Got a bit more done on the cable guide assy.


Trammel assy built up.




It still moves along the rails........ :}




And soldered onto the main frame.



Still a lot more to do until it is finished. I dread putting the next part on in case something unsolders itself and falls off........ %%

So Stewart says ..."dread putting the next part on in case something unsolders itself" .....heatsinks......an old cotton handkerchief.....soak with water and fold around the closest pre soldered joints that you need to protect from additional heat

Engineers clamps fastened close by the joint to be soldered are also a good heat sink [the Bakers flux will soon destroy the blued finish >>:-( ....but are very useful for the task at hand]

Slow progress due to some festivities.








What is the best way to clean this up ready for painting?


Cheers

A little bit more progress, but slow as icicles forming on my nose in the workshop.
Moved onto the front mast, marked and drilled hole for mast socket, soldered 3mm and 4mm tube to make the mast. Small length of 5mm tube for the socket, flange and side ribs soldered in place. Drilling a hole from access area under the wheelhouse to the base to run lighting cables. Anywho, was really strugging to check if the mast was vertical as the forcastle has a 2 slope. So levelled up the boat so dead flat both ways, then dropped a plumb bob fron ceiling, got it positioned dead centre of the mast hole, then raised it up until it was the height of the mast to. No it a simple matter of setting the socket with epoxy and should have a perfectly vertical mast.

Hi Stewart what a simple idea - I think I'll steal that one from you for future use  :-))   Nice to see the build coming on.

"What is the best way to clean this up ready for painting?"

Stewart.......a very light grit/powder/plastic bead blast is probably the best in providing a good keying surface for the primer........ Derek

Hi folks, bit of an update on the build.
 Tx is FlySky FS-I6S with the 10 channel rx, all hooked up as instructions but could i get it to work correctly......no, it would do weird things? d costs an arm and a leg if it goes wrong!


Just a thought ....... Are you are using DRY (1.5V) batteries and NOT rechargeable (1.2V) batteries? Tx is only 4 cell battery box and no recharge plug

I've always used green scotch bright pads to get the worst off and then dropped down to the finer grey coloured ones.  They tend to fit around everything and make the job nice and easy.  I then degrease with either IPA or panel wipe for bare brass - either one works just as well as the other.  Oh and buy a decent branded etch primer as I have found that the cheaper ones are rubbish.

Can someone explain what colour these lights should be, what are the light sequences and why are one smaller than the other?
Many thanks in advance.

I am really struggling to understand these bloomin' lights.......I have read the nav light rules and regs but making worse for me......DOH.
I cannot see anything with 2 masts? I am guessing the forecastl mast has red on top anc the lower 3 are white (360)? Why 2 sets of each? (Spares)? Main mast, not got a scooby doo. At the back of the wheelhouse another 2 sets of 2? Yellow and white? A complete mystery. I am wanting to order the lamps and bulbs or coloured lamps if I knew which colours to get.
Appreciate your help guys.

Yes! There is one spare to every light in case of a blown bulb. White and yellow stern lights are for towing. Top lights with 360degr visabillity are anchor lights. The ones on the side mast are red-white-red used for restricted maneuvrabillity.
Someone else will surely add some more facts for you.
All the best!

Thanks Hama, good info....... :-))


Would it be OTT to have the lights in pairs like the real boat? Maybe one working, the other a dummy?


Cheers guys.

Got a bit more done on the mast. 1st pic shows the outrigger posts glued into the bulwarks with a 2mm pin sticking out to accept the outrigger legs and a piece of wire coming out of the base to pull cables through for mast lights. 2nd shows the basic mast in place. Still a lot to do but it's moving in the right direction.

Well, while waiting for my lamps from shapeways I decided to have a tidy up. My electronics bench had become a bit of a dumping ground. All sorted now with a new back panel along with new storage bins and boxes. Most components have a new home with a laminate to locate them, a nightmare sorting several years of neglect. Now to unearth Granit and Little Lizzie from under all the junk.........oh happy days. Looking forward to sorting the other end of the workshop as I would like to have seperate benches for metal/general work and woodworking.
Soon as lamps arrive I can get on with the front mast.

Hama was mostly correct with the lamps and sequences. The yellow over white at the stern for towing. 3 all round whites at the mast for towing as well as white over red over white, which is for restricted manouvering, although from what I can see from internet searches, the 3 whites seem to be neglected and replaced entirely by the white over red over white configuration. Try and make sense of it all........

Hi Stewart,


Just catching up with your great build.


Regards nav lights, there is great iPhone app from Imray ( the chart people) named "Marine Rules & Signals" that has graphics that show all the various configurations within "Lights & Shapes section that should provide the answers. Search "Imray" in the app store to locate it. Can't remember if it's free or not, either way I have it & I would not of payed a lot.


Cheers
