How much! The Cambrian C12 Dogfish Build

    Some more bottom rung of the ladder kit building from me!
    You may of seen my slow and evolving Airfix kit building in another thread in Area 51 so as then this is just an exercise to record the ups and downs and hopefully a half decent result.
    I did say over in my WTW No. 5 thread I’d get back to that but alas these have jumped the queue due to my Meldon layout build.
    To explain the title, I was sorely tempted buy the Kernow Models Heljan rake of 4 wagons K4103 Heljan Dogfish Exclusive Pack of 4 - BR Civil Engineers they would need back dating a bit but look rather nice but a 100 quid for 4 seems a lot. Only seems it probably not really!
    So modelling funds always tight I decided to build my own. Now I’ve only ordered two Cambrian kits so £50.00 equivalent in the pot.
    I thought I’d see what I’d be paying myself an hour to finish these and no doubt nowhere near to the same standard but a fun thing to do anyway. I get that RTR is never going to give you the same satisfaction of something you’ve built yourself and you can’t really put a price on that.
    On to the fun.
    So as before on my Airfix build these will be lunch time builds in the van on the makeshift work bench!
    The quality of the instructions leaves a lot to be desired in detail and clarity looks like a photocopy of a photocopy of the 20th photocopy and the download online is hardly better.
    There is a fair bit of flash to deal with along with stubs off the sprue.
    1st up the chute.

    By the time I’ve worked out which way to glue from a ref. Photo not the instructions were up to!

    That’s Day 1. Day 2 the solebars and headstocks glued the small end upside down as the instructions were not clear enough again photo to rescue the lamp iron should of been the give away. The axle bearings and buffers were before this but as you’ll see I’m again trying to save money.

    And there you are over an hour in!

    I dare say an experienced modeller would be 15mins? By now?
    I was tempted to build them in tandem but space precludes that.
    Fun though.
    Blummin hot today though had to seek out some shade by a stream in an attempt to keep cool.
    Stay safe folks
    Until next time
    Cheers

    This experienced modeller has built both Cambrian Dogfish and Catfish. They were the most difficult plastic kit builds I have encountered so don't worry about the time taken, it'll be longer and far more fiddly than any Airfix specimen.

    A novel idea, Ade.

    I like the thought of a mobile work bench: ‘....some shade by a stream....’. Nice :)

    Having built a few of these, I found that the best way to get a square chassis is to trim and file the moulded pips for location off and to replace the end platforms with slabs of 60 thou’ flush with the sole bar tops. I then reinstated the detail with 5 thou’ sheet overlaying the entire width of the chassis. I’ll dig out some photos later.

    Obviously that’s more work, but the first one I built (in my teens) eventually fell apart and got rebuilt as above. To be fair, they’re a brave attempt at DIY mould-making and the results aren’t bad, but something has to be done to increase the surface area of the structural joints.

    I've also built a few of these in the past and echo what others have said. A very difficult kit to build not made easy by the instructions and fit of the parts. I would recommend that you follow Adam's advice as the lack of strength in the 4 corners does lead to the wagons being fragile.

    Actually, it seems I was a bit less radical (I was thinking of the Mermaid). I squared the platforms off, took a big file to the detail and assembled them flush to the solebar tops.

    I certainly didn't bother with the pegs for the brakeshoes - adding brake yokes drilled through the shoes makes a world of difference.

    PS - the amount of epoxy under there probably helps, too...

    Wow thanks all for the comments!
    Noted Neil it does seems that way. Cheers Jonte
    Especially Adam fo the fab photos great build there, obviously a detailing kit or scratch additions, very nice, maybe one day for me but not during this build. Noted on the strengthening Adam and Chris.
    Right plastikard from Station Road baseboards As recommended by Chris on his thread needs loading in the van then for Monday!
    Below done before I saw the posts above.
    Ok we got from 1hr 10 to 1hr 34 just trying to get the platform parts files up tidy and fit!

    Next up some clamps and weld.

    Ran out of time to finish the smaller platform so just the headstock end welded till Monday.
    Here we are underframe not complete yet and 2hrs in!

    Again thanks for looking in.

    No detail kit Ade - I'm not aware of anything like that - though I chose to replace the handwheels with some very natty ones from Colin Craig which can now be had from Stenson Models. Just lots of bits of wire and some scraps of plastic strip. You other thing you can do - and would recommend - is to pack the ends of the hopper to hold it in place. I think a chunk of 60 thou' (1.5mm) thick sheet at the platform end is what's needed. The resulting additional strength is well worth it.

    Cheers @AJC yours is a great upgrade now I’ve studied mine by comparison!
    More weld on

    Tidied up the hopper and we are up to..

    9F899806-63C0-441E-9B25-AAF699E0B695.jpeg

    Tried it for size on the underframe will need work!
    D43F8AD4-FEA4-494E-9DE7-771511B90FB2.jpeg

    Then on the advice of Adam and Chris looking to beef the corners up a bit.
    Best compromise I think I could come up with to allow the brake shoes to go on, did think of chopping the brake shoes off and welding on the plastikard , what do you think? And of course epoxy when the coupling hook goes in. 816086DF-FE92-4419-89BC-92419C9E967F.jpeg

    We’re up to!

    I seem to remember having issues with all the hopper wagons getting the hopper to sit flat and level on the supports. Quite a tedious job working out how much to take off which. I did wonder several times if there was a way to fit the hopper first and then add the supports afterwards.

    Yes, there is - and I did it on at least one of mine - but you sort of need one fully assembled one as a datum! Trim the supports off before assembly and wedge the hopper in place by packing each end. I'll fish one of mine out of the stock box later to check by how much. You can then reinstate the uprights in T section from Evergreen or make your own from strip.

    Cheers Chris and Adam, I’m going ahead using your advice where I can but redoing the supports may be a step to far! Though I would need this one as a datum model anyway.
    Seems all I needed was to take a bit of the struts down into the underframe.

    117E6DA6-5924-49EE-A7A8-56CF7BD831B1.jpeg

    Decided the 1mm plastikard was not going to cut it needed 2mm I thought for best strength that would fit.
    So was looking for something I could do until 2mm plastikard was at hand.
    Vac cylinder filed up stuck together and added
    D4261BF4-7E56-459D-9964-6578A29A3ECD.jpeg
    Didn’t want to put the hopper on till the underframe strengthening was complete.
    Now we’re up to.
    0483F1E9-C4DA-4BF9-B727-BF7265EC33DC.jpeg

    Next up 2mm plastikard to hand and for the buildings I intend to make with Perspex I bought a sqawker I think it’s called and used it to cut the 2mm plastikard bit of a technique to it but safer and easier than a Stanley knife I normally use.

    The 1mm corner with the 2mm I changed to.

    Glued in space left for the brake shoes.

    8FA67B8C-0FAA-4D6B-A8A2-446F0AFFECE1.jpeg

    Now we’re up to ..... that does include making the 4 corner pieces.

    I've never built one of these kits in 4mm scale, however many years ago I did chop some 4mm Heljan ones around to make LT ballast hopper wagons.

    LT Hop Dogfish & LT hopper.jpg

    Now my 7mm Heljan Dogfish is going this way......
