ROTOR HEAD

 
 
 
 
 
 
 
 
This head was built from original drawings of the Bensen B8 Offset Gimbal head, I have added bearings and trunnions to the lateral and longditudal forks in a similar style to the teeter forks, rather than have the bolts bearing directly onto the aluminium.
This involved some changes to the shape of both sets of forks but still retaining the key dimensions of the Bensen head.
Making the head is not a difficult task if you have the machines and skill to use them, but it is time consuming because each set-up is only for one or two components, it would be true to say that you will spend far more time setting than machining and scrapping a part will add even more set-up time.
Add to this the problems of getting the correct materials in small quantities at reasonable cost and you can see that unless you enjoy working your machines, building a head makes no sense ,IT IS FAR MORE COST EFFECTIVE TO BUY A COMMERCIALLY BUILT ITEM.

But if you still fancy hours of frustration and turning good metal into swarf, drawings for the ORIGINAL Bensen B8 Offset Gimbal Head can be downloaded from the Drawings page,they are in a ZIP file in AWD format and can be viewed in IMAGING.  Drawings of the modifications I have made can be seen HERE.
 

 
The top part is exactly as the Bensen drawings, as is the torque bar.
The shape on the longditudal forks is clearly different but does have the bonus of only needing one set-up to machine both angles on the top, the same applies to the lateral forks.
This rather poor quality picture shows 
(a)   My inability to handle a   foolproof camera
(b)   Teeter trunnions
(c)   Teeter Forks
(c)   Teeter block
The hole in the centre of the block is used for aligning the assembly on the bearing block
