It did develop a bit further, all was going well...





Until it stopped going well, and went rather bad.


One side went OK when adding the outer rim, nice solid joint and in the right place, always a bonus, had a clamp attached to the main spoke to stop the other joints melting...  But then had not enough heat from my small proxxon torch, so switched to the larger torch. Big mistake.





The outer brass rim just melted.  {:-{


So I swore and went and did something else that didn't involve a blue flame...


Will try again tomorrow once I've cleaned off the botched attempt.


David.

Try covering with firebrick the area not to be heated? The trials of perfection!

David - seriously your progress is quite simply amazing mate  :-))


With the steering wheel though I would use soft solder.  I can't see how hard solder adds to the lovely wheel that you are making.  Its less heat and will make life so much easier without compromise on this particular part.


What ever you choose - its an amazing build and good luck!

Morning Paul and Mark


Yes to the better use of the firebrick, they're quite easy to cut so I may try to be more accurate where the heat is kept. One of the issues seems to be that the rim is absorbing heat faster than the spoke, as its a larger mass and attached to a heatsink. Maybe I just have to remove the heatsink and work faster...


I'm resisting soft solder as I want to chrome the wheel. I don't think soft solder will take chroming, at this point I'd be very happy to be told that it would...


Anyway. Waiting for some more 2mm bar to arrive so will be cleaning up the wheel if I can today and contemplating a new approach that doesn't involve the large blowtorch.


And whatever happens, the results will be posted.


Best regards to all, thanks for the support..!
David.

Might be worth having a word with Cupalloys www.cupalloys.co.uk who do a low-melting point with added silver. I think it's about 280 degrees, rather than the 600. I've used it when I've had to do some differential soldering.

OK...  An update.


@Tony, thanks for your words of wisdom.  And I should have listened to you when you suggested this approach first time around...   :-))


I think there are a few phrases to sum up current situation, based on '...Old dogs and new tricks...'


So I had understood for a long time that chroming soft solder was not a good idea. Too soft to be a robust surface for the chrome plate, and a danger that the plating process (the plating bath) would melt low temperature (soft) solder.  And I just accepted that as a fact.


On TonyH's recommendation I've looked at the Cupalloys link, and have spoken to them.  They indeed have a soft solder that has a silver content that takes the melting point to almost 320°C and is a bit more robust. They said that it can be chromed as long as the plating bath is below that temperature.  So I spoke to Ashford Chroming who confirmed that plating bath is way below that temperature and that they can (and do) chrome plate soft solder.  So it really comes down to whether the soft solder is strong enough for some of the parts being joined.


I've placed an order from cupalloys for some more silver solder and then some of their 'CuPSol' high melting point soft solder so I can try it.


https://www.cupalloys.co.uk/store/1m-CuPSol-Wire-1-0mm-dia-Flux-Cored-p276411620


So, I've learnt something today.  And it should make life a little easier making up these brass parts[size=78%]. [/size] :-))


I'll update again when I get a result...
Best regards to all.
David.

Morning All

@Tony, Mark and Paul

Thanks for suggestions and support, I did use the CuPSol high temp soft solder to attach the rim and it does seem to have done the job, here's the wheel:



It's needing a bolt through the dash to make it sit correctly at the right angle, but its going for chroming first.Here's the new next to the old wheel:[size=78%]



And now I'm preparing to send off all the fabricated parts to be chromed.  This has just been sent out to get quotes:



Once I get some prices, I'll let you know the outcome...

Best regards to all.

Hi David.


For easier future Silver Soldering get some Vermiculite slabs as used to line wood burning stoves.


Also, a small Mapp Gas torch is best for our small work, look at this one.....https://www.ebay.co.uk/itm/303276421714?hash=item469caef252:g:AfwAAOSwroVdeTP7


It has a nozzle only 9mm diameter, very controllable with spark ignition, for Mapp Gas only and will easily heat / melt any metal that we use even the thicker stuff.

Hi Mike


That does look like a good torch. I have the Proxxon for fine work, and a larger propane, but it's too much... As I now know...


I've sent the items off for chroming. I've used


https://www.chromefix.co.uk/


Not cheap, but hoping for a good result.


I'm starting to add the amati deck fittings. Some are OK, but some a bit crude. The machining on the filler caps is dire. Am trying to polish without removing too much of the surface chrome.


Best regards
David.

Afternoon All


I've started to add the kit supplied deck fittings to the Aquarama.  There are four deck vents, two facing forward, two aft.  I'm not too happy about just glueing them on so have drilled a shallow 1.5mm hole in the centre and epoxied a short length of 1.5mm brass rod, so I can drill the deck and insert the rod with epoxy, just a bit more of a firm connection.





And the aft facing vents in place:





Added the side vents too, three 1.5mm SS screws either side and some 15m epoxy:





Can't wait for the rubbing strips to come back chromed and get them back on...


Best regards to all.
David.

Evening All

More deck hardware added today, used masking tape to mark out and left it on while pilot hole drilled by hand:








I drilled a few close holes (is it a hole if it doesn't go all the way through..?) to give the epoxy some bite on the deck where the cleats are placed, they are too small to add locating rods:



And the fore deck:



And with the tape removed, and the hardware epoxied in place:






And the Riva pennant.  I ordered one from CMB, I was a bit concerned as the piece of material it's supplied on was fraying at the edges.  I've used some UHU fabric glue at the edges of the pennant, then cut it out from the larger fabric square, the fabric glue is quite light and dries transparent.  Hope it seals the edges enough to avoid fraying but still lets the pennant 'flutter' underway, we'll see...

Seems a major step to be adding the deck fittings.  Makes the boat look a lot closer to being ready.

My nemesis remains the upholstery...
Best regards to all.
David.

It is a major step David and very close to the conclusion of an excellent build, with just the chromed pieces to fit then.

And then you can start the whole process over again!!

Thanks Both, hope it'll be getting wet soon too..!


I have a question...  The etched parts, some require bending to shape.





Which way to bend..?  There's a crease, does one bend towards the crease..? I'd have thought that's correct but thought I'd ask...


Thanks in advance.
David.

Hi David


This is the wiper blade?  I bent away as the other way might put too much strain on the metal.  I used a thin piece of metal to fold it in a vice. Quite a fiddle.

Hi Paul

Thanks for that, I've not taken action yet on the wiper blades, will let you know how I get on.

I'm continuing adding detail:





Waiting for the chromed parts to come back...



Rear view / skier mirror installed, the compass, and the all important tray to secure sunglasses...



I think these are engine room vents, I've seen some full sized boats have the inside of the vents painted red, and it with with my colour scheme, so I painted them red too.



Will be tackling some additional detail this week, and the pesky upholstery...

Best regards to all.
David.

Added the cushions around the coaming. Joined the three cushions and Added some tension to the lower edge to add a curve to match the deck shape.








Then attached with double sided tape. And screwed through the short metal strips. 1.2mm x 8mm.











Still waiting on the chromed parts, hopefully see them this coming week...


Regards to all.

3D printed a clamp for the batteries, a cut out to go over the keel. And a hole down the centre to allow a bolt to hold the clamp to an M3 threaded brass inserted in the keel.  A couple of foam pads added.








And while I don't intend to have the Aquarama out when it's raining... I have added the windscreen wipers, just in case...

Morning All
Plenty of work done on the upholstery...  Only to be ripped apart as it looked rubbish. This is best version of the bench seat at the moment, still not happy with it. But learning a lot...





And in position. Its OK as long as you don't get too close...








Had an update from the chroming company, should have the parts back second half of this week.


Best regards to all.
David.

Morning All


Before I report the upholstery progress, how about these from Veritas, a birthday gift:





80mm long, and made from same steel as larger chisels...


Back to the upholstery, the forward seats have been improved, a single wrap of faux leather to cover a lot of joins...














And this is it before any piping is added:





Also decided to modify the bench seat to add more red, and piping...





And (for Mark) happier to show the detailing this time..!





And in place, with piping added to drivers seat:

















Need to finish the passenger seat piping, and add the seat detail:





Still waiting on the chromed parts to be returned...


Best regards to all.
David.

Like the chisels.  The seats have come on some way and are now matching the rest of the quality build.  Looking good.
