Test Flight Preparation - Last Minute Problems Discovered 

It does more than splash the oil around - it actually pumps it through the whole system and pressurizes it, so you get oil on all the crank bearings and cams. If you watch my other videos, you'll see that I always have a full respirator on when doing glass work - unfortunately, I did not bring it out to the hangar with me, so I had to make do with a particulate filter mask - doesn't help with chemicals, but it at least is better than nothing when it comes to microballoons. The paint-on epoxy over the micro is just the same exact epoxy used to MAKE the micro (and to do the fiberglass layups). It's a trick I learned...actually, I don't remember where. Instead of laying on micro, sanding away, finding pinholes, filling with micro, sanding, more pinholes ad nauseum, you sand the micro how you want it, then a single thin layer of epoxy on top - it lays down and fills the pinholes. Then you can give it a light sanding and prime. The UV primer is Stewart Systems Ekofill - actually intended for fabric surfaces but also recommended as UV protection for glass: www.aircraftspruce.com/catalog/cmpages/ekoFiller.php?clickkey=3133197

@@CanardBoulevard I know exactly what you mean about the tedious process of filling in micro pinholes, your trick with epoxy is great! Thanks for the reply!

I actually did the last condition inspection WITH the builder when I bought they plane - he supervised, I did the work. It was a great way to learn the ins and outs of the plane. My oil cooler has a couple brackets that hold it (more or less) in place when the lower cowl is removed.

It's not the hub, it's the spinner mounting flange, and it is slight - but with the spinner installed, it's so light and such a tiny imbalance that doesn't make a difference to vibration levels.

I unfortunately left it at home, so I was wearing just a particulate mask. Normally I have a full respirator.

People use both terms, actually

@@CanardBoulevard they do but only one of them is right. A gallery is a long hallway or passage and a galley is a kitchen on a ship.

It's just in the paint, not in the underlying glass. One day I'll fix it, but it's cosmetic only at this point.

It's actually not on the hub, what you're seeing is on the flange that mounts to it that holds the spinner in place. I saw it as well, but the spinner is extremely lightweight fiberglass, and it doesn't seem to cause any vibration (or any that it is creating is being damped out by the balance ring).

Nope. Just lots and lots of reading, studying and practice.

I actually have a full respirator that I normally wear for this type of work - but I want expecting to have to do this, so it was at home, which is why I was just wearing a dust mask. But yes, I normally have my respirator on!
