    πŸ“ Fire Monitors Part 1

    View All
    The white metal items supplied are OK but really donβ€˜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 I’ve seen. The bar has been set so here goes, whenever an item like this is been contemplated it’s always good to spend some time in planning a sequence of operations and assessing the problem area’s at the start of the work and if possible dealing with these parts first. Failure of the difficult process doesn’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 wasn’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. That’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 β€œU” 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 it’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 β€œmain pillar fitting” and the monitors final β€œexit pipe” 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 β€œpivot post top” that feeds water through the 2 brass pipes into the β€œjunction block” which then feeds into the exit pipe, sounds all very simple?
    Having made all the components, it’s time to think about fastening them all together. First items to be joined are the β€œupstand pipe” to the β€œpivot post top” X 2 also the β€œfeed to exit pipe” and the β€œjunction block” 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 β€œglassy”, 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

    Have you thought of using a sail servo. I'm just about to trial my system, (I just finished painting my efforts which will be in my blog shortly.) Looking at this type of servo it seems this one just rotates 360 degrees.
    Or have I got this wrong? I'm just about to purchase one, so thoughts please before I do.

    Really nice work Graham, does the copper water inlet pipe below the cabin roof rotate?
    If as I think it does, then having 270 deg really isn’t required or appropriate as the pipe will get twisted and hopefully you will be only spraying water over the side (not back and front as guns do) and only having squrting power on one side of the boat will not really be noticeable.

    as others have said measure twice - cut once, try fit twice - glue and pin once, taking your time is no bad thing, rushing this type of work only results in a poor end product and rework of rushed work. Im still working on mine over a year after starting

    Its looking like a good planed build keep it up.

    Go to your local DIY and get the two part wood filler from Cuprinol. It sands really well and is quick, you can mix a small amount and within 10 -15 mins its ready to sand.

    Sorry, I did understand the question but I’m not a mind reader and your harbour shows an African Queen which does apparently have something that looks like a boiler - hence the question. I’ll leave it to your next door neighbour then.
    PS post and phone?

    PS whats the problem with the existing boiler? I assume its the African Queen in your harbour your doing

    πŸ“ York model boat club regatta
    23 days ago by mturpin013 ( Lieutenant)
    Flag
    View All
    Here we are, a year later and we went again to the York model boat regatta at Laytham Camping and Caravan Park. It was time to give my first boat its maiden voyage. You may have seen the boat in my harbour, the Freeman 22 Norfolk broads’ cruiser which now belongs to my grandson. I managed to finish it for his 6th birthday hence the name (Tyler JWT 6). It sailed very well and achieved a realistic speed, turned well and reversed-turned very quickly.

    I am going to make some adjustments to its weight distribution because although built to specification I felt it sailed too low in the water and slightly bow heavy. So the solution is to remove one of the 6 cell NiMh batteries which is only there to balance the weight, the powering single battery will now be located in a central position slightly towards the stern.
    I’m now looking to join this club which has been really welcoming in a fantastic location.
    PS hopefully video to follow

    Graham, the boat is looking great, as others have said a new coat always improves things. I can also confirm the issue with spray tins (Acrylic) as the boat Ive just finiashed for my grandson had the same issue. Im am spraying my crash tender with commercial cellulose using compressor and spray gun and although the drying time is also an issue in terms of time after a couple of weeks it hard enough to treat with flatting compond to achieve that polished finish
