Re: 9A lever collet closer - spindle pin


I got both model 9A and 10K
I had to rebuild the 9A because it was missing many components.
Both work fine. You get a much tighter hold with the hand lever closer than the standard closer
the main component I rebuilt is the part that fits on the spindle. I made it off 4340 steel

I have a 10k closer I have had issues with the balls in the inside 
If I take apart and set the balls in the race it works good when I change the collet I have to take it apart again and reset the balls and race. I think the race on mine is worn out this is what lock/pulls collet in place when you activate the lever. 
I am also missing the pin on the spindle also but the closer never moves out of index 
10 k doesn’t use a nose piece as it is 6k collets with pin in end of spindle

My 9A came with a collet closer, I believe it’s the factory unit not aftermarket. I think it’s complete based on what literature I can find which does not include any specific instructions for this item. When milking using the SB milling adapter the mill repeatedly comes loose in the collet even with the collet cleaned out.
Looking into it closer I found that on the far left end of the spindle there is a 1/4” hole through one wall which had a sheared-off pin in it. I punched out the remains of the pin. Seeing the empty slot in the right side of the collet closer assembly that seems to do nothing I made a pin 1/4” OD to fit the spindle hole then 3/16” to fit the slot in the closer. This pin is shown with the red pointer in the photo. The fit in the slot is pretty tight. Adding the pin doesn’t seem to make any difference to the collet’s ability to hold the mill.
Do any of you know if I have this assembled correctly with all parts?
Should I have made that pin? Is it supposed to exist in this assembly? Some 9A’s don’t seep to even have the 1/4” hole.
does anyone have an actual install/operation sheet for this assembly?
Thanks in advance for your help!
