    Italian "Pronto Intervento"
    This little boat was found under a pile of junk in an old cluttered bicycle shop which sold toys on the side. Was looking for a part for my sons cycle in the early 80's when it was found. One of the two relatively ancient (mid 80's) brothers who owned the place said they had had it for years and would sell it for R5. It was made in Italy of polystyrene as a kids toy - obviously there was a motorised version at one time and it had a rubber prop on a fixed shaft plus the top lifted off with three screws. It was quickly converted using a small (180flat) motor, small Graupner rudder, Billings 2mm shaft with the rubber prop and oiler tube, 4 AA batteries and 27mhz Futaba RC for a motorcycle . It was used for years at the Johannesburg MBC as a have a go boat for kids. Very slow so quite safe with them . Fast forward 20 years whilst living in the UK - strip it down - Speed 300 motor running on 6 x 2/3AA Nimh cells through the same RC setup. Now frighteningly fast for its small size (+-13") it leaps up on the plane almost instantly and has to be run in very smooth water (picture taken in its old mode). The few kids at the club water in the New Forest all want to have a go - sadly have to decline as its much too much for them to handle........ Its name on the stern is Guesta Festa which is Italian slang for Party Pooper (from a friend) - as its a model of an Italian 'Customs Interception Launch'............
    Despatch No 9
    This is a Lindberg Diesel Tug - originally from Pyro - built in the early 1980's . A little modified from original - brass railings - cabin roof altered - external piping on funnel - winch from lighter flint wheel etc lifts off for shaft oiler - cover plate lifts off for rudder access etc. Its very seaworthy - being able to run in what could be termed hurricane weather at scale size. Very watertight . Runs on 5 cell AA Nicads for over an hour. Motor is a 7 pole out of a early PC printer. Tam-tech 27mhz RC - uses the original kit prop - reinforced with paper washing up type towel. (Once ran it in our flooded back garden in Southbourne as it only requires a couple of inches of water). Overpowered - as tugs should be - runs at hull speed limit but can push/pull boats many times its own size..........
    Model Products - Patrol Boat
    Built from a Rhodesian kit - kit produced for Model Products by a friend Mervyn Ward in Salisbury. Made from 'mugongo' a very light weight pale yellow somewhat dry dusty wood - meant as a replacement for balsa because of sanctions (looks like Jelutong but very much lighter in weight) Uses a 480 type Overland BB motor and a Graupner P30 prop with 4mm commercial propshaft. Much modified over the years - built in the 80's . Has sailed in France (Normandy,Brittany) UK (New Forest , Beale Park and a few other places)and many waters in SA. Currently under repair . Hull etc cribbed from Les Rowells Aerokits Patrol Boat but slightly different superstructure which lifts off entirely
    River Tug (Lumba?)
    This is my latest acquisition - unfortunately just started its journey and got as far as my sister near Southampton. Still many miles to go before it gets home. When that occurs will be doing a refurbishment.......... As a blog no doubt
    Darth Vader
    Bought from Maplins on a Christmas sale for a tenner including a reasonable 2 ch 27mhz radio (it sticks to one frequency) - cost was actually less than a spare set of batteries. Probably the fastest boat I have owned and probably the fastest at my old club. It has a strange underwater section - U shaped with deep triangular sections enclosing the U and a flexible 28mm 2 blade propeller - nick named Darth Vader by our newsletter/site editor the name stuck.

    Right Ian - highest price for a local magazine is about R95 - MB in the region of R150 if as you say - you could find one! Way beyond affordable. The PO is in a shambles as they have no funds - wanted a local PO Box long before lockdown - could not supply as there were no locks or keys - plus the fact half the box doors were rusted through or fallen off - no money for maintenance.......
    The staff here are good and do their best - but the problem stems from the top and a Govt more concerned with a dead airline.

    That cooling fan is not beyond your skills JB - hides the can pretty well - looking at a small computer fan as I write this - 2' diameter - sure you get even smaller............
    Good idea as you only see the top of the motor in a boat - not suitable for airboats though!

    Hi JB - Seems I missed a lot being away - You have moved on pretty far already. Looking great so far. What have you got in mind re extras - working bilge pump perhaps ? Not that you would need it hopefully . Or perhaps fishing rods , Tackle boxes etc . A replica motor would be nice - I have a V8 motor from a large truck kit given to me by a friend now in OZ. Always thought it would look good on an airboat model - but how would you stop the plastic from melting with the heat ? How did you overcome the problem on the other replica motors?

    πŸ“ Scratch built boats
    20 days ago by redpmg ( Commander)
    Flag
    The one good thing about kits is that usually apart from motors etc everything is in the box . Very useful when you live somewhere where its difficult to find MB bits & pieces. That said however you are simply one of many to build that particular model. Very boring to go down to the club and find a lot of the same boats on the water........ Not to say disappointing
    So my usual approach used to be to change a few things including the superstructure - unless that particular model had great appeal.......
    Fortunately now having stocked up fairly well with bits & pieces plus having use of a laser it was easy enough to revert to scratch building - my first ever boat aged around 9 or so was built from a photo and was probably quite crude by current standards - however it gave a lot of pleasure in building - and sailing in a garden pond but regrettably sank on its first real outing - giving me my first lesson in watertightness. Although my last few efforts for my grandchildren & lockdown are using a plan - the finished articles will have many deviations from the original - such as variable mast steps on the yachts.......

    Check the kitchen stores JB - there's a type of thin clear hard plastic cutting board which might be useful as the bottom slide material - has to be tough to withstand knife cuts on a continuous basis.

    Looking good Graham - wonder if you ever saw the rowboat populated by three skeletons - one of them doing the rowing. Never managed to get a close up look but believe the movement was made via clear nylon heavy fishing line - might that not work with your system ? - you would seem to be well qualified to devise something working on pull only. Might well be easier to conceal .

    This boat has now become a work of art......

    I should imagine most of us on this site are classified "At Risk" - the average age of the club in UK I belonged to must be over 70...........
    So I agree with Martin re the social distancing...........
    But some of the rules re not being able to visit an ill friend seem a bit harsh.
    The classic one here is recreational fishing is allowed - but you are not allowed to walk on a beach........
    So re-iterating Doug's statement - thank you Stephen for this platform allowing us to stay in touch with friends all over the world - and to make new ones.

    Martin - that's getting ridiculous - how can you even see what you are doing at that scale - you should be a specialist in micro surgery at a hospital - you really are incredible.

    JB that looks like a picture of an African Bush Baby - otherwise known as a Pookie. Everyone wanted one as a pet - until discovering not only were they nocturnal (hence the eyes) but as they lived in trees - and spent their time jumping from branch to branch - they peed on their hands before each jump - and if they were jumping onto your shoulder as they liked to do - well..........

    Well done Martin - so incredibly maneuverable - you will have to give her a run on bigger waters sometime - as long as you check water-tightness.........

    My little Lindberg Tug is not much larger and copes surprisingly easily with what would be "Hurricane" seas at scale - much better than a lot of bigger boats in fact - so as long as you fit a bit of poly foam flotation and make sure she is watertight there should be no trouble .

    Pity Im so far way or we could run them together............

    Hi Ron - alternatively to JBs suggestion you could try two other things . Use a 4mm Brass nut (assuming its a 4mm shaft) then file that to almost washer size - but ensure there's still a little bit of thread left - that will still work as a locknut - use a file BOTH sides to ensure that - there is also some stuff out there ( non-permanent threadlock ) which you can use in addition to keep the prop from falling off. Secondly file away the front face of the rear propshaft bearing - again to washer thickness - just enough to keep it from pushing into the tube . They are usually a very tight tapered fit in any event and unlikely to go further into the tube even if you filed of a little too much - assuming its a bronze/brass bearing. a nylon one can also be filed - but not as thin as metal.
    From experience I have removed the tip of a prop altogether for a similar reason (look at outboards) and its still a very fast little boat without much noticeable cavitation . However in this case agree with you that the blades themselves might pose a problem . I would personally remove the tip completely - leaving a flat face on the boss.
    Hope that helps

    Hi Doug - you need to get a portable O2 generator - but you would have to mask it too........

    Sorry to have missed this Martin - glad to see you progressing on yet another great build . Just shows you don't have to spend a fortune on something really interesting . You continue to be an inspiration to us all .

    I have often thought it must be awful to have spent hundreds of pounds on a kit - and then find there are at least another ten versions of it already sailing on your Club water...............

    Hi Rick - we do actually have a town here in SA by that name - sometimes known as Vishoek in Afrikaans - but more often by its proper name Fishhook . Its not at the end of the line - more like middle - Simonstown being the end ............. perhaps its like a long weight.........

    Hi Cash - we had a few for ours too - especially the FAF's - so also not able to post here.
    There was however a combined base in the Zambesi Valley called Mukumbura - its biggest claim to fame was having a Surf Club - being a long way from water - and temperatures over 40c on a cooler day........

    There is a book called The Boys Book of Model Boats by Gutenberg from much the same era. If you Google it - it is possible to download the book for free - also very interesting reading.
    Don't let the title put you off Nerys - its also from the age of Stereotypes and "Clever Lads"......

    If you looked on the RAF maps from WW2 you will notice two airfields - one Myarsi and the other Myelbow.........

    Funniest thing was everyone thought the names were from a local dialect.........

    Problem is Brian - the original engines were incredibly expensive to run - like the 3 x V12 motors in some of the MTB's/MGB's & most PT Boats. They were basically marinised versions of the Merlin/Griffin engines from Spitfires or more correctly modified Packards from Mustangs. (Rolls Royce motors modified by Packard). Would cost an absolute fortune even for a days run. Think in thousands of pounds not hundreds.

    We had some old Jet "warbirds" here for a while - at Cape Town airport - called Thunder City - a 20 minute ride in a Lightning would cost you about R40,000 (+- 10k gbp at the time) - they did not make a profit since the lightning guzzles +- 640 litres /minute - max duration being about 30 minutes. ( They have TWO Rolls Royce Avons like the ones fitted to the Hawker Hunters one above the other) Vampire T11s & Hunter T7s were much cheaper to fly in. Running 3 Packard v12's would be even more expensive.
    A friend has two Miami Crashboats from WW2 - without fitting Diesels he would never be able to afford to run them - he also has two Ford Class SDB's originally fitted with V16 Paxman Diesels - cost far too much to run as the Paxmans were two strokes - when fitted with the same size Detroit Diesels the fuel consumption almost halved - with not much power loss. He built an 82' steel hulled excursion boat based on the 63' Miami Hull - powered that with two Detroit V16's which at a lot less than half throttle push it along at about +-18 knots - estimated top speed around 30 knots when he has the chance to fit the right props & driveshafts - (perhaps this year as things are quiet) - at about 1/4 the consumption of the Packards - even then the fuel is measured in tons - not litres or gallons.......

    So the only way to fit original engines would be to accept that the boat would have to be placed in a museum and never run - which would be sad indeed.

    Money is always the problem and despite leaps forward in engineering techniques and the like you will probably find that the Waverley boiler refurbishment cost more the original ship did - even in updated currency values.........
