My interest goes back to my Grandfather. He used to say that if you got the opportunity to learn something, go for it as you may not know when you might need the knowledge. Of course, that usually prefaced some task he wanted me to learn so I could do it for him, such as caning a chair seat. In his retired years, he established a woodshop and it was a fascinating place so really piqued my interest. As his eye sight failed, he would often ask for help. It was certainly distressing to see him try to assemble something when he had to install screws by feel. I think of him often as I spend time in my shop.
