‘Baby’ version, making the biting action faster
In a previous post (‘Baby’ one: new drive system) a new head/neck drive mechanism was introduced based on a crank wheel design along with a slip-clutch.
This can be seen in action below…..
This was a lot slower than the original worm-and-wheel drive (which had to be abandoned as it chewed up the gears).
The crank wheel and associated parts were removed.
The 200:1 motor and gearbox was removed and replaced with a 120:1 version.
The following video shows the result.
As you can see this is slightly better than the video at the start.
