Newby mechanism assembly question

I am trying to model a kind of machine screw mechanism as might be found in a workshop vice or scissor jack. I seam unable to get the 'nut' and screw to mate. This occurs if I make a simple thread or my more complex version.

Any ideas or better yet models to examine?

Thanks, Neil.

The bearing pins sit within the irregular helixes translating the vertical motion into rotation.

Any help will be really appreciated.

Thanks, Neil

PS: first day on the usenet, yes a moderator is needed.

Neil,

Did you tried using tangent and limit mates. Also you can create one surface and add a coincident mate.
