7 hours.<\/p>\n

Spent a good portion of the day iterating the front inboard baffles. This is where it gets weird: I used the IO-540 baffles from the RV-10 kit as a template to modify the baffles that came with my kit. Pretty straightforward, except that the hole for the governor is going to be very interesting.<\/p>\n

\"baffles_front\"
\nThe process here was pretty simple: Trace the outline of the 540 baffles onto the 360 baffles supplied with the kit, then cut away the excess. The 540 baffles sit a little farther back on the engine, behind the bulge for the governor drive gear and governor pad. I had already spent a good bit of time yesterday trimming the left front baffle to fit using more or less the same method, except I screwed it up a little. I didn’t leave any metal crossing over the centerline of the engine to link the two halves up. No big deal, that’s what spare .032 and platenuts are for.<\/p>\n

Since the right baffle sits a little bit more aft, I needed to cut down the bottom of it about 7\/8″ and cut the forward part straight back. It turned out OK, but left about 1\/2″ of difference at the top from the left side. This is not problematic either, really, since a good chunk of that material has to be removed for the cowl fitting.<\/p>\n

\"baffles_front2\"
\nI’ll also have to extend the sides out to just past the ring gear on the flywheel, since the front baffles are now mounted too far aft.<\/p>\n

I got my replacement #4 cylinder baffle parts, so I worked on those for a while. I”m not going to tackle the oil cooler until I’ve trimmed the baffles down for cowl fitting.<\/p>\n

Speaking of which, that happens next. I have to get the spinner off the prop, make some 2 1\/2″ spacers, and get my spinner put on the engine so I can line up the cowl. We’re about to head back into fiberglass land, folks. Yay! The entire world will be covered in pink dust. Like a Chtorran invasion site.<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
