I have just bought another Leitz table tripod. It has a type D ball head. My older version has a type B ball head. On my older one to change from a ⅜" thread to a ¼" thread, you just unscrew the top knurled sleeve and reverse the disc underneath, which has a ⅜" male thread in the middle of the disc on one side and a ¼" male thread in the middle of the disc on the other side, then screw the knurled sleeve back on, which firmly locks the disc in place. The disc has a notch in the side, which locates on a lug to prevent it turning. 

 

For reasons best known to them, Leitz has changed this simple and effective method to something else. On the picture below, the sleeve marked Part A screws onto the main shaft of Part B just above the cross bar. A ¼" threaded spigot then passes through a loose ⅜" threaded adaptor, Part C, inside the main sleeve, Part A (you can see it poking out of the bottom of Part A). The adapter is prevented from turning within Part A by means of a steel key. I feel that the ⅜" adapter should be able to be turned when pushed down into the body of part A, so that just the ¼" threaded spigot appears above the platform on which the camera sits. 

 

Has anyone any experience of these Type D ball heads and am I trying to make it do something it cannot do. I feel given that they have made both a ¼" and ⅜" threaded parts, it must be designed to be alterable.

Doesn't mounting a camera with a ¼" thread socket simply push the ⅜" threaded part into its sleeve?

 

I don't own this head, but I've read about it somewhere, possibly here in this forum.

Can you open the base of the ball head?

Wilson,

 

Just try to screw in one of your camera with 3/8" female thread, it would be secured.

 

Unmount the 3/8" camera.

Then try to mount one of your camera with 1/4" female thread, when screwing in the outer part will retract inside.

Second version of genius Leitz ball head,

;)

your 1/4" camera would be secured with the 3/8" size with 1/4" size inside.

 

 

I think that you wanted 14121, one with reversible threads like this :

The 3/8" adapter should have just pushed down out of the way to reveal the 1/4" screw but didn't. There was a small amount of surface rust on the steel key inside sleeve A, that was jamming the adapter in the up position. Once I had scraped the small amount of surface rust off, and applied the miracle cure-every-ill of WD40, all worked as it should. Many thanks for the help folks. I now have one of each type of ball head, working properly.
