JJ Do you have the same problem with Brian?  Oh no, I forgot, your problem is mouse poo in the dash.

If it’s a choice between having the car red or the flies, I’ll keep the flies.

Phil.  The show this weekend was Chetwynd Deer Park.  With all the deer poo around there were plenty of (big) flies around.  Guess who’s car they found.  There was also a tree at the end of the club pitch with some sort of wasp or bee nest in it but I didn’t go close enough to find out exactly what sort.  We left them alone and they left alone.  A win all round.

I’m looking for some sort of fly repellent wax polish, so if you’ve got any idea?

Well, did the carbon fibre test piece work over the entire weekend?  Not entirely.  On the West Coast there are two “ box sections” to stiffen the front panel.  It was one of these I was using to locate the test piece but it’s a bit tight to fit the test piece as it makes it difficult to close the bonnet and there is a witness mark on the underside of the bonnet inner skin so rather than risk any damage that idea needs revision.

I’ve spoken to Brian and he said I could reduce the height of the rib things or even remove them if I replace the strength in the front panel.

So that’s the next iteration of the job.  We’ll get there in the end and the test piece did look good in the sun.  With the warmer weather I’m hoping the CF will cure quick enough.

Yeh, it’s only an exhaust pipe.  I can go down the road to the local exhaust place and get one of those. 

Err, no.  It doesn’t work like that.  It’s a one off.  That means somebody has to design it.  Not a design team, someONE has to do it.  Then it has to be made.  Not factory made.  It’s a ONE off.  Then some people make disparaging remarks about it “only being a replica”. They just don’t understand.

Keep up the outstanding work.  It’s a credit to the kit car ( not a good name I know) community.

Red hot.  Doncaster.  Count the Furrari in and I’ll see you at Stoneleigh ( the Furrari is the YELLOW West Coast) about booking a stand at Doncaster.

Fan arrived and ducting made ( no pics, 'cos it’s not pretty).  I decided to wire the fan into the pump switch.  What I learnt from this is that unplugging the soldering iron does not isolate the pump.  That made me jump, but it’s not the first time I’ve joined myself to the mains.  Will I never learn.
I’ve checked the oil in the pump and there is no signs of burning, the oil is still clear and the oil mist doesn’t smell of burnt oil so I can only assume it’s oil vapour not not burnt oil.  If my fan arrangement doesn’t solve the mist problem I’ll have to build a catch tank to filter the exhausting oil mist.  Not a big job and won’t require me to work with mains electric so I’ll be safe.

Anyway the test piece looks very good now that I can hold a decent vacuum, but I’m still not 100% happy with it on the vertical face, but the horizontal surfaces are really impressive.  After the show at Chetwynd Park this weekend I’ll try putting a 45 degree bevel on the vertical face and re-skin it.  I’m optimistic that I can achieve the overall finish I’m looking for.  It’s a long slow job, and a steep learning curve, but with the warmer weather it should reduce curing times from 2-3 days down to 1.

I’ll bring entry forms with me to Stoneleigh for Doncaster so we can book a stand.  We’ve usually had good weather for this show.  It did rain one morning and I have a unique photo.  Madman’s car with its roof up.  Oh no, that was the show I lent him my big umbrella to cover his seat.

JJ.  Good to hear your well enough to come to the show.  See you on the Monday.  Will you be bringing any of the mice I’ve been hearing about.

Look after yourself

Mick

More from the Composite Shop.

I’ve got one ore two ideas I want to put on the car, but I want to experiment first.  How to do these things are not on YouTube.

First the former.  I will be using ABS to give me the shape I want, but it’s only 2mm thick, so how do I join it together.  Tried super glue.  Total failure.  Tried acetone.  Almost total failure.  So I made up a slurry of scrap ABS and acetone and used that.  Almost worked and with a bit of triangle shape as reinforcement, success.  I think having it as a slurry it fills in any small voids from the sanding, giving more surface to bond.

Then to vacuum bagging.  Due to its shape it has to be vacuum bagged but following all the rules on how to do this has given me mixed results, and I’ve never been able to draw more than 60% vacuum which is not enough for this application.  Instead of using the approved bonding stuff (a bit like window seal stuff) I held the bagging down with the engineers go-to.  Gaffa tape.  Well what a difference.  90% vacuum and the bag pulled straight down, only a small leak from the vacuum pipe and I think I know how to fix this next time.

So it’s all sorted.  Err, no.  After running for about an hour the pump is to hot too touch and there’s smoke coming out of the exhaust port.  The CF forum shows this is not unusual with Chineseum pumps, but industrial units are between four and five times the price.
I’ve ordered a fan and I’ve got lots of foam board to I’ll make up some ducting to blow cold air onto the pump.

I’m reasonably happy with the product I got out but I think I can improve on it if I can run the pump longer.  The sample will be on test this weekend at Chetwind Park so we'll see how it performs before we go for the full scale bits.

Nubodi. I’ll be on the DNAOC pitch.  YELLOW ( the proper colour for a Furrari) West Coast.

Nubodi.  I can do you a set of carbon fibre calipurrs, no metal work as i only made it for myself as a replacement for one of mine broken by the local potholes.  Discs, I’ve never tried.  I can probably do them but I would have to take advise on the finish, and again no metal work but you could probably get a set locally laser cut.  The alternative is sone stainless steel ones, again laser cut.
I will have one with me at Stoneleigh if you want a look. I will bring my disc as well as last year there was an FG man there who might be able to help.

Headlights is more of a problem as the California ones don’t fit.  No idea on that.

Best of luck Mate.

Just a pic of the CF on the side of the headlight.

A bit I missed was masking up for about 200 yards around the headlight, positioning the skirt into place and give it a coat of adhesive so I could put masking tape on it and remove it without pulling threads of CF off.

As the 1/2” strip of epoxy and CF had cured I moved on.  I dropped the headlight back in, poked the CF down past the edge of the surround area, marked and cut it.  The 1/2” land on the headlight is not vertical but at bit of angle so it slopes inwards and only hangs vertically after this.  I’ve used CAD/CAM (cardboard aided design and manufacturing) to make some, if they were metal you would call angle brackets.  I taped a couple of these to the surround and the now vertical face of the CF with about about an inch between them.  I wetted out in between the tape and the brackets and left it to cure.

When this epoxy had cured to the dry end of the beta stage I removed the brackets and tape so it doesn’t bond to the CF.  We'll see in the morning to see how it looks.  It’s not complete flat as the 1/2” land changes shape as it follows the shape of the headlight unit.

No pics 'cos all you can see is a headlight covered in masking tape.

Following on from “Furrari Build”  I’ve removed the headlight.  Given DNAs foresight the headlight unit is retained by one 14mm nut accessed from the engine bay and the wiring is all on superseal plugs so it’s out in seconds.  First job is to cover the plastic cover with a layer of masking tape so I don’t scratch it or get epoxy on it.

Should I do a wet lay up or vacuum bag?  Looking at it I realised that nether of these will work so I’m going to have to try something different and that I’ve never heard of being done, a hanging screen.

Second job is to cut a piece of CF bigger than you need and give it a LIGHT coat of adhesive.  This stops it fraying.  Give it 10 or 15 mins to flash off.  Then cut it to shape where it meets the cover.

On to the epoxy resin.  I gave the relevant surface a coat of black epoxy resin.  When this reached the beta stage ( tacky but doesn’t come off on your fingers) I put a layer of clear resin about 1/2” wide on the lip just below the start of the plastic cover and put the CF on it, and wetted this out.  Left it to cure.

When this reached the beta stage I removed the first couple of rows of masking tape so ithe resin doesn’t bond to the tape or the plastic cover.

That’s it for now, given the current ( in CF terms) low temperature I’ll give this a couple of days to fully cure (and give me more time to figure out how to do it).

As I’m making this up as I go wish me luck.  No pics as it’s only a pile of masking tape and a bit of CF sitting in a heap.
