Ezio's Hidden blade
So I'm making a dual action hidden blade for my husband's costume. I'm using plastic styrene and it's working fairly well, but I am running into a few problems.
So far I've got it shooting out all the way about 20 times in a row before it decides to hate me again, but It only moves back in about an inch unless gravity is helping it. I keep thinking it's a friction problem, but it doesn't make sense that friction is a problem for retracting but not ejecting.
The other problem comes with the infamous wheel mechanism. It hates me. This thing works great without the wheel (again, only the ejecting half), but add it and suddenly it doesn't really work. But that's the only mech that I've found that works with dual action.
This was my husband's (unfinished) Christmas present with the promise of having it ready for Comic Con (that's in one week). SO any suggestions or tips for either of these problems would be great.
