You're right, we are planning on modifying a few things to make the mechanism more "nice" to the P60's, though we don't feel that a full on redesign is necessary. There's already quite a bit of surgical tubing on the arm, and we plan on adding a bit more when we get our next McMaster-Carr order. We're also considering swapping out the drive sprocket to a 10 tooth which should make the transmissions see about 33% less torque during operation - not to mention that the arm should slow down a bit too.

I'm also going to look into the modification that Swampdude suggested and see if we're able to do it in our shop.
