Washers installed
I forgot what a pain in the glutius maximus it was to get the bolts in the vibration isolation mounts (aka: engine mounts). Compound this by having to work around things like the exhaust that wasn't there on the initial engine hang.
After multiple hours of work, many scratches, multiple explicitives, and a few wishes that the hanger fridge had cold beer in it, the washers were installed.
Also, many thanks to the couple of hanger neighbors when I needed an extra set of hands.
The large washers used are 1/8 inch in thickness just like the ones that come with the mounts. It raised the spinner top approximately 1/4". The top of the spinner is now equal to the top of the cowl. Cosmetically, I am thrilled.
Since I'm flying out tomorrow I will be able to compare my travel TAS speed with previous trips. I don't know if I will see any gain but I am hoping to see an increase. My theory on it. #1 - I reduced some frontal area that was showing on the cowl by moving the spinner up and #2, if the thrust line was moved down a degree, it would potentially change the angle of incidence on the wings and possible reduce induced drag. Probably hypothetical horse manure but that's my story and I'm sticking to it.
Real results will be forthcoming.
