Airfix Siphon H detailing. With added Conflat

Like many of us we often have numerous projects on the go.

 

From a personal point of view I have the BR Clan's and Dapol BR Manor Class to complete. See my previous blog postings. All being well these should soon be completed. 

 

I have had an old Airfix Siphon H in my 'to do box' for a while. A quick strip down and prototype research reveled that Airfix had fitted the wrong bogies which on a Siphon H should be 9ft American Style. 

 

The existing bogies where put to one side. Then I removed the buffers, vacuum tanks and gas tanks with a pair of Xuron track cutters. These areas were made good with a scalpel, sand paper and files.

 

I ordered the correct 9ft American bogies as a pair, 3D printed from Shapeway. I believe these are designed by Stafford Road Modelworks.

The bogie prints are a bit rough and the detail is ill defined however from normal viewing distance the correct impression is given.

 

Airfix Wonderland...

 

The bogies were cleaned up with a soak in white spirit and also a fibreglass brush. 

 

Then Romford brass axle bearings were fitted and masked off. A quick blast of Halfords grey primer and satin black finished the job.

 

Using the existing mounting pins the bogies are a direct replacement. Bachmann coach wheels fit nicely.

Buffers were replaced with Slater's GWR coach buffers. LMS Models provide the coupling hooks.

 

Airfix Wonderland...

 

That's play for today with more planned including replacing the gas tanks and vacuum cylinders with MJT components and scratch building a few underframe elements.

 

Another Airfix build has involved a 10ft RCH chassis in the stock of spares. Armed with plastic sheet a basic Conflat was built.  I have Cambridge Custom Tranfers to hand so as to finish in early BR colours 

 

Airfix Wonderland...

 

I made the fixing rings from fuse wire. Buffers and coupling hooks from LMS Models as previous.  Tie bar is also from Microstrip.

 

Airfix Wonderland...

 

Thanks for looking. More soon.

 

Cheers,

Thanks Robin,

 

I planning on painting the Siphon in BR crimson.

 

Is there a Siphon H on ANTB by the way?

 

I need to put an order with MJT for gas tanks, vacuum cylinders and 'V' hangers. 

 

With a bit of scratch building of the trussing (Not Liz!!) on the underframe it should lift this venerable old model nicely. I will look at the brake gear as well for a representation.

 

I think you've used these 3D printed bogies previously as well on some of your stock.

 

Out of interest does any have a diagram of the underframe or a Siphon H to hand? 

 

Cheers,

I don't think the GWR made many of the H diagram and would therefore be a rare beast to see. So unless Accurascale announce one it's a no Mark.🤣 As for the bogies, I've used them [Dean type] on Hornby clerestories and can highly recommend them.

I'm not sure how many H diagram Siphons were made? 🤔

 

Never say never with Accurascale though...😉

 

I thought you had used the Dean bogies on one of your projects. Like you say highly recommended.

 

Cheers,

Nice to see the old Airfix Siphon H getting a new lease of life.

According to Russell there were 20, introduced 1919 and numbered 1422-41 in GWR days (plus a prototype experiment that was a hybrid Siphon H and G).

Thanks Mikkel,

 

The old Airfix Siphon H is a lovely model and hopefully a few tweets to the underframe and bogie swap will lift it.

 

Thanks as well for the prototype information. Much appreciated.

Must have missed this…

 

Very nice work as usual.

 

How’s the 2mm workbench looking? 😉
