I picked this neat looking hone set up at a flea market a few years ago. It looks pretty old. It promptly dissapeared into that black hole that lurks in a lot of our workshops. It suddenly reappeared yesterday. Darn, I could have used this a couple months ago after I bored the 3/4" cylinder on a model engine I'm building.

I started to assemble the adjuster end and am a little confused. Something isn't quite right. I think I know the key, but I'm hoping may maybe one of you guys might have one and can confirm my thinking as well as maybe commenting on it's ability as a hone set. I've never seen one and would like to try it but I also feel that if it was a good design I might have seen one by now.
This is the assembly diagram:

And this is a closer picture of the adjuster setup:

I think the ball shaped piece on the close picture, which is not shown on the assembly sheet, should be between 5 and 6, and pressed into part 6 (the speed sleeve.) Number 5 (front cone) is not threaded and needs the threaded ball piece to make the sleeve push on it to expand the mandrel. The speed sleeve has no other threads, except for the micrometer collar 7, which is a pressed in assembly and threads the stop screw. The stop screw moves in or out by turning the micrometer collar. I'm not at all sure about the retaining nut 8, it may be that it's part of the micrometer collar assy.
Also confused about the internally threaded cap, shown just under the ball piece. It has a screwdriver slot on the other end and also fits the thread on the shank. Maybe for the stop screw to ride on?
I would also like to know if the sandpaper "abrasives" are available, althjough I really think I'm dreaming. They are custom fit to the mandrels. A thin piece of sheet metal is bent over the edges of the sandpaper abrasive and the assembly slides onto the mandrels from the ends. Probably a difficult thing to make.
Opinions, answers and comments welcome.

Just thought I'd add this part of the instruction sheet.
