I've swapped out several axles on the old bikes I buy. I bought an old 80's something Raleigh that looked like it had only been used once. Not a scratch on the bike. Rear axle was bent so bad that the wheel wouldn't even rotate. It was a solid bolt on type. I ordered a replacement that included the cones, spacers, washers, & locknuts. Never considered trying to put wing nuts on it. But, what the heck. Sounds like a cool idea.
