South Bend Screw Cutting chart

[Roger HulettParticipant @rogerhulett83124]

I have a 1939 9" Workshop Model C. On the change gears cover is a screw cutting chart. Unfortunately due to the restrictions in the layout of my workshop I cannot read the screw cutting chart without opening up a severe rupture of the macro median transverse thingy in my back. I want to print out a chart so I can refer to it on my bench.The problem is that this chart does not seem to exist. I have scoured Google,Webbs,Lathes.com, but no trace.

The chart is headed SCREW THREADS POWER FEEDS

ENGLISH LEAD SCREW

and at the bottom below all the gear specs…

Cat No 15-ZBC Chart No7

Can anyone point me in the right direction to print this chart. Thankyou

Try this link, well down the page, it looks like the chart for the B and C are the same .

Lots of info on the yahoo Boxford group that applies. Not sure about the charts specifically but still worth poking around the group files.

Hi Roger,

The Australian Hercus lathe is a copy of the Southbend. Thread chart attached.

Hi Roger,

I have made a excel-spreadsheet with both metric and Imperial treads for the SB 9 lathe.
It`s in Norwegian,but its easy to translate.
Hovewer i cant find a way to post it in the forum, but send me a message and i will mail it to you.
