Hunton/ilmor Build - Page 19

Hi All,
Taped up the sides of the boat so that i could mark out the relevant positions for each duct and also provide protection from the base of the jigsaw. Once the holes were cut i used an electric drill with a ball ended cutter to machine out the foam between the double skinned areas which i then thoroughly washed with acetone,once the acetone had evaporated i bonded the inner and outer skins together with epoxy resin with filler powder added to make a bonding paste.I then used black tiger seal round the outer flange of the duct and then finished of the inside with more of the bonding paste.The front forward facing duct will provide fresh air flushing of the fuel tank compartment the larger rear facing duct will be connected to small inline fans ventilating the bilges underneath the engines.

Hi All,
Machined up some stainless steel 12mm countersunk screws to make additional cockpit drains.There are now no areas in the cockpit where water can collect.

Very impressed by your attantion to detail.

Hi All,
Made up all the pipework for the cockpit floor drains, this proved far more challenging than first anticipated:

As the fuel tank is twice the size of the standard 37 the gap between the bottom of the cockpit floor and the top of the tank is quite small and as Hunton had already fiitted the cockpit floor drains prior to installing the deck i couldn't get sufficient fall on the pipes to drain by gravity, so the solution was to remove the cockpit drains machine the thread back to the end of the locknut and then make up some elbows to slide up the inside of the remaining fitting.

Hi All,
Pictured below is the mounting box for the trim and tab buttons which are placed quite close to the edge of the steering wheel to enable all trim functions to be activated without moving your hands from the wheel. There will be other controls mounted more toward the centre of the box for making changes to the sensitivity and other base settings of the fly-by-wire steering system.All the buttons and switches will be totally waterproof and potted into the box.The trim and tab buttons are momentary with quite strong springs other controls for steering adjustment will be rotary.Once all the switch positions have been decided the box will be mirror polished before assembly onto the steering wheel.

Hi All,
Been drilling yet more holes for cockpit floor skin fittings and also the engine hatch recess drains, as they are both double skinned i machined out the balsa core and filled the recess with epoxy bonding paste, this serves two functions it stops water being able to penetrate the balsa and prevents you from pulling a depression into the side of the hull when you tighten the lock nut.Also linished all the machining marks out of the switch box before mounting to the steering wheel.

Hi All,
Removed both engines ready for the detailed finishing of the engine bay, have decidied to go for epoxy 2 pack paint instead of flo-coat as i think this will give me a better finish.

I'm so amazed by this projekt. Innovative, stylish and state of the art. Extremely impressive!

Sooner or later people are simply gonna run out of new ways to say 'oh my god, that's bloody amazing!!'

I think that happened a few pages ago!

Keep being amazed at the detail - it's going to be a boat that almost needs to stay dry - having said that it will stand up to use better than any other boat!

I especially like the "Innovative, stylish and state of the art" stick to operate the forklift

Says alot about the person behind the camera.

Hi All,
I have always thought my wife Carolyn to be a bit of "HOT STUFF" but this morning she took things a little too far!!

as she wanted to light some tealights to get rid of some cooking odours from the previous night the gas lighter required filling! during which lots of gas must have escaped and filled up the kitchen sink?? being totally unaware of this fact a fire ball erupted in the kitchen on the first ignition causing a severely singed dressing gown forehead and singed hair

at this point i was enjoying a quiet breakfast on the balcony until i heard the screams!!

i rushed into the kitchen by which time the flames had run out of propellant and extinguished themselves, Carolyn by this time was in a severe state of shock!!! and i did what any self respecting male would do at this point, having surveyed the damage i grabbed her and stuck her head under the cold tap to reduce the effects of the heat until she couldn't stand the effects of the cold water any more, it also seemed to have a calming effect and once she had realised that she hadn't lost all her hair ( just a large part of her fringe)!!! she soon calmed down an i am very glad to say that there is no lasting damage

but it just goes to show how a simple task can sometimes turn really nasty.

I had to do that with my wife too, she wasn't on fire - I just didn't like her anymore. And now I keep a bucket of water by the back door for similar emergencies or just in case she comes back.

Hi all,
Spent quite a lot of time this week preparing the engine bay, cut all the excess bolt lengths from the drives & trim tabs as these are made to fit a variety of transom thicknesses they were all far too long for our installation. Have also decided to bury all the non structural mounting bolts into the engine bearers these will be potted in epoxy bonding paste giving a very clean look also as the bolts become captive you will only need one spanner. I also made a tool to spot face the inside of the transom where the bulkhead fittings for the water drains enter as these were not quite square with the outside.

peterunwin · 31-10-2010, 11:20 AM

Hi All,
At last i have finished the processes which make a tremendous amount of dust, these have involved enlarging the exhaust outlet holes,machining out the foam between the bulkhead apertures and making good with epoxy bonding paste also took the opportunity to reduce the flange depth round the engine hatch aperture these along with the bolt offcuts have resulted in a weight saving of just over 5kilos.During next week i will be planning the installation of the bilge pumps, there will be one electric and one manual in the engine bay a manual in the tank compartment and a manual in the cabin, these will be installed using the shortest possible hose runs. We now have a massive cleanup operation after which it should become a much more pleasant place to work

Hi All,
Made great progress this week installing all the bilge pumps, these have been temporarily installed so that i can drill all the mounting holes and cut the pipes. As can be seen from the photographs the pipes are very short, the engine bay pumps are fitted with non return valves with the exit through the transom above the water line, the manual pump in the engine bay will be operated by a pushrod underneath the starboard engine to a convenient position. Also removed all the transom bulkhead fittings and applied two coats of epoxy resin to the holes prior to fitting them permanently, should be able to start painting next week.

fantastic attention to detail

but Peter the gauntlet has been laid down by that fantastic record run by the guys in Cinzano with simular engines and also powering a non stepped hull, although Cinzano is out and out race boat the Hunton does benefit with all the latest light weight build techniques ... the race is on

biffer · 04-11-2010, 10:21 AM

hope your alarm, immobiliser and tracker get's the same attention to detail

peterunwin · 09-11-2010, 07:54 PM

Hi All,
Made up the outlets for the engine bay bilge pumps, these comprise of a stainless steel outlet a short piece of plastic pipe and a plastic elbow on the inside, these were all carefully assembled with 2-pack epoxy glue to make sure there was absolutley no voids that would allow any water ingress into the core of the transom, also took the opportunity to bond all the mounting bolts into the engine beds with the epoxy as well. The 2-pack epoxy paint arrived today so i will be doing a trial possibly tomorrow.
