Removal of a suntour xc pro cassette??

[FluffyChicken]

Just having a mad moment here.
I recon 2 people with 1 chain whip a bike and a turbo trainer could remove the locking sprocket.

Wheel in bike.
Bike in turbo.
Chain on largest sprocket.
Person 1 on bike.
Chain whip in 12t sprocket with person 2 holding it (preferably with an extender tube to get their hands clear of the wheel and cranks).
Person 1 stomps on pedal - Bob is your mothers bro.

Person one snaps chain, crutch flies into stem, cursing follows

Make sure you film it when you try that method worst case you make £250 off harry hill.

ooh
or
person 1 pedals, Person 2 has extended tube suddenly whip up between their legs causing them to suddenly collapse on the floor.

I'm not keen on injuring myself, others or the wheel. Thankfully I don't have a turbo trainer or I may have tried, but I don't have any friends either so a non starter

I think I will get it to the lbs and let them deal with it.

Chain whips are dead easy to make. They're just lengths of bar stock with 2 holes drilled in them.

I have on occasion in an emergency wrapped an old rag (or steal a tea towel from the kitchen - they're nice and long) around the cassette then behind the big cog so the towel/rag wedges between the large cog and hub flange. Have someone hold the remaining end of the rag with one hand and put pressure against the direction of force on the part of the rag wrapped around the cassette teeth with the other while you hold the rim and unscrew the small cog with your one whip.

*EDIT*

After posting I had an idea on how to do it by yourself. You'll need an old chain you don't mind sacrificing by clamping it in a vise. A picture is better than the long essay I'd have to write to describe it, so I went out to the garage and mocked up the technique.

I used to use an old chain held to a door frame with screws.
If you don't need the cassette then do that and use a hammer and chisel on the other cog to turn it.
