Creating the Fine Bow on the Port Hull

Category: Building an Oram Hull — Babbled by Judy on July 2, 2005

We’ve just finished fitting the PVC tubing to the port bow, and Tom is at the moment busy planing the hardwood sacrificial keel edges. Since it’s been a while since I have posted here, I shall take advantage of Tom’s preoccupation to describe what we just did.

Sealing balsa edges with resin

Above, Tom is sealing the raw balsa edges with plain resin.

Applying fillet/glue to bow prior to attaching PVC conduit

Above and below, applying a fillet of 50/50 silica (Aerosil) and microspheres (QCell) to be the bed for the conduit.

Pouring runny glue mixture into PVC conduit

Tom is pouring in a glue mixture made in the same manner as the fillet, but with a higher resin to powder ratio.

Bleeding runny glue mixture before plugging

Hopefully allowing the glue to flow freely from the other end before plugging has successfully bled the conduit of any air bubbles.

Plugged!

Ensuring conduit is filled with the mixture

Plugging the top end with some firmer fillet mixture

Above, Tom is plugging the top end of the conduit with left-over, thicker, fillet mixture.

Positioning the conduit

The rising temperature of the curing mixture in the conduit makes it easy to bend it to meet the curvature of the bow.

Positioning and temporarily taping the conduit

Temporarily holding the conduit in position with gaffa (duct) tape whilst everything sets.

Tom applied a bit of pressure to align the conduit to the bow here. Fortunately the gaffa tape holds it in this position.

Excess glue needs to be cleaned away.

    Hi Tom;
    I like your website. It is maintained in different way, but very easy to navigate.
    Your project is fabulous, and you are doing excellent job.

    OK,
    having been a wet blanket on rig and grounding strip, I like what you are doing here!

    Is that PVC pipe like garden hose, of hard plumbing pipe?

    I’s a fabulous boat.
