The saga of the leaking Clive Puffer Several friends had mention to me that the prop needed to be above the water line so out came stuffing box mounted motor higher so prop shaft above water line & replace shaft & prop shaft . While doing all this It donned on me like a light going off that the rubber shaft was lower than the water line & I think water was entering up rudder shaft . Photo shows area where water was when it was in water & the tube for the rudder shaft was below that so added more stern depth .Made up another rudder shaft that is higher & tube is also now higher.

    Chum444, is your "stuffing box" the size of the large diameter tube under the large filler and the rest of the shaft slips into the shaft tube? If so, the sealing area seems kind of small.

    My preference is to have a fairly large sealing area. For example, using the attached drawing, the two ends where the shaft slip fits into are each about 5/8 inch long leaving a long void between the shaft OD and the tube's ID. [EDITED: this area is filled with the sealant lube.] Thus I have no problem with leakage when the entire shaft is below the waterline.

    Also... as you can see in the photo, the prop shaft is horizontal and sits about 2 inches (50mm) below the waterline. No leaks if you make the stuffing box long enough and use the right sealant lube.

Aucklands' classic wooden boat festival ,1,2,3 March
Was invited to take my restored 1970s 12ft racing yacht (red and white one-93 at 1:3) down to put in the display this afternoon, at the Viaduct Event Center In Auckland, and decided to get some pics of the boats on and off water before the crowds come over the next 3 days. Lots of beautiful restored yachts and launches, as well as smaller racing and sailing dinghies. A couple of NZ designed and built Chris Craft copies inside as well. Also steam launches and a few models.

The boat at 1:54 and 3:12 does not have the usual V8 as you would expect, but has a 4 cyl Mercruiser motor, not as the drive motor, but as a generator running 3 high output alternators powering an electrical system for twin electric motors, (round black objects seen in pic, in front of petrol motor). Shafts run each side of petrol motor, Has large control boards on each side for each motor. Boat and laminated wooden trailer designed and built by the owner, Took 2000hrs to build,- absolutely immaculate workmanship.
Also a short vid on an Auckland ferry trip I took while waiting for the liner Queen Victoria to
depart

Changed motor in St. Pierre Dory
I like the new motor, it has a higher voltage rating than the Graupner 400 which is 6 volts.

    Hi good idea, have you been out on the water yet?

    I have several 12 -18 volt motors the size of a 550 and run them on 6 -7.2 volts and they will turn over a big prop 45 - 50 mm.

    This looks good on a cargo ship where you can almost watch the prop turn over. They do not get hot and have a low current drain. Bonus is they are often cheap! Also I can use slightly cheaper NiMh batteries of about 3300mAhs.

    I have a few Pittman motors originally scrounged out of computer tape decks 40 years ago. They are almost silent and work really well.

    I always check for hot batteries or motors as I do not want current diverted from the motor to heating up the drive train.

    Following a friend I have also found a cheap and effective and silent U/J. It is plastic flexible tubing about 3/8ths inch diameter in less than 2 inch lengths.

    You can use it in place of the Huco U/J, keeping the brass inserts on which it is a tight fit. Or if you have a threaded shaft a largish pair of nuts locked together with the tubing forced over them.

    They need to be in a straight line and a few fast forward and reverses settles the tubing into position. The drive is silent and efficient and good for up to 20 watts or so.

    I would agree with others, viz. use a smaller prop. When a motor gets hot it normally indicates too high a resistance from the prop, so try a couple of smaller sizes and monitor its performance.
    Good luck😉

Launch of St.Pierre Dory
Today, as the temperature rose to nearly 90F/31C the St.Pierre Dory was launched at Balsam Lake Provincial Park. Water was pleasantly calm. My grandson handled the controls while myself and Grandma took pictures to document the event.

Very pleased with how well it performed. It is very sea worthy even riding the swells left by passing full-size runabouts.

The only issue was the motor was extremely hot to the touch. This could be caused from the wrong prop.

    Ronald, the prop is actually 1-3/4" ... in the photo you hav indexed the left blade to the end of your ruler, not the "0" point on the ruler. My 33" PT109 calls for a single 1" plastic prop to reach scale speed. I think you need a smaller diameter & much less pitch to alleviate your motor heating issue. Heatsinking, & watercooling or a fan will not fix your issue.

    She certainly handles well in the water. That would be a nice one to enjoy cruising around with. From the video it looks like the velocity is more of a speed boat rather than a dory.
    Nice job!

Miss Katherine from Mahone Bay scrap yard to Barry’s Bay
Miss Katherine runs very well though the geared motor linkage is a bit noisy, needed some grease.

Here is the real Miss Katherine as you will find her today should you visit Mahone Bay, Nova Scotia. She has been in the boat yard for over 15 years.

It was from these photos that the model was created by me.

Just a fun project to use up some old radio gear , single for steering only, or two channel if you want to include a sail winch.
Great for when the pond is full of weed - Also if no wind , stick a motor on the front or back !.
Just have fun !

Russian Sun Aluka
Built from old kit. I built one before and the Bluefin one too from Dumas. I cut the hull separation so a space is there. In general it was fun. I had to buy an older Rc as only 72 MHz works under water for maybe 3 ft. The ghz signal works surface only. I cut out all the hull flooding holes as per pictures I gathered. Basically built as per blueprints inside except used newer motor controller that can take LiPo batteries. Excuse the messy background.

    Like your sub!! We have several sub guys in our club, at least one of them uses 2.4. He runs an extension for his antenna up the sail (conning tower) and hides it in either the periscope or antenna. His boats are static divers, but he stays at periscope depth when he submerges. The boats set up to blow ballast and full up planes if he loses contact. Not trying to criticize anything you’re doing, just letting you know 2.4 is doable with restrictions. Most of the ponds here in North Texas are too murky for much below periscope depth anyway.
    Anyway, good luck with your sub! Let me know how it turns out.

    I had thought of a float with antenna but in he end use a MHz transmitter was easier. I had sold all mine so I picked up one from eBay. Actually I wound up with two one AM one FM. FM worked better. The dc motor controller was from a car as it had reverse capability plus switchable micas or LiPo. The Ghz band gets water attenuation so it won’t work under water well. Bathtub test showed at least a few feet under was ok. Only thing o don’t like is you seal electronics so it has to be really tested. Battery is on a plastic box like that can open fir access but I put a soda bottle cap structure to access charge connector anyway it’s fun

Camera Boat No. 5
Camera Boat 5 uses another simple "pontoon" design with 90
rotating motor and fan unit with rudder which was added later. Gopro was mounted on rotating servo which gives 360
vision.
Camera operated with phone using Gopro App.
Regarding filming techniques etc. - Still plenty of issues to improve and overcome along the learning curve !.

Mni Tnx Graham for being there with "Bill & Ben" and Jon G7NFK for all your previous help and support since my stroke.

Sterling Lumba is looking better!
Here's a few pics of the Lumba. It is ready for fiberglass and the superstructure is here just test fit. I need suggestions on how to power it; I want it to move scale, about 20 knots and it is going to be twin screw. I have a pair of 800 motors that are great but might be too much, even though I would rather this be over-powered than under. She has very cool lines, like an airplane. Lots of curves and twists all over her. She's a big girl, ready to carry quite a few angry oil rig employees on a dark and stormy night.

Motor Barge "Nellie" - visits Buxton
Information from Nerys -

In the 1940s and 50s, many traditional Thames Sailing barges were converted into motor barges. This is a model, based on photos and my memory of the 'Nellie'. The sailing barge 'Nellie' was built by Cremers at Hollowshore, Faversham in 1901,. She traded under sail carrying about 90 tons of cargo around the Thames, Medway and Swale until about 1952 and then had the gear taken out, a Chrysler Crown petrol/paraffin motor installed and carried on trading for some years owned by R.Lapthorne & Co of Hoo on the River Medway.. She was eventually sold out of trade and is now privately owned. She has been rerigged with a reduced sailing barge rig without a topsail. My model is based on a 30" barge hull from Dave Watts Mastman.

NOTE More information from Nerys - read on ........

Hi Phil,
I'll just add a little more information to that. I was Nellie's skipper in the mid 50's for a few years. We were based at Hoo on the Medway and carried cargoes around the Medway, Swale, Thames and Colne. Regular trips were such as ballast from Fingringhoe on the Colne to Hoo, sand from Upnor on the Medway to the Ford works at Dagenham, fertilizers from London to Faversham and Queenborough, wheat from London docks to Whitstable and more or less anything that could be carried between ships in the London docks to anywhere in the Estuary. We were paid by the freight. Half the value of the carriage charges going to the owners and the other half to the crew, shared 2/3 for the skipper, 1/3 for the mate, Then fuel and other expenses were divided up similarly.
Nellie, of all the barges I served on was the one I liked best. She was the smallest, but there was just something about her. However as a footnote, in the 1970's I built a forty three foot schooner rigged barge yacht in the same yard as Nellie was built.

    Yes, Nellie visited Buxton. We had been on holiday in the Lake District and on the way home, made a diversion into Buxton. We were made most welcome by the members we met and particularly by Phil and Graham. Enjoyed a nice little sail with Nellie. Made a pleasant interlude in an otherwise long 300 mile drive.

    Cheers, Nerys

ANOTHER GO AT A LAUNCHING VIDEO
Thought I'd try for another vid to try and improve on the previous efforts. Had another still day and good tide, so went down to the estuary again. Bit of a mission again,- competing with a few 100% boats and the steep slippery ramp. Truck didn't do a lot better than the jeep, and it weighs about twice as much and has a 4x4 rear, but at least it managed to get the boat out of the water. Forgot to take a 2s for the thermostatic fan for the truck motor, so it got a bit hot and faded towards the end. A lot of work for a 550 geared motor !

Still getting used to the new editor so the vid's a bit scrappy. Almost impossible on a weekend to find the right space with no people, but there is not a lot of choice without going for miles. Fun trying to drive 2 vehicles,- truck doesn't have a handbrake like the jeep, so a bit tricky backing down the ramp. Whole outfit is 1.5m long, and weighs around 12kg.

    Hi JB,

    I’d be happy to come and be your assistant, provided you could afford my airfare 😂

    It would be possible, I think, to operate both models from one Tx by adding some custom electronics to each model. This would need to operate like an RC switch controlled from a spare channel. One one model, the ‘switch’ would connect the servos and ESC to the Rx whilst at the same time on the other model, a switch would disconnect the servos and ESC. Operating the spare channel would reverse the state of the switches to allow the other model to be controlled.
