Why not use the tube to mould it off - it's the shape you need!

Like this? Plastic sheet on the tube then fibreglass over the plastic.Except using the front end of the RIB collar.

Started the plug with a rough foam core just as a former and then applied a bonding coat to get again the rough shape in situ in a mould.

plaster finish coat to post.

When dry I was thinking 2 coats of resin and a wet and dry sand down before g7 cutting polish and wax before starting the mould.

Are you not creating a headache for yourself now having to have tubes made to fit your nose? Surely it would be better to have tubes first and take the dimensions from them? Each to there own and all that!

I am in contact with the company that will be suppling and fitting the tubes.
They have given me instructions as to their requirements .

So i have taken their advise so far as size of tubes and what they would like in order to fit them.

The plug for the nose has NO holes cut so the tube sockets can be fitted when or if i ever get it completed.

any thing from a 1 mtr radius to a radius of 1.250 .

as for stuff used to form a plug well it is a home build .

The foam used are insulation cavity boards the foam was cut using a kitchen waste bin as the template.

the lip moulding to attach the tubes to the rear of the transom "shock horror" again will be formed using the inside of the bin for a mould.

and the list i dare say will go on and on as home builds do.

However using odd items found around the home to assist in formwork does not mean the boat will be badly made.

The well at the rear for the bilge pump i was thinking moulding the outside of a plastic tupperware container.
The battery box well another moulding from some other item around the house.

As you said i guess i will never get to use it but I so far have enjoyed doing what I can on it and have a bit of time to waste.

The mould itself SPLASH is near on finished now .
when it comes to spending real money on the grp and other items A mate is paying for it as it will be his when it's finished.

Great fun.

From Sisyphus < Ancient Greek Σίσυφος (Sisuphos). Sisyphus was a Greek mythological figure who was doomed to endlessly roll a boulder up a hill in Hades.
where there is a will there is a way.
