Like others, I had no plan. Simply accumulated spare parts as I shopped thrift stores, yard sales, bike swap meets & e-Bay. I kept some good bikes as I built & flipped my finds. Parts were stored in numerous cans, boxes & drawers throughout my garage workshop. I usually had most parts on hand for my projects & had little difficulty finding whatever was needed.
This worked well for years but everything changed when we decided to sell our home & build another in Oregon. I sold or gave away many parts & projects. I did a thorough clean/throw out in the garage but held off packing my tools & bikes for moving. Now we have a buyer & its time to get moving & relocate. This will be hard but I needed it. I hadn't noticed my cluttered work area until facing up to a move. Don
