed the tops of the sides, but that will soon straighten out.  Here is a side on view...

When we were out I purchased a pack of the Peco Fine Track Pins.  I had a crisis of confidence earlier and Steve Farmer gave me the kick I needed...  Thanks Steve.

 

I drilled a pilot hole first, then inserted the shortened pin......

Here's the cruel close up...

They might seem a bit over scale, but I think the contrast in colour doesn't help.  Let's see how they look when grey all over..

I glued the roof sections. The PVA allowed movement fit setting up. It was pegged up for an hour, the swapped to the slightly tighter radius of the inside of the Parkside roof. 

Let’s see how stiff it is tomorrow.

I gave the interior a quick run down and a rough coat of acrylic to show the bumps and dips before filling for the last time.

in the background is a BTC red / green card.

Some Manila card was marked up for the drawbar face plates.

The slot made with 2 drilled holes joined with a knife.

Then using a Peco coupling modded with 2 non magnetic copper links, it is glued in place.

I’m quite pleased with the effect. 

 

I like the fact that I’m making the parts myself.

I split the underframe down the middle and with a strap fixed to each half I was able to secure the underframe with 2 screws.

I then sliced up a business card for hinges and other iron work.

That’s it for tonight.  You might have notices the bolt heads are sometimes in random positions, that is because I cannot see what I'm doing..  Need better light and the old magnifier.....

Rivets / Bolts have been driving me up the wall. Scale, over scale, just a blob,  what is the solution.

 

As the construction medium is card I don't think I can emboss them from the rear, might just try it..

 

Ones made from card seemed too random and have a tendency to delaminate,,  So brainwave time.  I found some 40 thou square evergreen  Drilled a hole and inserted a small piece...

 

 IMG_0317.JPG.dcef09acd75893e2161dbe45d9ef6521.JPG  IMG_0318.JPG.cc50d7f4900bfc97ac37f6d68685789a.JPG   IMG_0319.JPG.37dd813f0f9e221254cc5593610b4b57.JPG

 

 

 

Need to see how they look when painted..

 

I thought long and hard about some form of standardisation.  Maybe push the long strip into the hole and cut off with a 'fence'....

So far so good,

 

Then some printed cosmetic solebars...

Until the PVA dries there is a bit of grease proof  paper stopping the under frame getting glued in.

 

Final thing is this session is to fix a bit of delamination in the headstock area, PVA larruped on and the area braced to dry, after I will brace the area, the draw bars will be solid, no springing there...

The end has got the thumbs up regarding bolt detail.  Quite good enough,

 

IMG_0339.jpg.a2addb268a89a037a85c23c2c3280393.jpg

 

The strapping however is getting a negative effect, I use a sharp bradall to make the hole and the raised edge thrown up should do, especially when weathered as the edge will catch the weathering..

  • 2 weeks later...

Home after a week and a half away....

 

At the end of last week I visited Grangemouth refinery, so was able to fit in visits to Boness and Locomotion.  

 

So lots of thinking, not too much actual modelling..

 

A project that's been in my head for some time is a Loriot Y.  I have previously bashed one in OO.

 

The base is a Darstaed Well Wagon, using the ends from my previous cut and shut.  Here is my butchery...

Watching closely the loriot conversion Ernie. 

Thanks steve. 

 

 

Steve

 

Like a lot of projects, I would do it another way if starting again...  I have another body to do and have an idea of the method.... 

 

One thing I want to try, is to mount one axle with inside bearings as a 'cannon tube', with the tube soldered to another tube at 90 degrees to form a pivot.  Giving some compensation.

 

More later today...

Just had a thought regarding roof construction.  A simple arc is quite easy from card.  However what was I going to for some SECR vans I was planning...  I could try and get some Parkside or Slaters mouldings.    Then I thought would it be so difficult, maybe a wooden moulding...  anyway reading old modelling books, they always made the roof from wood strips glued, filled and sanded, then covered with tissue.  Thinking some more, always a danger of over-thinking, trust me.

 

So tonight I thought what the heck, grabbing a handful of coffee stirrers, sorted out and discarded the ones that were like bananas..

 

Here's the model

 

1551728219_RoofDSCF5407.JPG.e7a65da4c04c0747c6fbec04c1074070.JPG

 

A number were roughly trimmed to length and a small blob of PVA put in a bottle top.  The first full width stirrer was placed along the centre line, the stirrers were added one at a time.  I kept to full width stirrers as far as I could.  Some had a slight touch of the B&Qs (the slight bends and twists of their 'boat building wood).  As I got to the point where there roof curve tightened up i split some along the length and finished to the edge of the roof.

 

The glue left in the bottle top was spread along any gaps in the joins and across the couple of stirrers that were a bit low in the middle.  I might wrap a couple of rubber bands around to keep in shape overnight.  Then thinking about another layer glued inside to form a ply effect.

I got back from my trip on Wednesday.  When I took the elastic bands from the roof it promptly pulled in at the bottom....  The action of the glue.  It almost went in the bin. but was put on the shelf, just in case.

 

The curve and the fact that the length was just a little shy of the required length looked like the 'death knell'.  Then a brainwave...  the first SECR vans with that roof were 9'6" wheelbase with a 17' length over headstocks, so a glimmer of hope appeared.  If I could only beat the roof into shape and make it stable it had a chance for a life extension.  Somewhere I had some thin ply, miracle of miracles, I found it and cut out a rectangle..

 

The rood was then cemented to the ply and left under a clamp.

Then scraps of wood were glued inside.  This should make a stable base....

This is my next victim from the OPC Illustrated History of Southern Wagons ; Volume 3 SECR.

 

It is a 10 ton Covered Goods wagon, SR diagram 1426.

Printed onto A4 label stock, stuck on card and shellac painted over...

Santa Special on the Epping and Ongar yesterday.  Interesting, but no present for me from Santa, must have been a naughty boy.

 

Anyway, my plan over Christmas is to not start too many models and get some finished off.

 

So door bar production line is underway, plus some hard core modelling.   Here is the hard core.....

 

A block of well seasoned timber that will form the core of the SECR van.

 

 

 

DSCF5417.JPG.e62e8121a5dd33a5a78252e372a94e2e.JPG

 

The shellac'd board has the planks marked with a fine rollerball pen.  These will now get cut out and assembled around the core, any width variation will be packed out with layers of card.

I've started assembling the card sides around the wood core.  In the spirit of re-cycling and 'waste not want not' I plan an attempt to create the T section and angle irons from thin card.

 

The first side is on....

A dry run with the end...

Then with the door...

 

DSCF5422.JPG.27e49a271328aeea6d917ac2259799f1.JPG

 

It will be interesting to see how this looks up against a Parkside rendition.  I'm thinking that I will finish this one as a fitted van...

The Loriot Y has also had some attention, a piece of MDF was cut to give the two ends something of substance to support the ends.   I can start to fabricate the girders between the ends, might need to set the angle of the end platforms as these seem to have been built with a slight positive camber.

The Loriot Y is getting the framing built up with odds and ends of plasticard, the underneath now has the bottom web done...

I've also cut out a rectangle to form the floor.  It has a couple of strips to form the inner part of the web, here upside down,...

When in position I will do some theatrical infilling, here are some rough shapes...

In the process I have discpvered a useful knibbling tool....  Heavy duty nail clippers....
