cPro motor fastening tools cPRO fasteningtools motor mounting By Nathan Lederman on 10/24/19, 9:13 AM • 705 views Hey guys, I want to put my motor higher as the CAM and LBUS cables are just above the ground. I don’t always have the possibility to use Arri locking pins nor do I always have 1 9mm bars on the camera. What do you guys do to make sure there comes no pressure on the motor connectors when someone let’s the camera rest on their leg or on the ground? Dogbone, Jerry Hill bracket, Cubebar by Ratworks, angled cables... Kind Regards, Nathan
I don’t always have the opportunity to have a rod mounted on the topside of the camera unfortunately.

I just found it to be important that the 19mm-15mm reduction insert in this bracket is oriented exactly like in this product photo (the opening of the insert lined up with the opening of the clamp), because else the whole bracket can rotate on the rod when there is too much force on the motor.
Vince On 10/24/19, 10:13 AM Hi Nathan First of all, congratulations with your new cPro hand-unit :-) Not sure what you mean with Arri locking pins? The one from the tophandle? I usually use the 15mm rods on TOP of the camera for mounting motors on the camera. If that doesn't work because of lack of space, I use an offset/dogbone adaptor on the lower 15 or 19mm rods or the 19mm bar from Ratworks. What's also nice are the accessories from Rowa Mechanik. Angled cables are nice, but as the bottom part of the motor is still lower than the cables you'll may have problems with that. All the best
Hey Vince, thanks! I mean anti rotating pins. What offset bracket do you use?

The antenna points straight into the ground which doesn’t help - I have an adapter I use with my PAM brackets to reorient the antenna upwards, but it’s a little messy to have an extra cable. I find the best practices are the mount the motor on the bottom via 15mm rods, and the. Put the handles or your handheld setup on 19mm rods - this stops the motor connectors from every touching the ground, and also keeps your motors and handles on different sets of rods (which for me, is a must).
Gunnar Mortensen On 10/29/19, 7:45 PM Nathan there are so many different ways to do so. I have a variety of motor mounts. I am a big fan of the hill brackets that offer a good level of versatility. The trick is to separate your motors from anything the operator touches. They can’t be trusted 😜 a lot of the time I will rework the motors to keep it as streamlined as possible. It is great to use a fat gear to compensate for any lens variance. It is easier to keep the motor in one position and make up any gaps.
