Carbon question.......

[wedge]

i think just the front half will do....like everyone says is just the front that gets the ding..plus 3tj fram is rather nice so why cover it all up.

do yzf750 fit????

[morepower]

Well loads to think about....

I will do full length moulds and if shorter covers are needed I can just make them smaller either by cutting them down or just laying up less of the mould and trimming them up..... I do quite like the full cover at times so by doing it as a full cover people have the option to have it how they want.....



Not got a hugger as a stock item to alter... But if I can get hold of something I can make something to suit.... I will look into it... So again if someone has one let me know please....

Engine case covers are something I have been looking into.. The down side is the cost of the mould as you need two parts and both need to take massive forces as the only real way to get a good cover and protection is to use a press mould that clamps the material and resin between the two faces and gives a part as strong as autoclaved parts and is a perfect fit everytime... So leave that one with me too.....

No idea if the FZR750 ones fit.... But if they do.... then the 400 ones can be sold to fit the 750 too..... haha...

No update today on the new mould..... Had a nightmare day and had to go and get some release chemicals and pastes..... I had 4 parts lock in the moulds I was using so have to re-polish and re-surface them.... Not happy as 3 of the 4 parts are scrapped..... Oppps....... But will have an update tomorrow as I have got the left hand side of the swing arm ready for gel coat....

The FZR 750 is an OW01 although there might have been a jap only model FZR1000 Genesis.

Morepower - would you stuff for the Bimota Owners ??? They want a copy of the race heat shield on my SB6





The silver underneath is a heat reflecting foil (I think), if it's possible let me know the min number

How many want them??? I can copy it no problem.... I have silver heat reflective foil anyway so that is simple... I would need to figure out the size of the part and how much material is needed... But I dont think it is too hard to do...If you are not using it at the moment send it over and just see how many are wanted... I would just cover the cost of the mould over how many want them.... I think the mould would cost between £150 and £200 to make if I have to send it out to the pattern maker and about half that if I can do it easily...

Is it structural? or just cosmetic? I need to know as cosmetic could be done with polyester resins and a gloss finish.. If it is structural then Epoxy resins are better and I can probably get a dry pre-preg look to the part too....
Similar to the box I made for Tom on the PB forum... I just used a tupperware tub as the mould for this and it was one of my first parts so the finish is not as good as I am getting now.... But gives you an idea of a dry look epoxy part...

I must admit when you mentioned polyester resin my eyebrows raised, to be honest through in the couple of years i've been dicking about with glass fibre i've noticed the quality of stuff, resins particulary, go up massively. And you can't really argue with the finish your getting, it looks really good. Can't wait to see what you do with pre preg. In fact i'm more interested to see the oven when thats finished, sounds incredible.
Keep it up mp, by the looks of the posts you're getting your gona be busy!

cheers

Thanks Martin...
Polyester resins can be very different, I learned that the hard way.... It is not always about cost either.. Gel coats and clarity vary and even the one I had been sold by the pattern maker to try is not as clear as some of the epoxy resins used in high gloss pre-pregs.. But by mixing some resins and trial and error (luckily by increasing the ratio the trial didnt have too many errors) the clarity improved. I started with a general puropse kit with general purpose resins you dont know what brand or which one of that brand you are getting. So although it was a start you can never be sure if what you are getting will be the same if they find a better deal so it is better to know what you have. It does seem many sell a resin called Encore 30 which is too thick and has a hue to it when cured. But the suppliers just dont tell you. Most general purpose resins are sold with glass fibre in mind and to be mixed with a pigment so clarity is not an issue. It is finding a resin thin enough to remove all the tiny air bubbles but has clarity for carbon.

The oven... Hmmm... I have to move 7 bikes out of the small workshop as I am going to use that space for my laminating workshop and put an oven that is about 8 feet deep in there.

To be honest the reason I have started to do carbon is like you guys have found no one wants to do the things that are a bit odd or not too popular. OK it means the stuff we want would cost a bit more as it will never be mass market but it is still worth doing and if there is a reputation for doing things like this is built on there should be more than enough work for a very small business to make a reasonable living from it.. So lets see what these FZR parts are like and if people want them and like them... Brilliant...

It's non structural and simply bolts onto the exhaust - you don't see it because it's under the bodywork so it doesn't need to be concours. I'm trying to gauge numbers before I send it to you but if I say 10 and that price is ok I might just commission it anyway and punt out the remainder.

[morepower]

Just need a size to know how much material is needed to make it... length and width if you can get round the sides too.. As long as I have an idea of what the laid out sheet would need to be I can sort something out.. For cheapness I can do carbon surface with a glass fiber in a sandwich between the carbon. I know one side will have heat reflective tape but if it is not carbon on both sides the glass will expand differently and twist the part or crack. But using a layer of glass between the carbon will make it a bit thicker and stonger to stop it cracking when it is bolted on.. With all 3 layers it will be no more than 1mm thick anyway so it will be light.

Ok - I'll get to measure it but not tonight (obviously)
