Hi all
I'd like to draw upon the collective wisdom of the you all. I've just bought a direct mouning (no back plate) 6" 4 jaw independent chuck for my Super 7 and am far from happy with it. With a decent quality test bar dialed in at the jaws, there is a good 1/8" run out at 12" from the chuck. The chuck body does not sit parallel to the spindle axis - the rim wobbles by about 15thou. Not much good really so obviously its going back to the well known supplier. I won't identify them until they've had plenty of oportunity to rectify the situation.
Given that I can't afford genuine Myford prices, what is everyone's experience of recent purchases and suppliers? Perhaps a backplate mounted chuck would be a better idea. At least then I can make sure its machined carefully to get the chuck parallel and concentric to the spindle. Any recommendations for a make and supplier?
cheers
Toby
