MWD centralizing rubber fins can be cut safely and precisely using this system. Proper centralization will prevent damage from shock and vibration and improve down-hole survivability. The aluminum cutting block can be latched around the tool so fins can be cut perfectly to ensure good contact with the inside of the drill collar.
Even with exact measurements rubber fins sometimes require minor adjustments to allow the tool fit correctly inside the drill collar. Each side of the cutting block is a different thickness that corresponds to the most commonly used drill collar IDs.
