Folks,
Check out the link and see what Farrier is thinking about next.
F85SR

He has mentioned there may be a tall rig option too
which could be used if not sailing under the NZ 8.5m rule.

Either way it looks like it would be a great addition to his current stable of designs.
He just needs enough people interested to justify turning the concept into a reality.

Phill

I see that F85SR stands for Super Racer.
The way I see it, if you omit the curved board option and keep the larger cabin, you could have a cruiser that would put most racing craft to shame.
Just something to ponder over a rum or two.

Anyone interested in turning this concept into reality should let Ian know.
It would be a fun project.

Folks,
I just couldn't resist the attraction of this "concept" craft. F-85SR

So I've bitten the bullet and started to build the (F-85SR) Farrier 8.5metre Super Racer.

I have found personally that armed with the right attitude building can be nearly as much fun as sailing.
Well not quite but it can be a lot of fun and good quality and highly detailed plans make it so much easier to enjoy the build.
You can't get better plans than the ones Ian Farrier draws up.

A photo album has been created on Catsailor to file away pics of the build for anyone who may be interested.
I hope to keep adding pics as I go along.

So far the float frames have been cut out and the float bulkheads have been made.

I hope to get the strong back down next week so I can start on the floats.

Fun times ahead.
Regards,
Phill

Farriers just became sexy! I want one too..

Rolf,
I always try to build good looking boats. From the plans that I have received the F85SR really is a great looking boat.

All I have to do is build it and......

Phill

Don't you need to finish your current project

And also needs to build a couple of smaller boats as pay for his daughters kitchen
Hi Phill, Can you email me my computer died(insert swear words in any lanuage here)
Thanks Richard

I have not been able to get near the F85SR for several months because of some pressing issues of more importance. I know that is hard to believe.
Anyway I have posted a couple more pics and now hope to start making some real progress. My next step is to make an oven 600mm x 1200mm x 2400mm. I don't really need it to build the boat but it would be handy to have when heating large quantities of resin, post curing smaller components and heating foam so it can be shaped to the batten mould. The F85 is a good excuse to build toys that I can use in later projects.

I quickly threw an oven together today with the help of a couple of friends who dropped around to see what I was up to.
This is not the "all singing all dancing" oven that I want to build to post cure and rapid cure of components but something that will heat both sides of foam up to 1200mm x 450mm so I can start planking the floats. The oven has 3 configurations that will deliver either 78degC, 103degC or 120degC. I put a couple of test pieces of foam through it today and while the foam can be bent at 78 it is easier and has a much better memory at 103 deg C and above. So I'll go with the 103 deg C config and this should help the planking go smoothly and quickly.

I started planking the float hull with foam today. Started late this arvo because it was a great day for bike riding , 1 metre planked and 7 to go. .
I went down to the local supermarket and bought 3 x 5kg bags of rice. I'm using the rice as weights instead of point loading the foam with clamps.
The foam goes into the oven, comes out and goes onto the mould and the bags of rice go on top to hold the foam into shape while the screws are screwed in from the back.
It cost me $37 for the 15kg of rice but it seems to work rather well and we can eat the rice when done so it really didn't cost anything.

I'm rebating the foam with a rebate 10mm wide in each sheet and 5mm deep. Cutting the rebate is taking a bit of extra time but this helps to ensure the level of the adjacent sheets is the same and will hopefully help reduce the fairing.

I'm assembling dry and leaving a 5 to 7mm slot and will force bog into the gap to form the seal that will be needed when I'm applying a vacuum for the glassing.
I will probably take some more pics tomorrow.

Phill how about a post with some pictures on the design of the oven?

Les,
The oven is very simple. I ordered some fan heater from an electronics store a couple years back,. The were offerring 2kw heater for $15 ea. I ordered 5 of them and they sent me 10.
Each heater has 3 heating elements and a fan all wired separately.
I'm using 2 elements in each heater and the fans.
The oven is simply a box made from 33mm mdf on the top of a steel frame. (Normally used as a table.) Ply sides and a 9mm MDF botton. The are two timber rails inside to slide the foam in on.
The hot air is blown along the lower surface of the foam and then turns around and runs across the upper surface before it can exit out a slot just blow the 33mm mdf table.
A baffel is made up to help the heaters grab the already preheated air- heat it some more and it is driven back in. When the heaters are operating with out the baffel and only two elements running you get 78 deg C.
Insert the baffel and you get a bit over 100deg C - around 103 to 106.
Switch in the third element and you go over 120 dg C.
I have added some pics of the heaters used and the oven itself with others to my photo albumn.

Thanks Phill

The Float half is laminated with foam and will probably get its inside laminated next Monday. I've added a pic of the float and the left over foam to my albumn.

Hi Phill, The link http://www.geocities.com/phillbrander takes me to what seem to be a "404" page. Do you have a current link to your album?

Thanks
les

Les,
That is a blast from the past.
I put that stuff up back in the late 90s. Yahoo made changes and most of it went into the ether.
I had to move the pics to flickr. I don't even know if they are still there.

The album I was referring to was my album on catsailor.

F85SR Building

I hope this helps.

Phill

PS- how does one become a member of the - "Royal Society for Making Cool Stuff "

I laminated the inside of the float half today. Managed to pull 22.5 inches of mercury using the foam itself as one side of the vacuum membrane. I've added a couple pics. It did some maths and that is something like 53 tons of pressure over the surface on the hull. Nothing like a good vacuum.

It doesn't look like you used peel ply, bleeder, or breather.
Any reason why?
Did you put the sticky s*** on the outside?

Les,
The absorption fabric is black. Maybe that is misleading as the order of layers is foam screwed to the frame battens from the outside (screws miss penetrating through the foam by 3mm), bi-di glass(0/90), peel ply, perforated film to release the absorption fabric and then the black absorption fabric and then vacuum film.

I used slow hardener and given our temp at the time I would have had to run the vacuum pump for 15 hours so I covered the structure in black plastic , stuck a fan eater up one end and after 30 mins the temp of the structure stabilised at 40deg C. So with that temp I ran the vacuum for a little over 5 hours.
I have just started to strip the layers off and the laminate is looking great. After peeling all the layers off except the peel ply I took some pics and put them in my photo albumn.

Phill
