Metal Work – Components

Winter of 2013-2014 has been a winter or drawing, planning, un planning, welding/cutting up some bits, and soon enough welding them into, onto, over and under the hull

Below is a series of pictures showing the Dickin-Schinas designed safe-transducer fittings coming together

 

And i’m making some bits to hold the wood bulwark/toerail above the metal buwark top. These pads of 304ss will support the wood bulwark and offer attachment points for rigging.  pics to come.

Radar Mast- supports radar, wind generator, pv panels and stern light

The mast it’s self is 2 1/2″ sch40 aluminum and sits in a welded tabernakle that is constructed of 1/4″ ss. The following pictures are of the mast hardware and hoops that have been turned to size on a lathe and then had tabs welded.

 

 

Winter 2016/2017

I fabricated 22 blocks with 1/4″ aluminum cheeks, solid/turned delrin sheaves 2 3/4″ in diameter, the sheave has a oil-lite bronze bearing pressed in, and the pins are 3/8 stainless steel bolts, spaced with 3/8 ID / 1/2 OD ss tube.

 

Sheaves

The delrin was sliced from a 36″ x 3″ 2 7/8 rod using a table saw with appropriate blade. It was then placed in lathe chuck and faced both sides. When this was complete i centre drilled and faced the outside radius. I then enlarged centre hole for press fit to lathe mandrel, Grooving of each sheave commenced at this point.

I borrowed some radius gauges and made myself a set of (lathe) cutters for the sheave grooves. I tried a single cutter but the diameter of 5/8 was often too much for my small lathe. So this was split into 2 half diameter cutters.

Despite the firm press fit for the mandrel, many of the sheave blanks continue to slip when any real cutter pressure was applied.

 

Block Cheeks, Pins and Axles.

I cut the aluminum cheeks from 3″ x 1/4″ flat bar, cut them to shape on a bandsaw, sanded all edges on belt sander, and them took them to a friend with a vibra-polisher to tumble them.
