Tony:
When I make these type of ballast holders, I do the following:
I use 4 mil polyethylene painter's dropcloth. I cut a piece
that will make 2 or so wraps around the dowel. I thake separate
piece of plastic, lay out the Fiberglass, add resin, squeegee off the
excess, and carefull wrap it around the mandrel. Vac bag and let
cure. Afterwards I can plea the plasctic apart and you basically
have a rolled piece of fiberglass. Then I place this around
whatever I will be using as ballast, and CA closed, or even epoxy
closed. If you wrap plactic around the ballast, I find that the
plastic will permit the madrel to slip out. It all depends on how
much play you want around the ballast.
Good Luck
Chris

I needed a fiberglass ballast tube, 1/2" i.d. x 18" long. I rolled some mylar around a 1/2" dowel and fiberglassed it -- it came out looking great. However, I can't get the doggone thing off the mylar. I can get the mylar off the dowel, but can't get any farther.
Next time, more wax on mylar. But can anybody tell me if I can save this one, or do I have to throw it away and try again?
