well i want to set proper constraints for a character holding an axe with 2 hands..... he has iks in both arms and i want him to grasp the handle of the axe and not let go but still have the freedom of being able to move the hand up and down the shaft. can anyone show me how to do this? thanks user added image

I believe you could constraign just ONE hand to the handle of the axe, and just key the other hand, so as to give you a little freedom regarding the "shaft-slide".

Not sure if it will work for you tho, but it was just an idea user added image

keying the hand would be far too difficult... i want the axe to be the controller for both arms so i don't need to rotate bones.

You could use point and orient constraints to "stick" the hands on the axe handle. Place 2 locators on the axe handle where the hands should be. Parent the locators to the axe. Then, create 2 additional locators and parent each hand to one of them. Apply point and orient constraints from the hand locators and their respective axe locators. The hand locators will follow the axe locators whenever you move the axe itself, but the hands can still move around as needed. Grossly simplified here, but that's the general idea.

i already got that part down... but the same problem is still there.... i want the hands to stay on the shaft and not move off when i move the locators around.... i just want it to slide up and down.... the sick minded ppl must be enjoying this :p

edit: i figured it out user added image
