Tiemco Ceramic Adjustable Double Arm Bobbin HD
Tiemco Ceramic Adjustable Double Arm Bobbin HD is a complete fly-tying bobbin holder in the HD configuration, combining a position-adjustable ceramic tube with a double-arm frame. The spool is supported by four stainless-steel wires arranged in pairs on both sides. This layout keeps the spool aligned while providing a broad, comfortable area for holding the tool. HD identifies the heavy-duty tube version, intended primarily for thicker tying threads and larger fly patterns.
The ceramic tube gives the thread a smooth path and helps reduce abrasion and fraying during repeated wraps. It can be moved along the bobbin’s axis and set in the preferred position: a shorter extension improves close access around the hook, while a longer setting provides additional working reach. The double arms help keep the spool square and make it easier to palm, allowing the tier to vary thread pressure without sacrificing control of the tool.
Adjustable refers to the position of the tube, not to a separate disc-drag or magnetic tension system. Seat a compatible spool evenly between the arm contacts and check that it turns without binding sideways. Then set the tube to the required working reach. Thread tension is produced by the spring pressure of the arms and controlled with the fingers or palm; consistent spool seating and a consistent grip help maintain a repeatable feed.
