Devil in the detail! - Posted: 13th Mar 2018
Today has seen the prop shafts and motors installed, all nice and straight and bind free. Once all
That was epoxied in and set, I made a pair of prop shaft struts from plasticard and tubing, not that it provides a huge amount of support but adds to the scale appearance. I also fashioned some approx scale sized rudders using standard off the shelf rudders, removing the blades and making new blades with 0.8mm brass sheet, pinned and soldered and painted in oxide red primer.

Last job of the day was to start building the cockpit floor and to give the hull another coat of resin.

Hi Skydive, agree, for your purposes on a scale displacement hull the struts aren't that structurally important. You shouldn't get significant whip if she's scale-powered.
Re your A/C experience - might be calling on you soon wrt my Catalina and a Carson convertible Boat / Stub Wing / Delta Wing creation! 😉
Fancy a short break in Munich for Flying instruction???😁
Happy building, and sailing when spring finally comes, our spring was from Saturday until today, from Friday the forecast is freezing temps (-8°C😡) and more snow! Ciao Doug 😎
Response by RNinMunich on the 13th Mar 2018
PS: to assist the steering you could use this dual ESC and rudder mixer combi, BUT only with brushed motors! More than adequate for a Lifeboat! Just an idea, ciao Doug 😎
Response by RNinMunich on the 13th Mar 2018
Thanks for the 'Like' Boatshed👍
In no way wanted to denigrate your advice, just put it in perspective for this kind of model. 😉 Cheers Doug 😎

Clothing complete, fenders on! - Posted: 12th Mar 2018
So, managed to get all the glass clothing done at work at the weekend! So far, 1 coat of resin followed by 2 thinned coats to come.

Today has seen all the fenders/rubbing strakes added. It took some careful measuring to get positioned correctly but well pleased with the outcome. It paid to pre-shape them prior to fitting. I’ve added filler where needed and a couple of coats of sealer, all seems to be faired in nicely. May need some touch up after priming.

Also fitted the rudder mounts as today’s final job. Tomorrow should see the prop shafts fitted, motors mounted and will make the shaft struts. Postie arrived with some RNLI resin crew figures that will add a great touch when painted.

Don’t tell the wife! - Posted: 7th Mar 2018
Mrs “H” is out tonight at a show, so thought I’d get the next piece of cloth on in the kitchen whilst cooking up a fray bentos pie all to myself!

Nice work!
You're slowly catching up with me. I've been busy sanding coat number 7 of resin.
I also deviated from the plans and opened up access to undet the fore deck
Response by Skydive130 on the 9th Mar 2018
Why so many coats of resin, I’m hoping 3 will be enough like when I cover model aircraft?

Glass clothing commenced - Posted: 6th Mar 2018
Spent most of the morning sanding, flating, sanding sealer, small amounts of filler where needle before a final coat of sealer and last sand. Left with a super smooth external hull!

I’m hoping to cloth the hull in no more than 3 pieces starting with the transom as seen in the picture. Might be a bit slow next few days as back in day shift from tomorrow, might be able to sneak it into work Saturday?

"might be able to sneak it into work Saturday?"

Don't end up in the 'Glass House'!! 😁😎
Response by Skydive130 on the 6th Mar 2018
Should get away with it as I’m actually in charge of the glasshouse or guardroom as it is these days ha ha
Response by RNinMunich on the 6th Mar 2018
That's cheating 😉 but GO FOR IT!
Hull is looking great 👍

Let’s make a stand! - Posted: 5th Mar 2018
More progress today! First thing was to make a stand from 6mm ply and 18mm dowel using the hull templates as described in the instruction sheet. Was a good excuse to get my scroll saw going! The rear stand will have some more cut-outs to clear the prop shafts, will do that when I’ve installed them.

This was followed by a very messy and dusty couple of hours sanding and flaring the hull external sheeting followed by a good dose of cheap wood filler ( £1.99 from a pound shop in stowmarket, works well, sands nice!) in any gaps, cracks and imperfections. Will leave to dry overnight before sanding back and refilling where required before a couple of coats of sanding sealer, sanding back then on with glass clothing.

Decks in, ready to sand, fill and cloth! - Posted: 4th Mar 2018
Been a slow few days with work and chores around the house, but managed to get in the workshop today. Fore, centre and aft decks in, nose block rough shaped and glued, gunwales fitted. I’ve faced the rear and fore deck thingys with1:32 ply for a neater finish and replaced the kit gunwale thingys with a sandwich of 1:32 ply and 1:32 balsa.

Tomorrow I have a “me” day as wife at work and I’m off work, so it will be a good chance to sand hull, filler were needed, sanding sealer, more sanding ready to start glass clothing Tuesday all being well.

Planking done and other stuff’ - Posted: 27th Feb 2018
So, after a weekend away with “she who must be obeyed” have managed to do some more over the last couple of days before nights tonight. Planking is now completed, just needs external shaping, sanding and filler before glass clothing.

Have cut holes and added all the fixing points for the prop shafts and made the motor mount. All square and inline. Prop shafts won’t be fitted properly until I’ve clothed the outside. Stuffing boxes will be epoxy and isopon P38 fixed inside the little boxes I’ve made where they exit the hull for added strength.

Last job today was to give the inside of the hull a good dose of resin to seal it all up.

Hi Gerry, I’m possibly not the right person to ask, especially if you’re considering 3 motors? My best advice is to make your own post asking other more experienced boat builders to advise. I’m fairly new to boats moving over from aircraft.
Response by Gerry1 on the 27th Feb 2018
OK thanks so much

Exactamente Skydive! 👍😉

Planking almost very nearly finished! - Posted: 23rd Feb 2018
Finished nights this morning, had a couple of hours kip then thrashed some more planking! Stern end finished, main hull finished, just the bow uppers to put in. Once completed, will get some pva squeegee’d into the inside joints between planks and formers then will give the inside a couple of coats of resin. Once that’s done, rough sand the hull and fill the remaining gaps and blemishes with wood filler before final sanding and touch filling prior to glass clothing.

Before I glass cloth, shall install prop shafts, motor mounts, motors, install decks then onwards with clothing.

Looking good
I set the rudder shaft the same as you,...

Planking near finished - Posted: 21st Feb 2018
Have added a few more planks over the last couple of days before and after bed as on nights. Gaps should be closed by Friday? Have also marked exit points for prop shafts and marked and drilled rudder mounting holes.

Aha! Moonlighting methinks 😉

Planking progress - Posted: 19th Feb 2018
Over the past couple of days, planking is moving on. Working on 2 planks per side per day allowing overnight setting time before moving on to next row. Starting nights tonight, so will try an add a couple of planks each day before bed!

Response by RNinMunich on the 20th Feb 2018
So far so good 👍 I admire your patience.
Thinks! If you are on nights again you can carry on planking (sounds vaguely familiar! Sid James & Kenneth Williams & co? 😁) while twiddling your thumbs waiting for the Russkies to attack😉 Cheers Doug 😎
Response by Skydive130 on the 20th Feb 2018
I could plank on nights, have done before ha ha! However, managed to get another 2 rows on before and 2 after my day kip, the gaps are closing! Photo update tomorrow.
