Do you want to help?

It won't be as bling as yours, and it won't take as long - wish we had the time!

What I ment was nice to see the polished pipes on the outside of the boat, but heyho either is good.

what he said above, and bring your tool box

Hi All,
Spent most of today drilling holes and installing a ring of pvc pipework in the engine bay, this will be used to conceal all of the engine bay wiring,only the battery leads and the engine harnesses will be visible.I also drilled the holes required to run the control cables through. I collected a 60 metre coil of low friction control cable which i will use to tailor-make each cable in the most economical way.

Hi All,
Couldn't find anywhere level to mount the tab indicators so had to make an angled plinth for installation next to the compass, also tailor made all the outer control cables, these will be labelled then removed and sent back to the manufacturer for installation of the inner cables and swaging.

Here's a motor that will completely take your mind of boating costs, might even make boating seem like a boring form of water caravanning even with Ilmor's ... a snip at £650K

Hi All,
Been doing a bit of work on the steering transducer installation.My original intention was to use linear transducers mounted inside the steering cylinders but unfortunately there isn't sufficient room for this to be practical,so i am installing rotary transducers.To achieve the drive mechanism i have removed the top pivot pins and drilled a 6mm hole through the centre, at each end of the hole we have machined a recess for a quad ring seal.The movement of the gimble ring is transmitted to the transducer via a 6mm titanium rod welded to a titanium tag which in turn is bolted to the gimble ring.

So this is steering indicator. The rod will go into the hull and turn a potentiometer pot and you can read the ohms to determine the steering movement?

Hi All,
Made a few more parts for the transducer installation these will allow the mounting of the transducers inside the bathing platform.

Hi all,
Started making up the battery and trim pump leads. Even though the leads are as short as possible i am using large cross sectional, ultra flexible cable with heavy duty insulation.The terminals i use are modified solder type which i attach to the cable by swaging on a stainless steel hydraulic hose ferrel and finish of with a piece of heat shrink making a neat and completely watertight termination.

What's the reason for not just soldering them on? I've always preferred that to 'clamping' to the cable in any way. That said, I don't have access to hydraulic bits!

At the very begging of this project Peter had you intended to get it water-born for the CTC with all the other new boats (although not to race) ... however its amazing to watch all this work going in to the project

Is that sales speak for 'welding cable'?

Hi James,
I always used to solder the ends but found the very fine ultra flexible cable can fracture at the end of the soldered joint if it is subject to harsh vibration, so about 15years ago i started swaging all my battery leads and have never had a problem, the joint is a progressive swage with the very end part being compressed to solid and the the outboard end is a more relaxed swage giving very good flexibilty.

Hi cfun,
The original intention was to have it ready for march 2010 which would have been the 3 year aniversary of the old Cheetah but Ilmor were very late in delivering the engines so we missed that one!!! also as the project has evolved i am making more and more custom parts which all takes time, we also lost about 4 weeks whilst working on Cinzano so the plan now is to nurse the old Cheetah to the end of the season and then take her back to the Midlands for a makeover and use the same transport as a return load for Carbon Cheetah not sure on dates yet!!

Hi Downhilldai,
Yes it is very similar to welding cable with a different colour insulation.

May i ask , how did you fit the pipe's in the engine bay to the hull ?

Your work looks more than excelent i am folowing every step of your build here , keep the picture's comming

Hi ph@ntastic,
At the moment the pipes are supported by the holes in the bulk heads and engine bearers but when they are installed permanently i will use stainless steel hose clips with tags welded onto them screwed to the inner core of the hull.

Peter

[Ph@ntastic]

Thanks for that info and keep up the good work

Kind regards , Jurry

Hi All,
I made up the power supply wiring harnesses for the trim & tab pumps, after the terminals were swaged onto the wires i applied two layers of heat shrink sleeving to give good insulation, when i do the final assembly all the terminal nuts will have push on plastic covers to guard against accidental shorting, i also wasted one terminal and sectioned it to establish the correct swaging size.

What make are those solenoids? Never seen ones like that before...
