pictures of the new sail

Yeah its in really good condtion exexpt for the plastic stuff on the sail is comming off a little but for 150 dollars for all that i thought was a good deal ( exept the surfboards in the background)
ohk so i just use that forum how to cut the sail?
the sail is 4.8x1.83 or something

Yeah me and a couple of friends went and tryed to windsurf hmmm didnt work all that well haha , once i cut the sail and everything i wont be able to use it for windsurfing anymore will i?

I was thinking about taking all the foot straps off and taking out the center board and fibreglassing it smooth and turn it into a paddle board.

how long mast step be and how far from the rear x member

Good advice there Lachy. I did it before I built.

is the mast step the tube that the mast slides into?
how does the mast go into the mast step becuase at the bottom of the mast it has a steel section where it tensions the sail.?
now all i need to do is write a cutting list

The mast should just slide into the mast step until it bottoms out on the main chassis spine (which the mast step is welded onto.)
On my lefroy mini the mast is a pretty sloppy fit, so I used a piece of thin walled plastic plumbing pipe as a sleeve between the mast and the mast step tube to take up some of the slop.

urethane bushes for steering shaft:

40mm O.D. X 20mm I.D.

part no. 90389-14056P made by "TERRAIN TAMER" I think they are landcruiser suspension bushes. you will need 2 of them.

Then you need to find a piece of 40mm I.D. steel tube about 120mm to 130mm long for the bushes to be pressed into to make the steering head.

Cameron, have you printed out a set of plans yet?
If not ...you will need to.

Once you have printed a copy have, take your time and have a close look at them. ALL the measurements are there.

yes i printed them all out

For DNT you need an invovation and i was thinking my innovation should be a weldless landyacht so i can pull it appart and pack it away easyily would this work any good?

i think im going to do it this way

have a plate welded onto the center spine and a plate the same size welded onto the bottom of the mast step and bolt it on.
same thing to join the rear x member to the spine
have removable axle extensions
and removable front wheel etc

should be alright

got some steel yesterday some of it is a little bit thicker eg 2.2mm and 65x65 instead of 60x60 i hope its not going to be to heavy?

Making the rear axle set up removable could work nicely , given the materials youve chosen .
I wouldnt recommend making the mast step removable. this is the most stressed point on the yacht and would require really heavy plates . a couple of the lads have tried it and inevitably something bends or breaks

im going to weld the mast step just because its really not that long and will be easy as to transport.

Got a quote from a fibreglassing supply shop in QLD for 2.5 sqm of fibreglass to do 2 layers of chopped strand fibreglass with 10 litres of resin and a coat of flowcoat and blue pigment i will order probably on monday

Ive never use flow coat as it is applied as a coating to finish the seat.
personally ive found that a coat of etch primer and then just enamel paint is a good alternative. anybody else have thoughts on that one. the pigment seemed a bit pricey.
dont forget to cost in the catalyst, some brushes , acetone(1/2 L) a box of gloves from the supermarket and a little fibreglass roller

ohk i dont know how but for some reason i thought i needed to order 60x60 mm RHS for rear cross member when i really needed 35x35 hmmmmmm would the 60x60 work or would it be to heavy. i wondered why the cross member was so much bigger then the axel extensions.

What should i do cut up the pience of 60x60 and use it for test welding?

i think having a 60mm wide center spine round tube going onto a 60x60 rear x member would make it alot easyer to weld but adding a little more weight but this would allow me to add the "skii's when i ever need to and i think my seat should be farly light so should be under the 35kgs

ohk i am going to get this now
