  • B&H 500 series issue - part needed

    Hello, Thank you for letting me join the forum.

    I have a B&H 545 which is a bit of an oddball model being 110/240V 50/60 Hz, instead of the silent / sound belt shift it has 50/60 Hz.

    it is in pretty nice condition and the worm only has one tiny crack at one edge. However I decided I would swap it out anyway.

    I had run some films and it had a fairly noticeable level of flicker, much worse than the old B&H 202 I have. examining the shutter it has lost part of the leading edge on one blade probably 1/4" or so, it looks like some one has dressed it with a file to tidy it up a bit . It is also odd in being a two bladed shutter but this could be correct as the service manual says 2 bladed shutter for export models. I guess more light output at the expense of flicker?

    Does anyone know where I can find a replacement shutter or a donor machine? I realise that new parts are next to impossible but does anyone have one in their bits boxes? Any help gratefully received.

    Failing that all I can think of is making a new part blade and getting a very good company I know to laser weld it onto the damaged part, but that may be more than the machine is worth in cash terms.

    Do you feel competent to replace the worm yourself? This is an auto-load model which requires even more setting up.
    I can recommend an engineer in Nottingham who could do such work and give the projector a good overhaul.

      Thank you Maurice,

      I am pretty good with things like this I have been an Electro-mechanical technician for about 40 years, sadly this is now a dying art with the throwaway society we have. I make it my mission to rescue old equipment rather than buy new if I can.
      I will see what KB can do. I think it would be a better projector if I can get a three bladed shutter on it.

        Kevin Brown has kept my projectors in tip top shape (including new worms) for over ten years. I can highly recommend his work. Give him a call, I am sure he will be able to help.
