Looks pretty good Cameron. You might want to check your width to length ratio though. Short and wide (like all wheeled things) is maneuverable and twitchy (think go kart) long and narrow is directionally stable(think dragster). Yours looks a bit too short to me. Foot pedal looks a bit too short to. If it's too small they get really sensitive.
Your next drawing (elevation?) will give us more to comment on. Keep it up.

as I dont have a side view I'll assume mini style layover steering. pedal width is just right for this type of steering but it is preferable to have the seat extend UNDER the foot pedals to avoid accidental foot slippage to the ground.
doing well mate!

Hi Paul, using the wheel width dimension as a guide (the foot pedals don't have one) it looks close to 200mm foot pedal width to the foot pads. Now you have used these but with my little size 8s means my feet touch each other?

without looking at the plans. I think the pedals are 300 wide. with a bit of paper on the screen I measured about 290.
when you use this steering you will suprised by the lack of movement to get the yacht to do lots of turning.
TEST PILOT 1 has just cut out the pedals to fit his new mini AND his extra wide size 10's. wider pedals are actually a bad thing on this steering.
Theres a you tube video of an "explorer " sailing through the flags in the general section.Have a look at how little foot movement there is

2.6m long and 1. 1.85m width ? what do you recommend for the length

what he said

1640mm is only the length of the steel chassis, not the overall length. Remember the seat protrudes past the rear end of the chassis some distance. Im about the same height as you and I'll fit in my mini when finished, as do the other mini pilots in their machines.

ohk ok ill change my plans to suit that then and guess what I BOUGHT A SAIL!!!
not sure of the exact dimensions but i got sail , boom and mast + board :P for 150 dollars

Excellent, well done! You've gone past the point of no return now!

Anyone got ideas for materials ?

All steel.

Nominal 60 mm x 1.6 mm or 2mm wall galvanised tube for the centre spine and mast step.

Gal 35mm x 35mm 1.6mm or 2mm wall RHS (Rightangle Hollow Section) for rear X member, fork head and fork.

Gal 30mm x 30mm 1.6mm or 2mm wall RHS for axle extensions.

Gal 20mm water pipe for steering shaft and axles.

Nylon for steering shaft bearings.

Use of 1.6mm material will result in an approximate 20% lighter chassis and from experience appears to be strong enough.

Copy and paste the above into your BOM (Bill Of Materials) and you will have it right and save you some typing.
Cheers Cisco

Hi guys, are you sure about "rightangle hollow section", the rest of the world is "rectangular hollow section". But then all the world is not the same thank goodness!

Ohk thanks
What are the "axel extensions"
why would i use water pipe for axels and steering?

Try to ignore the attachment of the axles though. Diablo still has 1" threaded rod axles which are not on the same axis of the extension tube. It has not been very successful so I am going to try what Kody suggested in this thread

Re the gal water pipe for axles and steer shaft. It is for the reasons that SN stated however I need to correct what I said a little.

For the steer shaft, if 1" nominal gal water pipe should be used and if the fork head is 35mm RHS it should be possible to have nylon fork head bearings. If the fork head is of 30mm RHS the 1" pipe is a neat fit but the head will need washers welded on top and bottom. Look in here for details. www.seabreeze.com.au/forums/topic.asp?TOPIC_ID=48684

Gal water pipe of a nominal size varies in size by wall thickness. This changes the exact ID and OD of the pipe. I used the water pipe because I was able to find just the right size in which I could insert a handle bar clamp from a bicycle. This saved me a lot of fiddly fabrication. That size was also a neat fit in the 30mm RHS.

I suggested the 20mm water pipe for the axles for the reasons SN stated, however I am not sure that such a size exists. If it does you need to make sure your 6204 bearing is a neat fit on it. If the water pipe is not suitable you can try steel electrical conduit. If THAT does not work you will have to go to solid shaft, bolts or threaded rod.

If that lot has not confused you I can try rewriting it in Chinese. Cheers Cisco

rather a sad little comment there wanabee, getting in the way of cameron building his yacht,.

20mm OD electrical conduit is a great fit

Thanks for that gem Paul. I am sure Ando's Electrical has heaps of off cuts of it, off off off fink.
