Cheers Chris.

If you remember we had a chat at EC one Saturday morning.

Got to sort the lay ups next.

Regarding your 50cc racer you should talk a guy by the name of Dave Boothroyd, he lives near me in Biddulph and ran a company call 2cycle developments,

he was a lecturer in marine engineering and raced, rebuilt and tuned 80cc single cylinder 2t gp bikes, really knows his stuff about 2t singles and made one off expansion pipes for them.

Hi Chris
Yes I remember having a chat , we are having a good year with the bike and my rider took 3.5 secs of the lap record first time out but he has been offered a ride in BSB this weekend so I have  another rider for our next meeting on Sunday. It looks like you have the carbon bug  Smile

Can i just say photobucket is a real pain and has a mind of its own, if the pictures are of different sizes and orientation
then please forgive me, I've spent hours trying to upload and edit only to find it saves what ever it chooses. 
 

Still not made the time to make the the seat mould but I've polished the seat and started to cut some of the flanges,
In the mean time I set up to make the rear hugger and front mudguard.

Rear Hugger.

Bagged the hugger having laid the mould with one 200grm pro carbon,
two layers 200grm twill, peel ply and mesh.
Through connectors are doing the business and stopping the micro leaks. 
  

Resin infusing and looking good.


Infusion finished, everything went as planed and i was looking forward to breaking the part out.


RIGHT, again three slight pulls in the part.
Paul at EC kindly de moulded the part and I was a little miffed at the marks as I'd been 
super careful when I laid everything up.
  

As soon as I went through the process with Paul and told him I'd used the pro carbon 
he stopped me and explained that this was the probable cause of weave pulls.



TRICKS OF THE TRADE.

You learn every time you touch this stuff.
Paul showed me a little trick with the pro carbon.
It doesn't like compound curves and so a little heat applied using a hot air gun is needed.
Lay the CF and then gently warm it with the heat gun, this softens it enough to get 
a nice drape with no pulls.
Will it work!!!!

Front Mudguard.

With my new found skills I got stuck in.
I have used the two different types of mesh, the soft is VERY difficult to remove 
so i only used it in the square centre of the mudguard.
All bagged up ready for resin.


Resin infusing.
You can see the different flow rate of the different mash types,
soft mesh is in the middle.


Another picture later on during the infusion, you can see that the soft mesh wets out 
slower than the normal mesh by the white spot in the middle.


Finally a part that im 100% happy with!


Mudguard looks great.
Again I'm learning and moving in the right direction.
Paul has kindly offered to do another hugger with me to see if he can 
iron out a few of my bad habits, 
Where else would you get that sort of service.

Nose cone mould is polished so I will be making the finished part in the next week or so.

Chris.

Thanks guys, I'm new to this so still learning, glad you like the stuff so far.

I had set up to do the nosecone over the weekend but I decided to put some extra polishing time in to the mould first.

I will need to cut the CF in order to fit the mould so I will post up all the cuts as fitted and maybe some of the more experienced on the forum and give their views on the orientation of cloth before I commit.

thanks for all the great images once again! 
To add a little remark about the polishing of the mould, here is something I've found out...
I've stopped polishing my mould till a high gloss. It's always nice to get a super shinny part popping out of you mould but I've found out 
either way I have to sand the part after demoulding to prepare it for clearcoat...So I'm happy enough with a 800 grid sanded mould instead of a high gloss mould
for my parts Smile

That's interesting leaving the mould keyed.

I think as I how some experience of working with auto paint I'm looking to get the part perfectly finished so I can then simply scotch pad and clear coat,

I want to do as little work to the finished part as possible.

I will certainly have a look at your method of working, got a small infill to make so I shall try it straight off the grit.

The result is still better than a scotch pad with 800grid moulds.
So parts are coming out of the mould perfectly (but not with the highgloss you would expect from grid 3000 moulds) 
But I dont care because I mostly sand them with a 320-400 before clear...

So perfect results out of the gun without spending to much time on the mould (the mould is perfect without any errors, but just not at a high gloss stage)
