I really like my "new" 15" Colchester.
However, I miss my 4jaw. Just seemed to hold everything tighter without cranking on the chuck jaws. I don't find that set-up really takes that much time.
Courtesy of Ulmadoc I've got a vintage 10inch independent 4jaw which I can mount.
This spindle takes a D1-6 backing plate.
The diameter to the shoulder is a little less than 6inches.
This includes both the D1-6 camlocks and the mounting screws to the 10inch periphery of the chuck itself.
My question:
Should the backing plate extend to the periphery of the chuck?
Or, is it adequate to extend only as far as the shoulder?
I'm actually wondering if a 6inch backing plate with a press fit is advantageous, as she'd have less rotational weight and would allow a hand to hold the recessed cavity in the back of the chuck.
Note: I purchased a 10inch D1-6 backplate online. Then the eBay vendor canceled the order, refunded my money, and relisted at triple the price. Arrrgh.
Thank you!
