There are a few items that can now be attached to the superstructure: vents, life buoys, doors, grab rails, and hatches. These won’t be easily knocked off so they can go on now. The real boat has a mix of old orange, and bright red new lifebouys, mine are all red.
The insides of the vent covers have been white, and red, over the years, and the seals have been black, and red. I’ve gone for white covers, red seals.
The grab rails were pretty simple. The single length bow section curves around the bow in a big 'U' shape. The rail sits out from the side by 2mm. I soldered it in place and then removed it for clean up and painting. That required a bit of delicate repositioning. Using spacers and having most of the supports only go into the superstructure about 1.5mm really helped. The ends and the supports on the bow corners, and a couple in the middle of each long sections are much longer and allowed the thing to fit around the superstructure snugly.

Likeomg, that is the boat that I have bought from China.
Blazinbeaver, I will make contact with them. |

Well its been quite a few months, and progress has been slow due to other committments. Mainly turning my garage into a decent workshop - still a work in progress! An updated version of the webpage is here:
https://new.express.adobe.com/id/urn:aaid:sc:EU:c9b4d793-408e-4fa3-a6b4-90b703e0bf56?invite=true&accept=true&promoid=Z2G1FQKR&mv=other I made a cardinal mistake with my approach to the mahogany layer on the hull. I tried to 'veneer' it with some relatively narrow strips of veneer: this worked fine over the rear 2/3 of the hull, but the bow section with a 3 dimensional curve proved to be a nightmare, requiring long thin wedges to be inserted, and getting a good contact with the underplanking also proved challenging. I should have stuck to narrow strips of planking - it would have been quicker and more satisfactory but you live and learn. Reading DJWs post on his foredeck has also sent shivers up my spine! All the bestTom |

Got home from work today around noon, meaning I have 2,5 days to get that gearbox installed before the weekend, when there is some RC boating to do.
The gearbox came with a very marginal filling of grease of which I had zero faith that it would ever migrate through the box to lubricate the spinny bits. Especially the bearings of the epicyclic wheels worry me a bit. Better greases are availlable, but the downside of grease is that in order to replace it, the gearbox needs dismantling and solvent-cleaning. So I decided to "waterproof" it, and use an oil filling. If I would drill a drainport, I can replace the oil without dismantling. There is not much volume availlable, and since I simply LIKE doing stuff differently, I did the following: I drilled a tiny hole all the way through into the bottom of the outer gear ring, and fitted a bent tube into that hole. This hole is located in the path of the epicyclic gear wheels, and I expect each passing of a gear, to push a tiny bit of oil into that hole, creating kind of a pumping action. A 2nd hole is drilled 90 degrees offset to the first one, but also offset to exit in the plane of the rotating gear carrier.. With a bit of luck, this creates a circulation, where the epicyclic wheels push with each passing a tiny bit of oil in an external line directing oil towards the gear carrier. The pic unfortunately is rotated clockwise 90 deg, the left side of the pic in reality is "bottom" EDIT: and dang.... Not only did I manage to seal up that gearbox, the oil circulation actually works... A lot slower than I hoped, but never mind that... it circulates, and that's what's important! I have Epona Z, a heavy duty gear oil, in three viscosity classes, 100, 150 and 220. If 220 turns out running hot, I guess I'll try the lower viscosities. |

Afternoon All
Well, the mahogany deck V1 is no more... ![]() Had to use a couple of chisels, not a nice task... But that thin mahogany just had to go. I think it's also giving me the opportunity to blend the forward deck to the side decks a little better. There's a small step in levels between the birch ply of the side decks and the lime / bass planks of the forward deck: ![]() Next task is to cut new side panels and forward deck panels. Also been playing with the Arduinos again. ![]() The dashboard is now getting 2g servos behind all the dials not just the tachos as I originally planned. As the build is 1/5th the dash is about 35cm wide, the dials are 25mm and 20mm faces. The tachos will be driven by one Arduino that takes a PWM feed from port and stbd ESC channels, these servos / tachos will then show the power being applied through the motors. I'm using an Arduino rather than a y lead for a few reasons. 1. I want the tachos to operate correctly in forward and astern, to show the motors are operating independently when used for manoeuvring on shafts. 2. I want the tacho dial pointers to do a full sweep on power up, then settle to an idle position and sync this to the sound system. 3. I want the tacho pointers to display say 600rpm at idle, so when the sound system is active on tick over, but no throttle applied. 4. I realised that I then need the system to be smart enough to understand when the sound system is powering down, and so to set the pointers to zero rather than just power off. A second dashboard Arduino will control all the other dials except the speedometer. I'm thinking that these just need to do a full sweep as they wake up, then rest at a set position (i.e. fuel level and so on), then on power down of the sound system, return to zero like the tachos. A third Arduino... Will I think be needed for the Speedo as this will be driven by a GPS module, for providing speed across the water (SoG, Speed over Ground). I'm using a GY-NEO6MV2 NEO-6M GPS Module (£7.59 from Amazon), SoG is then passed to the Arduino which deflects the Speedo dial pointer accordingly. ![]() So far I have a testbed with couple of servos doing the startup and shutdown routines described above, that code will be needed on the three Arduinos and can be extended to more servos quite easily. I also have the tacho code servos going to an idle position after startup, and then responding correctly to throttle input going ahead, but not yet astern. Still a work in progress, but it's coming along. ![]() And finally that GPS module, not started with that yet: ![]() That's about it for now. Off to do some sanding and cut some mahogany... Best regards to all. David. |

Hi Pete,
Have you received anything further from Shuttleworth about the arrangements for the model boat element of their fete weekend at Old Warden on 12 & 13 July ? I assume the plot will be the same as for the two model events held there last year. Gazebos erected near the lake behind the hangars and car parking in the field between the hangars and the lake.
