coombe junction - Hoodies...Part II...


bcnPete

1,693 views

Update - Still suffering from Expo fever and thanks to all the encouraging comments from my last post of my first wagon etch chassis build, I was keen to progress it.

 

The body is a Parkwood kit and a number of modifications were required to get it to fit better on the chassis. Firstly, the width of the buffer beam was reduced as this would have made the wagon too wide. Secondly, the overall length was trimmed to fit better. Thirdly, the moulding on the buffer beam was removed and a 2FS coupling hook was added.

 

I overtrimmed the base so had to fashion a new one from plasticard but this will be covered with a 'hood tarp' eventually. Buffers are from the 2FS shop and the chain for the 3 link was found in a model shop here amongst all the detailing bits for boats (canons, anchors, me hearties!) I would like to couple these hoods as fixed rakes of 8 wagons with 3 links between and DG's at the outermost ends.

 

There still remains to do the correction of the brake lever, addition of brake gear, vacuum cylinder etc and clean up and paint but I feel ready to take on the next 17 now...

 

I attach a few pics (sorry if a little out of focus) and the last one is a comparison of my new 2FS hood with my previous 20 year old conversion of a Peco 5 plank into a hood...these will now be consigned to the skip :O

That really is a fine looking wagon...Im not sure if i could do that though! Only one way to find out I guess....

Mickey - Thanks - I am sure you could - I was putting it off until my ham fisted soldering efforts improved...but I guess that comes with practice so you just throw yourself in - the learning curve is pretty steep - Pete

Evening Pete,

 

Really enjoying this account of building these Clayhoods.

 

Your first wagon is coming along nicely. The chassis looks neat and you've done a grand job of mounting the body on to it.

 

As a matter of interest, how are you planning to do the hoods?

 

As you say-'Only another 17 to go!'.

 

Cheers.

Nice work Pete. It's amazing how much difference the right wheelbase makes.

Pete,

 

This does really have the potential to be a very nice wagon, but I fear you need to go back to the drawing board on the question of how to trim the sides and ends to fit the chassis.

 

From the picture of the kit, it appears that the ends are intended to fit between the sides, with the sides resting on the extended ends of the buffer beams. This way you would get the hinge bar above the end door to line up with the loops on top of the sides and the corner plates on the fixed end to line up correctly. Perhaps the problem is accentuated because you have the ends the wrong way round?

 

Sorry to sound so negative, I'm really looking forward to seeing you make a good job of these wagons.

Mark - Thanks - I think I once read that masking tape makes a good material for the tarps - there will be a few experments first no doubt.

 

Don - Thanks also - I look forward to the day when I can run a rake behind a 25 or 37 and restart the train and see the 3 links working under the strain!

 

Nick - Thanks - I see what you mean...let me just rewind a little and share my findings to date on this...

 

The main problem, for my situation, is that the Parkwood kit is an N gauge kit designed to fit on a Peco N 9ft chassis, not a 2FS chassis. The first time I built the kit (refer to the pic on my Hoodies Part I post) it was built as per the instructions, with the sides resting on the extended buffer beams as you note above. The problem is, when you locate this on a 2FS chassis the body is far too wide...and its quite evident as the the protuding metal side ribs should pass the solebars...but the solebars end up about 1mm behind the ribs (each side) The other problem is that the length of the 2FS chassis does not then fit between the buffer beams. I tried to cut off the Parkwood buffer beams but its difficult as the metal ribs extend below the buffer beam at the non door end. So...looking at the prototype (thanks to Kris for his detailed photos on my RMWeb 3 thread ;) ) I noticed that the buffer beams on the Parkwood kit were overlong...hence my cut and trim solution.

I think you are right about the ends being on the wrong way and I will correct that, but I guess when mix and matching an N gauge body with a 2FS chassis, compromises have to be made and I felt that the wagon looked better with the ribs tighter to the solebars. What we really need is a decent clay hood in 2mm scale...I am assuming Bachmann will one day release the 2mm version of their 4mm clay hood...unless any small suppliers out there fancy a challenge?

 

I hope this clarifies why I assembled the kit in this way. That said, this morning whilst transferring the wagon back to the layout, it rolled off my test track to the floor and smashed into a great number of pieces...so that's two kits ruined...my rakes will be pretty short at this rate :( :(

The chassis looks very well put together considering how tiny this is! Sorry to hear about it coming a cropper this morning!

Now that's a shame that the rakes are getting shorter. The chassis looks smashing (possibly the wrong word in the context but..) in the pictures. I can see what you have done with the body to get it to fit. There are always compromises to make I think. I like the three links, they look the part.

Please ignore the follow waffled suggestion for the plasticy bits, as it comes from a bit of guesswork from the pictures and may or may not work.

 

Looking at the pictures I think that the bodies will need a little bit of work to get them to fit together nicely. I can see what appears to be a slight mitre at the edge of the ends and am assuming that this is mirrored at the ends of the sides. I don't think that the parkwood moulding is particularly sharp in this area. If this was sharpened up then the body would come together better(I find a quick couple of swipes with a file normally does the job). This obviously means that the chassis is then going to be slightly to long for the body (oh the joys of mixing and matching "N" and 2mm). A fraction off each end of the chassis will work here, or a little off the insides of the buffer beams.

 

Is there any hope for the bent one?

p.s. if you need more photos I can pop down to the SDR and see if I can find the wagon and fire away with the camera.

James - Thanks - its not the first time my 2mm stuff has had an encounter with the floor - when will I learn?

 

Kris - Thanks also - I shyed away from the chamfer the first time I built the body but now its time to rethink it and it might be the best solution for the 2FS etch...I think the analogy at the moment is 'nice legs...wrong table top'...so its worth trying using another body.

 

Thanks also for the offer to revisit and fot the hood although I think its not neccesary as the detailed shots you took before pretty well captured it all.

Thanks for clarifying the problem, Pete. I hadn't fully worked it out from the previous blog entry. Since I read your reply this morning I've been wondering about chamfering the sides and ends, thinning the buffer beams and/or shortening the chassis, but I see Kris has beaten me to it :) Hopefully, you can find a compromise. The buffer beams do look a bit too thick, so maybe it can be done without losing the fine rivet detail on the solebars.

 

Still in nit-picking mode, the photos give the impression that some of the axle boxes are upside down. The tapered part should be at the top. Mind you, I realise that what I am looking at is about four times life size and once the solder is cleaned up and its had a coat or two of paint you'll need a magnifying glass to see them, let alone which way up they are.

I've just looked back at the photo's I took of one of these, that Pete mentioned earlier. The rivet detail is very hard to see. Given the normal viewing distance that you'll see these from I don't think that you'll see it on the wagon anyhow.

 

Pete - I assume that you were going to add the door stop strips on the chassis but were wanting to make sure that they lined up with the doors. I know that some of the wagon chassis come with these, if not they are very easy to make with a bit of scrap etching from the chassis build.

Nick - Thanks - I think the chamfer and the thinning of the buffer beam is the way to go as suggested by Kris and yourself. In absence of a 2FS etched kit then compromises need to be made...but it would be nice to improve upon my first attempt.

 

Your right to point out the axleboxes too - Doh! The Bcn heat is getting to me B)

 

I think all in all, what with the body, brake lever and axle box issues, then dropping this wagon this morning was no bad thing :lol:

 

The remedy: One large glass, fresh lemon, crushed ice, Bombay Sapphire and a splash of tonic...I feel better already...

Kris - Thanks - From discussions on my RMWeb 3 thread about this, the chosen 2FS 9ft 16T mineral chassis was deemed the most suitable - I have already removed the single door stop from the chassis and was going to add the two stops from scrap etch or plasticard at the end of the build.

I've got a vague memory of those discussions. Personally I would go with the scrap etch option as it will be much stronger than plasticard.

 

Enjoy the G & T - I think that I shall soon be following in a similar route following the day that I have had!

Hmmm !!

 

An r-t-r model or complete kit for a 2mm scale Clayhood/fit .....

 

Given that the things tended to run about in Looong rakes, and a fair few people seem to be "into" such things, I imagine it wouldnt take to many people to run up a fairly substantial order...

I wonder if its possible to commission/persuade/beg some nice manufacturer to produce such a thing??

 

I know next to nothing about such production but I bet somebody on RMweb does.......

Mickey - Agreed - I believe Mevagissy models used to make an N gauge clay hood...I think it is adapted from a Peco 5 plank...nice model...but sort of what I had done 20 years ago and was trying to move on from.

 

Who knows if and when Bachmann will ever produce their 4mm version in 2mm - I guess another option would be to produce artwork for a 2FS etched kit which would fit directly on the 2FS 9ft chassis without modification...but that's beyond my skill set at present.

I have a feeling that designing the etch for the body should be reasonably straight forward, but if you were to go down this route then I think you would also want to look at doing the correct chassis rather than just going for the closest fit. It might also be worth considering the previous version of the clay hood (O.14?). The correct chassis is available for this one I think.

Nice model. I have a bunch of these in my gloat box and one partially finished one...

 

The place where I ground to a halt was buffers. Most of the prototype photos seem to show china clay wagons sporting self contained buffers... which don't look much like any other kind of buffer.

 

So far I haven't found a source for suitable buffers so am contemplating getting some turned... quite a lot of them actually because most of the cost is in the setup.

 

I expect that these may appeal to other folks because the GWR used similar buffers on many wagon types. I also noticed that the buffers on Grampus wagons are quite similar. I talked to Mr Stubbs at the Expo and he didn't rule out taking some into the shop.

 

The first step is to do a decent drawing, so I'm wondering where to find a real clay hood so that I can take a tape measure to the buffers. I remember a couple at Wheal Martyn museum but it'll be a while before I can get there... plus I can't actually remember what buffers they had.

South Devon Railway has one that has been recently restored. I believe that this is the later BR version rather than the GWR one.

Thanks - a bit tricky to see in the photo but I think this one has the SC buffers. Still a long way from me though, so may mean a wait till late August before I can take a tape measure to one of these :-(

Kris - Your right - If you choose the etch route then may as well correct the chassis at the same time - still a little beyond me at present - I need to make a lot more etched kits first to be able to understand how they go together.

 

D869 - Did you see the close up photos Kris posted on my RMWeb 3 thread last year? I recall there was a shot of the buffers. How did you get on with the Parkwood body - same issues that I had?

Actually I dont recall doing anything to the body other than minor fettling. I think I had to file a bit off the end of the chassis to make it fit between the Parkwood buffer beams (or maybe that was a completely different wagon - not sure). My chassis certainly doesnt have any kind of buffer beam remaining.

 

I had another look at your pics and think I can see the difference - you've attached your ends outside the sides. Mine are inside the sides, so the buffer beams end level with the side planking.

 

I took the calipers to mine - 15.4mm wide inside the body vs the prototype's 7ft 7 1/4 inches, which isnt far wrong. Outside the body is 18mm vs the prototype 8ft 7, which is a bit further out, probably because of the thickness of the sides (which don't appear to be the same as each other). Length-wise it's the same story - spot on for 2mm scale inside the body but 0.8mm too long over headstocks.

 

Looking at a prototype photo, the ends of the buffer beam could probably use some attention with the file so that they resemble a steel channel instead of a lump of wood. I've also soldered a couple of door bangers to the chassis from N/S strip... which just leaves those pesky buffers...

 

Sorry - I couldn't find the post from Kris - could you let me know the precise URL please?

Any photos to show? Sounds interesting.

 

In terms of the dims, I guess until a 2mm hood kit is available, we have to compromise on length v width. I will revisit my one and try and mitre the sides and ends, thin down the buffer beam and see how that looks - I may as well try to get one to a stage I am happy with before I build the other 16

 

Trouble is...the Spanish heat has now killed off my modelling mojo :rolleyes:
