    Any help on this would be appreciated.

    I have just made a ceiling mount for my HS20, using ideas from other members. Its quite a straightforward and cheap design: B&Q 400mm x 60mm table leg, piece of cut mdf, and lots of nuts, bolts and washers.

    I have figured out most of the design issues, but would like to know what the best way to secure the projector to the mount. At the minute it will just be held by the bolts that screw directly into the pj, is that sufficient?

    Im thinking about tying a strong failsafe wire to connect the mount with the extendable leg structure of the pj.....it wouldnt be very healthy to the pj if it detached from the mount, but at least it wouldn't fall on head.

    Am I missing something obvious?

    I would post some pics but I dont yet know how to, but any comments on the above would be :smashin:

    That's been good enough for my pj for the last two years or so.... and probably for lots of others too. If having a "fail-safe wire" is going to make you feel happier, by all means do it, but using the correct bolts for the mounting hole in the projector will do just fine.

    Thanks for the reassurance. I got some advice from beecee on his mount, and after he sent me the diagram I realised I wasnt using enough nuts! :suicide: Problem solved.
    If I figure out how to attach pictures Ill do that when its all up and running.

    Cheers

    There are only 3 M6 (IIRC) screws that hold my pj to the 6mm mdf board that's attached to the DIY ceiling mount, and 4 wood screws holding the ceiling mount to the wooden batten in the ceiling. You'll find that that will be fine for something weighing around 10 to 15lbs, and probably more.

    If the pj has 'x' amount of fixings to hold it to the mount, then that is all you need.

    Gary.

    whats wrong with a bit of blu-tac or double sided sticky tape? :D

    on a serious note, pics would be good as soon may go down the same route (don't make me try blu-tac first :eek: )

    hope these pictures make things clearer.

    I suppose I should get round to taking the stickers off the leg.

    Good job Chili!

    Cheap but functional, and fully adjustable I take it? Can it be rotated easily and locked into place?

    Gary.

    Thanks Gary

    At the minute the whole thing is held by the plastic foot of the leg, which is quite sturdy and adjustable. I have unscrewed the foot, threaded it thru a piece of mdf, then tightened the foot back on. The MDF then lies over and screwed into the joists.

    I still have to put a cover plate of some kind where the mount goes into the ceiling, and the mount is too low, but I have yet to figure out the solutions. I was so keen to get the mount up I haven't really seen it through yet. The improvement in quality, without using the Sony side shot feature, is reassuring.

    The whole thing cost about £17, so i am very happy I didn't waste money on one at the shops.

    If you have any suggestions how to blend this mount tastefully with the surroundings I would be grateful. The PJ is in the bedroom so it has to be fairly discreet. The PJ will be moving closer to the ceiling so that will help.

    These forums save you money :smashin:

    Cheers

    I guess getting it as close to the ceiling as possible, shorten the adjusters to a minimum, and paint the mount the same colour as the ceiling. Try to hide the cables too. That can make a lot of difference.

    The cables could quite easily be routed through the table leg by drilling suitably sized holes and fitting rubber grommets to protect the insulation.

    excellent points made....well noted.

    I suppose the mount isnt really finished yet, so I will incorporate those ideas into the design.

    thanks very much
