Racers and restorers,
Just throwing it out there -
Is there a brand, a part, a bit, a part or a widget that is stopping us finishing the race, the project, the what we had as a kid?????

Money
-
Motivation a system of organisation so i can actually finish somthing ;D
-
Yep, A pair of Ohlins twinshocks and front forks that I paid for 6 fu..ing months ago.
Am I being unreasonable....maybe
-
A Jones DT1 clutch cover.
-
Rm500 rod kit under $700 :P
-
a set of rms125 .5 thin rings,they seem like trying to find rockin horse shite ;D
-
NOS clutch basket for my 1979 Suzuki RM 125 would be nice.
-
The $2,500 dollar FOX forks advertised on gumtree....
Trouble is i dont have an 78 79 elsinore to bolt them up too. ;D
-
Or the works SHOWA forks made out of magnesium thats
on marks swap meet.
83 Honda Mugen 250 for sale on ebay over in Europe
also comes to mind. :P
-
A Jones DT1 clutch cover.
there was one on US evilbay last week . My dream part is a Jones Frame .

This is your lucky day Andrew ;) i can help you with both ;D

lovely, keep them parts coming.
Im looking for a part I could remake or modify to help everyone in the vmx scene.

Carl,
It would be quite a big project but if someone made a run of 1984 CR250RE waterpump housings out of alumnium i'm sure they could make a fortune

What do you think a billet housing would sell for??
I can get them made no probs but to just make one will cost too much.
Also if any one has a case I can borrow so it can get it modeled it would help save a bit as they are $250 + for a rooted one as I don't really want to pull mine apart

Hey Rookie. These tanks appeared on the works Kawasakis at the 1979 Trans USA and were used throughout 1980. The spark plug "dent" reference is to a photo caption from Motocross Action in 1980. Trevor Williams SR440 had one of these tanks. I think his split open a few times. Below is an example on Jeff Ward's bike at the 1979 Anaheim Supercross.

Just yesterday I was listening to a very interesting story on ABC radio about 3d scanners/printers and all the associated technology. They can "print" in a variety of materials, and the prices are getting cheaper even as the technology gets more advanced.
-
That's a cool lookin bit of kit Rod, in the unlikely event I ever stumble across one I shall keep you in mind! Have you considered taking some pictures of this item to a pro fibre glasser along with some mounting dimensions to see if they could replicate it from eye? There will be a gell coat to match so colour won't be an issue, yeah it might cost $1000 or so to get it made but if such a rare item ever came up for sale I can't imagine it selling for much less that! :( Plus that item will be in "as is" condition and not new.
Just a thought.
Cheers, Brendan

id put my hand for the alloy cr250 clutch cover if you make some

Last week on one of those horrible commercial TV current affairs programs they made a gun using one of these 3D computers and actually fired it. Aldous Huxley's 'Brave New World' is fast becoming a reality.

I would guess KJ222 would also be in the line for one of those

A Thor swingarm for my 77RM125 project?

I've thought about it Brendan and it may end up being the only option. There is a guy in Japan who makes fibreglass replicas of some of the earlier twinshock model works Kawasaki tanks, but not this particular model. I've got two of his tanks and they are real nice.

But it doesn't just print all by itself, you have to 3D scan the item or have 3D files drawn up. THAT is where the $$ come in. If your handy with Solidworks, Catia or Pro E it will be a doddle, if not ......................
For something like a clutch cover or a case half the billet option to make more than 5 is too expensive. Casting is far more cost effective and with 3D printing making the sand cores.

I understand what you're saying, but it's early days (relatively), imagine where this technology will be in a few years.
-
yes the 3D printers are the future, I've heard there are some new printers that print in metal. (stainless and titanium) which is pretty danm cool.
One of the problems with the plastic printing is they are very brittle but most likely could be used for a mould.

It's our 21st year working with the technology and the changes in that time are truly impressive. Some of the light weight optimised parts we are making will blow your mind..... 3D printing (additive manufacture) will change the way that we live, but will always struggle to complete against convention processes to make conventional parts.

I think someone in the UK is making them.....(no not me). Have a look at MX Trax. No wanting to dampen the fire, but why do the job twice? Go for something that hasn't been done yet. Finding out what people want and need (and will pay for) is the challenge!

You heard right. Google EOS, ARCAM and Renishaw. Build volumes are limited (ball park 220mm cubed) and cost can be a challenge, so you have to be sure of what you are doing. Approx 8 off the shelf materials to choose from (plenty being developed) New developments are published weekly. It's exciting times and of course you only read about what they want you to know about........ Early adopters are F1 and Aerospace. At the other end of the scale, you can buy a machine for about £1000. Technology is FDM (fused deposition moulding) Think MIG welding plastic in 2D layers, layer by layer by layer. Fine for a school project, no place on a race bike!
-
I wouldn't mind a cylinder head for an air-cooled 510 Husqvarna. I don't know if someone could run off a batch of these with a 3D printer.

You can use 3D printing for moulds but you cant make anything that needs precise tolerance because of shrinkage that is never even. You always needs to finish with machining.
-
We sell the 3D printers, but there only good really for stuff like plastic, wax shapes etc as the medium has to flow through the print heads, then it just builds up layers as the heads pass over it in a cross section. Beinag able to pass liquid metal type media will be when it comes into some real uses.
The interesting thing i seen talk about lately is the food machine, it has the core powdered "materials" by basic elements. and when dispensed in the right order/quanity etc should be able to make up a stack of differant items. They are currenlty working on it being able to " print out" a pizza.

Firko look at the bright side , if they can print a pizza then they can probably fax one too cutting down on delivery time and tips ;)
They will probably be able to email one soon , but I don't like spam on my pizzas ;D

Wonder how long before I can print an expansion chamber out instead of spending hours welding the bastards up.
Tea, Earl Grey, hot
Beam me up Scotty

yes slakewell, if i was to print a plastic mould it would be slightly oversize in certain places like gasket faces and bolt holes to then machine out later.
I personally would rather making them from billet but it would be too much waste material, time and cost. i guess ill have to do some more research on how these can be made.
Carl
-
how about an alloy muffler for an AW 250 ;D

One problem is the hardness of the alloy, whilst it east to buy stock of say 7000 series alloy and then machine it spec it quite another to have a foundry pour your moulds of similar quality.

Dunlop K88 (4.50x18) and K139 tyres

Good old fashion square block trials universal tyres in a range of sizes (2.75 x 19, 3.00 x 19, 3.00 x 18 and 4.50 x 18) so I can have some descent rubber on my collection of old Yamaha trail bikes.

Beinag able to pass liquid metal type media will be when it comes into some real uses.
So use a powder based system and a laser (EOS) or electron beam (ARCAM) rather than jet technology. We use powder bed technology to make some amazing parts for our Industry. Need to use the right tool for the job.

They have already made a machine that will 3D print chocolate! It looks good, but tastes awful as the elevated temperature of the chocolate causes all the nice flavours to be lost.
Additive Manufacture (A-M) is not the answers to our prayers, it is another tool that will help make things that were previously unmakable. If you need a 510 cylinder head, you need a foundry / machine shop. If you need a replacement plastic door handle for your caravan, go to the OEM and buy one for £3. If you need a gear change meachanism that is 75% lighter than the original part, is half the size, made of one part not 6 and also serves 5 other functions then you may want to consider additive manufacture. Some of the shapes that can be made cant be produced via conventional means. The structures are organic as if nature designed them that way. People tell us they look like parts out if the Alien Movie.
Typically manufacturing evolves as tweaks are made to processed. A-M is a revolution that will change the way we look at the world. It wont mean that end to existing processes, but will allow us to design and manufacture things that were previously unmakeable.
It will always struggle to compete with existing processes. So if you need a cylinder head, go to the cyclinder head maker. Where it will always win is with complex, multifunctional, light weight shapes.
As the technology evolves it is inevitable that costs will come down and build volumes (the size of part you can make) will increase (e.g there is a 500mm3 on the cards now)
I think there are verty exciting times ahead.
........
At the other end of the scale, cheap printers are getting cheaper and to be fair better. There will come a time when hoem PCs will come with one. I suspect it will be a freebee that uses very expensive cartridges!!!!
I am not sure about a pizza machine. Call me old fashioned, but I would prefer it made the traditional way!

i think they are developing a GMC genetic clone for that ..... but they are having trouble with the "witty humour" & KDX fetish options

By the sounds of it, my local Pizza Emporium has already perfected the process.... ::) ::) ::)

Update is Carl is looking at water cooled Honda CR clutch covers to fix the impeller rot issue. Should be getting a sample from Ken # 222 from Heaven to continue the adventure.

Another guy from Heaven is already onto it

yes im aware of that ted, im going about it a different way and could benefit a lot in price to what someone else is doing.

Any GMC clone will always have inherent intermittent problems. :D
