IThe way I have this put together, the Morse taper and mandrel with capture slot is turned out of D-2 and captured with a 1"x0.500 bronze sleeve which has been split and subsequently lapped to fit within the pressed-in bronze bushing in the 316 stainless die holder. The knurled aluminum handle/clutch control is attached to the holder and applies pressure on the clutch sleeve within via a radiused 1/2" O-1 rod which was single pointed to 1/2 28 (as I happened to have an oddball tap lying around)
I was a little worried about it, as the clutch, while very smooth, will allow one to overcome any rotational force I've been able to apply. Fortunately, the thing is robust enough that it will stall my lathe, even in backgear,well before it gets anywhere close to bending anything.
I had initially thought that I would always hold the handle and modulate the rotation, but the aluminum handle is nice to my ways, and I find that I often just lock down the clutch and let it rest when cutting.
I generally just leave the tailstock loose to allow the die to advance.
It hasn't been issue if I start with an appropriate od on the part to be threaded, but, if needed, one can lock the tailstock and push with the feed until the die catches as well.
If you get slow on the feed, the taper just pulls out of the tail stock and you feel shame...

I used my LMS 3990 mill (I know, Chinese junk that can't be mentioned) to make a dial indicator clamp for my 10k. This was my first time ever making anything with a mill. Initially, I drill the hole to 3/8" for the large end of the indicator and promptly realized it should not be held by that end. Rather than start over I made a bushing with 1/2" brass rod held in place with a little set screw since I busted my OD when turning on the lathe. All in all, though, I couldn't be happier with my first attempt at machining.
I angled the far edge so that I can slide it over the v-way and be kept out of the way over the gear box.

What about replacement Crossfeed screws? Has anyone tried making one of those on the lathe itself? I know, I know, I've got noob fever- I'm just curious. Seems like you could get a piece of appropriately sized prefab thread and go from there.

I have done the large dial mod on (2) 9" lathes so far and they require modifying the cross feed screw, I replaced the acme thread part on one of them and lock tired and cross pinned the new acme thread.
the large dial conversion is a very nice addition to these machines and very worthwhile.

Router holder for SB 9c
Very simple router motor holder for my 9c.
1/4" Aluminum plate with wooden blocks to fit the motor. Had to angle the motor to get to the center-line of this project, but most of the time I would have a second block beneath the front of the motor.
