9ft long hone extension shaft

[Toolmaker51]

Bushings for spindle bore, or "liners" need not be complicated or numerous.
Unless very small material, 2 make a good set. One rides behind chuck, the other pulls along with material. Quite easy to pull out by opening the jaws, stub can chuck up without them. Through a collet, it's easier to push or blow out. I guess a length of cord would do as well.
Smaller stock runs fine in them, either bored to size [numerous] or with 3 or 4 small set screws to tie material and it together. Most will find 4 easier to adjust. Outside diameter of liner can be about .005 under spindle diameter, and about 1 diameter in length to not bind when being advanced or removed.
Push a rag through beforehand and proceed work with one less concern.
