More beer, more beer!!

A cry from my past.

 As I said, I did check whether the drive would be affected if I cut down the depth of servo on the outside of the hub. It doesn't, so that's the way I have assembled them .As you will see in the first picture, it makes the servo almost a flush fit with the 5 mm thick disc. A certain amount of jiggling is required to make sure that the body of the servo is on the same level as the disc but it's well worth that extra effort.

This shows just how much of the servo is now on the inside of the hub as compared to the usual mounting method. The servo itself is very stable and doesn't move at all even under pressure but the wheel will always be very slightly wobbly as it will never be a perfect fit due to the the fact that its not designed to be. Since this Trundle is only intended to be a full size test bed for the software, this isn't a serious problem. The servos will provide enough motive force to move the robot but not very quickly. In a test situation, this is a better set up than running at full speed.

The white adaptor piece (from the servo kit of parts) was first stuck to the hub and then screwed through into it in order to be as secure as possible. The screws used are M2 x 2 mm and should really be longer. The holes were drilled with a pillar mounted drill press to make certain that the holes were vertical and the tiny drill bit didn't break.
