Using a chain-type oil filter wrench as a chain whip
You can make your own chainwhip, either &quot;from scratch&quot;, as the video below shows, or using the oil filter wrench for sourcing the base parts (handle, piece of chain).

                
            
I agree with others that the &quot;oil whip&quot; has a somewhat short handle.  Taking a cassette off can be a pain without proper leverage, so I would look for a longer (1.5 to 2 times longer) piece of metal to serve as a handle for a DIY variant.
