My dad's got an old Black and Decker hand drill from probably the 60s or 70s (wired, as I'm pretty sure it pre-dates anything cordless) which still runs but is languishing in a box as he's concerned it's not safe. The reason for his concern is that the motor at the back sparks when it's in use (admittedly quite a lot, and it's metal-bodied). However, I recently bought a new B&D cordless and noticed that it sparks a little when I run it as well, which has made me think it might not be such a big issue. He has a cordless as well but the old drill has loads of really useful accesories (like a circular saw, router etc.) that simply don't fit any other machines. I'm wondering if anyone can advise on whther or not it's something to worry about, if it can be repaired and what kind of place I should take it to for repair? Small engineering works?
Thanks in advance.
