More Lower Cowl Work and Oil Lines

Continued working on the lower cowl modifications.  Additional Micro/Epoxy mixture was added to fill in the fiberglass weave and imperfections.  After allowing it to dry, it was sanded down.  The excess fiberglass on the inside of the cowl was removed as it was no longer needed.  A coating of filler/sanding primer was sprayed on the part.  This is VERY revealing and immediately highlights the imperfections.

We spent a few hours planning our firewall penetrations and what would mount on or near the firewall.  This was needed so we can start progressing toward installing fuel and oil lines.

We plan to have an oil fluid thermostat in our system.  This will hopefully help keep the engine oil at a more appropriate temperature, also allowing the engine to warm up faster, bypassing the oil cooler until the temperatures of the oil are elevated.  A bracket was made and the oil fluid thermostat was installed on the firewall.

Two oil lines were built and installed.  The first one goes from the bottom of the Rotax engine and to the oil tank. The second oil line was run from the oil tank to the oil fluid thermostat.

Hours: 12
