Rusty,

I used "Steel Epoxy" stick (dough like consistency) and added somed JB weld to smooth it out. I used it to smooth the airflow from my first manifold into the port. I roughed the aluminum runner and then applied the ball of "steel Epoxy" stick until I had the general shape I wanted, then added JB weld for smoothness. I flew it for 160 hours with no problem. The pieces are too large to go into the port even if they separated from the wall (unless like you say they broke apart).

Subject: [FlyRotary] Intake question

Greetings,

I was looking at the latest intake today, and noticed that the secondary ports on the intake are quite a bit taller than the ones on the engine itself. Attached is a picture that shows the intake gasket, thought the intake runner to give you some idea of what the size difference is. The top of the runner is fine, but the bottom, as shown in the picture, is off by about half and inch.

The question is- how many people would feel comfortable filling this in with epoxy putty, JB Weld, or similar glue?   It makes me nervous, but it would be such a large piece, that it couldn't go through the port if it broke, unless it broke into pieces.  Obviously, the surface would be cleaned, and roughed up to make the best adhesion. What do you think?

BTW- I'm off for 3 weeks, and my goal is to have the engine running, and perhaps even have the plane back in the air with the rev-2 configuration by the end of that time.

Cheers,

Rusty (time to let go of my EM-2 now Tracy <g>)
