Hello all,
Here is a small review about the motorization of 9V switch points prepared
originally in French for friends from Freelug. With the help of Didier
Enjary for translation, Gaël Frazier for a final proofreading and
Jean-Louis Bergamo (webmaster of Freelug) for publication. Thank you guys
:-)

Enjoy,

Thanks very much for the comprehensive analysis, Philippe.
A compendium like yours inspires us all to build other designs, incorporate new
ideas with our existing ones, and move the whole effort forward. After reading
your reviews, my curiousity’s piqued towards another semaphore design based on
Chris Alano’s drive mechanism, with further extension of the drive lever.
Here’s a link to my latest design, which I used at our last show:
http://www.brickshelf.com/gallery/ejmcglynn/recipmotor/update-10-17-03/switch.jpg
...and the associated .mpd file:

Credit goes to Chris Alano for the drive mechanism.

Hi Ed,
This is the simplest power unit I’ve ever seen! I’ll have to build it ASAP.
Thanks a lot,
Philippe.

Ed, the .mpd file is missing a part. MLCAD tells me file X169.dat is missing!
I *think* its the rubber band you used for the design but I’m not sure. Could
it be possible for you to update the .mpd file. Thanks

Ahui -
You can find the missing x169.dat file here, thanks to Orion Pobursky:
http://news.lugnet.com/cad/dat/parts/?n=4282
If you can’t locate it, I can send it to you.
That’s the Technic 1x2 Liftarm that I use in the model’s Lever.dat subfile.
It’s a critical element, as it connects the floating, rotatable axle with the
pin attached to the peice that drives the switch mechanism...a picture would do
better here, but I’m an FTX clutz.

...dang - caught again!
Well, I just think of them as “pre-official” parts. :^)
By the way, I posted instructions here:
http://www.brickshelf.com/gallery/ejmcglynn/recipmotor/update-10-17-03/instructions/assembly01.jpg
...just modify file name assembly01.jpg through assembly35.jpg.
Folder after moderation:
http://www.brickshelf.com/cgi-bin/gallery.cgi?f=65656
I should also point out that the yellow 9v point lever part needs to be replaced
with 2496.dat, Wheel Trolley to keep the lever from slipping up and away from
the switch plate teeth during actuation.

Hi Ed,
I went on testing your proposal. It works so fine, I planned to introduce Amaury
Jacquot’s modification of Chris Alano’s mechanism you use to reduce a little bit
the footprint (expecially the width) of the power unit. You will see that
Amaury tried to put the power unit closer to the switch point for this purpose.
I try to get a block that can fit in 16 studs which is a standard inter-track
space. Actually it should fit in 12 studs, so there are 2 studs free on each
side of the track to be safe with large engines and long wagons. Here is an
evolution of your proposal with these constraints in mind. I am not completely
happy with that one because it should be reduced one stud more to fit my
expectations. Any help will be welcome.

All the best,
Philippe

Ooops, not 16 but 8, and not 12 but 4 :/ Sorry.

Phillipe -
So far so good - I need to do an actual build of your model to get a better feel
of the mechanism you’ve designed, but it looks great. There may be some
optimization left to do on it, so I’ll give it a go and let’s see what we get!
Understood about the dimensions you’re shooting for.
Thanks,
Ed
