First step was making a casting model from wood. Then the casting mold has been molded from the model by plaster.
When the plaster mold is dry enough for casting the lead it is set into a bed of sand. The feedthroughs for the S/S rods are made by using short water pipe pieces made of galvanized steel. The pipe pieces are fastened with wood screws and flat washers to the plaster mold.
For casting the bulb slabs I installed a very simple lead melting furnace.
And here you see the result of my first attempt. Not that pretty but usable.
Will covered with a thick layer epoxy anyway.

This blog will take you along the different steps of building a 23 foot dropkeel sailboat. The DIDI 23 is one of the available designs for the amateur builder designed by Dudley Dix. The boat is built as a radius chine trailer sailer from plywood with bulb dropkeel.

On the photos you see the keel foil hanging in my shed for finishing the profile.

Skeleton Almost Finished
The temperatures are falling daily. It is almost to cold for working with epoxy resin. The last Action in the greenhouse this year is fixing the sheer cleats to the bulkheads. The sheer clamp must wait until next spring.

Bulkhead Re-Alignment
Frequently the bulkhead alignment is controlled by guideline, plumb-line and tube level and readjusted by tension belts if necessary.
