jiggering
Fiddling with something
Jiggering is tampering or manipulating something, often with improper intent: Someone's been jiggering the accounts.
The word suggests fiddling with mechanisms or numbers to produce a desired result.
In pottery, jiggering is a specific technique using a rotating mold and template to shape clay—a more innocent, technical sense largely confined to ceramics.
