New version! Now, the main body is only 4x6 studs:

This redesign is absolutely brilliant! Time to make a couple dozen
automated switch points...

Thanks Chris, but apparently this design as it stands is too sensitive to the
clutch strength of the components being used. Yesterday, I ran it over 100
times without the hint of a problem, but today after partially disassembling
and reassembling it, it won’t go more than about 50 switches without
self-destructing. I think the primary issue is keeping the motor from
seperating from the base. Have to think about this...

Hi Mark,
Along with Chris, I totally agree that your design is brilliant. I tested both
versions (long and short) and both prooved to be very stable with my switch
points. At least after 200 tests. To be honest, I oil my switch points with pure
vaseline oil, as mentioned in a former message
(http://news.lugnet.com/trains/?n=21873) and this reduces very significantly
the effort needed by the motor to action the switch point. It may contribute to
the mechanical stability of your system.
Thank you Mark for this great contribution. Now all my 71427-based power unit
are build from your proposal. :-)
All the best,
Philippe.

I remember having to search all over the place when I was working on my first motorized switch! Here's the latest version of the (...) (20 years ago, 17-Dec-03, to lugnet.trains, FTX)
