    I assume that your machine has a metric gearing chart inside the end cover, ours has.

In reality, there are only two that I think ever got used, inspite of making a lot of foreign car parts, and other metric stuff, on the machine.

    Hello Herb,

    I would appreciate your sharing any info you have on those metric QC gears that you made for your 1307. I own the 1307 that Petras mentioned (which came from PA) and I would like to acquire the gearing for metric thread cutting. Here's a picture of that chart you are mentioning.

    Thanks, Alex.

    Default Metric change gears for South Bend 1307

    Alex,

    It does not look like my father is going to reply to this, so I'll post a picture. It is just a splined hub and gears with two small screws to hold it against a shoulder. All made in aluminum for expediency and the fact that we did not expect to cut a lot of metric threads. Very simple construction, as you can see. I did not look at the chart inside the cover to see if all the optional gears were made, but did make the following:

    #160077 59T
    #160072 55T
    #160067 51T
    #160062 47T


    As you will note, also stamped the SB part numbers on the gears for convenience when using the chart to figure out the correct thread.

    Default 1307 again Sidney this time

    Been reading this thread and enjoying it as I have a Sidney 1307 It obviously is the earliest version of the 1307, mine interestingly enough is serial number 13070001 So I have to wonder is it very first and is it the actual one in the operators manual picture. The manual is almost hand made like a prototype
