Step 11 Mounting the second servo.

 This part is very simple, just glue your servo to the OUTSIDE of one of your wooden blocks, but make sure you glue it on the same side of the trolley, as the first servo, you will need them on the same side, you dont want to get to much weight on the end of the trolley that is un-assisted, also it makes the wiring easier.

    I high lighted the pictures below, showing were the servo should go, one thing to keep in mind, you want the front of the wheel on the servo, to be lined up with the guide rails on your trolley.  On the other end of your trolley, you will need another pully, I took mine, and my belt out of an old printer, you want the pully to be mounted were the front edge is lined up with your guide rails, also take into account, the over al length of your belt, if you did step 5 correctly, you should not have any problems here. So once you have measured out and found the right place for your pully, go ahead and get it mounted, i drilled one hole in my plywood, and put the shaft with my pully on it, into the hole, and just blobbed some hot glue under the pully, so it couldent fall down to the plywood base on the trolley.
