On the NTE site, I couldn't find one mention of the issue being discussed.in case you think I am a lone wolf making these claims, here's some corroboration I found in 2 minutes:
Lathe Spindle Nose Standards & Lathe Chuck Mounting Types
When replacing a lathe chuck on your machine, you need to choose the right direct mount chuck or adapter plate. More on lathe spindle nose standards here.www.northlandtool.com
What's the proper fit for a D1-6 chuck to the spindle register?
This is a 17" lathe fitted with a 8"-D1-6 Bison chuck. When I mount the chuck it takes some finesse and tapping with a dead-blow hammer to fully seat it on the register..it's more than snug. Today I realized that run out is dependent on the sequence of tightening the cam locks..tightening them...www.practicalmachinist.com
On the other reference, all I read was personal opinions. Not a single reference to a credible industry or manufacturers document that speaks to the issue.
I would appreciate a through description of the process you used to lap those chucks.
We have many members that have bought new lathes that are supplied with chucks and owners manuals. Are all those chucks tight against the spindle nose? Is there any mention in the owners manual for "properly" fitting a new chuck?
