Here my intention is to show the results of testing the chassis on the track. Unfortunately the videos are reduced in resolution from the original made on Iphone 7. I have asked help in Blogger Forum on the 08.05.2017 , but no answer with a solution so far today, the 22.05.2017. The same videos can be seen in good resolution here dated 08.mai and 18.mai:<br />

Refering to my post from 16.april 2015 about Microantriebe/KK Producja:<br />
<br />
Last week I received a package form KK Producja. I was impressed not
only about the fine products, but also of the very clever and safe
packageing. First an envelope with inside air bubble plastic sheet.<br />
Then a wellpaper box, then platic bags for each part, and inside this a
laser cut veneer made to fit the part, again wrapped in clear tape.<br />
<br />
See picture.<br />
<br />
Also I had a very good contact/conversation with the firm in advance of
the ordering/delivery. This firm have so many interesting products for
us small scale modellers. Good to find they have improved in their
earlier weak sides (in my experience), communication with the customers.<br />

The aim of my first project here is :<br />
<ol>
<li>To experiment with 3D printing</li>
<li>To experiment with small driveunits/chassis for N finescale</li>
</ol>
Starting point is a N scale kit from Möllehems Gaardsproduktion in Sweden <a href="http://www.mollehem.se/">www.mollehem.se</a><br />
The prototype design was made by Hilding Carlson in Sweden. I Norway we had three at NSB and one at the private Askim-<span id="goog_910629917"></span><span id="goog_910629918"></span>Solbergfossbanen. The NSB railbuses was typically painted redbrown with a yellow stripe. The Solbergfoss railbus was painted silver. Today this one is preserved by NJK (the norwegian railway preservation group) <a href="http://www.njk.no/">http://www.njk.no/</a><br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjZBr3rNcPVyASzk0YEvaqm7nlo5oHSQ5rMpBKHx-gfl8UZr2qDw0r_9yyIoNKyIUJCCGCHyTMqvbYqTod7G-NJKJbJf3uX6NoT0njEtPn7VVhS6KIoPTBTecQpN4GDw_BeiMiXOjQcAZA/s1600/00011245.JPG" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="214" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjZBr3rNcPVyASzk0YEvaqm7nlo5oHSQ5rMpBKHx-gfl8UZr2qDw0r_9yyIoNKyIUJCCGCHyTMqvbYqTod7G-NJKJbJf3uX6NoT0njEtPn7VVhS6KIoPTBTecQpN4GDw_BeiMiXOjQcAZA/s320/00011245.JPG" width="320" /></a><br />
The kit has a quite nice plastic superstructure. The chassis is also cast in plastic with a Mashima motor and NEM wheels. I have not tested the chassis / drive because I wanted to try out some ideas about making a chassis in 3D printed metal and I wanted the finescale wheel standard. I also wanted to see how a 6mm dia motor behaved in this model and I wanted free see through windows. On top of that I wanted DCC + sound +light<br />
<br />
So far I have designed a new splitframe chassis / drive and got it printed in brass from Imaterialise <a href="https://i.materialise.com/" target="_blank">https://i.materialise.com/</a> . From Shapeways <a href="http://www.shapeways.com/" target="_blank">http://www.shapeways.com/</a> I have got printed in FXD (Frosted Extreme Detail) a two part pivot for one axle. Only the rigid axle will be driven. In POM I have turned muffs for the split axles and pins to connect the two chassis halves. So far this have worked out well.<br />

Here is a picture of my .STL file for 3D print. It is massive for weight and split for good pickup of the current via the wheel axles. There is a circular room in the middle for the 6mm motor. Diameter is 6.4mm to make room for isolating the motor from the chassis. The small circular opening is for mounting a compensating device for the non driven axle.<br />
This have now been adjusted to a rectangular hole by filing. <br />

The 1mm dia axle is not separate, but turned integral with the wheel. It gives a wobblefree wheel. Between the frames is a 6x12mm motor from Mikroantriebe with worm (1:18) The white bands are turned from POM plast on my lathe, 0.2mm thick. The decoder is from CT but will be replaced by a CT sounddecoder. Under the frames : The two taps to assembe the frames are turned POM and the two part pivot for one axle 3D printed from FXD<br />
