Having some issues with Hydraulics.

Hydraulics and Sliders are acting weird. They seem to be aligned to my view (when they were placed), instead of to the object, or something.

Here’s what I’m trying to get:
I want this: http://cloud.steampowered.com/ugc/596942125447506811/5157FE177EBC92A9C6CD9468D6BF7CE582C29775/

THIS is what I’m getting again and again, with hydraulics:

The objects extend at odd angles, if I’m lucky, but most of the time I get the flying spinning collision freak out stuff does. (Though, the first thing I used them for in an different session worked fine, and I didn’t change any settings until after it was no longer working.)

And help would be appreciated.

Separate the two, then place the slider/hydraulic. as always, it’s a good idea to utilize the right-click function to place the constraint at the hitnormal of the position you selected.

Place the sliders first the place the hydrualics :I
