After this Jim went around different machines each with different functions, such as sanding or drilling, and showed us how to use them effectively and safely. We were then instructed to make a simple jigsaw piece using the equipment we'd just been shown. I found this a scary (as I'm very clumsy and constantly worried I might stab myself), but really fun exercise that tested how well we'd listened to Jim and got us used to the feeling of working the machines. The whole process reminded me of high school technology class, where I'd used similar machinery before, but not for use on sets.
