Thanks David

Seems like a good approach for when I finally get to the seating etc. in my various Fairey builds. Look forward to seeing how you deal with the seats.

I thought that some sort of heating had been employed - I never would have thought of producing the desired effect like that - shows how good it is to learn from others.

Indeed. Iíd imagined a soldering iron dangled nearby but this method gives you a great result! Nice work

Morning Both

I was thinking that there are some sections that will probably need a heat gun to help the material soften to allow it to conform to a smooth curve without wrinkling. The deck of the Aquarama across its beam has a lovely shape. I'm thinking glue the foam to the faux leather, soften the faux leather in the curved areas, conform it to wrap around the foam backing, then clamp it.

But maybe you're right. Generally adding some heat would shorten the clamping time when applying the indents, I'll try that and report back.  :-))

Best regards
David.

Had a couple of hours on the boat upholstery today.


Trimmed the 2mm plastazote sheet to the shapes of the cockpit and sundeck coaming.  Contact adhesive to attach the foam to the faux leather material. Then trimmed the faux leather to allow it to be folded over the edge of the fom, and glued. Just had to slice the overlap in a couple of places around the curved areas to persuade it to take the correct shape.





I've added a few more 'teeth' to the indent tool so I can clamp about 20 indents at a time. I'm heating a little to soften the faux leather (thanks Chris...) Then clamping for a few hours or overnight. Seems to be doing the job.


This is a fit check for the cockpit coaming before the indents are applied:





Best regards
David.

Glad to help, even if it was a guess! Where do you get your Plastazote and faux leather from?

Hi Chris


This is the 2mm foam:

And the Faux Leather. I think its same as UKMike uses. It's the thinnest I've seen, you can order a small sample. Then if its right I ordered a 1mx1.4m piece.  I used light cream, and some of the red too as a highlight and piping.

Thanks David, that's great.


I might get my wife interested once I get to the upholstery!

Afternoon All


Dry fit at the moment, but I think the sundeck surround is coming along:





Also working on the aluminium case that holds the ESCs. I've decided to add two 20mm fans to draw air though the case. It got a bit warm on the test run.  Its not ideal, I wanted to use water cooling but couldn't think how to do it with the volume constraints in the case.  The case will still act as a heatsink and also a duct for the airflow.  I'm thinking maybe a temperature sensor to power up the fans, either standalone or using the ESCs own telemetry...


Putting the indents on the cockpit coaming now and will post again when its all ready.


Regards to all.
David.

OK, still dry fit for the time being, but now the coaming for the cockpit and sun deck are done.











Onto the seating, a sterner test I think...


Best regards to all.

Evening All
A few hours of progress over the weekend.
I've added in three more sensor points for detection of water in the Bilge. These are now by each of the rudders and prop shaft seals. They come back to the port electronics case then via an Arduino to register as telemetry on the transmitter.








Also finished the ESC case mods. The pair of fans, and I've ditched the solid mount. It makes for a better airflow and cable route. But also allows the ESC case to be isolated from the hull using some of the foam. If the ESCs are contributing to the high frequency sounds, this might help.


To keep power consumption down I've decided to  control when the fans are active using a logical switch in OpenTX that monitors the ESC temperatures, so when they hit a set temperature, the fans power up.











I have added some of the faux leather to the sundeck surround to get a better finish.











I've started to create a new tool to apply the cushioning indents to the cockpit seats. Will then start to experiment...


Regards to all
David.

I've made up the wider tool for applying the seat indents and used it on a test piece.  This test piece is 5mm balsa and 5mm Plastazote foam.





Then clamped overnight to get the indents into the foam.


Resulting in this, which is a start...





Then added some UHU Power glue.





Added the faux leather and clamped for about 2 hours...





And this is the result.





And I'm happy with that.  I'm hoping that the glue with go some way to stabilising the indents, I'll leave it a few days and we'll see.


On another matter, I thought the Aquarama deserved a proper stand as its got this far.  So I've made one up that resembles a hauling out sled (well I think it does...).








Its going to get a coat of grey, and the areas that touch the hull will get some padding.


Best regards to all.
David.

Afternoon All


Thanks for the comments chaps, trying hard to do the Riva justice..!


Stand is now complete in grey, and padded to protect the hull.  (ESC case in the background)











And now the fans have been installed for the ESC cooling, I've added the electronics and reinstalled all the RC hardware, I can feel another test coming on when weather allows.





Added some polystyrene under the batteries, and filled the volume forward of the motors too, hoping that will stop some of the whine...  Also added sound absorbing foam around the motors.


There's a lot shoehorned into this hull, and that's one of the reasons for considering a larger build.


Very best regards to all
David.

Looks superb on the dull steel toned stand David  :-)) .......


Just a question, not sure how dusty your home is?, but best make sure it's your job to dust the vessel.... O0


[background to this is ....many years ago, my better 1/2 & new to the latest computers saw it as her task to clean the matt black Hewlett Packard vertical desktop with Mr Sheen {aerosol fluro teflon furniture spray polish}.....well all this was OK until the mouse refused to work :o


Yes, in those days with a Track Balled mouse + Mr Sheen on the Mouse Mat made such a slippery surface, the ball just refused to rotate]  >>:-(


Looking forward to seeing your Riva on the water again
