Nova Chuck Insert/Adaptor-IDNS (1" 8TPI thread)
By Dominic Garafalo from Manlius, NY on July 10, 2016
I have purchased two of these insert/adaptors for my Nova G3 chucks and they are very precisely machined with no measureable run out

I would recommend this item to a friend.

Not sure
By Mark from Ohio on January 7, 2015
I was told the insert had 2 grub screws, one to lock it to the chuck body and the other to lock it to the spindle. Whoever told me ths was wrong. I bought this for a lathe with reverse and now I'm not sure if the lathe should be used in reverse until I figure this out. Otherwise looks solid an fits fine.
Good fit.
Horrible customer service from Teknatool. May have to have a second grub screw drilled and tapped.

I would recommend this item to a friend.

Insert adapter
By Steve Carpenter from Thompson, CT on January 5, 2015
I emailed with questions and received a reply in less than 1 hour. It was good and accurate for my 1930's lathe. It only took 2 days to come in and fit perfectly.
Quality Made in USA.

I would recommend this item to a friend.
