I am having a bit of trouble with D1-4 mounts.
I need some basic information and I can't seem to find it
in any of the references. Perhaps i just don't have the nouns right.
On a lathe with a D1-4 spindle mount...
1. which way should the cams be turned to tighten the chuck to the spindle.
All of the mounts have the scalloped ( section cut out ) facing down,
on the six as it were.
2. how far should you need to turn the cams
Is a quarter turn enough or should you be able
to go a half turn or more ?
3.How much runout would you expect on a three jaw
chuck ? ( Really I have been using a four jaw chuck for a year now and I really don't know )
Thanks, for not laghing too loud
