I was wondering if anyone knew where I could find the specifications for making a collet draw bar for a 13 lathe? I checked the downloads but didn't see anything. I keep scouring ebay thinking one may pop up at somepoint but honestly may just try and make one if I knew the dimensions, etc.. Also, let me know if anyone's got one they are looking to sell. Thanks

South Bend 13 Drawbar 5C Collet Adapter Thread Protector | eBay
<p>South Bend 13 Drawbar 5C Collet Adapter Thread Protector. There are 11 collets that are included with this setup. This may work on other south bend larger lathes. Please be sure this is the item you want before purchasing because it is sold as is with no return. </p>

By the way, the 13 takes 5C collets (unlike the older 14-1/2), which have threads of 1.238x20. You'll need the adapter for the inside of the spindle, and the thread protector as a means of pushing off the adapter.
Also, the spec sheet provided here will provide other details of dimensions for the spindle:
(Edit: It also depends on the size of the spindle on the lathe--the 13 early lathes used 2C collets of maximum 11/16" size, while later ones had a larger through bore and used 5C collets up to an inch. The drawbar for the older one will be more difficult to find, probably, and so will the collets. I speak as one who has pieced together a minimal set of 4C collets for much more than getting the whole set of cheapie import 5C collets.)

I saw that one on Ebay too. Is that about the going rate for a drawbar for a 13? I wasn't sure what the typical price was for one so wasn't sure how to price one. That said, I guess I'll what I need to to get one. It did look like a complete set-up for that price
I haven't seen enough to know the going rate. But I paid $400 for a 4C drawbar for my 14-1/2, including the bar and the collet spindle adapter (but not the thread protector), or any collets. But the 14-1/2 is much less common and I wondered if I'd ever see another one for sale. Even then, the seller didn't know what it was for, and I had to know the dimensions to be pretty sure it was the right one, though fitting 4C collets was pretty indicative.
But I imagine I'll be doing a good bit of work with the collets, given that I intend to so some light milling with the lathe (I have the milling attachment for a SB 16 that I will adapt as an early project).

You're really going to want a drawbar collet setup. You will use collets a lot.
I've never bought a drawbar. I imagine it is something they sell if there is a demand. But in my world, a drawbar is a perfect first project on a new-to-you lathe. You get to cut a tapered bushing, internal threads, and.. Well, there's not much to drawbars, that's the reason why they're not storebought.

I went simple, bought 2 sets of MT2 collets (metric and imperial) that had a m12 thread, and made my own draw bar from a section of 12mm allthread, added a plug turned to fit in the spindle, and a nut on the end, works lovely. the MT2 fits straight into the spindle bore on my 1919 13".

Don't scare off the new guy. If a 7th grader can build a birdhouse, a new lathe owner can turn up a drawbar. It combines the skills of turning/profiling, threading, and fitment of standard parts (a bearing). Perfect way to get one's toes wet on day one.
