    I have heard of problems with helicopter props

    I had my first bss inspection back in May. The geezer was very thorough and informative. If one owns and uses a boat on our waterways, one must expect to pay for the privilege. I paid 180 quid for about 5-6 hours of a qualified chap's time and expertise. A bargain I thought

    Our prop is a four bladed 21x18 originally from a sea going trawler. It only travels at 300rpm so have no idea if would sing or not at high speed. Reading about your dilemma, it's a new one on me. I had no idea this do at tbof problem occurred. Do aircraft have a similar problem I wonder?

    It's a hanging offence to drill a hole through our monarchs head

    Great news Jordan. How about injectors and injector pumps?

    Bought a used generator from them. It was buyer beware and took a bit of sorting. They were selling it for a customer. I'll let you know how it performs when it's in my tub

    Well, I wouldn't call it excessive, but yes the INTERIOR dimensions of the deckhead once battened out is 1475mm

    The bed slats workshop will supply custom length slats. I've ordered 200 slats at 1475x63x10. They come to 1175 quid. Half the cost of beech par

    The ceiling is battened and the radius of the curved beech is smaller hence they are pressed up each end which tightens the centre upwards. One could fix the slats each end and cover the fixings with the side wall panelling.

    May well do that?

    It was an idea that I came across whilst looking for par steamed beech which is quite expensive. New bed slats are cheaper and are shaped in a curve. We require light coloured timber as only have porthole windows and much as I like oak, it's too dark. The slats are the same thickness and have rounded edges that create a chamfer look when together. It's machined ply so very precise

    Anyone out there used sprung beech ply bed slats to line a narrowboat ceiling/ deckhead? Going to see if it works using 1500mm steamed beech oiled ply.

    Hi Jordan. Would like to purchase a 3VSHM head gasket from you to carry as a spare. My number is 07495057403. Pete Duddigan

    We'll, it all runs ok. Gotta wire in the starter battery alto next. Advice welcome. At 495 engine rpm the intermediate drive runs at 890rpm and the alternator pulley runs at 3065rpm. Tested all speeds with a cheapo Chinese digital tachometer.
  16. Peter Duddigan
    Haha. Great ideas. Truck horns it is?
  17. Peter Duddigan
    Thanks for advice. Heed taken. Funny you should mention air con....? and an air compressor. Don't know why, just fancy fitting one. The Ruston has a spare pulley running from the camshaft, used to drive the water pump.

    I'll ignore Magnetman. Bet he's a Bah Humbug character. Of course the paint will come off, who cares. As for the bearings they are skh and will only be spinning at 1200rpm. They'll see me out. FYI there are two alternators. Both alternators are clockwise running and fans run in correct direction.
  19. Peter Duddigan
    These pulleys will up the alto speeds to 6 times engine revs. Awaiting v belts to arrive. Made the adjustable pulley carriers to suit. What d'ya think?
  20. Peter Duddigan
    That's what I meant by initiative??
  21. Peter Duddigan
    Great to read these stories. Using initiative to create a working idea.
  22. Peter Duddigan
    Great. I may run an extra alternator in that fashion later on. Many thanks?
  23. Peter Duddigan
    There's nothing like using your ideas and creating something that works. Using the flywheel is a good idea but I'll stick to my plan to up the drive speed via pulleys. Thanks everyone for your thoughts and knowledge. I'll let you know how I get on?
  24. Peter Duddigan
    I'm impressed ??
  25. Peter Duddigan
    That'll give an alternator speed of 5000rpm on tickover, a top speed of around 17000. No thanks. A larger pulley on alternator would reduce this but I'm not going that route. The belt length would be silly. I'll prob up the idler to 200mm, giving an alto speed of 4000 plus at cruising and a max of 7500
