Thanks for the correction on the sizing Ken. I would still like to know if this size range will work with my lathe.
TIA
The PSI version come in 3/4 by 16 and 1 by 8
Beall comes from 3/4 by 16 and larger for standard threads including 1 by 8
CUSA comes in 1 1/4 by 8 with an adapter to 1 by 8
The Woodcraft house brand comes in the headstock threads but does not use a standard ER collet.
If you can find a holder to fit the threads on your lathe -- the ER40 collets are larger -- but I have not found them for wood lathe use.
side note -- Kelton sells lathe tool handles that use ER collets -- the smaller handle uses ER16 and goes up to 10 mm ~ 3/8 inch. The larger handle uses ER25 collets and goes up to 16 mm ~ 5/8 inch. Both are very secure and with a change of collets handle everything except the 3/4 inch shank or larger tools. It is easier to take a tool out of the handle to sharpen as a bonus.
