Let’s get some paint on! - Posted: 21st Mar 2018
Last couple of days things have moved on nicely! I have done some more work on the forward cockpit adding window frames from plasticard, still a long way to go on that part of the build. Cockpit is still loose from the hull, will be glued on once all the extra detailing has been completed.

Have started to paint the exterior hull and add some decals. After several coats of grey and red primers with flating inbetween, have left the bottom of the hull oxide red. The blue is "Ford Royal Blue" which is a recommended match for RNLI boats. Some waveneys appear in a light blue, but I am basing mine on 44-003 which was the darker blue. Red and white trimlines added, bumper strips painted black, lettering was from eBay (search custom vinyl lettering). Finally a light coat of laquer to protect. several coats of laquer will be added at the end.

Well Doug, if you don't push you won't know the limit. Limits are not a set rule in life or in engineering.
Cheers Colin.

Nice paint job on the hull.I have to wait for warmer weather to paint.
Bridge/Cockpit/Flight Deck construction - Posted: 19th Mar 2018
so, having been at work all weekend, today saw a day off and a few hours to start building the foreward cockpit bridge thingy. There will be quite a bit of shape changing mods to this part as we build, simply because the Dumas kit is of the 44ft Coastguard cutter and the Waveney class Lifeboat has quite a few differences.

Changes to make include the windows, the rear walls to be extended to take acount of extra windows at back of cab, forward sloping front piece, engine intakes on both sides, and changes to the roof.

Still waiting on a reference book on "Waveneys" from ebay, should have been here by now! that will give me the change to start super detailing the exterior decs, cabins ect.

Rear Cabin construction - Posted: 15th Mar 2018
today has seen the rear deck and cabin constructed. I lined the deck piece with some mahogany strip for a neater finish on the edge of the crapy liteply. Construction of the cabin was straight forward, this was followed by shaping, sanding, filling any gaps and a couple of coats of sanding sealer ready for paint. I have also added the railings and stanchions to the roof of the cabin as a start to the detailing to come.

I have ordered a book from Amazon which is a reference book of the Waveney Class lifeboats, so hopefully there will be ample photos for the detailing I hope to add as we go on!

Now there's an idea, thanks Sky👍
The rest of my fittings for the Sea Scout are chrome so I didn't want to use polished or painted brass for the 'pulpit' railing.
Alu should polish up nicely.😊
Response by marky on the 15th Mar 2018
Doug i know you wont need vast amounts of aluminium rod for your hand rails but a kg of 1.6 aluminium tig welding rods retails for about £15 enough to do about 100M of hand rail ,a lot cheaper than a hobby shop ,if there's a fabricator near you he/she may be able to throw some ends your way. Cheers Marky
Response by RNinMunich on the 15th Mar 2018
Good tip Marky,👍 I'll look into it. Otherwise I was thinking of stainless steel, which is a pain in the 'sit-me-down' to weld 😲
more progress. - Posted: 14th Mar 2018
First job today was to reduce the rudders by 1cmx1cm which I think not only looks better but should reduce the affects that have been mentioned in comments below.

Ive fitted the cockpit which I assembled yesterday. Its not the best fit into the deck, however, I shall blend it all in with some balsa strip, sand, filler, sanding sealer hopefully for a seamless finish.

I have pictured the 2 x Hobbyking waterproof boat 30 amp esc. These are supposed to be water cooled, however I am not going to fit the tubing and start drilling water pickup and exit holes in the hull x 4 until I think that water cooling is going to be necessary. Once I have watt meter readings for 2S and 3S lipo, it will give me an idea what the ESC are going to be like. Of course if you guys think I need to go water cooling, please let me know! I have an Mtroniks W-tail mixer that will allow the motors to be synched to the rudders allowing the inboard motor to slow or stop when turning. Never used one before, so may need to some programming once hooked up, we shall see.

Last job today was to shoot a could of coats of red oxide primer on the lower hull to see what the resin finish was like. on the whole not a bad finish at all, just a could of tiny areas that need a little sanding for a faily blemish free finish.

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.
