3520a Spindle Lock

>Here's how I modified my 3520a to keep the spindle lock engaged.
It's just two holes in the button guard, a 16d duplex nail, and a small cable tie secured behind the guard.
Works like a charm and took less than 10 minutes to do.

What are the remifications if you switch the lathe on with the spindle locked?
