The tooth style looks like an ordinary spur gear.

    Just two days ago, somebody listed new, never used thread indicator still with the factory packaging. Bidding was starting at $250

    Lately I been browsing through Clausing manuals, likely going to buy a Clausing.
    But, one of those books showed a Clausing mill attachment.
    It is setup similar to what MrPete222 did (or he copied Clausing) such that there is no overhang, the vise (clamp) is directly over and centered over the saddle crosslide

    this one is for a Clausing 59xx series, 12". perhaps a viable option if found on the used market

    Nah.. You manage to fit in both worlds without problems.

    Thought I'd share a SB original milling attachment that I got with my SB9A. I completely redid mine for looks only as the mechanics were all good. The funny thing is I have never used this as I have a BP clone, but I can't seem to let this go I feel I need to keep it together as a set so here it sits still in it's original box too.

    Hey, thanks for the pics! So that confirms that mine isn't really a SB attachment. And now I know what the SB part looks like.

    Yeah, I got no idea why. They have an entire forum for them. I think its just pretty arbitrary and its just whatever they feel like at the moment. Even the president of Grizzly has a login there, but he doesn't post often. I've ran across him before, nice guy.
    He doesn't post because the SB guys and other ripped him a new arsewhole for selling a rebadged Asian lathe as the "new" SouthBend.

    Regarding that missing threading dial indicator, the Atlas we are doing up is missing its own, and I bought a Mod 1 x 16 teeth spur gear as a start in making the threading dial for the lathe. The tooth pitch of the metric gear is similar to the 8tpi pitch of the leadscrew. With the axis of the gear tilted to the helix angle of the leadscrew, it will work as there is no power transmitted through them. The Atlas uses 16 teeth and four marks on the indicator, if your SB should have a 32 teeth gear, it would probably have 8 marks.
    If I come across any more of those old threading tools, I will save them for you.

    After seeing the price on those taps, I figured I better find another way. Bummer, because there was 3x more of those taps just a couple months ago...

    I actually could index off the tumbler reverse gears, they're 32 teeth but 20 pitch. And then just stick a dremel in the toolpost. Figure that'll get me in the ballpark anyway.

    Another way would be to get a 3/4-8 acme tap off eBay, and then use that to free-hob a blank.

Screw above gear is pointy and used as the indexer. Looks scary, but I have used it with mill, and before that with a shaper, and it works. Yours would be sturdier, since it does not need to stick up like that. The brass looking thing under the gears is a split cotter to hold the shaft. Next pic is all the parts, including a couple of mandrels for holding the gears.

    I would *love* to do that... in fact I've already got my steel picked out. Right now I'm just getting to know it with a simple job -- making a new long-nose live center. I haven't even done any accuracy tests yet, doesn't seem to need them. Of course I'm not using the dials at all, just measuring. (the dials are kinda crappy)

    SB sold a gear cutting attachment, basically a simple indexer using change type gears, that was held in the milling attachment, I believe. I saw a pic in an old Audels book from 1940..
