The stuff dreams are made of

WHERE DO I BUY ONE OF THOSE PRIMARY CASES FROM ??????

Those primary cases no longer exist.

There were only ever 3 of them made.

Rubbing salt into my open wounds ...

More pictures please GP. Glenn. P.S. I have a friend who builds planes that have won many air speed races using Carbon Fiber & he likes to play around with it, he makes boogie boards to surf on etc. if there was demand he might make some Norton stuff...

There's always a demand somewhere.

I'd be willing to lend my set for mold-making, if I could get them back along with a set of clones...

I doubt he'd get rich on such bits, but there must surely be ample demand to make an interesting project for him!
I'm quite sure that if the quality is right, just posting pictures on here would yield good sales!

Hi Eddy

Speak to Chris Alty

Carbon Fibre Works offers a bespoke manufacturing service for all your carbon fibre needs. We specialise in one off and low volume work using the latest techniques and a range of Carbon/Kevlar and resins to suit your specific requirements.
Carbon fibre components can offer you a significant weight saving over other materials and also increased strength. Kevlar can also be used if required to increase the impact resistance of components. Lead times can vary depending on the component, but a rough guide would be a full fairing from receipt of an order to delivery of approximately 4 weeks. We can manufacture almost any item for your race bike in Carbon/Kevlar. All correspondence will be in the strictest confidence.
Typical components: fairing, mud guards, nose cones, shark fins, mounting brackets, oil catch tanks/trays and seats.
Website coming soon.

Here is a link to the CRMC website have a look at what Chris has produced. I especially love Pauls "support" Quality stuff.
And a really nice bloke. Tell him I sent you & he will add a bit more to the price

all the best Chris

Carbon fibre , or carbon look ? .
This is a low stress part , so it would be a waste making it in real carbon .
Epoxy will do just fine . Shouldn't be to hard to make .
I believe someone sells polyester copies .

Wouldn't carbon fiber be lighter? a few grams here and there... you know what I mean :wink:

Aerogel metal filler with a thin graphene layer wrap would be the lightest strongest most expensive. Clubman Racer site lists a plastic primary cover but think they sold out long ago. Could have em made in ole Bakolite then hydro dipped in C-fiber pattern. One would definitely feel the improvement w/o the DS mass of case and cover and couple-300 bux would be cheap for the loss.

You've mentioned epoxy several times. Can you describe this in more detail? Do you mean glass fiber re-enforced epoxy or something else?

The chaincase can and usually does do several things
1/ Keeps oil in if it should
2/ Keeps external stuff, dust, rocks, small furry animals etc out
3/ Offers an element of safety to the rider or passers by. Have you ever seen a finger that has got wrapped up in a primary chain?
4/ Has a chance of containing some of the bits if there is a catastrophic failure

None of these are particularly difficult. Whilst carbon fibre offers the "wow" factor visually, carbon cloth is a lot more expensive compared to a good quality glass cloth. I've just checked some prices; 5.8oz glass cloth off of a 50" wide roll is US$8.45 per yard, from the same shop 5.9oz carbon off of a 50" roll is US$16.95 a foot. That makes carbon approx 5 times the price of glass cloth.
Epoxy is the only stuff to laminate such a thing from. Polyester resin should only be used for fishponds and even then, only when there is no requirement for it to be watertight. It's heavy, weak, shrinks hugely and is basically not appropriate in any modern engineered product.
So, my suggestion would be offer the "standard" composite chaincase from glass/epoxy and a deluxe version from carbon/epoxy. If you really wanted to get the max benefit you could have a vacuum bagged version, where the epoxy is minimised and so produces a super light version, either in glass or carbon.
onwards and upwards as Matt might say

wakeup

Would have to be an act of love and desperation as like market would be saturated after couple dozen sold over a few years.

Absolutely!

Where is a picture of the inside of both ?
Carbon fibre alternator posts ? or carbon wrapped stock primary covers.
Plenty of folk do fuel tanks in carbon fibre cloth wrap

Mine were made for the VR880, so no stator posts.

Also has the cut-out for Spyke starter.

diy carbon fiber. Now comes with various resins pre-applied but must be kept refrigerated then warmed right before use and with vacuum assist can come out as good as professional with deep clear coat. Scan some fo these.

Looks neat and descent tyre coverage too.
It's satisfying starting from an idea then model, mold and product.
Good way to spend a weekend Ludwig. But then I'd want to take Monday off and go for a ride.
