About 15 years ago, I helped a gentleman build an 'experimental' in his garage. I think I spent a lifetime drilling and installing pop rivets! Watched him 'bake' and 'freeze' pistons and engine block in order for them to fit snugly. He called the plant that sold him the kit for technical advice a few times, which they gladly provided. Passed his FAA inspection with flying colors and flew it quite a bit. (No way I was going up!)
