>>9808855Parts connect fine. As
>>9809254 says, the hammer head and handle are locked together with a Technic axle pin.
>>9810241Close enough. When you buy one of these brick separators, they come with a transparent axle pin, a spare one. At first, that's all I thought it was. The problem I was hinting at is the axle pin holding the two parts together is flush with the parts. There's no pushing the pin out with a fingertip, and transparent plastic rubbing against transparent plastic means the fit is incredibly tight. So if you want to access the plate lifter, you have to use another axle pin to push out the axle pin in the separator far enough for you to pull it out with your fingers. Or you could use another brick separator to push it out, but why not just use the other brick separator at that point?
