Well I'm buildin' a new mecha, and like usual it turned out too heavy for
the ball joints on the ankles and hips. Instead of losing weight on the moc,
I decided I wanted to make the ball joints stronger. The joint relies on the
friction between the ball socket so I had to increase the amount of friction
and pressure on the ball.
Here are two pics of my experiment...
The first is the hip joint, everything is explained in the pic:

This mod is temporary and can be done without sacraficing any parts. It only
affects the forward/backward rotation and the splay, not the outward
rotation, which has no effect on the stability.
The second shows the ankle:

Alot more complex, and alot more sturdy. The principle was to increase the
surface area on the ball and put more pressure on it too. The joint still
has the exact same degree of freedom as before, just more snug. I was truely
amazed how stong this ball is now. My mech stands great and can even do some
striking bent leg poses with ease.
Well I hope you guys can get so good mechs from these!
Oh BTW my new mech will be posted soon so stay tuned.
BTW again, the Mechastruct site had to come down :( I ran out of space on
the server. If you any of you had links to it, you might want to clear them out.
