\nAccording to the drawings, I cut the 4 lightning holes. I had to purchase a new steel hole cutter for the job.

<\/a><\/p>\nAfter smoothening the holes, I sanded the box down inside and out. Then I matchdrilled the brackets to the box, countersunk the holes and riveted the brackets. Finally I traced the holes to the firewall, and riveted on the nutplates. At last I was ready to hang the engine. It all went great, except… The oil sump interfered with the engine mount!!!\u00a0\ud83d\ude33 After spending a month or so figuring out what to do, I ended up ordering a new cold air induction sump manufactored by Superior. After testfitting it, I removed it for primer and paint. Well, that’s one issue fixed. After being pissed at myself for a day or two, I cut the flange welds carefully; bolted the flanges to the engine and positioned the exhausts in the desired positions. My good buddy Thomas is a hell of a welder, and he offered to drop by and weld it for me.. problem fixed. \ud83d\ude00

\nReady for primer and paint…

\nI had to make a slope to get it down the few stairs to my basement, then used an engine crane to lift it inside and onto the fuselage…

\nI received it about 6 weeks later, and it fit like a dream! \ud83d\ude00

\nNext problem was my exhaust system. After much research, I’d decided to purchase a dual muffler system from Vettermans. I put in the order around the same time as the oil sump, and it actually arrived on the same day.
\nUnfortunately I hadn’t realised that the system was for a parallel valve engine instead of a angle valve engine like mine, so the flanges were oriented different.
