Default Collet recommendations/experience for Harrison Lathe



For production work, the lever type draw bar setup can't be beat. Also, the
Hardinge/Sjogren type chuck can get difficult to use when lots of coolant is
being used (tightening the wheel gets difficult.)


For production, the rear closer is the way to go, which is more-or-less
standard on the HLV-H as the spindle has a 5C taper.

Sjogren transferred manufacturing of his circa 1929 chuck to Hardinge, where it
became the Hardinge-Sjogren.

For the past decade, give or take, the Sjogren chuck has been made by ATS
Workholding, and all support is from them.

The Sjogren is perhaps the best add-on chuck, and with inside/ouside threaded
collets you can do repeat work, using an adjustable stop.
