Prop balancing

[Davidv]

Mine were turned in the down position but only on the left side which tells me it was probably an A&P who worked on the plane and didn’t know which way they are supposed to face.  Now that I’ve flown the plane for 4-5 hours after turning them in the right direction I’m going to see if they are sliding down on their own.

This is a post mx pet peeve of mine. Properly installed baffle seals do not “blow back”, the are often not dressed forward by the person installing the top cowl. I can’t tell you how any times I’ve had to reach in and roll them forward with my fingers (easy with the old guppy mouth cowl) after the plane was in the shop or the cowl removed by one of my partners. Rear CHTs see a significant bump if the seal is opening under air pressure.

This is also true if you have the doghouse.  The forward edge of the top part of the doghouse has baffling material (mostly rubber or some similar composite) and some folks who work on the aircraft do not always make sure that it is tucked into the top of the cowl.  I have had to tuck it in more than once this year following an oil change.

This new prop balancing tool looks super accurate and somewhat idiot proof. I'd favor a shop if I knew there was one nearby that had one.

We just bought one here at GAI.
