I removed a bearing in a blind hole with sweet potato and a dolly

I had this flywheel bearing in a hole and had to remove it. tried slide hammer pullers and they broke. What next hydrolics! Sweet potato was the preferred choise so I cut two circles of sweet potato into circles about 10mm long. then I made a dolly in the lathe the same size of the id of the bearing. put the potato into the hole and inserted the dolly and with one hit of the hammer the bearing guts came out leaving the outer race.
New dolly was made to fit the id of the outer race and two more slabs of sweet potato were inserted and the new bigger dolly put in the hole and with one almighty hit from the hammer the outer race moved it took 2 more hits ,race removed.
Now you know why it is called sweet potato.
