He is a really nice guy. I was having problems trying to figure out how to teach one of my totally blind home-turners how to find the center on a spindle. So I emailed him and he told me how he does it...he uses a scratch awl instead of a pencil to scratch the diagonals using a standard center finder. He can then find the center by touch and use the awl to make a dimple that the spur or live center can find by touch.
What a message this guy is giving to all of us...!
On the other hand, I find it a little strange when he says he doesn't want his vision back, I think this is the first time I ever heard such a statement from a blind person, I'm not sure if I understand it but I can assume that the loss of his vision has given him an increase and power to all his other senses and it may just be that he feels happier with that "exchange" and that I can accept.
There is a fact that we all have our own "disabilities" and parts of our body that don't work as it should, physical or mental issues can easily make us feel down and negative, nothing better than a good "reality check" to put us in the right place and consider how lucky we are.
The "looking around" expression is not always enough when we don't really have much to look at, nevertheless, looking further and passing those barriers we can see examples that we all can learn from and become better persons, a little effort can go a long way...!
