Fairly simple to build fly line winder for adding backing and fly line to a reel and removing line for storage.
Materials consist of wood (preference is poplar...easy to work and tight grain), several bolts & washers, a couple screws and two purchased components:
1. Line Counter (purchased on eBay from China for under $10.00 (shipping included)
2. Butt section of a fishing rod to use as a reel mount (if you don't have an old rod to cannibalize, then buy the cheapest rod you can find, probably $8-10.
Attached video shows the device and how it works. Attached PowerPoint presentation shows the design drawings
Device, as shown, does not yet have a wood finish (e.g. polyurethane). It can also be aesthetically improved with beveled edges on the wood and some additional contouring using a router. Also, I plan to replace the rubber feet with suction cups, which will aid in stability when winding.
Works extremely well for multiple functions related to fishing line loading and removal.
