Brief Description:  Mounted Engine to Airframe

This was the big day. Well not THE big day, but a big one nonethless. Started out by replacing the temporary bolts on the engine mount with proper AN hardware.

Then it was time to figure out how to raise the engine. My rig is based on a hoist I got from the aviation tools department at Harbor Freight. Rated at 440 lbs, it was more than adequate for the task. Cut the ties securing the engine to the pallet and adjusted the engine so it would tilt and be near the rear edge when in correct orientation. Found a couple of good locations and attached a couple of straps for the initial tilt. Used the hoist to tilt the engine into an orientation with the mount points level. Added and adjusted straps to lift in this orientation. Placed hardware through the mounts from aft side to act as guide. Once level, a final strap adjustment got the holes to line up and 3 of the 4 mounts were attached with no issues. The upper pilot side mount point on the engine had a moulded flange which prevented the rubber and large washer from fitting, so I ground them down just enough to allow the mount to seat and the washer to compress the rubber. Tightened the bolts just beyond bottoming on the spacers. Released the hoist tension and the engine stayed put. I had nightmares about the engine crashing to the concrete and shattering into a million cast metal shards, but fortunately that didn't happen. It really is amazing that what looks like such a flimsy mount can hold that heavy engine.

All in all, everything went much better than expected.
