New testing necessary...
With new wheels come new problems!
For the redesign of my Ivatt Atlantic I have to test the chassis another time. Again I use blind drivers in the middle which worked for my earlier version so I have no doubts it will work here as well.
New problems:
- the running-surface of the 3D-printed XXL wheels is thinner than that of the BBB XL wheels (just like Lego's blind drivers are thinner to make room for the flanges of the other wheels) which means the mechanism will have to be more precise to keep the wheels on the tracks in curves
- with the drivers being bigger the distance between the drivers' axles is bigger too. To keep the distance to a minimum though it's uneven and instead of 6 stud's it's 6 1/2 studs. With some tricks here and there this shouldn't be too much of a problem though.
The redesign made it necessary to have all wheels (tender and engine) 3D printed. So this engine (if it will be done some day) will only be possible thanks to this technology :)
