I decided to redo the rigging of the E-MAG blast tubes. According to the manufacturer, direct cooling air to the ignition units is critical. My first attempt, completed several months ago, never set well with me. So, while awaiting electrical parts for the wings, I began the re-work.
Flyboy Accessories sells a nicely designed 3D printed conduit clamp that secures a 20mm corrugated tube. Although somewhat pricey, I elected to purchase a few for miscellaneous projects. Over the past couple of days these clamps came in handy for this project.
Since space around each E-MAG is a bit tight I needed to fabricate a mounting plate for the left conduit clamp; the right side would not need a plate. The mounting plate would be attached to the E-MAG using one if its housing screws. After some trial & error the end result prove to do the trick. The conduit clamp when screwed firmly to the mounting plate securely holds the blast tube & allows for directing it to where it is most efficient. On hindsight, the next time around I will dimple the rivet areas of the mounting plate. But, for what it is - I believe it should work well.
I plan to apply the same methodology to the alternator. Although not stipulated in Van's plans, I have read several builder's suggestions to be proactive & supply cooling air to the aft side of the primary alternator.
