13.8.1 Magentometer Bracket

This entry is part 12 of 67 in the series 13 - Electrical / Instruments

Instead of the traditional whiskey compass, I’m going to have an electronic magnetometer. And for redundancy, I’ll have two.  I was originally planning on having one in the outboard pocket of the right strake and the other in the left. But builder Andy Millin put both of his in the same location.  I was worried that there could be some interference issues if both were in the same location but it would appear that my worries were unfounded. 🙂

So I simply copied Andy’s design.  Imitation is the sincerest form of flattery, right?

The support bracket is a 2″ piece of 2″x2″ angle stock. That will be screwed into a hardpoint which will be mounted to the outer part of the strake.

This the spot on the strake where the hardpoint will go. The area has been sanded and structural adhesive and been applied.

Hardpoint positioned and adhesive is cured. Now it covered with 2xBID.

The mounting platforms (one for each magnetometer) are made out of 1/8″ aluminum (which is much stronger that needed) with holes to reduce weight.

Then I cut some 1/4″ aluminum tubing to create the spacers between the two platforms. Some 1-1/2″ brass screws, washer and nuts later:
