There is no corelation between a cylinders ID to OD.
id means inside diameter, od means outside diameter, copper pipe and tubing is measured by the od, therefore the od the pipe or tubing will be the same as the id of the fitting
assuming it's hollow. 10.68*ID*(OD-ID)
Can you calculate the ID of a pipe when you have the OD to be 10.75" and the wall thickness to be 0.5"Depends on what you know about it. If you have the outer diameter and you know the wall thickness, then ID = OD-2 x wall thickness
it will vary by Tool Joint OD and ID. FYI 7"OD x ID 4" HT55 is 52,600 Ft lbs

the two producer of safty laboratory id odich[od
it means outside diameter as opposed to id which is internal diameter
wall thickness of pipe is (OD - ID) /2
Inside diameter
CID. see http://historymedren.about.com/od/cwho/p/who_cid.htm
The easiest way would be to make a bushing with the same ID as the OD of the shaft and the OD as the ID of the pinion. If there is no great load on it a press fit might suffice. If there is a heavy load, the bushing and shafts would need to be keyed to prevent spinning. This is assuming that we are not talking about an automobile ring and pinion gear. The loads and stresses imposed on an automobile ring and pinion are too great. ID = inside diameter OD = outside diameter
