BR Diagram 1/148 HUO 24.5 ton Coal Hopper

I managed to get the side stanchions fitted yesterday but as with the central ones, there were a few minor fitting problems, it's amazing how 0.2 or 0.3 of a millimeter here and there can can make all the difference between a perfect fit and a lot of hard work to make it look right.

I have now modified the drawings to correct these issues so hopefully the next one will be perfect !!!

 

I just need to fit the handrails and castings for the axle box and springs then this one will be finished.

The handrails, axle boxes and springs are now all in place so this one is ready for the paint shop. I'll send the drawings off and order a new test etch tomorrow.

Both castings are 51L, I found I have to bend the spring slightly so it looks more like it is on a loaded wagon otherwise the gap between the top of the axle box and the solebar is just too tight to get the spring in place.

 

The Timkin bearing was the most common one fitted but the boxes were changed during the lives of the wagons judging by the photos on Paul Bartletts website.

The new test etch has gone together well so far, the only real difference from the earlier etch apart from the fact this one is in brass is the fit of the side stanchions. I'm pretty happy with them now so if anybody wants any of these wagons please pm me for details. I'll probably be ordering everything from the etchers around the middle of next week unless something goes dramatically wrong with the rest of this test build.

 

Here is a picture of the revised side stanchions, the right hand one is the normal main stanchion and the other two are the most common centre stanchion variants.

I finished the chassis assembly yesterday so they are ready to have the hopper body fitted now.

The brake assembly can be fitted in two different positions, this was originally to accommodate both 00 and EM/P4 wheelsets but I tried some Alan Gibson and some Hornby wheelsets and found that even for a 00 wheelset you have to use the outer set of mounting holes to get the brake shoes to miss the Hornby wheels.

 

post-6711-0-83146700-1493979327_thumb.jpg

 

The left hand side is the Alan Gibson Axle and the right is the Hornby. If you use the inner set of holes for the brakes, the shoes foul the wheels as the Hornby wheels are quite a lot bigger than the Alan Gibson ones.

 

I will post some more photos of the build as I get time to do it.

A bit more progress, I mounted the hopper onto the chassis of the two wagons the other day and the first one fitted no problem at all. The second was being a real pain in the posterior till I realised I hadn't followed my own written instructions (familiarity breeds contempt syndrome !!) and when I had soldered the wagon end in place I hadn't made sure that the sloping part of the wagon end was inside the wagon side all the way down the seam, so the wagon end wasn't properly square and it didn't sit in the chassis floor properly as a consequence. Once I realised it was fairly easy to adjust, but another lesson learned.

 

I found the easiest way to hold the hopper in place as you line everything ready to solder it is to use a couple of elastic bands, but they have to be the same strength or the stronger one will pull the hopper out of line.

I added the components which represent the hopper door hinge/door opening components yesterday.

The hopper covers went on today so the wagon is starting to look almost finished now.

I will add more photos as the build proceeds, but so far everything fits as it should. If this continues I will order the etches which members have requested on Wednesday or Thursday.

I've now got the end and side stanchions on and they seem to fit O.K. These have all been fitted using a conventional soldering iron rather than my RSU just to ensure the model can be built satisfactorily in this way.

 

Progress has been a bit slow as my 'gammy back' has been playing up so I can't sit and model for more than an hour or so at a time or I end up in a lot of pain. 

 

I will get the etches ordered this evening and I should be able to supply everyone with the kits they have requested in a couple of weeks. There has been a lot of interest in the kits so I will contact everyone who has asked for any to find out which types of buffers they want, as I am sure I will need to order more from Dave Franks (LMS Models) to cover all the requests.

 

I will supply the etches in brass as they go together as well as the NS ones and are significantly cheaper so I can keep the kit cost down.

 

Here is a picture of the progress so far.

These two wagons are now ready for the paint shop. I fitted one of the alternative styles of axle box to these ones just to add a bit of variety to the fleet. I'll build a few more when the etches arrive next week and fit spindle buffers to them. I didn't have any of the correct type of spindle buffer left in stock when I made these ones, I only had the 16" head version available whereas this wagon was fitted with the 13" version.

 

I have fitted Alan Gibson wheels to the wagon to the left hand side of the photo below and Hornby wheels to the right hand vehicle, just to prove they will fit, but I think the Alan Gibson ones look much better.

I've now painted the four test build wagons, photos below. I still have not received the next batch of etches from PPD which is an unusually long time since they were ordered. I'll give them a call tomorrow to find out what is happening. My apologies to all those who have requested kits for the delay in supplying them.

These wagons would have been fairly new for the period I model so I have painted them in a dirty but not decrepit state. The Photos on Paul Bartletts website mostly show the wagons at the end of their working life so they were in a rather sorry state with lots of rust by then.

Very nice looking wagon and kit. Very tempted to get some. Below are some of my pics of them in later life, mainly carrying coke in South Wales in the mid 1980's.

Hi Paul

 

They are very useful photos, thanks very much for providing those, it is much appreciated. Would you mind if I added them to the instruction CD which I send out with the kits, they will be very helpful when it comes to painting the wagons.

No problem at all Ian. Add away.

DJM have now announced these in 00 and N, at CAD stage, and will go into production as a crowdfunding venture, provided enough interest is registered. See  http://www.rmweb.co.uk/community/index.php?/topic/127705-new-oo-gauge-huo-n-gauge-245t-hopper-wagon-crowdfunded/&do=findComment&comment=2908924

 

Don't worry Ian, I still prefer thin metal to thick plastic for hopper wagon sides!

Probably only thee and me though.

Hi Mike

 

If they are only at the CAD stage, they probably won't turn up for another 2 years anyway. I've just received the first test etches for a 7mm version of the wagon today, it looks like it should be fun to build. I was asked for it as a commission but should be able to offer it to Forum members if they want some.

 

Have you finished the coke hoppers yet?
