I hate to start a new thread for something so basic, but I searched and could not find a decent aluminum servo horn for Futaba spines. There's a huge one at ServoCity (http://servocity.com/html/servo_hub.html),
but is there an equivalent to the Trossen/Lynxmotion Hitec horn? (http://www.trossenrobotics.com/store/p/5509-Hitec-Spline-Metal-Servo-Horn-Tapped-.aspx) It has a nice thickness and weight.

Or even better, is there a tool available for pressing in your own splines?? Then we could make any kind of horn we want.

The Lynxmotion one that we sell here is for Hitec splines only unfortunately. Couldn't give you a good recommendation for one that is a Futaba spline, and they're generally expensive (aside from the Lynx ones).

Question:

Do the aluminum horns really make that much of a difference vs plastic? Are they to make the bot stiffer, or just to prevent breakage at higher torques?

Yes, yes, and yes. :)
I've had plastic horns break right at the splines before (admittedly in combat robots) so I figured if I could find metal ones cheap enough it could save me any possible future headaches. I actually have metal single arms but I wanted at least two arms to make mounting easier. The ones I found have four.
