TLDR

• Reinforced the cowling tip with fiberglass & epoxy
• Installed heat shield on the lower cowling

Fiberglass & Epoxy

As I mentioned in a previous blog, my cowling’s gap to propeller flange is a tiny bit off (4.8mm as opposed to 5mm) and I decided to put on some fiberglass from the back of the cowling tip and sand away some material at the front.

I got the required material today, and glued 4 layers of 6mm fiberglass on the cowling tip’s back end. This should give me 1mm thickness, more than enough for what I need to sand off on the front end.

I’m using total boat 2 part epoxy

Mixed epoxy in a cup

6mm fiberglass, cut into many small strips

Glued the fiberglass to the cowling

Heat Shield

As I wrap up the work on the cowling department, I installed heat shield with contact cement to protect the cowling from exhaust heat.

Another few smaller pieces, and all glued to the cowling with contact cement
