Overview:
Can't put a huge aluminum cylinder on the lathe.
Can't assume the cots cylinder is perfectly smooth/uniform... it will have some imperfections and be warped.
Problem:
Screw holes are not radially symmetric (run-out tolerance is too high)
Solutions:
Get inside circular (using cylinder hone)
Allows us to clamp chuck from inside of the cylinder when radially indexing (?)
Find a way to make the outside circular, then radially index how we have been
Build a new tool to attach to drill?
Use homemade woodturner to slowly turn and sand the outside?
Next Steps:
Order cylinder hone online, replace stones with 80 grit sandpaper.
Look at homemade turning tool
