Parts


Lots of lovely bits

Assembly


Housings with all three pins in place
Yes, that is a hole in the wrong place. There have been a few of them. Just as well this ain't brain surgery!


Springs and blocks fitted. Pin in cap fits between the two blocks.


Done.

Testing


Putting all my weight on the wheels, to simulate weight of robot, and turning wheel though the saver.
Spring tension seems just about right.
Shoe laces undone as usual...

Finished


The finished items mounted to a bit of scrap Lexan for testing.
Servo saver blocks are pegged through to the wheel support yolks beneath.
