I remember at the age of 11 or 12 trying to fix my bike. I asked my father for some help as I was not mechanically inclined. He looked at me for about ten seconds. Then he said nobody helped him when he was young, why should he help me. He then took a puff on his pipe and walked away. Somehow, I managed to get the bike to run correctly. Don't ask me how.
I had checked out and studied a school library book....and traced the exploded diagram of the coaster brake. In much the same way as an adult I’ve learned woodworking and fully restored my 69 VW.
