New loco from Macton Loco Works

For discussion of the issues faced when building a model or layout - how to replicate wood, what glues to use, exactly how much weathering can a Gnat take, a good source of detailing accessories - you get the picture, I'm sure.

New loco from Macton Loco Works

Postby michael » Fri Nov 17, 2006 5:32 am

With all due respects to Jim Snee The locomotive engineers at Macton went to work overnight and came up with this railcar.

It could be a printy fairly quickly I'm sure If you need the file to convert Jim just give me the word.

If you can guess the origin of the design then I will send a glossy print of the root

No Mr Bennett you cant guess you gnow too much. :lol:

New Speeder

I like it Michael BUT It looks a tad small. On my screen it's showing at about 1.1/1 and I can't see how figures will fit :cry: .
I'll reword that I can see how figures will fit - surgery again :lol: :lol:

Why do people around here always say that when I know the answer, but never when I dont :) . Just so happens I have one of the originals hanging on my wall :)

What 'railcar' :?

I can see a drawing with pictures of two locomotives:
Bonnet end and top of a green Silva Springs loco, and the side and end of a red 'caravan'.

If you are implying that by giving a Silva Springs loco an 'overall cab' makes it a railcar, then I've got to review my definition of what railcar means... I generally take it to mean a self propelled passenger carrying vehicle - and I don't see any room for any passengers.

Unless you mean it's a 'Heinkel/Meshersmit' (not sure of spelling) trike type thing converted to rail use - in which case there may be room for one passenger?

I make it six-ish feet long by two foot six wide, which is about the size of some of those tiny Japanese railcars (I used to have a booxmark of a printy for one but I've lost it). Steve is obviously in on the secret, which makes guessing kind of risky, but assuming the short bit is the driving cab, by Exbury standards you'd get four standard passengers, a family of two adults and several kids, or two large people in the other bit. In my book that makes it a railcar.

The printy for the japanese railcars (there were 2) disappeared a couple of years ago Andy, they were here http://www1.seaple.icc.ne.jp/nkoizumi/ , I certainly cant find them now.

Getting back to Michaels, maybe a covered speeder would be a better description :) . It could do with being widened, I think Jim's worked out at 4 feet wide, though it is possible to comfortable fit 2 adults into 30 inches wide, then it could easily seat 4 people, with the engine tucked away under the seat.

Yep, you're right, Steve. I may have a copy cached somewhere, becuase I remember printing the blue one out and never building it. Finding one picture of unknown date on my 160G extrenal backup might be a bit tricky, though.

However, callously breaking the frames to get this url:

http://www1.seaple.icc.ne.jp/nkoizumi/kisotour.htm

makes the point. Top left is an open-sided version of the Kiso railcar (I think Joe Works did a kit of one with solid sides, looked for all the world like a VW camper van.) Took me longer to find it than it should have, because I got distracted by the Kamaishi mining section. I'd forgotten the mineral water bottling plant :)

Along way to go, but a first attemp at a body shell out of gummed strip.

still needs sideskirts and more filler but i think it'll work chasis is a percy.

That, Michael, is so sneaky that I suspect we'll have enough for a Gn15 Railcar Rumble any minute now. I have a couple of the vanilla 040s like Percy, picked up off ebay to make tram engines before we decided on gnine for the mixed freight layout.

Now to find some butcher's tape.

I guess that asking how you got the finish so smooth is going to turn out to be 'loads of practice? :)

That is a really cool idea.

Michael,

As me old man would have said 'thats wizard'.

I watch your progress with interest. I'm not sure I understand why you cut the moulding in half? Was it:

- an early failure?

- Do your body sides have an undercut?

Yes Gerry is right, I concidered a tumblehome but decided on straight. I put the hole in the block so I could blow air in to release it. however it did stick.

I thought that I had enough vaseline on the wood former even so it was not going to come off unless I cut it. I glued it back together right away with ACC, getting it smooth was simply layers of putty and dark paint. The putty fills the pits and hollows the dark paint shows them up as you sand it smooth after each application. The thin ACC almost turns the paper into plastic anyway. Dodgy stuff to use though, you need good ventilation better yet outdoors, although in my case that's like working inside a large food freezer these days. overall there is about 4 layers of gummed paper.

Gerry if you shellac the body the damp wont affect it, I made a model boat this way when I was a lot younger.

This method doesn't quite have the finesse that Christoph gets with his paper and card. It is much more bodge like at least that how it feels.

I will do some practice with the application of the paper, take a bit more time and look at the shapes of the gummed strip pieces, that will help to make a smoother shell.

Damp - not really!

Postby Gerry Bullock » Sat Nov 18, 2006 6:32 pm

My comment was rather more comfort related - in the Heat of an Adriatic Summer you'd need an Open Cab rather than the closed one of your speeder.
Still I suppose it could be built with no glass :lol: :lol:

Paul, Gene, Simon thanks for the kind words. I think that there might be some good possibilites in this method, Gerry's comment about the open air has given me an idea about how to do the window dont know why I didnt think of this before I will take much more care with the paper on the next shell, see if I can build it leaving the openings for thewindows instead of having to cut them out later.

Interesting that you would show that Simon, I was in the assembly shed all day working on a more refined version of the railcar.

I went with plastic for #2

Image

I used a method called drape moulding very easy way to get thin compound shapes I used some very thin white styrene scraps for the first tests. The first picture shows some of the blister pack from Percy and it worked very well, I was thinking about making the shell clear then just painting the body leaving the windows clear. I even did a few with the flat top cut out of a plastic egg carton.

Image

I made 2 drape sheets one for the top and ends and one for the sides. I just turned the wooden former that i used for the gummed strip around and made a couple of drapes for each side, I am using a good hot air gun but a good hair dryer would also work on thin styrene say .010" The square of plastic is held in place on the drape frame with masking tape. As soon as it is hot simply push it down over the mould, in this case the wood form.

Image

after the sheets were made I used the #11 to knife around the form so that i had flat bottomed shapes to work with.

Image

I drew on the windows with a pencil and used a drill in the pin vice to drill a series of holes around the inside of the window opening, then chopped this out with a trusty #11

Image

Dry fitting the sections together, using this method there are many possibilities for where to put the joints. it is a good idea to make a bunch of spares sheets because the stretching of the plastic is a bit of a hit an miss thing regarding the consisitency of the thickness. and when you cut them out some places are just too thin. i also pushed the drape frame down a bit to far in retrospect.


Image

Bertrand did get a suprise when he came on for the evening shift the boys in the back had pushed the new railcar out to get a better view, things are a bit crowded inside. They still need to cut out the doors and rear window yet.

Michael,

Where it is a bit too thin all I do is cut a suitable section from another mould and glue it inside. Lining the whole thing like this makes it very strong. I use the clear mold as the 2nd inner liner again cut to fit as required.

Thanks for that Paul, I hadn't thought of doing that, but you have also just given me the clue :idea: to glueing the body together, as it is just held with masking tape at the moment. I will make some tabs from some of the other sheets glue them into one side. Sort of like the little tabs and dimples in a plastic kit, which is what I have made myself really isn't it. :)
