PAM Kit (Preston Adj. Mount)

By Leave a Comment 0

P.A.M. – (Preston Adjustable Mount) Lighter, Better, Stronger, Easier, More Options, Cost Less! The PAM mount allows owners of Preston motors to simplify operation. The new PAM Mount takes advantage of the design of the motor and uses it to the operators benefit. As there is a hole that goes all the way through the motor (the mounting rod), a rosette is secured in the place of the rod. This allows the motor to be used on either side without going through the difficulty of changing the bracket setup. The PAM mount keeps the motor at a right angle to the lens at all times. PAM is positive locking, every 10 degrees to the lens over 360 degrees. The mount is also adjustable vertically relative to the lens by 5″ inches. Attaches to any standard iris rods. PAM is very quick and easy to use. The motor mount can stay built even when not in use. And best of all, the PAM Mount weighs just 3.4 ounces. (This is less than Preston’s current swing arm.) All PAM Mounts are hard anodized black.

In Stock!

Tech Note: 15mm is not 1/2″. If you try and use the 15mm arm on a 1/2″ iris rod it will not work! 15mm is .590″ decimal , 1/2″ is .500″ decimal.

Tech Note: If the lock down screw seems to stop, like it bottoms out. The cause maybe galling, (Adhesion friction) Try a drop of lubrication under the washer.

If the Pam arm seems loose, double check to make sue the iris rod is tight at the camera.

Personal experience: When calibrating the the lens motors, I would hold the motor to the lens when they come to the lens end stops. The motors are so strong they will try and crawl off the gears. Once the end points are set, the motors will not try and crawl off.

PAM Offset

By Leave a Comment 0

The PAM Offset allows the motor to be offset by one or two inches depending on which way you position the motor. This replaces the arm clamp with a new clamp that has a one-inch standoff between the motor and the support arm. This allows you to get the motor into the Iris gear and around corners. This PAM Offset combined with the width of the motor will give you two inches offset. Takes seconds to install and requires no tools.
