The idea is technically correct, however 1.875 is too big to fit in 2.0x.125. When it is reduced to the 1.75x.125, he combined MOI is equal. This is assuming that the nominal vs actual diameters and wall thickness are exact. Mind you, I am not advocating that sleeving is never worthwhile; I am only saying that it is not a worthwhile effort to go and purchase the tube to make your own when you can buy the product ready-made.

We have a simple little Excel MOI worksheet that generated a .537 MOI with 2.0x.25 DOM ..
It generated .325 MOI on 2.0x.125 and .264 on 1.875x.125... for a total MOI of .589... in theory doubled tube is stronger correct?
