  5. Swing bridges on the L&L

    I've watched this vid a few times, and wondered why he pulls the boat over to the towpath side. Why not just walk over the bridge and get on the boat where it is?

    The objective of the video was to demonstrate how a single handed boater could operate the bridge with minimal physical activity. You will note that there is no running or jumping around the structure or any agile manoeuvres. It was a demonstration for mixed age and physical ability. Upon closing the bridge the operator untied the boat from the bridge and retrieved it by pulling from the towpath rather than take a precarious shortcut from the offside. The structure on that side coupled with the vegetation is not particularly inviting.

    The video was submitted to a planning inquiry to help stop the 440 houses that are now to be built on the adjacent green fields. The bridge will be replaced with a fully automatic two lane swing bridge twice the size of the current bridge, it being the primary access road to and from the new housing estate. The new bridge will have the usual 'brand new teething troubles' and in time will become as reliable as the others in CRT or council ownership.

    CRT has moved the controls to the towpath side and have done so to most of the electrically operated swing bridges in their ownership. The council owned swing bridges retain their offside controls.

     

  6. New marina

    in General Boating

    It was I asked if I could create new online moorings near 119 and they told me that a new marina was going to be created in that area. Mind you they said the same when the bridge number was 199 which I corrected so what is the problem ?

    Not a new marina but a new housing estate is going to be built next to 199. We will see 440 new homes built here on green and lush land and to make access and egress manageable 199 will be replaced with a two lane double width swing bridge.

  9. Spray foam - applying to cold steel during winter

    in Boat Building & Maintenance

    Posted

    Hello,

     

    Is it a good idea to have spray foam insulation applied to cold steel or should this be left until the weather is warmer?

     

    I have a quote from Websters, job provisionally booked in for December, where they state that the steel surface must be dry and to ensure that sufficient dry heat can be provided (no gas heaters) to heat the boat in order to prevent condensation forming on the surface. Keeping the boat well ventilated while heating will help considerably.

     

    This suggests that I would need to hire a reasonably decent electric heater/blower. Obviously, I am not an expert and spray foaming is a first for me, but I would be interested to hear from those who have experienced this and provide any useful advice.

     

    Many thanks, I appreciate the help.

  12. Lister JP piston rings offset

    in Lister

    Thanks Steve

     

    I find that rather comforting, although I shall probably still put alternate gaps at 180 degrees. Any fraction of help in starting a new engine for the first time is welcome. After that, the rings can do what the hell they like

     

    Anyway, I enjoy the ritual, it reminds me to check I put all the rings in

     

    Richard

    Thanks for the responses, most interesting, entertaining and educational. I'll do as the manual states and stagger them, but evenly at 90 degrees and let the engine do the rest.

  13. Lister JP piston rings offset

    in Lister

    Posted

    Hello,

     

    According to the manual the piston rings are required to be staggered but it doesn't state what the offset should be. Given that there are four rings, 360 divided by 4 is 90; suggests that the offset should be 90 degrees between each piston ring gap. For example, bottom ring at 0, second ring at 90, third ring at 180 and fourth ring at 270, thus giving even distribution of the ring gaps.

     

    Is this logic correct or is there a more practicable answer?

     

    Thanks,

  17. Working a Swing Bridge alone.

    Nice sounding engine in the second boat, too bad you can only hear it when he's leaving.

    Peter.

    Thank you Peter, and for reference, the boat is a 58' Tim Tyler, and the engine is an industrial JP3, 'marinised' with a Paragon gearbox mounted at the back of the engine coupled via an R&D drive plate. I currently have the engine in bits while I make good the rather worn crankshaft, which I believe has been with the engine for the last 72 years.

  20. Leads/Liverpool from Wigan locks to Leads

    in General Boating

    Sorry but virtually all the many swing bridges between Gargrave and Bingley, plus a few beyond, have the pivot and therefore the controls on the non-towpath side. Note also that most farm bridges are not left open to the canal.

     

    There is at least one now though near Bingley that has duplicate controls via radio link to allow operation from towpath side, but this/these are still very much the exception.

    Which swing bridge has duplicate controls? I know that bridge 199 has a radio link with the controls sited on the towpath side. This upgrade was completed in March 2015.

    Regarding single handed swing bridge operation most if not all swing bridges have priority over road traffic, unless specifically stated at the control box.

    The key to single handing bridges is a rather long centre rope. Have a look at my YouTube video - search for micklththwaite.

    All the best to Iain and Elaine in their retirement. It is a shame that no other chandler matches their friendly customer care, support and most importantly, ability to supply parts (from stock) and to provide solutions.

     

    Thanks, you have been excellent over the past 19 years that I've been a customer.
