    Okay. There's a lot to consider here. Robert's idea for glue on parts may be the best all around solution. I started testing different shapes over the classic chassis. I had no idea Marklin updated the chassis, which of course, complicates things. I would need to get my hands on one to test fit my designs. Ignoring the newer chassis for the moment, I've come up with something that may be good enough. If I make many different domes and parts and put them all on a sprue and make a brass base shell, voila.

    +1 Love it! Also of note the steam generator, bell, sand domes, steam domes, and smokestack are all in slightly different locations on the different prototypes, so everything would need to be on the sprue.

    Nice work.
    I have tried myself with the camelback.
    A 4mm 5 volt motor fits nicely.

    Rudy, ubiminor, very nice!
    ubiminor, I still have to finish mine and you already have one modeled up! Ah, the wonders of rapid prototyping.

    Thanks. It is actually not a real model. More a fit check item. It will take a lot more effort to make it a good model.
    But I stop here. I am not into American railroad modelling, though I was momentarily fascinated by the exotic ugliness (hence beauty) of the camelback.
    I have to get back into my own things.
    Anyway if anybody else wants to continue I am attaching the model. Feel free to use it, provided that the original source is quoted.

    I did this one before thinking of using another chassis! saddle tank Engine!

    Walt,
    I am already thinking of how I can modify your shell to create a Vulcan 0-4-0.

    Round 2 of revisions arrived in the mail. It's a plastic print. The model needed a few more tweaks so I adjusted things and ordered another one. The next one should be the final version. I gave this one a quick paint job just for fun.

    It looks already very good. The rivets look too big, but I guess that is because you will make a brass model of it.
    The lost wax process tends to shrink some details iIn fact the lost-wax process of shapeways has a 0.25mm +2.5%*length accuracy).
    Since they do not offer any model reverse reshaping service, I wonder how many prints in brass you need to do before tolerances are met.

    I created a Vulcan 0-4-0 version in Photoshop, I just need to remove one drive wheel and slide the last one forward one spot, on the chassis.
    I shortened the cab, raised up the coal bin, extended the water tank, and moved the compressor and tanks.

    Bit late on this one but if you do fancy the USRA 0-6-0T ivan does a very nice one on Shapeways that drops straight onto the BR 89 chassis

    [​IMG]

    mine are in FUD but i think he does it in brass as well

    search for Ivan Industries on shapeways

    he also does this 0-6-0T as well

    Nice. I think I just got into British Z. Where are the decals from?

    The British railways ones are the N scale ones from Fox transfers in the U.K

    the NCB lettering is an ancient set of shaded gold alphabets that were lurking in the decal files

    I've got another USRA finished in private owner livery. Like many I've ended up acquiring a lot of the Marklin BR 89s over the years so its always nice to find something to turn them into

    this one works the high line on Republic Steel although it is seen here on Cuyahoga

    Thank you Kev!

    Yes, I did find Ivan on shapeways and I am currently working on the USATC. Very nice, and with a bit of sanding (on the chassis) indeed pretty much a straight drop in.

    I use that classic 3-pole engine. Runs nicely with PWM. I sanded the top of the motor frame and some on the inside of the cabin, otherwise the shell won't quite fit. I had to remove the little plastic edge on the front the holds the Marklin chassis, for the same reason. It is dispensible anyways.

    Some sanding on the shell before painting. I found that difficult to do without removing details, tips are welcome. My chassis came with the standard red wheels and red rods. I painted the wheels black by hand. For the rods I used a fineliner.
    [​IMG]

    First paint. Lead strips ready for insertion, they fit nicely in the water tanks.

    Buffer front painted in red. Ready for now, stills needs lamps and lettering. I'm pretty satisfied with it.

    Btw, technically not a saddle tank I realise, so sorry if this is off topic for this thread.

    Matt,
    Nice work. I think your post is right on. I think this thread is dealing with switchers. It is also nice to see others working with Marklin chassis to create steam locos. I am currently working on the 0-6-0 Brooks camelback, and just started an 0-4-0 Vulcan.

    Thanks Dom for the appreciation,sorry for the late acknowledgment.
    I have realised that I never posted a video of this tiny loco.Here it is.

    I must say even in its unfinished state I find it very cute to watch.
    I really hope that somebody will make a real model of it.
    Ciao
