DJH U Boat build, first time loco building


Recommended Posts

Morning one and all, for the first time ever I had a go at kit building a loco, the model in question a DJH U Boat with the 3500 gallon tender. Now I've never touched a soldering iron before yesterday, very steep learning curve, and massively enjoying it!

 

So far I have started on the tender body, and the tender chassis, and I must admit soldering wasn't as horrific as I imagined, and as I said really enjoying it :) plan for tonight while Kate watches that wonderful documentary on BBC1 tonight (yup eastenders) will give me the chance to hopefully solder but the chassis and add the brake set up on to the tender :)

 

Let me know what you think guys, it's far from perfect but I'm learning so much from it !

 

All the best

Matt :)

What is a U boat in this case? I'm aware of submarines and General Electrics 'Universal' series of diesel locomotives, but what is this one?

it is a Southern U class. Maunsell design. I can remember them being used on freight and passenger duties and one or two worked to the end of steam.

 

I think it got the 'handle' U Boat from the Mid Hants Railway. These are pics I took of it some years back

Be wary of design details between 1638 on the Bluebell and 31806 (now on the Swanage). 31806 is a River rebuild with the running plate set lower with larger splashers. 1638 is a standard built U boat.

  

And 31806 has a BR modified front frame too... Just to confuse matters.

Mmmm...and Rebuilt Rivers had wider footplates - six inches wider - than new-build "U"s.

Cheers for the replys guys :) for the poster who was thinking about having a go, do it bud, if I can solder anyone can :)

 

My original plan was to do 31806 after having a footplate ride on her at swanage but seeing as this kit would require a lot of work to do so, I'm going to stick with one of the locos that is represented in the kit, still a bit more research to be done on which loco in particular I will be doing. Last night I got the chassis for the tender all soldered up, now I have my first question, you all knew it was bound to happen soon!

Okay I have to solder on nuts to part of the spacers, what's the best way of making these line up, I used a cocktail stick but they aren't what you'd call bob on, the screws go in but are a bit of a struggle. Any advice on how you guys do it?

 

Still enjoying it though, might have a new pic later on :)

 

Many thanks again,

Matt :)

....My original plan was to do 31806 after having a footplate ride on her at swanage but seeing as this kit would require a lot of work to do....

For 31806 and any of her wider sisters, you'd need to build a hybrid, using a mixture of DJH and parts from the SEF "River" tank kit. I think the chassis was five inches longer as well, but all at the rear.

 

To this day, I've never seen one built in 4mm scale. Loads of "N"s, new-build "U"s, and a few N1s and U1s, but never a "rebuilt River".

Sorry guys no more work done to the model this evening, too knackered from pounding the rails at work. As I said I would love to do 31806, but maybe this can wait until my modelling skills have improved :) as to this model, I know I have quite a narrow window in which to model on, some research will need to be done, me thinks :)

Your method obviously works.  I tend to use the screw to hold the bolt down, but before that I put a small amount of oil on the threads.  Tighten it down and solder the nut.  All being well, you haven't soldered everything solid - been there, done that, but only after forgetting the oil.

I shall keep that oil method in mind, I did try using a bolt to get it straight and true, needless to say I now have a nut soldered to the bolt lol, learning all the time I go! Brake hangers have now been soldered to the chassis, coming together slowly, hope to get a bit more done tomorrow :) footsteps hopefully going on tomorrow :)

So a little bit of progress with the U boat today, what I've learnt so far today, steps are and absolute pain in the arse to solder, a job you need about three hands for! Top plate hadn't been soldered in place yet, few more bit to do before his happens, jobs for the rest of the day get the rest of the steps in, and maybe the buffer beam in place. Placed it along side a Bachmann RTR N class, pretty happy with it so far :) really am enjoying myself making this model :) oh and surprise surprise, soldering iron sodding hurt when they come in contact with fingers!!

Fortunately most of us have reflexes that ensure the iron doesn't do any lasting damage.  I've sometimes had to grit my teeth in order to make a joint where my fingers are a bit too close to the iron.  All part of the game.  I've done far more damage to myself with knives.

Nelson, and Matt  :pardon: , the advice I always give is to have a look for Iain Rice's books on chassis construction and loco building.  Iain's book on chassis construction has a comprehensive section on soldering and advice on equipment and dodges.  These are published by Wild Swan and, admittedly are somewhat dated.  They are a good read however.  http://britishrailwaybooks.co.uk/books/wildswanmodelling.php  The books are out of print but you may find copies second hand.

 

Another thing to try and get is Right Track 1 & 2 DVDs (Activity Media) on loco kit construction by Tony Wright.    http://www.model-railway-dvd.co.uk/right_track1.php

Agreed on this one bud, smaller bits can be a bit sore but I'm learning all the time and sometimes things have to hurt to learn lol,

 

And I'd fully endorse a DJH for a first go, start with a plastic wagon kit and move on up from there :) if I can do it buddy anyone can :)

 

All steps have been soldered on to the tender, just the axle boxes, handrails, and crew boxes to fit to the tender, and it'll be pretty much finished, then it'll be on to the loco itself and squeaky bum time!!

 

All the best

Matt :)

Bit more progress this morning, steps all in, as is the buffer beam, thinking of adding in sprung buffers, as they would look a bit finer then the white metal castings. Axle boxes in too, it's amazing how much they can change the appearance of the model :)

 

All that's left to do is add the handrails in, solder in the top plate as this is just currently placed in rather then soldered, and add the brake rigging, plus one or two more bits to the front of the tender. But she's getting there :) pretty pleased with it so far :)

Singed fingers are all part of the joy of soldering.  However, one of the real tricks of soldering is to discover all the devious ways to hold the work in place, without having your fingers in direct contact with metal that is rapidly getting warm. Wooden cocktail sticks and coffee stirrers have a multitude of uses.

Good luck with the project

Best wishes

Hi Matt, I agree with Eric, wood is good, I screw half clothes pegs down to my formica soldering surface as clamps. They hold things nice and steady and are easy and cheap to replace when they get a bit charred.

I also agree about the burnt fingers. If you watch Tony Wright's excellent videos you can see molten solder actually touch his fingers. Ouch! Not necessarily recommended...

Hi Matt,

 

I built a DJH U-Class a while ago, fully written up on my Workbench thread here:  http://www.rmweb.co.uk/community/index.php?/topic/2359-dlts-southern-locos-adams-a12-jubilee/page-12

In the end we only used the DJH loco body, and fitted it to the Southeastern Finecast loco chassis and a spare Hornby tender (cos at the time DJH didnt have the tender we wanted)  It was a bit of a labour of love, but I was very pleased with the result.

 

Hope this helps,

Dave.

Eric and Simon, some very helpful hints there guys thank you :) no burnt fingers today, although the steps on the back of the tender were certainly fiddly to fit and needed about three hands to do, but got them on there okay :)

 

And Dave that's truly stunning mate, a lot of work put in but well worth it for the result :) have bookmarked it so I can go bank for reference :) no doubt I'll be asking you plenty of questions in due course!!

 

All the best Matt :)
