Gorelock 2, New Style

By Leave a Comment 0

(GAD 2) (Pictured, This is just the Fork, no DR)

The GAD1 and the GAD2 forks have the same features. If you have a Pro sled with a 1.500″ post size and think you will be upgrading to a 2″ post in the future, I would suggest buying the GAD2. That way you will only need to purchase a different size docking ring.  The O.D. of all the rings are the same size. Be sure and double check the size for low mode placement. The GAD2 accommodates the all the post sizes. As before the same great features are still inter-graded. The key features are, no aircraft pin, automatically locks the sled in place, securely holds the sled from flopping from side to side when changing magazines or lenses, the docking ring can be positioned right under the top stage, the post never touches the fork when docking, the Gorelock1 & 2 has a built in 2 degree angle, the sled can be rotated in the fork for adjustments, Blue release levers are on both sides for ambidextrous operation, two handed control on the sled when mounting and dismounting. The new features are; now accepts the largest to smallest post size, starting with the MK-V  4 stage post size of 2.125″, 2.00″, 1.860″, 1.800″, 1.790″, 1.750″, 1.750DS, 1.685″, 1.580″, 1.500″, 1.500DS, 1.495″, 1.477″. The O.D. of all the rings are the same size.

Now sold with Blue Levers. Call if you do not see your post size listed.

Betz Iris Rod Mt. – MDR3 Mt. – QR Mount

By Leave a Comment 0

MDR3 Mount bracket (Revised) to interface with the Betz Top Stage (60mm) Iris rod  Mount. This  mount slides onto the Betz or Pro top stage Iris rods.

The 60mm rod spacing is also the same spacing as the Arri Alexa. You will need to add the MDR3 Mt. to interface with this part. The Popper will also work with this part.

The MDR3 bracket mounts to the MDR3 box on top or bottom. Two screws mount from the side in the right-side up position. The Iris rod mount attaches to it in the center of the box.(4 Screws)  The box can be positioned every 90 degrees for what ever cable position you prefer. In the upside down position two screws mount from the side and two on the bottom side.

The MDR box can still be positioned every 90 degrees for cable placement, the box labeling will be upside down. (Shown in pictures)

If you need a quick release, the Popper can be sandwiched in between the two brackets. (shown in pictures)

Anodized black comes with screws!

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.

MDR 2 & 3 Mount

By Leave a Comment 0

This is a new mount system for interfacing your Preston MDR 2 & 3 to the GPI Pro Donkey box 2 & 3. This new design will allow the operator to position the MDR box at 90 degree positions. This will allow your lens and power cables to come out the side of the lens if needed. Adjustment forward and aft for clearance of your cables. The other benefit to this design is its simple and quick MDR removal to go to A or B camera. Or if you are an operator that has two sleds one set-up for low mode and one for regular operating, swapping over is simple. The best part of all the Quick release mount that attaches into the Arriflex 3/8-16” screw pattern on the camera bodies. The MDR box will be able to be clocked on the camera to your desired position as well.

Note: There is a mounting difference between the Donkey Box 2 and Donkey Box  3. The DB2 mounts with two 6/32, 2″ spread. The DB3 is three 6/32 in a V- pattern. Please double check what you own!

Hill 2-N-1 Motor Mount

By Leave a Comment 0

This is a motor rod for Arri cameras. It looks like a lollipop and screws into the rosette where the handle would go. The mating side of the Hill 2-N-1 is made of nylon so it conforms the rosette and will not move. The name 2-N-1 means that it has two uses. The mount can be taken apart so you have a square to round rod that will slip into the square access hole on the Arri BL’s and the Arri 35-III handle.

By Leave a Comment 0

The double D shaft can be swapped out for shorter or longer shafts. Comes standard with a 3 3/4″ shaft length that will give you 4 3/4″ overall length.

I do have some dedicated size arms left over from a special order. These are 15mm & 19mm arms. They only will work with that size iris rod. They are laser etched for the size they are dedicated too. They will not fit three sizes of iris rods just the one size! While supplies last! Will not be made again. Anodized “Black”
