If I would not have been so impatient when I built the arm, I would not have had to do it over. I hot melt glued the arm together instead of silicone. And sometimes servos get hot. It melted the glue and Bang!! The whole gripper came apart. Not only that when I touched the servo, the hot melt glue that was melted got on my hand and burn a water blister into my finger!
Before applying, scuff the area on the servo that you will glue for a better stick. The servos are a very smooth surface and that's not good for glues. Also wipe the area with rubbing alcohol and let dry before glueing. I find that helps.
Btw I noticed this comment posted by Hobbytronics on that servo.

For those of you having problems with these running hot and drawing excess current, it seems to be because you are trying to drive them beyond the mechanical end stops.
If you are driving these servos using the Arduino servo library (or your own microcontroller code), then the high value of 180 (Arduino), which creates a 2.4ms pulse width, may be too high and tries to drive the servo past its mechanical end stop. This leads to a high current being drawn (1A+) and the servo gets hot.
If you reduce the Arduino Sketch value from 180 down to 170 (or drop your pulse width down to 2.3ms max) then you should be ok.
In normal operation (no load), these servos only need about 50mA when moving and virtually nothing when stationary.
It seems that the setting of the mechanical end stop varies somewhat.

I always put them 10 and 90 except in one case I needed to go to 5. But that is rare.
Spark Fun calls it the 10333. If this is the same specs, I would like to order.But, I have tried so many and was the wrong size. Do you think that the specs match?
