The setscrew is on the rest side of the colletrack.

Webb,

With the tray facing forward on the tube, the screw holes are at 0 degrees, or at the back of the spud.

From the bottom edge of the spud rear, the first hole center is 0.250 and the second is 1.000, not much room

on the lower hole, I only have about 0.125 space from the hole to the edge, you might use .300 to be safe.

My socket head cap screws may not be original and they may have been little square head screws, but I used

1/4-20, 3/8 length. 3/16 drive size, they work well, and easier to adjust or remove.

Hi There,

Steve, I think I'm good.  I've got most of an old collet rack already.





The only things I was missing was the actual rack and the hook to hang the
draw tube.   I got a hook as well from Fred.  The shaft was quite a bit oversized
and I had to machine it down.







The tube is there and I think it is the correct length.  The diameter of the pipe is
.672"  which is basically 43/64".





The one thing I don't know is the location (or the size) of the set screws used to
lock the rack to the tube.

If you or someone could provide that info, that would be very helpful.

Thanks for the help so far!

I worked for a short time as a special education teacher, and I taught my students to talk themselves through difficult tasks they needed to remember. Subvocalize if possible, better out loud than not at all. It gives your brain more ways to process, which helps in many ways. 

I always told them that talking to yourself is only a problem if you get in an argument with yourself, and lose. ;)

SWMBO laughs at me, but it helps. And I've noticed she does it now, too. Though I never say anything about. If I still want live. :)

Re: Which do I keep? 1949 9" Tool Room or 1935 9" Heavy

Stuart Wilby
 

Have a good retirement Vince, I bought my SB 9” a few years before retiring along with some accessories, it soon became clear to me that one machine was perfect for my hobbies, motorcycle repair and general machining on a small scale, however, it became clearer by the day after I retired that one lathe was not enough, so I bought another Lathe and built a dedicated space to work in and keep it all together, the lathe had a milling slide which has its uses alongside the milling machine, my advice would be to keep both machines if you have the space just because you can, they take some finding these days, have a good think before selling and I’ll guarantee this, if you sell one, inside a week you’ll regret it when that need appears at your workshop door.

replacement for compound slide

Saw a video where the author eliminated chatter on his PM lathe by replacing the compound with a block of metal.
Can anyone provide info on doing this for a SB 9A?

Re: Lever retractable threading tool

Ondrej Krejci
 

Greetings,

To elaborate on why instantaneous reversing is needed, to get the intended use from this clapper style threading tool the split nut should stay engaged and no pulling out of the tool should be required, and the the carriage is unwound back to the starting position.  Without some kind of instantaneaous reversing, some good timing for coasting till the motor can be reversed or stops will be necessary.  Just switching to reverse with a regular single phase induction motor running at full to 75% speed will keep it running forward.  One can also use a piece of wood to brake against the chuck or face plate, but that is tedious from personal experience.

Enjoy,


OK

Greetings,

The flip up threading tool holder is interesting, like the clapper on a shaper.  Unfortunately, the lathe needs instantaneous reversing:  three phase motor, clutch drive, special single phase motor or excellent operator timing.  Then, the other advantage of inch threads disappears, using the chasing dial instead of screwing and unscrewing.

Best of luck,

When you reverse the machine, the spindle also reverses, which would throw the cutter up since the cutting forces hold it down when threading, IF I'm understanding this correctly. I have to rewire my Atlas, restore my 10L, and and install the Smithy, and I can't reach the HF mini-lathe at the moment, so I cannot check it on any of my machines. :( If it works that way, I may have to build a couple or three of them...
