    Am currently (trying) to build myself a projector lift, so that when not in use projector will be out of sight... having cut hole in ceiling there is no turning back now! Just been out in garage with router and bits of wood... :eek:

    Its prob going to be a manual affair as I have been searching the web in vain for lightweight (and cheap) motor that could lift say 10Kg up by 30cm. Remote would be good too! Have been looking at garage door openers but these are expensive and cant find anything that would do without serious metal work. Other things have looked at are radio controlled winches for model sailboats (not powerful enough) and chain hoists (too heavy).

    Any ideas gratefully received! :smashin:

    Will post pics of finished article when its all in place. If manual then will simply push up in place and use couple of loft hatch type locks to keep it up... but would rather pull it up than push it :rolleyes:

    Windscreen wiper motor? Starter motors are popular for all sorts of things aswell.

    However starter motors (and possibly wiper motors are series wound so will only turn one way).

    Also, you can always increase the lifting power with gearing (pullys and belts are easiest). If there is room above (or down one wall) use a counter weight. Once again you can gear the counter weight (move twice the weight half as far). You should be able to make the platform etc weigh nothing (balanced by the counter weight) so all you have to overcome is friction.

    Thanks Maff... have been thinking that motorising the whole thing is going to be a non-starter and had been thinking along the counterweight idea... have been to local sailing shop to look at some nice pulleys and thin kevlar ropes that wont stretch... and reckon this is the way to go as adapting a motor and getting it to stop in the right places is going to be beyond me :rolleyes:

    Cheers for the input :thumbsup:
