Compass Installation.

 

Taking advantage of the Black Friday sales, I purchased a SILVA brand bulkhead compass (Model 70P). I also purchased the lighting kit.

I have previously ran a NAV light wire through to BH 2 see the "Electricals" Post dated Dec 29th 2023.

Using the supplied template, I cut an 85mm diam hole in BH2 and the four securing screw holes.

And here is the compass temporarily screwed in place.

Next, I need to build a thick timber backing block to protect and insulate the compass from the cabin area and reduce any magnetic or electrical interference which can cause deviation.

The dimensions are drawn onto 2 pieces of 20mm thick scrap timbers.

The first block is cut out all the way through, and the second block is routed out with a chisel and burring tool.

When joined together the round rear ball of the compass will fit neatly in the hollowed section.

The two sections are glued together and held in place with weights.

Routed, sanded and the first coat of epoxy.

After 3 coats of epoxy and 5 coats of Aquacote the backing block is epoxied in place. Inside cabin view.........
