Oh arse

Oh arse

As one of my fellow directors says "the only people who don't make mistakes are the ones who aren't doing anything...".

It's not that big a deal really; a couple of hours to strip the bike down, a couple of hours to fettle the frame and make the parts needed, a couple of hours to weld them in and then hand it over to the powder coater. And it offers the opportunity to do a couple of other jobs on the frame.

The bike will be back to where it was before this came to light in two weeks, which aligns with when the airbox is due to be ready so it's not holding the project up.....at the moment.

Frame's all welded and due back from powder coat on Friday.

Air box and tank edge protectors have been completed by Rook Composites, tank top/back/knee pocket protector due to be finished over the weekend...

Proper shiny.

Getting close now

What an awesome thread!!!

And there I was thinking I was hardcore contemplating fitting a baffle to my sc project s1

In other news, I've fallen down the rabbit hole that is the DVLA....

I sent off the original V5 to notify the DVLA of the change in colour, the cc increase (1078 to 1098) and the change in engine number and I included the email receipt I got from the engine seller, a member on a Ducati forum.

I've had a new V5 issued, with the colour changed but with the cc and engine number unchanged. Separately I've had a letter from the DVLA saying the evidence I supplied was insufficient as the receipt for the engine was not on headed paper or from a registered business.

The letter went on to advise on the accepted forms of evidence that they would accept in order to update the V5, the simplest of which - in theory - is an inspection report from an organisation "such as the AA or RAC". Having spoken to both, neither has a clue as to what the DVLA want...

I think I'm going to start with the simplest option first of all and have a chat with Cornerspeed Ducati and see if they can do me a simple inspection report confirming the engine details as fitted to the bike now.

At least, when the bike is road ready, I can ride it on the road without fear of immediate trouble as the colour will be correct and the chances of the engine number being checked by the polis in the event of a stop are pretty slim. But I want to get everything legit as if it does get looked at in more detail there's points and fines lurking there...

I've just sorted out the insurance, which was one of those looking through your fingers kind of moments....

The Multistrada, in its original form, was insured with Bikesure and they also specialise in modified bikes so a few months ago I got them to quote for the bike with all mods declared. I was totally, scrupulously honest with everything that had been done and how much it would cost to replace and the quote I got was exactly the same as my current insurance costs.

I was sure that couldn't be right, I'd given them all the information they needed but insurance companies are notorious for seeking any excuse to not pay out/

So, I gave them a ring earlier and went through everything line by line. Engine? Yep, they've got that right. Frame? Check. Tank? Ah, here we go.

They'd got the replacement cost down as £700. Not £7,000.

There you go, now an extra £170 a year for all mods and a replacement value based on what it would cost me to build it again.

Not too bad at all.

Say what now....

This tank has cost you more than a 1098 ?

The current tank has, more by luck than judgement, cost me about £2,700 and my old YT Jeffsy.

However, those circumstances wouldn't exist again so if I were to go to a fabricator as a paying customer it would cost - if it were made in the same way - a minimum of £7,000.

I think I mentioned earlier in the thread that my 1st choice for the tank had been AP Metalcraft. None of this hand forming 70 or more panel sections and welding it together by eye, no sir. The make proper bucks and formers and use a 300 ton to press to form large sections from sheet and they make bespoke jigs so that the finished tank is 100% faithful to the original and if you order 10 of them you'll get 10 identical tanks. They make tanks for WSB, BSB and MotoGP.

£9,000 for the first tank from them, and that's with them keeping the bucks/formers/jigs etc. £11k if I wanted to own the tooling.

However, if the current tank were to be damaged beyond repair I'm pretty sure I'd rock up at I.Porter Ltd (@porter_jamie's brother's design/machining/fabrication business) and we'd work out how to machine a tank, in a manner similar to Kalex making their frames. With large machined sections welded together...

[weeksy]

Wow... just wow... i'm impressed and astounded by your comittment

[millemille]

Wow... just wow... i'm impressed and astounded by your desire to not have your wife find out that if the tank weren't made you'd have had a useless frame and a collection of parts that could never be a functioning motorbike again and you'd have been divorced in a heartbeat

Thanks...

£2700 - 7000 Holy moly!!

It's a good job you love it.

It might be shit! Who knows

Fucking hell, who's pissed on your bonfire?

Haven't you got a bridge to go and skulk under?

Lol easy tiger. It was supposed to be amusing

Got a call from the paint shop to come and have a look at the tank.

They've given it a thorough base burnishing/blasting and wanted to discuss the next steps as what happens next is different depending on what we decide.



The idea of fine media blasting and scotchbriting and leaving the tank in bare metal, just lacquered, is a non-starter. The surface finish of the tank is, in places, not good enough. There's some small creases that weren't visible before burnishing...



...and divots or pinholes (not all the way through) in welds that only became visible once the surface was burnished.

So, it's on to plan B. The main part of the tank will be filled and finished and then the whole thing will be painted silver and then hydrodipped in a brushed steel finish.

Some of the Yamaha MT's have a brushed metal finish tank, but I assume it's painted rather than hydro-dipped.

Look forward to seeing the finish!

The guy at the paint shop was talking about the silver air scoops on the Diavel, like the one below, and how they look like brushed aluminium but he's sure they are painted...



...so he's going to try hydrodipping first and if it's not right he's going to try an replicate the Ducati brushed aluminium paint finish. He thinks they paint them a satin silver and then scotchbrite them when dry and then lacquer them,

[Mr. Dazzle]

I've poked around 'special finish' paint in my old job...we had a paint shop to paint the composite bits we did for various supercar OEMs. We'd use their paint (people like McLaren don't let you buy their paint colours, you have to get it through them) and some of it was pretty wild...ISTR one colour took 7 steps to achieve. Ive also worked with https://www.silverstonepaint.co.uk/ on some properly cool colours/finishes.

You can certainly get "metal look" by spraying in the right way/direction and ive seen some metallic finishes with a distinct "grain" to them achieved by selective directional spraying. Never seen brushed, but google shows a few companies claiming they can do it.

I'd be surprised if Ducati are scotchbriting paint, simply cause it would be way too variable from bike to bike for an OEM to countenance.
