Re: Re: Whoosh, thud - motorised sliding doors

David,

Great idea, I hadn't thought of that one - the motors are nicely geared
and high torque as well, so they would probably be up to the job of
hauling the door (though I may need 2 of them!).  I'm off to the
scrappie at the first opportunity, although I always come back with a
pile of stuff I didn't need having invented new projects for it 'on the
hoof'.  Thanks again.
