    Fire Monitors Part 1
    The white metal items supplied are OK but really donโ€˜t lend themselves to being working items. Graham93 has already completed a
    version
    which looks just like the drawing and photos available, and are the best Iโ€™ve seen. The bar has been set so here goes, whenever an item like this is been contemplated itโ€™s always good to spend some time in planning a sequence of operations and assessing the problem areaโ€™s at the start of the work and if possible dealing with these parts first. Failure of the difficult process doesnโ€™t mean you have wasted work on other parts that are now scrap. I think the most difficult and problematic piece is the pipework that sits at the top and curves round in two halves, this in reality is a casting, however replicating it can be done using brass pipe. Brass pipe can be purchased in annealed form; however my stock wasnโ€™t so the first job was to anneal the tube. Heating to a dull red heat and allowed to cool, this treatment will soften the metal completely. In some books it is suggested that the brass should be quenched in water (which is what I do) after heating but this is to speed up the commercial process, and quenching has no effect on the annealing process. So tube annealed we need some method of retaining its tubular form during bending, in plumbing I use a spring but when you compare wall thickness/dia a spring would have to be mighty strong and so small. An easy alternative is to crimp one end of the tube and put some soldering flux down the tube, follow this by heating with a low temperature blow torch to melt solder and fill the tube, then allow to cool. You now have a soft tube which when bent will hold its shape. Thatโ€™s the next challenge, the shape, and being able to replicate it twice, so an easy jig is required. Having marked out a scrap piece of hardwood I cut the โ€œUโ€ shape using the band saw and filled a groove along the top edge, this was then placed under my drill press with the appropriate dia bar (this must be calculated accurately as it helps to create the final form) on top of the tube, then just pull gently down (it takes very little force) this jig leave a small amount to finish bend to a complete a circle, the excess length is trimmed off and then I used a piece of hard wood with a small radius on the end to tap the final curve. Next the circle needs to be cut into two pieces I used a small slitting saw in the milling machine. Now itโ€™s time to remove the solder, simply heat up holding in plyers and then shake vigorously to expel the solder. (Make sure you do this on your own and wear safety glasses.) The white metal โ€œmain pillar fittingโ€ and the monitors final โ€œexit pipeโ€ will be used in the unit and all that is required is to mount them in the lathe and drill a 4mm hole through each and clean up the casting. Next I cut 4 pieces of 4mm brass pipe; these will form the main water passage. Two more machine turned items are the โ€œpivot post topโ€ that feeds water through the 2 brass pipes into the โ€œjunction blockโ€ which then feeds into the exit pipe, sounds all very simple? Having made all the components, itโ€™s time to think about fastening them all together. First items to be joined are the โ€œupstand pipeโ€ to the โ€œpivot post topโ€ X 2 also the โ€œfeed to exit pipeโ€ and the โ€œjunction blockโ€ X 2, these four joints are all to be silver soldered. I mounted them in a piece of wood and placed a tight spring brass ring around the upright pipe to stop then sliding down when heated. Having the joints spotlessly clean is paramount, the flux is added, I insert very small pieces of silver solder into the holes at the top cross holes (less is more) a gentle heat, and watch as the flux goes โ€œglassyโ€, this is closely followed by the solder melting, watching at the lowest point of the joint for the tell-tale shinny liquid metal. No fettling is required so the 4 parts are dipped for 45 minutes in masonry brick cleaner (dilute hydrochloric acid) the parts are now clean and ready for the next soldering activity. See part 2

    Re - Are the shafts ball bearing at both ends? and canโ€™t you get sealed bearings Hi Mike, they have dual bearings which are MF 74 flanged bearings - 4x7-(8.2)x2.5 - steel double shielded, so are quite small, and are a tight fit in the brass tube so I don't want to disturb them until I need to.

    Wiring help needed.
    Evening Commander (๐Ÿ˜‰) First the 6V loads- What you need is a 6V voltage regulator tacked on to the 12V supply. Simplest way is a 3 pin IC regulator (looks like a power transistor๐Ÿ˜‰) from the L78xx series. The xx stands for the output voltage, so here L or LM or MC 7806. Thing to watch for when buying is their current capability, most are only 1Amp. There are some around for 1.5A or even 3A. Check your usual component supplier, or Google around (don't let Caroline catch you ๐Ÿ˜‰) Attached is a datasheet for a 1.5A
    version
    . Fig. 3. shows how to wire it into yout 12V supply. Don't worry about the capacitors. They are intended for mains derived supplies to suppress voltage transients on the input, which you won't get from a battery. The cap on the output is to suppress transients from the load when you switch it on. Not worth worrying about if the thruster motor is small. But if you happen to have a 0.1uF (100nF or 104 code often printed on the ceramic) ceramic plate cap kicking about ... NOT an electrolytic can type!๐Ÿ’ฅ https://www.google.com/search?q=0.1uf+capacitor&client=firefox-b-d&tbm=isch&source=iu&ictx=1&fir=aT8JdfspcXDrEM%253A%252CkimvVilj_2DqfM%252C_&vet=1&usg=AI4_-kQAb-VMPkepdmZJ-2Vd36rwOQKpWA&sa=X&ved=2ahUKEwiKpbOmxqbkAhVIYVAKHTOBC80Q9QEwDHoECAcQHA#imgrc=aT8JdfspcXDrEM: Bow thruster- Just use a small ESC same as for propulsion.๐Ÿ˜Š What current does the thruster motor draw? Radar motor won't drink a lot I would think. Mine (converted servo) runs on a D size 1.5V dry cell for months! I don't bother with an RC switch for radar, just switch on (by inserting the battery!๐Ÿ˜Š) at launching. Cheap n cheerful but woiks! BTW; if you want to turn on the proverbial sixpence (that's dime for our colonial brothers๐Ÿ˜) fit a stern thruster as well, wire it's motor back to front and feed it from the same ESC via a Y cable. Don't disappear down your own funnel though ๐Ÿ˜ฎ๐Ÿ˜ฎ Another way is a so called Universal BEC. This supplies power to the RX and connected loads. Some can cope with up to 5A. Google UBEC. Minor snag is that all the ones I've seen so far are 5V! Might be enough ? If you go this way disconnect ALL red power leads in the cables from ESCs to RX IF they have BECs, or they'll fight each other! Cheers, Doug ๐Ÿ˜Ž BTW How's your Commander Commander?

    40'' Seaplane Tender, new build Z-1
    Didn't quite make it by Z but what the hell. Thought I'd throw a small bit of progress in as there seems to be a bit of a building lull lately. Made the rear wheelhouse partition and 'louvre' door, and 4 cleats, which I think look too small (ran out larger of brass rod) but are made with the vertical stem going through the washer as a pin, and are not yet glued in. Finished the rear cockpit trimming and internal water diverting coamings, and done one side of the boot topping to try and tidy up the waterline, (the masking tape all seems to be crap and bleeds - unless you want to spend $18 for 'professional' stuff which is probably just as bad!) Hard to find thin trimming tape these days as well, so have to cut your own to go round tight curves. Used to use thin dope to seal the edges years ago (on coloured doped aircraft) but will melt the acrylic and leave a raised edge, which I won't be painting up to. You have to do a number of really light coats if you want to stop it bleeding, and run a blunt tool along the edge really firmly beforehand (still not good enough really). Could have used pin-striping tape but that leaves a raised stripe (scale waterline would be about 1"thick) also $15 a roll with 90% left over (bit of a waste). I also roughly superimposed the model on the original photo to see how it compared. The original is a late model MK 1 narrow hull, but I went with the Mk 2 41'6"
    version
    with the longer wider hull (to have more internal room to play with) but with the coamings, masts etc of the original. The MK 2 has a more pronounced 'Clipper' bow with more flare and is wider 'midships' but the wheelhouse is pretty similar. There ain't no one to worry about the accuracy these days as there are few good photos of the original (pretty well just mine and a friends fuzzy super 8 captures) so it's just a rough crack at it (also using a bit of the old 'poetic license'). Will email a pic to the current owner when I've finished and see what he thinks. Just have dash and wheel to do now (I think - bound to have missed something) Oh, that's right, - the rear cockpit canvas and dinghy! (I knew that๐Ÿ˜)

    Re: 40'' Seaplane Tender, new build U
    Hi MT, sound units are actually for cars but have a choice of 58 sounds from V8s to diesels and are the only ones I've seen which seem to sound ok. You have to go through all the sounds and try them through the throttle range but there are a number which sound ok for boats. You can also plug them into your computer and make a few changes such as throttle sensitivity, turbo sound and volume etc. The sounds are proportional, from starting to full throttle and are all WAV sounds which seem to be split up into small 'samples' and as such, some are not quite linear but are useable. There are 2 different models, One is the 'GT Power' sound and lights model -
    version
    2 (the better I think) which comes with all the pre wired and plugged LEDs needed for a car, (h/l, t/l, indicators etc) and comes as a module and separate speaker, (you can plug 2 speakers into this module for better sound). The other model is the 'GT Power' Car Engine Sound 'mini' which is just the sound module and speaker in one box. This works the same as the

    2, and around $ 51 for the 'Mini'
    version
    which is comparable to most other sound units available, but with more features than some. Apparently, if you send the GT Power tech/help guy a complete WAV sound file (ie, start, idle, and steady slow acceleration to full and back they will make a sound file for your unit and email it back to you,(yet to try but would be brilliant if true) Units are sold on Ebay, Ali Express and Banggood (and many other model shops) and it's worth shopping around all of them, as there are big price differences. These are also sold as GOOL RC sound units but are made by GT Power. ( http://www.gt-rc.com/en/msgBoard.jsp ) You will see the home page on there. I use a number of their products such as battery chargers, rev counters, battery checkers etc and all seem very reliable and work well. I don't think they sell direct, but they are sold everywhere. For Rooky Sailors benefit, the motors are Gool RC 540-45T 7.4V brushed car motors which have ball bearings and replaceable brushes (motor is rebuildable). Haven't tried them on the water yet, but the 45T (12000rpm) should be tourqy enough (different turn Nos are available) John B

    You can create the element, or Icon (also known as "Shapes" in some programs), by grouping the vector objects. It can then be easily moved around in one lump ๐Ÿ˜‰ When I have the object I group it, write the Part name/
    version
    into a box then group that with the object. If you have the Element, Icon Shape (whatever!) sidebar open you can copy your new "thing" straight into it for future use / reference. The program then stores the shapes associated with that particular drawing or drawings where they are used. Separate shapes files are created which enables their use in new drawings. Sets of particular types of shapes can thus be created. You'll be amazed how soon you have a comprehensive library ๐Ÿ˜Š Of course you can use all the normal aspect, scaling, modification functions as usual when you add a basic shape to a new drawing. Update the label and away you go again!

The advantage of doing it on CAD is that there is little need to prove the drawings - if it fits on the screen it will fit in real life. Ideally, I should learn 3-D cad and then I can virtually assemble and look at clearances without any need to cut materials at all...

    Magnetic motors
    Hi Martin, "This type of motor would be good if you could control the speed." Since the motor uses permanent magnets on both stator and rotor the speed will also be permanent and unalterable, as both magnetic fields are constant. To alter the speed of the vessel (or go astern!) you would need to alter the pitch of the prop and hence the thrust. 'Variable pitch propellers!' This is the operating principle of constant speed turbo-prop aero engines for example. VP props are also used on many ships these days. Needs some intricate gearing built into the prop hub, and controlled by !? ๐Ÿค” Control shaft running inside a hollow prop shaft? Don't know of any model

    Turnigy A-6-10 200W Balance charger & discharger
    Hi Michael, I had to make up adaptor leads as well for my bigger NiMhs; one for Tamiya and one for XT60s. The third pin on the socket has no connection. The manufacturer of these gizmos seems to assume that they will only be used for RX batteries!๐Ÿค” "These batteries will be used in parallel so can they go through this discharge/charge process linked together? " If you mean all connected in parallel - I'm afraid not๐Ÿค” The charger controller would get awfully confused! As it has to be able to read the individual pack voltages in order to control the process and know when to stop discharging and start charging. To cycle both batteries simultaneously you need a two port charger. Something like the one in attached pic. I also recently acquired a Graupner Polaron EX two port charger. https://www.graupner.com/Polaron-EX-charger-red/S2011.R/ More expensive (a lot!) but it can also do a lot more for your battery management. You can programme and store several different types and capacities of batteries; SLA, NiMh, LiPo, LiFe etc and set all necessary parameters; number of cycles, discharge current, charge current, stop criteria, timer etc. A selectable tabular or graphic display shows you how the cycle is progressing and the status of the battery. It will also tell you the internal resistance of the battery to give you an idea of it's quality and suitability for high current applications๐Ÿ˜‰ Does LiPos and SLAs as well. I just bought the two port DC only

    without mains input cos I already had a 13.8V 17A supply kicking about doin' nowt! You can also hang the charger on a 12V SLa or car battery.

    Batteries in a DX5e
    Hi Martin, Save your money, time and effort! Just like my DX6 your TX needs 6V from Alkaline batteries. To get 6V from NiMH you'll need 5 cells, which you haven't got a cat in hells chance of squishing in. A fully charged 4 cell pack may show up to around 5.6V OFF LOAD. So you start around half a volt short in the first place. Shortly after a load is applied the cell voltages will drop to their nominal 1.2V. Giving 4.8V for the TX. This is roughly the voltage of 4 nearly flat alkaline cells. 2000mAH cells have been recommended. Good quality Alkaline cells made to the IEC standard, such as Varta or Duracell, have a capacity of around 2500mAH. Make sure you get the Heavy Duty
    version
    , i.e. for cameras. These will last for ages, unless you forget to turn it off ๐Ÿ˜‰ When I tested your TX the switch was perfectly OK and I don't think you can get a toggle switch in without major surgery anyway. I'm not fan of slide switches either, they are always the first thing I have to replace in Gisela's garden lights and fountain pumps etc, usually due to corrosion. But considering the low usage, without getting wet (unless you fall in the pond with it๐Ÿ˜ฎ), it will have in your TX it shouldn't be a problem. The reason your rechargeables kept popping out is that many of them are a fraction larger than the alkalines. I've had this problem with several devices. I use alkaline in my DX6 and my Turnigy clone. No problems. The only TX I use NiMH in is an old Graupner MC-10, 40Megs for my submarines. But it was designed for use with a 9.6V pack in the first place and has a charging socket. Does your DX5E have a charging socket? No! Neither does my DX6. Cheers, Doug ๐Ÿ˜Ž
