I know many of usare annoyed at our jib sheet lines hanging up on the extrusion point on the mast tender system, so I have decided to try something myself in the way of a collar or boot .
The idea is, this will cover the extrusion with a round smooth cover to allow the line to slide over it rather than catching it.
I've cut out a few jig pieces to start with and will use foam to shape and then Fiberglas the entire piece. I think there needs to be an upper and lower cover that meet at the hing point, this would I think parent the lines fron catching either from the top of the extrusion or below the extrusion . It might be that my design will be a one piece unit using the extrusion as the plug that will hold the cover in place. It would only be in place when sailing, not permently attached to the mast.
I need to buy some foam, not too sure what to buy, I know fiberglass resign will just destroy some types of foam , so, any suggestion ?
I would really like to make a proto type and have an injected modeled one made as I think it would be a better looking finished piece rather than my Fiberglas home job. I've seen some crude vacuum devices you make your self but not sure if I'm up to it.
