In getting the shape as well as size of place where your present driver fits, it is a good plan to oil the inside surface of the hole in driver (in which the spindle fits) and fill it with plaster, then take out and send the cast by express. The shape of cock-head may be got by similar process.

We will send necessary instructions, so that any one of medium skill can put them in at the mill.
