    I have an aftermarket set (well, most of a set)that are 7/16” wide.

    Those are probably for a Logan, but will work on an SB.

    That's what I was thinking as well. If I read correctly the 3/8th SB gears are 14DP and 9/16 center hole which is why they wont work for mine.

    face thickness does not dictate the pitch....*standard* for 16DP is 1/2" but could be any thickness......bore size,key way,and pitch is what matters if looking for direct fit.

    BTW- the ones I sent a message about are in fact wrong for you junior.

    I guess I should clarify. Every time I see 3/8 thick gears for a SB they have always been 14 DP. I know that just because it's a 3/8 thickness doesn't necessarily mean that its a 14DP. It just seems to work out that way for me.

    The new 9 Junior makes chips! I bought a Craftsman 4" 4jaw chuck off of Ebay. I turned down the extra backing plate I had and drilled it for the Craftsman chuck. It fits pretty good for my first project.

    Question for those who may know. How does the wheel on the back of the tail stock get held on? It looks like there is a dowel pin for the wheel to its spindle and it looks like it takes some kind of thick c clip. By thick I'm saying 1/8th inch or better. It looks like I'm missing all of that so when I try and drill a hole, the wheel usually just comes off as the spindle gets sucked into the housing.

    Good to figure what gears you have and a thread that gear set can make, and then practice turning and measuring that thread (s) to get the feel for threading.

    Buy a loop so you can come in and pick up an existing thread, think that is shown in the book How to Run a Lath by South Bend. you can free down load that from the net or buy it for small bucks..

    Good to buy a used bunch of tool bits from ebay so you might see different tool bit designs and figure out how they were used..

    note: often you kick up a burr so a fine file or hone swipe before your last passes makes the thread easier to make/measure.
