Split Mould Building
« on: January 06, 2007, 01:18:43 AM »
Leov, I read the article on Peter Scandling's split mould constructed Mini. I found it very interesting. Do you know what materials he used and where one can findout more information on this process? Thanks

No idea, a pity Peter had to leave the mini scene due to health.
I think it was a carbon,foam boat.

Leov, Do you know if there were any structural issues with the boat in actual sailing.
Is his boat still racing?
Thanks
Randy

Split centre line building has been around for ages in the multihull world and I dont know of any structural problems related to the build method.  As for my old boat she was registered with the hull no.397 and sold to a guy in plymouth uk.  That however was the last I heard.... and i live in plymouth. the boat seems to have vanished would love to find out more about her.

Lots of mono hulls are built in a split mould. Specially production boats. i dont know of any problems with this kind of building.

Thank you for your comments. I have been researching the split mould method and as you say it is used in a number of builds. I see that there is an open 50 recently build this way.
I am curious as to the materials you used.

In my particular case I used glass foam and epoxy.  The method can be used with any of the available materials. Leo good to be back.

 How was the join performed. What I have read in other builds indicates that in that area the layers of Epoxy and glass are cut back in the half moulds and then added back over the joint when bonding them together. Aprox how wide was the join area. Is the distribution of material evan between the inside and the out side of the joint.
I am considering building a boat and am limited in space. Your method of construction would work.

Thanks for any information.

I did not do anything that has not been tried before. along the length of the joint you cut a rebate the depth of the glass/carbon in use and the width will depend on your engineer. in my case we put 3 inches either side of the join on the outside  and inside we used two layers, one of 3 inches and one of 6.

As I said in the article the main advantage is space.  You could build a mini in a container using a split centre line mould.
cheers
