Airfix (now Hornby) B-Set upgrade

The last in this glut of blog entries for my historic projects, but one i hope to continue working on soon!

 

This has been a long running 'improvement' saga. Take one pair of Airfix B-Set coaches. Attempt to turn into a representation of the real thing. The body is correctly dimensioned but so many details are wrong. So far I've:

 

- blocked off the incorrect extra guard's window on the left hand side
- carved off the end detail and replaced the emergency brake gear on the outer ends only
- carved off the old grab rails and door handles, dug out the pockets and put in wire replacements
- re-done the under frame, relocating the battery boxes and correcting the brake cylinder pull rods and V-hangers for a hand braked vehicle, replacing the headstocks with straight ones, carving the buffers at inner end to be a representation of short buffers, replacing the outer end ones with long square shank buffer castings

 

Still to do:

 

detail the bogies
spring the outer end buffers (i.e. replace them)
add the guards steps to the under frame
paint the under frame
flush glaze
add number / guard / luggage / max weight decals, numbered for a Bristol area set
make a 'fixed' close coupling and join the pair to make a B-Set

 

Many thanks to Tim Venton of Clutton fame for the information required to do this detailing exercise (not the first to be shown on RMWeb)

 

more photos to follow as I complete this - can't wait to see them run in service!

 

(and then I want to do another conversion to as built condition in 1930 ... all those grab handle pockets :-( )

 

PS - an interesting feature of the door handle pockets is they run into the body side from the door - I didn't realise this until seeing a shot in the famous branchline trip shot by John Betjeman where he is seen stepping out of a B-set coach - the door handle pocket is clearly seen to run off the door edge.

Just wait now for Hornby to issue an upgraded model for £50 a piece!!

 

I wrote a little article to tell all I knew about the B-Sets and upgrading the model with much reference to Tim Venton:

 

(converted it to a .pdf so the system would accept it!)

Looking good.

 

Thanks for the generous comments.

 

It would be a ****** if Hornby did redo these coaches. They are about 40 year old mouldings, good in their day, but a bit lacking now.

I'm amazed that no one pulled me up on my statement about the number of truss rods - its a bit of an obscure topic though!  When I looked at the MRJ article on the A28 & A30 auto-trailers, I was gob smacked to see only two (outer) truss rods in the under frame details, because I had assumed (assumptions are bad) that all GWR coach under frames had four trusses ... not so it seems.  A hurried search through every photograph in my Russell GWR coaches volume two showed .... two truss rods on every 57' and 61' Collett coach (as far as could be told allowing for the Swindon habit of blanking out backgrounds in official photos which can loose vital details).  However FOUR truss rods are a feature of the 70' 1922 stock (understandably its longer and heavier) and the articulated 1925 stock.  OK it will be out with the knife when I can bear it :-( .....  (photographic evidence suggests that all 70' stock had four truss rods, 57' and shorter had two in general).  Under frame detail - a nightmare!

this blog entry just might be incorrectly shown as new .... I've been adding header photos to my old entries and accidentally ticked the 'publish now' box. it dates from march 2016! ... i'll try not to do that again.  Still getting to grips with the new system!

Well, I'm grateful it is being shown as new, having missed it in 2016. Looking forward to seeing those superflous truss rods disappear!  Btw, Tim V's B-set page was imported into gwr.org when his webspace got taken away:

http://www.gwr.org.uk/b-set-notes.html

 

The error list in the Airfix should perhaps include the incorrect bowing of the headstocks.

 

Your reference to 1'8" short buffers (in your text file) on the outside ends is interesting, but seems to contradict this blog's "replacing the outer end ones with long square shank buffer castings". Must admit I had previously assumed the outer buffers would be standard 1'10.5".

Miss Prism you are absolutely right about the buffers and I have  a set of sprung square shank buffers awaiting a swap with the rigid ones currently fitted.  And yes if I hadn't mentioned those awful curved buffer beams on the old Airfix chassis I certainly should have done! (I haven't checked that text file for a long, long time!!)

 

I am so glad that gwr.org.uk rescued Tim Venton's notes, they are such a useful guide as there seems little else about B-Sets out there!!

 

Now all I've got to do is pull them out of the box and finish them off (It was the bogies that I was going to do a bit more to, I wasn't happy with the mods I had done so far to those somewhat skinny (underweight might be more like it) Airfix mouldings and the replacement tie bars need to be higher up ....

Well I was going to mention the number of truss rods, but you beat me to it. Insert an emoji with a halo here, because I can’t. This issue has cropped up in another blog ( can’t remember which), so I happened to be passing Didcot one day and came to the same conclusions as you: two truss rods on ‘modern’ coaches of 61’ or less. One of the O gauge suppliers has incorporated 4 truss rods in their B set, so you’re in good company!

Truss rods !!!

 

Well it`s four from me !!!!!

 

Poor picture , but my vote is there is a hint of more than  two truss roads here ......

...and my  1980`s O gauge RJH  coach kits catered for four.......

Oh dear - truss rods!! Shame none of the originals have survived into preservation.  And yes that broadside picture of the E145 looks like there could be four. I've now cut the extra ones off!!!!
