    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.

      Just remember to tilt at the helix angle of the threads on the leadscrew.

        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...

            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.

              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.

                Yeah, that is why I don't visit any more, as a hobbiest that site is not for the weak hearted and you have to be a rocket scientist to comment or you need to just stay quiet.

                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.

                  Posting online is just weird for me, both here and at PM. You see, I do metal work and MRO for a living. But its also a hobby. My whole life. So I kinda don't fit anywhere, just fall through the cracks.

                    Nah.. You manage to fit in both worlds without problems.
                    At the end of the project, there is a profound difference between spare parts and extra parts.

                      I found a Boxford threading indicator on the ebay UK site, as the lathe is based on the SB9 it will be similar. Like the SB prices, this is extortionate, but what is interesting is the close up of the gear teeth and the wear of them in spite of the longitudinal slot in the leadscrew. The tooth style looks like an ordinary spur gear.

                        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

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

                            I had mentioned tilting the gear for cutting, I should also mention, I believe it should be plunge cut, so teeth are curved to fit screw with more contact.. could be wrong , but it won't wear fast.

                              It will be fun making one for ten cents on the dollar, eh?
