Thanks for the info! I realized upon further inspection of your pictures that the smaller rod of the actuator actually goes through the top of the actuator block. I was wondering if this is the only way. To illustrate my point, here are some pictures of the MG God Gundam I'm working on.
Actuator 1 Actuator 2 Actuator 3 Actuator 4 The first two pictures are of the leg in the fully upright position while the last two are when the leg is fully bent (in like a kneeling position). As you can see, the top block actually moves along a groove and only the bottom part is actually fixed. Is there any wat to still do the modification so that the metal cylinders will be able to move AND pull the top block along. Currently, the metal rods that I'm using are from nails that I sawed to length and filed down. They somehow managed to work (they pull the top block down) even though they are not fixed on the top block. I was hoping to find a better method so that I could have full functioning actuators and have them look cool.
Sorry for the thread hi-jack...
