Maxwell Winch Power Ratio

I have not taken the primaries completely off, so don't really know what the base looks like. However if I were building new bases to fit the Harken 35's I would probably consider glass, or carbon finer. Ok....for Voila I would use carbon, because she deserves it. In which case I would hand shape a plug out of polystyrene foam, allowing for the thickness of the finer. If I could find the higher density foam, 2 lbs/ft3 I would prefer that because it sands and shapes better. Fit it to the boat gunwale, etc, then I would wrap it in tuck tape, used to apply vapor barrier to concrete foundations, etc. Laminate the carbon around this. To keep the resin/fiber ratio lean, when laid up, epoxy still wet, cover smoothly with peel-ply, then use dry wall fiberglass tape to wrap the thing tightly. This tape is very pours and will apply outside pressure to the laminations, but allow the excess resin to bleed through it. When that all sets up, remove the dry wall tape, and pull off the peel ply. You will have a relatively smooth finish and the peel ply will leave it ready to receive some medium density fairing material to sand off and make ready for paint. The foam can be extracted by hand, or just pour some lacquer thinner on it and dissolve it out from the part.

Another way you could consider is to use the existing bases, if the bolt circle of the 35's is small enough to go inside the existing bases. If so, you could just strip the existing bases, then wrap them with glass tape until you achieve your new diameter. Fair it up and paint.

I have the parts manual and the service manual.... the only documentation supplied by maxwell and there is no mention of ratio's anywhere
