Russian KC100D waterjet work boat project

A bit more internal work done, - dash made, steering wheel, helm seat and wheelhouse 'carpet'. Outside,- bow bollard, brass 'roof rack' bar on rear of cabin (for spotlight, radar, siren) and spotlight (from plastic tube and PVC with brass support). More lights wiring and internal floors etc to go, but getting closer to launching. Haven't had a reply (re the dual light colours) from the Russian guys, - maybe they are 'visiting' Ukraine on a compulsory holiday.😐

Russian K100D waterjet work boat project

Just having a play with an idea for a model of a early Russian KS 100D general purpose work boat. These were used for river work towing logs etc in shallow rivers . The water jet is unusual, as it has a rear shute with twin rudder type deflectors, and rear hull side ports for reverse (independent controls for each port). Someone on the site mentioned a steam powered water pump driven ship from the 1800s ? a while back on the site which used a similar principal. The boats were made by the Yaroslavl shipyard, and were very common in the late 50s till (I think) the 70s. Not much info on them but a few guys have rebuilt old ones for pleasure boats. They have a speed of around 16-18knts and used a Yamz 170hp V8 diesel. I've contacted (YT) a guy who has rebuilt one of these boats, and he has fitted the V6 version of this engine. My attempt is not like the original, as there is no info on the complicated internal deflector system, so I've gone with the next best thing using modified electrical conduit fittings with flap valves. Seems to work ok, but not sealed yet so leaks like a sieve. I'd use a 26mm jet unit for the pump in front of the unit. I'll have to reduce the diameter of the side outlets to get more force behind the jets. Might have to fit the unit in a waterproof tray with a bilge pump. as I think, even though it will be sealed, it will still leak slightly round the 3 shafts. https://youtu.be/7Lgb7hH6ln8 https://www.youtube.com/watch?v=altwiMdZlIA https://www.youtube.com/watch?v=yWSI8moMeZg&t=33s https://www.youtube.com/watch?v=87PsJVdPNhE https://www.youtube.com/watch?v=CQ3U7XmeG1A (similar later model showing manoeuvrability) https://www.youtube.com/watch?v=hblw4_44FB8 The big lid on the jet is for clearing weed or similar which might get into the unit.

Hi JB I agree with most of your comments with one exception. Any puffiness in a LiPo cell indicates misuse and irreversible damage to internal components resulting in the release of gases into the sealed cell. Putting in the fridge will cool the gas which will contract in volume and may appear to repair the problem - it won't. On re-use the battery will heat up and puff up and eventually split the seal and self destruct when the air reaches the internal components and results in a chain reaction. The most serious types of misuse are: overcharging by a very small amount (0.1v) which can be avoided by using a balanced charger set to the correct battery type, number of cells and capacity; discharging below the safe voltage, typically 3.5v per cell. A LiPo safe ESC will allow you to set this voltage so that reduced power is enabled allowing safe return to shore; not discharging to the storage voltage (3.7v per cell) if not using for any length of time (1+ weeks); common sense as you describe cover the other issues and I would add do not or charge or use the battery if it is too hot to touch. I agree entirely with your last para. dave976

7th Dec: The pipes that run along the keel of a boat to provide cooling for the engine are called what? A. Keel Coolers (81%) - Correct Answer B. Underside Duct (5%) C. Chilly Bottom (2%) D. Thermal Bypass (12%) A keel cooler is a closed-circuit cooling system mounted externally on the vessel's hull below the waterline. The concept of keel cooling is similar to the application of a radiator on a car. Engine coolant is circulated through the keel cooler, which transfers heat from the coolant before it returns to the engine. Most people got it correct 👍 Stephen

An easy safety box to make, is a cheap metal tool box. Mine is lined with plaster board covered with glass cloth. There is a vent hole in the top of the box with glass cloth to retard flames (glass cloth will withstand a gas flame without burning so should slow down a LiPo flame for a period of time ) The box is not locked when in use and the lid is left sitting to avoid gas build-up in the event of a fire. A good idea with LiPos is to monitor them constantly and ALWAYS balance charge. If you see 1 cell going over the 4.2V max (can happen even with good chargers) and the others are around 4.16/.18/.19, stop the charger and put the batteries on a separate balancer until they even out, then it should be good to use, even though the voltage is a bit less. As long as your battery is not too puffed, (a small amount of softness after a large draw is ok - you can put it in the fridge/ chilly bin for a few minutes if they are warm, and it will usually return to normal. If they puff a big amount and stay that way, get rid of them. Discharge them in a bucket of really salty water for a week until they stop bubbling at the terminals. I usually cut the balance and main leads off before I do (outside, one wire at a time, making really sure you don't short anything) to use later. Once the battery is discharged, take it out to the middle of the lawn and put a large nail or garden fork right through it and leave it for a while, to make sure it's well and truly dead before disposing of it . I have LiPos I'm still using from 2011. If you treat them well they can last for years (buy good quality batteries like Hyperion or similar, cheap ones can be dangerous.) You might pay a bit more but they should last a long time. Balance charge them, don't over draw them , don't drop them, don't have sharp objects (modelling knives etc) round them on the bench, discharge them to storage after use, don't leave them in the hot sun, and NEVER short them, and they will be good for years. Nothing special,- just common sense. If you are scared of LiPos, try (DON'T) shorting a fully charged car battery and see what happens, be sure to wear an acid proof full suit, respirator and have a decontamination shower handy 😮💥 All batteries are dangerous even NiMH and NiCad's which can cause fires if shorted or go bang.

Frederick Mistral (aka "Duna)

Here is my partial build model of the Frederick Mistral. The kit was made by Anfora and for some reason they call it "Duna". What stopped me from continuing was the rudder control. This was via a chain that ran on both sides of the deck just inside the gunwale. This ran from the pilot house back to a cam like arm on the rudder post. there were a series of pulleys along the inside of the gunwale to keep the chain in place. My problem was that I could not find a small chain that could withstand the tension. I made a lot of corrections/modifications to it following photos of the real tug. This included many new/replacement parts that I had 3D printed by Shapeways. They are shown in the last three photos. This is an interest tug *(the historic original is still floating on the Danube River) and I wish I could finish it. Lew

There are several alternate batteries available. LiPo has the best power density and the lightest weight. For fast models LiPo is my choice. For slower and heavier vessels, such as tugs and merchant ships, there are more appropriate choices.

Slightly off topic, but I was reading an article on I think the BBC web site about the number of fires at waste recycling plants. In some cases the factories were burnt down. The authorities can't be 100% certain but they believe most of them were caused by batteries in disposable items ( musical birthday cards and toys etc.) and batteries thrown away. There is a video from a security camera of an explosion on a conveyor belt. All batteries should be disposed of at an appropriate place. I was repairing my grandson's drone when I accidentally shorted it out. The small flat LiPo immediately puffed up into a barrel shape. Fortunately it didn't explode. Best wishes Tim

Here is a small delicate Model Shipways Dory kit that I added a sail rig with rudder. The kit has small laser cut parts which if you are careful removing them, the parts do not break, but it does if pressure is applied. This small kit’s wood is delicate and light weight so go slowly. The instructions were very clear, it said to use CA but I used a good quality carpentry glue and small clamps. Some parts of the instructions asked for beveled edges, but frankly the material is so small and delicate that I ignored it. On a larger model sure, but not on this one. The dory will be painted in the Spring when it is warmer weather, it’s winter in Canada. I referred to John Gardener’s The Dory Book as a reference for the rudder and sailing rig.

A Trip to Windermere Boat Museum

Something I thought was good about the Windermere museum was the fact that one could borrow, presumably for a fee, a simple pond yacht to sail on their pond. They sold them of course, I think they were £50. Lots of interesting boats in the museum, well worth a visit, let's face it, what tourist attraction is cheap these days. Cheers, Nerys.

Hi Nick d charging your batteries in a fireproof container will restrict the contents of the battery spreading to other combustible materials if it catches fire have a look at the photos on my previous message. My friend and l consider ourselves very lucky we both discovered the blazing batteries before it turned into something more serious. He now always charges any battery without it safely placed into a fire resistant container. Good luck and stay safe. Jim.

Prefer place them in a container. I use a ceramic made fir it but see a bag like thing as well as surplus ammo boxes. If the battery is puffed up it’s no good. Google How to get rid of it. So far no house fires but dark spot like in the pic still in concrete floor. I use 1 to 3 cells about 2 amp batteries. All batteries are labeled with Marker pen. I’m usually around when charging. In summer do it in driveway.

Would agree it’s not cheap but your £9 entry fee gives you a ticket that you can use for a year. Take into account that you don’t have to pay for parking if you visit the museum or use the cafe then it’s not too bad. It is a fascinating place to visit, well worth attending the conservation talks which take place daily (I think).
