Great work!

I agree with all - just mind blowing

Peter,

always a pleasure to follow your posts. As the others said - mindblowing handcrafted modeling. How coarse the printed parts' surface looks beneath your hand made items ... I do admire your patience with modeling and the results are fantastic from shape to coloring.

How did you make those gear wheels, especially the sloped differential ones?

That's a tedious and time consuming process, as I do not own a lathe or such equipment (unfortunately). My old drilling machine is my lathe and the major challenge is to cut out exactly the right cone sector with the corresponding diameters (i.e. 8.5 mm).


The sloped back of this gear wheels is made up of several layers of plastic sheet discs, shaped to the desired form with a sharpe knife blade and sandpaper and ... Tamiya putty.

Peter,

how about the cogs? How did you make them? Wrought material with spacers of same diameter? Did you chose the cone's diameter according to the wrought material / i.e. number of cogs required?

Thanks,
Volker

Hello Volker

It isn't as complicated and professional as it seems. First step is to positioning the cogs (in this case Slaters .040 x .040" strips) with a drawing underneath on about 1/4 of the cone with the help of spacers of same diameter. This is also done on the opposite side of the cone. Then I filled the the spaces between those cogs with the same strips and covered that section with Tamiya tape. It is important that the tape should be firmly rubbed an those loose strips. After removing it there is a conic section of cogs on your tape and can easily placed and glued where desired. If the space is slightly wider than calculated you can stretch the tape carefully to make it fit.

Not easy to explain, but I hope you understand.

Basic modeling techniques with outstanding results. -- Russ

I've just visited Dave Fishers thread on his SP Narrow Gauge #18. That's what modelmaking is!
After having surpassed the first shock to some extent, I nevertheless decided that I will not throw my own project in the trash... I will move forward courageously and try to improve my skills step by step 
More and more I am suffering from the complexity of the whole arrangement. As there are no plans I have to work from the few contemporary photos. All components need to be checked repeatedly and, where necessary, adjusted after every step, after every new created part.

Here the current status of the project. All parts are still loose fit!

Nothing is wrong with your skills. -- Russ

[Ray Dunakin]

I agree with Russ! This is marvelous work.

Peter I have just spent a couple of hours reading this entire thread, I would agree wholeheartedly that you have demonstrated great skill! your model shows that a great deal can be accomplished with the minimum of tooling. Like others have already mentioned I would be very happy with the results you have achieved on my own work. Thank you for picking this model up again and continuing with your researches on the fascinating project.

Last weekend I took the time for air-brushing! This is not an easy task, when you don't have an own hobby room. So, in wise foresight I sent my two ladies go shopping in town ...

"What color was the used materials?" With regard to the stone abutement, this question can be answered easily, as the stones had been quarried in nearby southern Germany and there are some original pieces still there.
However, it is more difficult to archieve a coherent picture regarding the colours of the machine components. The sole source that could provide at least some basic indications on colours is a prospectus for the 25th anniversary of the installation from 1890.



Thus, obtaining accurate color information was impossible, I listened to my heart and decided for a bluish light green hue. The Farrow&Ball colour chart describes this hue romantically as Oval Room Blue (a typical late 18th, early 19th century colour) - that's what convinced me.
I am very encouraged by my first attempts (In the first picture it looks too bluish - I am a terrible photographer ) and I will continue in this direction. Here some pics, before and after some weathering here and there - still too litte rust stains.





Cheers, Peter

Peter; your skills are incredible!!!! I still can't believe you don't have a lathe! I too am glad you're again working on this project. Thank you.....Allan

[Chuck Doan]

That is so excellent! I too am glad to see more progress.

The results are beautiful. Try using more lights when you take photos or else shoot outdoors. You may like your photos more. -- Russ
