doing a similar project myself with a workboat - contemplating using jim more designs for a complete plug kit, am interested to see how yours comes along

good luck
Hi Neville,

We did consider it, and Kitten has got very proficient at Rhino (the 3D drawing package) now, but we are cutting it all to fit - as usual with these things the fiddly bits are the steps, and that bit is well on the way to being done, the rest of the bottom is fairly flat which is straightforward.

Don't know the kit you're talking about, but it sounds interesting - do you get the skin with that package?

we initially priced a wooden female mould kit with a company in italy, and were quite tempted, but i didnt fancy the idea of refinishing the inside of the mould, these come with foundations, cladding etc and allegedly just slot together. check out www.3dwmoulds.com


It now looks like we will be going with this other company called Jim More Designs who are uk based and have provided plug kits for alot of racing yachts etc.

I believe they can come with or without the cladding.

Im a little bit aprehensive about the project in case we slip up, and we do like to rush things as time is money as im sure you will be more than aware !

Are you coating your plug with GRP ?

Cheers

Sounds interesting, which boat are you looking at building? If you don't mind me asking what sort of cost (PM or email me if you prefer) is this system and what do you get? It looks like you will have a female mould instead of a plug to make a mould, that means you will be dealing with concave surfaces rather than convex ones, which are a little harder to get nice and flat - but I don't know the process or your skill levels!

Our plug will either be painted with high build paint, then sanded and polished or laminated with shiny Formica or a combination of both which is most likely, then we will take a mould off that to make the boat from.

Gtflash - the cladding or skin is the surface you take a mould off that goes over the frame - the mould for the steps was made this way with a high build paint polished to a shiny surface.

3D machining is the preferred option, it is undoubtedly much faster if the lead time is not too great but is costly compared to the method we have used. In addition the foam plug then has to be coated in a material hard enough to take a mould off which is more money - I believe the material itself is expensive - I have not seen how good the machine finish is, but I believe some hand finishing is still required with this method. If we had the money we would follow this route without a doubt.

A few more photos to show what's been happening recently - the hull is now covered with shiny white stuff (stuck 9on with spray on contact adhesive) and the spray rails have been fitted.

Thanx for the update Cookee. What is 9on - a non-stick/mould release surface?

The shiny white stuff is just Formica as you would put on your kitchen top, it provides a great hard shiny surface for taking a mould off, and we have used it for some time for making plugs.

A bit more progress - the two rear sections of spray rails are now covered in Formica and the curved forward rails are painted and polished, the whole running surface has been polished and the sides are now on and flat and waiting for the "Formica Treatment".

Once all of that is done the next stage will be attaching the flange and making the hull mould, turning it over and starting on the other side.

The boat will be "Seamless" with no rubrail so it will be joined from the inside whilst all being still in the moulds - the first time we will see the finished boat it will come out all joined together!
