yes still clockwork,The best improvements have been made by lightening the motor, drilling holes in everything and replacing a side plate with one made of alloy.It is just a nut on the sponson, they are adjustable for incidence.It will now plane on the sponsons "unsticking" the hull.The original was built when I was 13/14,the motor came from the family gramophone when my dad converted it to autochanger/amplifier,the wood came from the woodshed but I was short of plywood and realised the back of my wardrobe was plywood and was hidden behind clothes so when my parents were out I cut the bits I needed from it!,my mates christened it "the wardrobe".Performance is down to propeller choice and is a compromise between speed and runtime.I took it to a boating pond in a nearby town when my wife needed to visit it and a council "jobsworth" told me I was not allowed to sail it,"only yachts and electric boats on here sir"no amount of reasoning would make him change his mind and he escorted me out of the park!.
Batteries!, always a problem in the 50s on "paper round" money, used to cadge,"borrow" or steal batteries for our boats.Used to be able to buy a cheap kit and even a cheap Japanese motor (coupled to the prop shaft with bicycle valve tubing) but it would be unused for weeks until I could afford a battery, and then they did not last long.Used to borrow batts from my dads bike lamps,my grannies gas stove lighter and the door bell!.Also use to be able to remove cells from the "winner 120" batteries from my dads sky queen radio as the HV cells used to discharge first.This was the downfall of glowplug motors,we could start them at home but on getting to the pool the tall 1.5v battery would be flat.My dad showed me how to locate good cells on duff car batteries by putting a load on them and measuring the voltage across each cell,we then emptied the acid out into mums washing up bowl and sawed the good cells out,refilling them with acid filtered through a handkerchief!,this worked a treat for starting glow motors but my hankie and the pocket I kept it in suffered!I eventually sorted the power problem by using a clockwork motor removed from the family gramamphone to fit an autochanger.
I visited Papplewick pumping station and found the day I had chosen was a "steam punk" day.They were sailing on the "lake" and had some really fine sailing boats, some live steam and some really fine "Jules Vern" boats and subs.I took lots of pics but found after I got home that the camera had corrupted the pics after I had shot a pic of a "Henry" vac that was cruising the lake,(it was not a real one just about half scale) The had stalls selling "steam punk" stuff but one stall had tools,and some nice boilers and steam motors.
There is no problem over collection,any time you wish,not able to private message you (I don`t know how!) better with a hammer than a keyboard!,phil. are you not interested in pipsteam66s boat,seems a very generous offer?.
Hi Dave,would £70 be ok?,I live at kelham near newark.This boat was used to tow a dinghy with me and my dad in it when mackerel fishing off Anglesey. Too many projects on,I underestimated the time available now retired!.
I have a queen I built in the 70s, a bit "tatty",fitted with an O&R 21,It has always been stored in the dry and is not soaked in oil,(engine compartment lined with epoxy)I could remove the engine and would sell it within your price range.The only problem is collection (I live in Nottinghamshire) and I am not prepared to send it as I have recently had several parcels destroyed by carriers.
Yes the Dubarry looks very similar and it says it was based on a thorneycroft.These were diagonally planked as were the full sized ones in the pics.Did not realise they were twin screw as they were afloat!.The chine hull was easier.The engine (A Westbury hybrid with bent pushrods!)is not very powerful but still gives more than scale speed.The bottom end is Westbury mated to an unknown top end,spark is by a car coil and 6v battery and allows a really slow tickover you can almost count the revs and a reliable pick up but seems to be flat out at 3500 rpm so with a bigish prop seems a good motor for the boat just wish I could stop it leaking oil!(crankcase pressure even with a 1/4" breather!)
Yes,I remember a gannet powered boat,used to gather quite a crowd.I left the area in 69 but sailed at lindow on visits back on the early 70s,by then I was on RCS reeds in an O and R powered sea queen and remember a chap sailing a large "flattie" powered by a honda motorcycle starter motor,it was amazing to see it floating "dead" in the water and then getting on "the plane" in less than a second!.
Lindow Common has been designated a Site of Special Scientific Interest (SSSI) and a Local Nature Reserve (LNR). Positive management is vital in the preservation and enhancement of heathland. In 2001, the former Macclesfield Borough Council received a special commendation from English Nature, the government-funded body which overseas nationally important wildlife sites, in recognition of its management of Lindow Common.So it used to provide enjoyment for hundreds if not thousands and now it is home to frogs and newts,you may walk your dog there but stick to the path,pick up after him and DON`T FEED THE DUCKS!.
No it as not fail safe,mine was just carrier wave so with contant signal gave full rudder one way and no signal gave the other.The whole system was a bit marginal and the Hill valve reciever needed two batteries and the servo another and any of them going flat meant trouble!After many crashes I returned to single channel and a rubber powered escapement!.Still remember the sparky as a quivering waste of time!.
Only had one button!as you said,once for right twice for left and once again for straight.Not galloping ghost,I flew that in a "sparky"it was sort of mechanical pulse proportional.Mine had a motorised wooden drum with a triangle of tinplate fastened to it so it reached around drum at one end and finished just short of the other.A moveable wiper slid along the drum so you could get anything from no signal to continuous.As you say the reciever relay pulsed a mighty midget against a spring.It had many problems,the battery drain was high,the thing was continualy twitching and if you flew out of range you got full rudder and a spin!Things are so different now,reliable gear at reasonable prices.But I still cannot remember how that throttle worked!.
I boat I used to sail at lindow,2.49cc frog and macgreggor single channel,I know it was "one push starboard,two pushes port" but how did I operate the throttle servo?It`s so long ago and the memory grows dim!,
Anyone used to sail at lindow common (wilmslow) in the 50s/60s ?,Now fenced off by the council but used to give much pleasure to boaters on sundays.Big scale liners,big sailboats with their owners wearing captains caps and carrying turning poles.early radio with transmitter on the ground,the circle at the end with tethered hydros (separated from the main pool by a floating barrage made from a washing line with "party four" cans attached to it).The ice cream van and picnics,hundreds of boaters and watchers.All gone now (a sssi!)
Hi Dave,sorry the problem with sponson lift is with a prop driven strimmer powered boat,it is always the same sponson that lifts and this is due to prop torque.As it is a "pickle fork" type boat I am going to make it asymetric putting the hull nearer the lifting sponson and move the fuel tank and radio battery from behind the motor to the front.I asked the question to see if anyone thought I may have trouble with my jet boat,(this is a mono hull).This is all my fault,I insist on fitting engines with far too much power into every thing!cars,motorbikes and boats,(I have bought a coventy climax fire pump to fit in my 11 foot sailing dinghy!).
Thanks Dave,no the dinghy had no torque reaction on a steady throttle just when the engine was "blipped".I started with a butterfly flap in the nozzle which worked ok,replaced that with a steerable tube beyond the nozzle which also worked ok and finally with the nozzle itself steerable mounted on a flexible pipe which did not work (the flexible pipe was far from flexible when full of water at pressure!).The question was because I have built a three point hydro with a strimmer engine which becomes two point due to torque,lifting one sponson as the throttle is opened.
Well you know how it is with ebay,"buy it now or make an offer" there was this hydro on,I watched it,no intention on buying it,I have far too many projects on anyway,the price is reduced,still no bids,a couple of mins to go,still no bids so make a very silly offer and gets it!It is powered by a JAP lawnmower engine and is huge.Must have been on reeds as there is a bit of an aquamite on it.Is fitted with coil/battery which makes it a bit nose heavy so will have to get the mag working.Picked it up from norfolk and it seems to be "norfolk engineering",even the props are home made
Too many other projects!,am going to fit a "butterfly" flap in the end of the tube for steering,(worked quite well in the dinghy) had planned to use a Merco 59 but will probably start with something smaller.Will the torque bank the boat on a steady throttle as with a "prop" boat ?
Jet boats can be a lot of fun,I live on a shallow river and converted an old sailing dinghy to jet drive using a "chonda"water pump.Interesting changing nozzle sizes and seeing the difference between volume and pressure.Have started converting a ply model using a normal prop with the OD turned to fit in an alloy tube and a glow motor.
Recreation of a boat built when I was 14/15 55 years ago,used a clockwork gramophone motor with the rudder couples to an eccentric on the spring box to make it sail in a lazy "S".the original lifted in the water but did not plane properly so seeing if 55 years later I have learned anything!.
