Metric PTFE tubing was used to produce a ventriloquist mask.
How to ensure a nice smooth jaw action on the increasingly popular ventriloquist masks.
PTFE tube was used to make a simple bearing within the mechanism to control the jaw action, as well as in the hand held controller.
PTFE has a very lubricious surface and so, is super slippery, which enables the cables to move freely within the mechanism, ensuring a smooth and natural (as can be, when wearing a comedy mask!) movement action.
Maybe we'll see the mask in action on 'Live at the Apollo'!
