thanks
 
If you have access to a lathe with larger jaws make some collet blanks out of your stock , 3/4" or more tenon just under the max your jaws will open and put center on the blank end , you'll waste some material but the price you pay for your capacity ... Now you can pet tenon in your chuck and center in your tail stock and turn an bore ... I bored mine with the inside matching butt taper , mark which side is larger on each ... Your blanks of forearms or butts don't have to be uniform in size for these collts to do their job ... If your trying to get zero runout this might help ...A note about delrin and temperature ... It expands in heat and contracts when cool so pay attention to your tolerances when fabricating and the temp. of your shop ... :cool:

he can still do this without access to a larger chuck
i did it, by turning between centers
used my router to get one end small enough for my chuck
chucked up that end and used a steady rest for an 18" long piece

You know of a bearing with 1 9/16 ID? :)
 
Mason,
How many do you need and I need exact sizes. I will get you a price from there.

did i miss something?
thought he was trying to turn 1.75" or 2" delrin to 1 9/16"

HE needs them bored too after turning down. His collet can only hold 1 3/8.

His collet can only hold 1 3/8
you meant chuck, correct?
yeah, i realize that
i did while workpiece was in the steady rest, with the first couple of inches of 2" delrin turned to 1.375" to fit my chuck ;)

He could of course. :)
Put the 2 inch between centers, turn 1 inch down to 1 3/8 and 1 inch or so down to 1 9/16. Stick that inside the bearing while clamping on 1 3/8 by 1 inch and start drilling. He'll waste that 1 by 1 3/8 after parting if he can't recycle it.
