In an effort to conserve fuel, I disassembled my power suit shortly after the opening mission at the museum and stored it in my inventory. Upon returning to the red rocket truck stop, I tried to reassemble the power armor in the armor station but wasn't able to figure it out. I transferred the pieces but it seems to just store them in the vault. I tried to equip them but that wouldn't work. I tried dropping them into the station but they just fell randomly on the floor. Am I doing something wrong or is this a bug?

you only took the PA's outer armor you need the PA's skeleton next to station to repair the parts.

Ah, yes, you are right.. I'm surprised I left the frame behind. When I disassembled I didn't see a standing frame but when I went back to the museum there it was. Thanks!
