David...did I read that the intention was to colour the exhaust tube internals Red? .....I would have imagined Blackened [and by chemical blackening]


Engines of this vintage irrespective of state of tune would have exhibited a Black deposit at the exhaust tailpipe........


Remember all those days before unleaded fuels in motor vehicles?

Morning Derek


Yes, it seems to be one of those Riva signatures that sets them apart:








Interesting link Andy, I guess if someone can afford a full sized Aquarama that someone can afford keep another someone on to keep it shining... including the exhausts...


Best regards
David.

Sorry David, I have never inspected images of these exquisite Crafts exhaust systems   :o


Thinking more, could the actual Craft engines exhaust headers and exit pipe, be a Nickle plated, 300 Series stainless material, with the exit pipe internals be electrolytically copper flashed to provide the coloured surface as seen? :-X


[courtesy of the Electrochemical Series, and to improve adherence to the sub-strate & finish of the final product, steels are flash plated with copper prior to either Chromium or Nickle plating - with Chromium for improved surface hardness or abrasion resistance, and Nickle for the greater reflective quality]


I am sure there must be a chemical treatment to alter the surface colour of brass to this ~~ chosen reddish, without adding any real depth [as red paint would  >:-o ]

Or just paint some red on these little pipes! Interesting link about the red paint!  %%

Hi Derek


I've got a few pieces being prepared for chroming but not sure about getting a red finish, I will look into that as it sounds interesting. As this is purely aesthetic I've used red paint.


A little more progress today. Water inlet pipes added to exhausts.





And soft soldered in place.








Some Tubing added, and a base coat of red...





Another coat tomorrow then some gloss acrylic to seal. Then add the flanges.


Regards to all.
David.

Evening All


Good progress today.


This is what I'm using to paint the hull, I'm sticking with the Plastikote range in an effort to ensure no conflict.





The Trade Plastikote was a lead from UKMike, the 3M vinyl tape a recommendation from MarkT. Thanks to both.  :-))














Then add red...





And remove the 3M tape...











A couple of minor areas where red has seeped under the tape, but probably my fault rather than the tape. Shouldn't to too tricky to fix.


It's starting to look like a Riva...  :-))


Plan now, I'm going to let the red cure for a couple of days then use some cutting compound just to smooth the finish and edges then gloss sealing spray over the white and red.


Great weekend to all.
David.

Afternoon All


Slow week, been busy in the garden...


Have cut back the hull paint and masked up the boat again.








And applied the first clearcoat gloss. Will see how it dries, but I'm thinking three coats required.





Have clearcoated the inside of the exhausts too. After the clearcoat I can seal the exhausts in place.


Regards to all.
David.

Clearcoats done. Props on and grubscrews threadlocked. Rudders in and greased. Exhaust flanges being shaped and drilled to take 1.2mm stainless screws. I think the flanges will just be aesthetic, applied once exhausts are bonded on place. But they'll look the part...









Best regards to all.
David.

Looks the part! Was the red line painted with a brush or sprayed out of interest?

Morning Stuw
The red line was brushed on. That may have been an error on my part with hindsight. I did get the red in a spray can too, but my experience with spraying the white was the it was really thin, and prone to creeping under the tape.
The painted line didn't creep, but isn't as smooth as I'd like, it left brushmarks, hence I had to re mask and cut it back. Then I clearcoated to bring back the red gloss, and blend it in better.
If I were to do it again, best results would come from an airbrush I think. Which I don't have...
Best regards
David.

I think that its turned out really nicely Dave you've made a nice job of it.


If you get paint creep the easiest way to solve this is to do the following.


Mask up your line and the entire boat to stop any over spray and then spray a fine layer of white.  Let this dry for about 15 minutes and this thin layer seals the edges of the masking tape.  Now spray the red and get the masking tape off as soon as you possibly can.  I never leave it more than 5 minutes after the final coat

That's useful to know Mark.

She's looking lovely David, won't be long before she's on the water.

Mr T... That's a great solution, makes perfect sense. I'm learning so much with this build, and that's a gem, thanks for sharing your experience.
I have a second Aquarama in mind when this one's ready. I've learnt so much I really want to plough that experience into another build.
Meanwhile, exhausts are installed, so now the hull is watertight, I can see a lake test coming up...

Thanks guys.
David.

Your welcome mate you can also use a clear coat to seal the edges too just never let it dry.  The grain in the wood above the paint looks awesome - I really like mahogany its just a lovely wood to work with  :-)   Looking forward to more updates

Agreed that the mahogany looks beautiful, here's another pic. And you have to build one..!

Looks great! Great tip about spraying white first too. Iím learning from all your efforts - thanks.


Quick question to anyone if I may?
If youíre applying more than one coat of white for example. Do you spray one coat and remove tape, allow to harden over a few days, then remask and repeat ó


or do you apply the coats after each other before first one dry?


Probably a ridiculously stupid question. The thought of trying to remask perfectly multiple times was putting me off! But it may be the correct way.

Not a stupid question, but yes, the prospect of re-masking for every coat is frightening.  Apply multiple cpats one after the other, leaving 10 or 15 minutes between coats.  As long as you don't spray too heavily, you will build up a nice even coat in an hour or so.  And as has been said, carefully peel away the tape before the paint hardens to prevent any flaking off.  Job done.

Think that would be my understanding too. (Now...) Overcoat when touch dry but not cured, build up a few coats, then off with the tape. Ease it back over itself, and off.

Just realised there are still two holes up near the bow that need to be sorted before a lake test is a good idea. Could just tape over, but really the job needs doing...


So the dock lights need to be fully fitted.





I have a couple of the Cap Marquettes dock lights kindly sent over by UKMike. I'm going to modify them a shade, but use them as a basis.


The inside of the dock lights need to be white, so will be painted as they're currently chrome. Then I'm going to thin the original flanges, cut some acetate sheet to seal the units, and then finish with the Amati supplied flanges. And finish with 1.2mm Stainless screws. Same as exhausts.


Made a start today by creating a basic rig to hold the units so I can work on them. Here's the start point.





So above are the original flanges that need thinning, and below are the Amati flanges that will be polished up and will take the screws.





Will update when they're further along.
David.

Morning All


Busy week but had some time yesterday to progress the dock lights.
So, all drilled and complete on the build rig.





Screws are 1.2mm stainless. Acetate sheet is fitted but hard to see... And here the units are fitted to the hull.





Very pleased with the result. They're sealed and look pretty realistic I think, a hybrid of kit and Cap Marquettes hardware. Voltage is adjustable, looks like it needs upping a shade.








So now the hull is sealed and ready for a test run I think...





Best regards to all. David.

Thanks Both. This is the full sized dock lights to compare.





Looking forward to getting the boat on the water for a test. This week I hope. Will be videoing the run...

Just spent a couple of hours on the Riva. Got the windscreen conformed to the correct curve and the deck drilled to take it. Also the various upholstery panels finished and in place.
