Any chance the bore is tapered and you really only need to sleeve the upper end?  I was headed where Jim B. went with the fixed slider and rotating boring bar.  I guess once you have the setup done, it doesn't make much difference how deep you bore as long as the boring bar is stiff enough to handle the cantilever.

Thank you for your response.  The sliders are blind at the bottom.  Bores about ten inches deep.  This might be more easily done in a vertical mill.  Photo attached.

I would suggest you Invert the project. Instead of rotating the work, rotate the tool. 

Remove the compound. Make a fixture that clamps to the cross slide that holds the part of the fork to be worked on, ON Center. 
You said its 2-3/4. A piece  of aluminum, say 3.5 by 3.5, clamped to the cross slide. With a dead center you can mark the vertical center. 
Then cut the piece along the center mark and, using two bolts, bolt it back together. 
Set the cross slide so the clamp is at horizontal center an NOTE THE POSITION ON THE CROSS SLIDE FEED.  (if the hole is a bit off its OK AS LONG AS YOU CAN GET BACK TO THE SAME SPOT.)
Then starting with drills, drill through to the largest drill size you have. 
Now mount a 4-Jaw chuck and use it to hole a boring bar, or a fixture that mounts the boring bar. 
You can use the 4-Jaw to set the offset of the boring bar or holder + boring bar to machine through until you can FIRMLY clamp the 2-3/4”. Say 2.745” 
Now mount your forks. 
You can machine the ID’s to your hearts content.

 Hi John,

Thanks for your help. The fault was the fact that I had never seen one of these before. I finally hit on the idea that I should screw the collet in all the way and then back it out until the lever would lock. I didn't realize that it would be such a fine adjustment.

Thanks again, John.
