    Hi
    After spending all afternoon yesterday trying to fit the tank smoke unit into the puffer, it looks as if it's back to plan "A".
    I took the tank unit to pieces, the smoke part went under the wheelhouse and the blower in the bow's run some piping from the blower to the smoke unit, that worked but could not get the ESC and RX into the hull with out replacing the battery, moved the ESC & RX up higher onto a platform, could not fit the hatch cover, as I said it's back to plan "A" for now, I was never going to have smoke until some one said will it have smoke and no I will definitely will not be fitting lights.

    So yesterday (19/05/24) I fitted one of the seuthe smoke units into the puffer, it was so poor I think that I would have got more smoke out of a chocolate pipe than I got out of the unit, next I tried to fit the smoke unit from a heng long tank, it will work just to much work to get it to fit. so for now it looks as if it's a no smoke for this puffer.

    Hi One & All
    So the new battery has arrived and it fits, only thing is with my sausage fingers I just could not get it into the boat, I now have made a new motor mount and battery box so that it all now fits, also looks a lot better than before.

    Hi One & All
    when I started this build I tried to work out just were all the bits should go, one of was the battery, I had a 6 volt stick so I thought that this would be O.K, now that I have come to the point of test tank (bath) testing in went the battery, puffer into test tank, all O.K no leaks (good job I am not in Wales) so now would be a good time to test the motor out in water, Rudder working -checked, motor working- dead, all out of the water, the only other 6 volt battery I have is an SLA one, all worked fine with that so it looks as if the 6 volt stick is not up to the job,
    I do not have room for a 7.4 volt stick so what do I do now?
    As I was thinking it over I decided to have some fun with the T72 tank, then it hit me, (must take care when playing with the tank) the tank has a 7.4 battery would it be the right size? yes it was so out off the tank and into the Puffer, yes all works so new battery ordered.

    Hi
    First I will replay to Alessandro, you have got it all right my friend, and the problem is in the battery pack, it is just the wrong one in regards to mAH and age. If I take out the ESC and the rudder servo and connect the motor to the battery it works, add in the rudder and ESC the motor stops working.
    As for the motor that is one that I have in my New/old stock, I donโ€™t know if you have every done the old wash trick, the old method of bedding in the brushes on a brushed motor, stick them in a glass of water, connect to a 7.2V NiCd then stop when the water started to get blackened. This method kept the motor cool while washing the carbon off of the commutator as the brushes bedded in. Once ready just dry the motor off, put some oil on the bearings (bronze bushes) and give it a good spry with GT85 like WD40 but a lot better, no longer needed with brushless motors.

    LewZ my problem has all boiled down to using the wrong size of battery, the small liPo battery works just fine and the fit is perfect for this small model, after all it is only 17โ€ LOA, I just have to get my head around using LiPoโ€™s instead of SLA batteryโ€™s.

    Isaac yes I have ordered a small Lipo battery pack, in the mean time I am using the one out of the T72 tank to get all the parts in the right place, so far I have had to refit the battery box, and I am now going to remake the motor mount, should have done a better job in the first place.

    Rockbag As this started out as a winter build and only using items I have in the odds bin, it has taken longer than I had hoped, so far I have only had to buy a small stem winch and now the liPo battery pack, I think that in the future I will stick to my tugโ€™s as they are of a size that will take SLA batteryโ€™s, but saying that I still have the 1/24 size Puffer.

    Hi Fred,
    I finished building a Clyde Puffer a while ago and I power the motor with a 3cell 7.4 Lipo. This works very well. The speed controller needs to be compatible with the lipo which also provides power to the receiver.

    why not get LiPo batteries? They come in all sort of sizes and shapes to fit your boat.

    I have 3 large boats that have brushed motors as well as 3 brushless motored boats all running beautifully on 7.4 v LiPo batteries ( some are 3200 and others at 5000 MaH size ). Average run time is at least 30 minutes to an hour at my medium speed. I bring extra batteries when the measured voltage goes below 30%.

    Fred...

    Did you run the batteries through a battery checker (not just voltage meter)? The 6V ("stick"?) batteries should do the job unless the current (Amperage) is too low, the battery is weak, or you are drawing too much current in your boat.

    The T72 tank's 7.4V battery is probably a Lithium Ion battery. (I run RC tanks as well.) These are interchangeable with the 7.2V ion, Nicads, etc

    I recently got 10 of the 7.4V Lithium Ion batteries with the Tamiya (yuck) connectors; they are 3900Mah and very reasonable from China (where else could we get them). Started using them in my tanks and boats. They are about 1/3 the size of the 7.2V hobby batteries.

    I even made some adapters to fit the 7.4's LiIons in the 7.2V hobby batteries footprint, if needed. Bottom line is these should work for you if the boat has no other issues.

    Fred, I'm sorry but I didn't understand correctly.
    Bear with me, but it's a translation issue.

    So everything works except the brushed electric motor? Did I get it right?
    Precisely: does it work with a 6 volt SLA battery but not with a 6 volt battery stick? Did I get it right?
    Does it run on a 7.4 volt battery? Did I get it right?

    If you answered yes to the first questions then I think I have identified the problem, but before I tell you my opinion I have to ask you a few questions.

    The stick of 6 volt batteries that were unable to start the electric motor, are they alkaline batteries? What type of batteries are they?
    Are they four AA pens in series?
    Can you read the charge in Ah (Ampere-hour) or mAH (milliAmpere-hour) that is written on the batteries?

    How many Ah does the SLA battery have?

    Do you have any data on your engine? It would be important to know the voltage range, the rated working current in Amperes or the power in Watts.

    If you insert photos or videos it will all be much easier for me to understand.

    Maybe I didn't understand anything because there are words that I translated in an absurd way, but I'll tell you some things in general.
    If you already know them, don't worry.

    The brushed electric motor below a certain voltage (for example 3 volts) is not able to start even when idle (with a free shaft). Above a certain voltage, (for example 9 volts), it begins to be damaged.
    Within the working range, the more you increase the voltage, the faster it will spin.

    However, even with the correct voltage, if the power source does not have enough power the engine will not be able to start.
    We talk in terms of amperage instead of watts which is simpler. If the motor needs at least 1 amp and you are able to supply less, it will not be able to turn even if the voltage is the right one.
    To verify this you can do a very simple test if you have a DC benchtop power supply.
    Power a motor whose nominal voltage you know (for example 9 volts), you will see that it will absorb a certain current.
    Then leaving the voltage at 9 volts activates the current limiter. You will see that below a certain threshold the motor will no longer turn on even if powered at 9 volts.

    Hi One & All
    I have now fixed all the rope work on the puffer only took four hours, I now still have to find or make the hook, on the plans it shows the boom fixed to the front of the wheelhouse, but I went for the cross beams type of support.

    I thought it would be a good idea to have some form of working derrick, after looking at photos on the internet I decided to try making one,itโ€™s very crude and oversized, it works for me and looks right, the steam winch only moved the boom up & down and the same goes for the cargo hook, to get the cargo onto the quay the boom had to be moved by the ropes that are fixed to the boom and pulled by the dockyard staff,

    Hi One & All
    Now two months down the ling I think it is time for an update.
    Looking at the rudder, just how many ways are there to make a rudder work? For the Puffer that I am building, I feel that the control rod running over the deck will work fine for this boat. Now when I move onto the 1/24 Puffer then the rod over the deck is not the ideal route to go down, at 1/24 scale I will look at the chain route that means making some of the parts, or I will need to find the parts from an outside source.

    Hi Gary
    I do like the way that you have gone about rudder control on your Puffer, for my other Puffer, I was thinking of may be some form of tiller arm on the top of the rudder with the chains going around the deck to the wheel.
    Just love that you are a steam man.

    I also did not want a control rod running across the rear deck and my solution was this. Plus you could use a smaller servo this one is standard size, it works really well and fits in with the chain from the ships wheel. Regards, Gary.

    Hello Fred, if your boat manages to turn you will have achieved your result; there are a thousand ways of doing things, the important thing is that you remain satisfied, I believe.

    Hi Alessandro SPQR
    I am just updating the blog,
    the thing is having the control rod going over the deck on this model was the only way that I could see to make the rudder work, when I start on the 1/24 Puffer I will look at trying to have a working rudder that is like one that I have seen in a photo of a Puffer.
    There are some who are rivet counters that think that if you are going to make a scale model than it should be the same as the real thing, in my on or off years of model boat building I have come across one or two of them at some time.

    Quick update, I have now painted the hull, I used 1/8" pin stripe car tape to make the dividing line between the black and red of the hull, I also used 13a wire to make the piping from the fresh water tank to the galley.

    So far I this build is going better than I would have thought.
    I have now fitted a smoke stack to the galley, I made this from a drinking straw, and the deck hatch cover is tissue covered which I then used diluted PVA to give it that rippled look, I then painted it with a mix of cockpit green and satin black
