Everyone,
Delta design uses a different tolerance for "Drilled holes" on their drawings (flip tray). This is ambiguous as the definition of "Drilled hole" is not clear.
I spoke with Wattana and from now on we will consider holes used for fasteners (screws) are 'Drilled holes'. All other holes and pockets use the standard drawing tolerance.
For example, the 30mm diameter hole in part number 8333235101 is not a 'drilled hole'. It is a circular pocket for all intents and purposes.
If there is any confusion which tolerance to follow for a specific hole please ask Wattana before making changes.
Thank you,
Jeff A.
