From an old catalog:

Series Lathe Swing (inches)

12 ........ 20+
77 ........ 16 - 22
7 ........ 16 - 22
5 ........ 13 - 18
44 ........ 9 - 13
11 ........ 8 - 11
14 ........ 6 - 8


For some reason, the new catalogs don't seem to have this information.

Perhaps the company feels that machinists a just that much smarter these
days! :-)

On the topic of Dumore, does anyone know of a webpage with an
accumulation of data on their toolpost grinders? I am wondering how all
the wacky older models that show up on Ebay relate to recommended lathe
sizes. For example the smallest and largest lathe each would be
appropriate for? I have looked around on www.dumorecorp.com but even
the current models have minimal descriptions. Thanks.
